Member Enumeration Documentation

◆ ColourIds

enum juce::TextEditor::ColourIds

A set of colour IDs to use to change the colour of various aspects of the editor.

These constants can be used either via the Component::setColour(), or LookAndFeel::setColour() methods.

NB: You can also set the caret colour using CaretComponent::caretColourId

See also: Component::setColour, Component::findColour, LookAndFeel::setColour, LookAndFeel::findColour

Enumerator
backgroundColourId	The colour to use for the text component's background - this can be transparent if necessary.
textColourId	The colour that will be used when text is added to the editor. Note that because the editor can contain multiple colours, calling this method won't change the colour of existing text - to do that, use the applyColourToAllText() method
highlightColourId	The colour with which to fill the background of highlighted sections of the text - this can be transparent if you don't want to show any highlighting.
highlightedTextColourId	The colour with which to draw the text in highlighted sections.
outlineColourId	If this is non-transparent, it will be used to draw a box around the edge of the component.
focusedOutlineColourId	If this is non-transparent, it will be used to draw a box around the edge of the component when it has focus.
shadowColourId	If this is non-transparent, it'll be used to draw an inner shadow around the edge of the editor.

Constructor & Destructor Documentation

◆ TextEditor()

juce::TextEditor::TextEditor	(	const String &	componentName = `String()`,
		juce_wchar	passwordCharacter = `0`
	)

explicit

Creates a new, empty text editor.

Parameters

componentName	the name to pass to the component for it to use as its name
passwordCharacter	if this is not zero, this character will be used as a replacement for all characters that are drawn on screen - e.g. to create a password-style textbox containing circular blobs instead of text, you could set this value to 0x25cf, which is the unicode character for a black splodge (not all fonts include this, though), or 0x2022, which is a bullet (probably the best choice for linux).

Definition at line 933 of file juce_TextEditor.cpp.

◆ ~TextEditor()

juce::TextEditor::~TextEditor ( )

override

Destructor.

Definition at line 949 of file juce_TextEditor.cpp.

Member Function Documentation

◆ addListener()

void juce::TextEditor::addListener ( Listener * newListener )

Registers a listener to be told when things happen to the text.

See also: removeListener

Definition at line 1326 of file juce_TextEditor.cpp.

◆ addPopupMenuItems()

void juce::TextEditor::addPopupMenuItems	(	PopupMenu &	menuToAddTo,
		const MouseEvent *	mouseClickEvent
	)

virtual

This adds the items to the popup menu.

By default it adds the cut/copy/paste items, but you can override this if you need to replace these with your own items.

If you want to add your own items to the existing ones, you can override this, call the base class's addPopupMenuItems() method, then append your own items.

When the menu has been shown, performPopupMenuAction() will be called to perform the item that the user has chosen.

The default menu items will be added using item IDs from the StandardApplicationCommandIDs namespace.

If this was triggered by a mouse-click, the mouseClickEvent parameter will be a pointer to the info about it, or may be null if the menu is being triggered by some other means.

See also: performPopupMenuAction, setPopupMenuEnabled, isPopupMenuEnabled

Definition at line 1804 of file juce_TextEditor.cpp.

◆ applyColourToAllText()

void juce::TextEditor::applyColourToAllText	(	const Colour &	newColour,
		bool	changeCurrentTextColour = `true`
	)

Applies a colour to all the text in the editor.

If the changeCurrentTextColour argument is true then this will also set the new colour as the colour to be used for any new text that's added.

Definition at line 1108 of file juce_TextEditor.cpp.

◆ applyFontToAllText()

void juce::TextEditor::applyFontToAllText	(	const Font &	newFont,
		bool	changeCurrentFont = `true`
	)

Applies a font to all the text in the editor.

If the changeCurrentFont argument is true then this will also set the new font as the font to be used for any new text that's added.

See also: setFont

Definition at line 1089 of file juce_TextEditor.cpp.

◆ areScrollbarsShown()

bool juce::TextEditor::areScrollbarsShown ( ) const

See also: cut, paste, SystemClipboard

Definition at line 1679 of file juce_TextEditor.cpp.

◆ copyToClipboard()

bool juce::TextEditor::copyToClipboard ( )

Definition at line 2108 of file juce_TextEditor.cpp.

◆ createAccessibilityHandler()

std::unique_ptr< AccessibilityHandler > juce::TextEditor::createAccessibilityHandler ( )

overridevirtual

Override this method to return a custom AccessibilityHandler for this component.

The default implementation creates and returns a AccessibilityHandler object with an unspecified role, meaning that it will be visible to accessibility clients but without a specific role, action callbacks or interfaces. To control how accessibility clients see and interact with your component subclass AccessibilityHandler, implement the desired behaviours, and return an instance of it from this method in your component subclass.

The accessibility handler you return here is guaranteed to be destroyed before its Component, so it's safe to store and use a reference back to the Component inside the AccessibilityHandler if necessary.

This function should rarely be called directly. If you need to query a component's accessibility handler, it's normally better to call getAccessibilityHandler(). The exception to this rule is derived implementations of createAccessibilityHandler(), which may find it useful to call the base class implementation, and then wrap or modify the result.

See also: getAccessibilityHandler

Reimplemented from juce::Component.

Definition at line 2772 of file juce_TextEditor.cpp.

◆ cut()

void juce::TextEditor::cut ( )

Deletes the currently selected region.

This doesn't copy the deleted section to the clipboard - if you need to do that, call copy() first.

◆ keyPressed()

bool juce::TextEditor::keyPressed ( const KeyPress & key )

overridevirtual

Called when a key is pressed.

When a key is pressed, the component that has the keyboard focus will have this method called. Remember that a component will only be given the focus if its setWantsKeyboardFocus() method has been used to enable this.

If your implementation returns true, the event will be consumed and not passed on to any other listeners. If it returns false, the key will be passed to any KeyListeners that have been registered with this component. As soon as one of these returns true, the process will stop, but if they all return false, the event will be passed upwards to this component's parent, and so on.

The default implementation of this method does nothing and returns false.

See also: keyStateChanged, getCurrentlyFocusedComponent, addKeyListener

Reimplemented from juce::Component.

Definition at line 2144 of file juce_TextEditor.cpp.

◆ keyStateChanged()

bool juce::TextEditor::keyStateChanged ( bool isKeyDown )

overridevirtual

Called when a key is pressed or released.

Whenever a key on the keyboard is pressed or released (including modifier keys like shift and ctrl), this method will be called on the component that currently has the keyboard focus. Remember that a component will only be given the focus if its setWantsKeyboardFocus() method has been used to enable this.

If your implementation returns true, the event will be consumed and not passed on to any other listeners. If it returns false, then any KeyListeners that have been registered with this component will have their keyStateChanged methods called. As soon as one of these returns true, the process will stop, but if they all return false, the event will be passed upwards to this component's parent, and so on.

The default implementation of this method does nothing and returns false.

To find out which keys are up or down at any time, see the KeyPress::isKeyCurrentlyDown() method.

Parameters

isKeyDown true if a key has been pressed; false if it has been released

See also: keyPressed, KeyPress, getCurrentlyFocusedComponent, addKeyListener

Reimplemented from juce::Component.

Definition at line 2189 of file juce_TextEditor.cpp.

◆ lookAndFeelChanged()

void juce::TextEditor::lookAndFeelChanged ( )

overridevirtual

Called to let the component react to a change in the look-and-feel setting.

When the look-and-feel is changed for a component, this method, repaint(), and colourChanged() are called on the original component and all its children recursively.

It can also be triggered manually by the sendLookAndFeelChange() method, in case an application uses a LookAndFeel class that might have changed internally.

See also: sendLookAndFeelChange, getLookAndFeel

Reimplemented from juce::Component.

Definition at line 1119 of file juce_TextEditor.cpp.

◆ mouseDoubleClick()

void juce::TextEditor::mouseDoubleClick ( const MouseEvent & event )

overridevirtual

Called when a mouse button has been double-clicked on a component.

The MouseEvent object passed in contains lots of methods for finding out which button was pressed, as well as which modifier keys (e.g. shift, ctrl) were held down at the time.

Parameters

A mouseUp callback is sent to the component in which a button was pressed even if the mouse is actually over a different component when the button is released.

The MouseEvent object passed in contains lots of methods for finding out which buttons were down just before they were released.

Parameters

event details about the position and status of the mouse event, including the source component in which it occurred

See also: mouseDown, mouseDrag, mouseDoubleClick, contains

◆ mouseWheelMove()

void juce::TextEditor::mouseWheelMove	(	const MouseEvent &	event,
		const MouseWheelDetails &	wheel
	)

overridevirtual

Called when the mouse-wheel is moved.

This callback is sent to the component that the mouse is over when the wheel is moved.

If not overridden, a component will forward this message to its parent, so that parent components can collect mouse-wheel messages that happen to child components which aren't interested in them. (Bear in mind that if you attach a component as a mouse-listener to other components, then those wheel moves will also end up calling this method and being passed up to the parents, which may not be what you intended to happen).

Parameters

event	details about the mouse event
wheel	details about the mouse wheel movement

◆ paint()

void juce::TextEditor::paint ( Graphics & g )

overridevirtual

Components can override this method to draw their content.

The paint() method gets called when a region of a component needs redrawing, either because the component's repaint() method has been called, or because something has happened on the screen that means a section of a window needs to be redrawn.

Any child components will draw themselves over whatever this method draws. If you need to paint over the top of your child components, you can also implement the paintOverChildren() method to do this.

If you want to cause a component to redraw itself, this is done asynchronously - calling the repaint() method marks a region of the component as "dirty", and the paint() method will automatically be called sometime later, by the message thread, to paint any bits that need refreshing. In JUCE (and almost all modern UI frameworks), you never redraw something synchronously.

You should never need to call this method directly - to take a snapshot of the component you could use createComponentSnapshot() or paintEntireComponent().

Parameters

g	the graphics context that must be used to do the drawing operations.

See also: repaint, paintOverChildren, Graphics

Reimplemented from juce::Component.

Definition at line 1777 of file juce_TextEditor.cpp.

◆ paintOverChildren()

void juce::TextEditor::paintOverChildren ( Graphics & g )

overridevirtual

Components can override this method to draw over the top of their children.

For most drawing operations, it's better to use the normal paint() method, but if you need to overlay something on top of the children, this can be used.

See also: paint, Graphics

Reimplemented from juce::Component.

Definition at line 1782 of file juce_TextEditor.cpp.

◆ parentHierarchyChanged()

void juce::TextEditor::parentHierarchyChanged ( )

overridevirtual

Called to indicate that the component's parents have changed.

When a component is added or removed from its parent, this method will be called on all of its children (recursively - so all children of its children will also be called as well).

Subclasses can override this if they need to react to this in some way.

◆ paste()

void juce::TextEditor::paste ( )

Pastes the contents of the clipboard into the editor at the caret position.

See also: cut, copy, SystemClipboard

Definition at line 1690 of file juce_TextEditor.cpp.

◆ pasteFromClipboard()

bool juce::TextEditor::pasteFromClipboard ( )

Definition at line 2123 of file juce_TextEditor.cpp.

◆ performPopupMenuAction()

void juce::TextEditor::performPopupMenuAction ( int menuItemID )

virtual

This is called to perform one of the items that was shown on the popup menu.

If you've overridden addPopupMenuItems(), you should also override this to perform the actions that you've added.

If you've overridden addPopupMenuItems() but have still left the default items on the menu, remember to call the superclass's performPopupMenuAction() so that it can perform the default actions if that's what the user clicked on.

◆ redo()

bool juce::TextEditor::redo ( )

Definition at line 989 of file juce_TextEditor.cpp.

◆ removeListener()

void juce::TextEditor::removeListener ( Listener * listenerToRemove )

Deregisters a listener.

See also: addListener

Definition at line 1327 of file juce_TextEditor.cpp.

◆ resized()

void juce::TextEditor::resized ( )

overridevirtual

Called when this component's size has been changed.

A component can implement this method to do things such as laying out its child components when its width or height changes.

The method is called synchronously as a result of the setBounds or setSize methods, so repeatedly changing a components size will repeatedly call its resized method (unlike things like repainting, where multiple calls to repaint are coalesced together).

If the component is a top-level window on the desktop, its size could also be changed by operating-system factors beyond the application's control.

See also: moved, setSize

Reimplemented from juce::Component.

Definition at line 2244 of file juce_TextEditor.cpp.

◆ returnPressed()

void juce::TextEditor::returnPressed ( )

protectedvirtual

Can be overridden to intercept return key presses directly.

Definition at line 1323 of file juce_TextEditor.cpp.

◆ scrollDown()

bool juce::TextEditor::scrollDown ( )

Definition at line 2054 of file juce_TextEditor.cpp.

◆ scrollEditorToPositionCaret()

void juce::TextEditor::scrollEditorToPositionCaret	(	int	desiredCaretX,
		int	desiredCaretY
	)

Attempts to scroll the text editor so that the caret ends up at a specified position.

This won't affect the caret's position within the text, it tries to scroll the entire editor vertically and horizontally so that the caret is sitting at the given position (relative to the top-left of this component).

Depending on the amount of text available, it might not be possible to scroll far enough for the caret to reach this exact position, but it will go as far as it can in that direction.

Definition at line 1415 of file juce_TextEditor.cpp.

◆ scrollToMakeSureCursorIsVisible()

void juce::TextEditor::scrollToMakeSureCursorIsVisible ( )

protected

Scrolls the minimum distance needed to get the caret into view.

Definition at line 1550 of file juce_TextEditor.cpp.

◆ scrollUp()

bool juce::TextEditor::scrollUp ( )

Definition at line 2060 of file juce_TextEditor.cpp.

◆ selectAll()

bool juce::TextEditor::selectAll ( )

Definition at line 2130 of file juce_TextEditor.cpp.

◆ setBorder()

void juce::TextEditor::setBorder ( BorderSize< int > border )

Changes the size of border left around the edge of the component.

See also: getBorder

Definition at line 1534 of file juce_TextEditor.cpp.

◆ setCaretPosition()

void juce::TextEditor::setCaretPosition ( int newIndex )

Moves the caret to be in front of a given character.

See also: getCaretPosition, moveCaretToEnd

Definition at line 1405 of file juce_TextEditor.cpp.

◆ setCaretVisible()

void juce::TextEditor::setCaretVisible ( bool shouldBeVisible )

Makes the caret visible or invisible.

By default the caret is visible.

See also: setCaretColour, setCaretPosition

Definition at line 1136 of file juce_TextEditor.cpp.

◆ setClicksOutsideDismissVirtualKeyboard()

void juce::TextEditor::setClicksOutsideDismissVirtualKeyboard ( bool newValue )

Sets the behaviour of mouse/touch interactions outside this component.

If true, then presses outside of the TextEditor will dismiss the virtual keyboard. If false, then the virtual keyboard will remain onscreen for as long as the TextEditor has keyboard focus.

Definition at line 1036 of file juce_TextEditor.cpp.

◆ setEscapeAndReturnKeysConsumed()

void juce::TextEditor::setEscapeAndReturnKeysConsumed ( bool shouldBeConsumed )

noexcept

This can be used to change whether escape and return keypress events are propagated up to the parent component.

The default here is true, meaning that these events are not allowed to reach the parent, but you may want to allow them through so that they can trigger other actions, e.g. closing a dialog box, etc.

Definition at line 2139 of file juce_TextEditor.cpp.

◆ setFont()

void juce::TextEditor::setFont ( const Font & newFont )

Sets the font to use for newly added text.

This will change the font that will be used next time any text is added or entered into the editor. It won't change the font of any existing text - to do that, use applyFontToAllText() instead.

See also: applyFontToAllText

Definition at line 1083 of file juce_TextEditor.cpp.

◆ setHighlightedRegion()

void juce::TextEditor::setHighlightedRegion ( const Range< int > & newSelection )

overridevirtual

Selects a section of the text.

Implements juce::TextInputTarget.

Definition at line 1667 of file juce_TextEditor.cpp.

◆ setIndents()

void juce::TextEditor::setIndents	(	int	newLeftIndent,
		int	newTopIndent
	)

Changes the size of the gap at the top and left-edge of the editor.

By default there's a gap of 4 pixels.

Definition at line 1522 of file juce_TextEditor.cpp.

◆ setInputFilter()

void juce::TextEditor::setInputFilter	(	InputFilter *	newFilter,
		bool	takeOwnership
	)

Sets an input filter that should be applied to this editor.

The filter can be nullptr, to remove any existing filters. If takeOwnership is true, then the filter will be owned and deleted by the editor when no longer needed.

Definition at line 1194 of file juce_TextEditor.cpp.

◆ setInputRestrictions()

void juce::TextEditor::setInputRestrictions	(	int	maxTextLength,
		const String &	allowedCharacters = `String()`
	)

Sets limits on the characters that can be entered.

This is just a shortcut that passes an instance of the LengthAndCharacterRestriction class to setInputFilter().

Parameters

maxTextLength	if this is > 0, it sets a maximum length limit; if 0, no limit is set
allowedCharacters	if this is non-empty, then only characters that occur in this string are allowed to be entered into the editor.

Definition at line 1199 of file juce_TextEditor.cpp.

◆ setJustification()

void juce::TextEditor::setJustification ( Justification newJustification )

Modifies the justification of the text within the editor window.

Definition at line 1071 of file juce_TextEditor.cpp.

◆ setKeyboardType()

void juce::TextEditor::setKeyboardType ( VirtualKeyboardType type )

noexcept

Sets the type of virtual keyboard that should be displayed when this editor has focus.

Definition at line 680 of file juce_TextEditor.h.

◆ setLineSpacing()

void juce::TextEditor::setLineSpacing ( float newLineSpacing )

noexcept

Sets the line spacing of the TextEditor.

The default (and minimum) value is 1.0 and values > 1.0 will increase the line spacing as a multiple of the line height e.g. for double-spacing call this method with an argument of 2.0.

Definition at line 542 of file juce_TextEditor.h.

◆ setMultiLine()

void juce::TextEditor::setMultiLine	(	bool	shouldBeMultiLine,
		bool	shouldWordWrap = `true`
	)

Puts the editor into either multi- or single-line mode.

By default, the editor will be in single-line mode, so use this if you need a multi-line editor.

See also the setReturnKeyStartsNewLine() method, which will also need to be turned on if you want a multi-line editor with line-breaks.

Parameters

shouldBeMultiLine	whether the editor should be multi- or single-line.
shouldWordWrap	sets whether long lines should be broken up in multi-line editors. If this is false and scrollbars are enabled a horizontal scrollbar will be shown.

See also: isMultiLine, setReturnKeyStartsNewLine, setScrollbarsShown

Definition at line 992 of file juce_TextEditor.cpp.

◆ setPasswordCharacter()

void juce::TextEditor::setPasswordCharacter ( juce_wchar passwordCharacter )

Changes the password character used to disguise the text.

Parameters

passwordCharacter if this is not zero, this character will be used as a replacement for all characters that are drawn on screen - e.g. to create a password-style textbox containing circular blobs instead of text, you could set this value to 0x25cf, which is the unicode character for a black splodge (not all fonts include this, though), or 0x2022, which is a bullet (probably the best choice for linux).

Definition at line 1210 of file juce_TextEditor.cpp.

◆ setPopupMenuEnabled()

void juce::TextEditor::setPopupMenuEnabled ( bool menuEnabled )

Allows a right-click menu to appear for the editor.

(This defaults to being enabled).

If enabled, right-clicking (or command-clicking on the Mac) will pop up a menu of options such as cut/copy/paste, undo/redo, etc.

Definition at line 1061 of file juce_TextEditor.cpp.

◆ setReadOnly()

void juce::TextEditor::setReadOnly ( bool shouldBeReadOnly )

Changes the editor to read-only mode.

By default, the text editor is not read-only. If you're making it read-only, you might also want to call setCaretVisible (false) to get rid of the caret.

The text can still be highlighted and copied when in read-only mode.

See also: isReadOnly, setCaretVisible

Definition at line 1023 of file juce_TextEditor.cpp.

◆ setReturnKeyStartsNewLine()

void juce::TextEditor::setReturnKeyStartsNewLine ( bool shouldStartNewLine )

Changes the behaviour of the return key.

If set to true, the return key will insert a new-line into the text; if false it will trigger a call to the TextEditor::Listener::textEditorReturnKeyPressed() method. By default this is set to false, and when true it will only insert new-lines when in multi-line mode (see setMultiLine()).

Definition at line 1051 of file juce_TextEditor.cpp.

◆ setScrollbarsShown()

void juce::TextEditor::setScrollbarsShown ( bool shouldBeEnabled )

Enables or disables scrollbars (this only applies when in multi-line mode).

When the text gets too long to fit in the component, a scrollbar can appear to allow it to be scrolled. Even when this is enabled, the scrollbar will be hidden unless it's needed.

By default scrollbars are enabled.

Definition at line 1014 of file juce_TextEditor.cpp.

◆ setScrollBarThickness()

void juce::TextEditor::setScrollBarThickness ( int newThicknessPixels )

Changes the size of the scrollbars that are used.

Handy if you need smaller scrollbars for a small text box.

Definition at line 1219 of file juce_TextEditor.cpp.

◆ setScrollToShowCursor()

void juce::TextEditor::setScrollToShowCursor ( bool shouldScrollToShowCaret )

Used to disable the auto-scrolling which keeps the caret visible.

If true (the default), the editor will scroll when the caret moves offscreen. If set to false, it won't.

Definition at line 1545 of file juce_TextEditor.cpp.

◆ setSelectAllWhenFocused()

void juce::TextEditor::setSelectAllWhenFocused ( bool shouldSelectAll )

If set to true, focusing on the editor will highlight all its text.

(Set to false by default).

This is useful for boxes where you expect the user to re-enter all the text when they focus on the component, rather than editing what's already there.

Definition at line 1066 of file juce_TextEditor.cpp.

◆ setTabKeyUsedAsCharacter()

void juce::TextEditor::setTabKeyUsedAsCharacter ( bool shouldTabKeyBeUsed )

Indicates whether the tab key should be accepted and used to input a tab character, or whether it gets ignored.

By default the tab key is ignored, so that it can be used to switch keyboard focus between components.

Definition at line 1056 of file juce_TextEditor.cpp.

◆ setTemporaryUnderlining()

void juce::TextEditor::setTemporaryUnderlining ( const Array< Range< int > > & underlinedRegions )

overridevirtual

Sets a number of temporarily underlined sections.

This is needed by MS Windows input method UI.

Implements juce::TextInputTarget.

Definition at line 2302 of file juce_TextEditor.cpp.

◆ setText()

void juce::TextEditor::setText	(	const String &	newText,
		bool	sendTextChangeMessage = `true`
	)

Sets the entire content of the editor.

This will clear the editor and insert the given text (using the current text colour and font). You can set the current text colour using

setColour (TextEditor::textColourId, ...);

juce::Component::setColour

void setColour(int colourID, Colour newColour)

Registers a colour to be used for a particular purpose.

Definition juce_Component.cpp:1901

juce::TextEditor::textColourId

@ textColourId

The colour that will be used when text is added to the editor.

Definition juce_TextEditor.h:212

Parameters

newText	the text to add
sendTextChangeMessage	if true, this will cause a change message to be sent to all the listeners.

See also: insertTextAtCaret

Definition at line 1233 of file juce_TextEditor.cpp.

◆ setTextToShowWhenEmpty()

void juce::TextEditor::setTextToShowWhenEmpty	(	const String &	text,
		Colour	colourToUse
	)

When the text editor is empty, it can be set to display a message.

This is handy for things like telling the user what to type in the box - the string is only displayed, it's not taken to actually be the contents of the editor.

Definition at line 1204 of file juce_TextEditor.cpp.

◆ setWhitespaceUnderlined()

void juce::TextEditor::setWhitespaceUnderlined ( bool shouldUnderlineWhitespace )

noexcept

Sets whether whitespace should be underlined when the editor font is underlined.
