Detailed Description

An abstract base class which can be implemented by components that function as text editors.

This class allows different types of text editor component to provide a uniform interface, which can be used by things like OS-specific input methods, on-screen keyboards, etc.

◆ VirtualKeyboardType

A set of possible on-screen keyboard types, for use in the getKeyboardType() method.

Definition at line 103 of file juce_TextInputTarget.h.

Member Function Documentation

◆ getCaretPosition()

virtual int juce::TextInputTarget::getCaretPosition ( ) const
pure virtual

Returns the current index of the caret.

Implemented in juce::TextEditor, and juce::CodeEditorComponent.

◆ getCaretRectangle()

Rectangle< int > juce::TextInputTarget::getCaretRectangle ( ) const

Returns the position of the caret, relative to the component's origin.

Definition at line 77 of file juce_TextInputTarget.h.

◆ getCaretRectangleForCharIndex()

virtual Rectangle< int > juce::TextInputTarget::getCaretRectangleForCharIndex ( int  characterIndex) const
pure virtual

Returns the bounding box of the character at the given index.

Implemented in juce::TextEditor, and juce::CodeEditorComponent.

◆ getCharIndexForPoint()

virtual int juce::TextInputTarget::getCharIndexForPoint ( Point< int point) const
pure virtual

Returns the index closest to the given point.

This is the location where the cursor might be placed after clicking at the given point in a text field.

Implemented in juce::TextEditor, and juce::CodeEditorComponent.

◆ getHighlightedRegion()

virtual Range< int > juce::TextInputTarget::getHighlightedRegion ( ) const
pure virtual

Returns the extents of the selected text region, or an empty range if nothing is selected,.

Implemented in juce::TextEditor, and juce::CodeEditorComponent.

◆ getKeyboardType()

virtual VirtualKeyboardType juce::TextInputTarget::getKeyboardType ( )
virtual

Returns the target's preference for the type of keyboard that would be most appropriate.

This may be ignored, depending on the capabilities of the OS.

Reimplemented in juce::TextEditor.

Definition at line 117 of file juce_TextInputTarget.h.

◆ getTextBounds()

virtual RectangleList< int > juce::TextInputTarget::getTextBounds ( Range< int textRange) const
pure virtual

Returns the bounding box for a range of text in the editor.

As the range may span multiple lines, this method returns a RectangleList.

The bounds are relative to the component's top-left and may extend beyond the bounds of the component if the text is long and word wrapping is disabled.

Implemented in juce::TextEditor, and juce::CodeEditorComponent.

◆ getTextInRange()

virtual String juce::TextInputTarget::getTextInRange ( const Range< int > &  range) const
pure virtual

Returns a specified sub-section of the text.

Implemented in juce::CodeEditorComponent, and juce::TextEditor.

◆ getTotalNumChars()

virtual int juce::TextInputTarget::getTotalNumChars ( ) const
pure virtual

Returns the total number of codepoints in the string.

Implemented in juce::TextEditor, and juce::CodeEditorComponent.

◆ insertTextAtCaret()

virtual void juce::TextInputTarget::insertTextAtCaret ( const String textToInsert)
pure virtual

Inserts some text, overwriting the selected text region, if there is one.

Implemented in juce::TextEditor, and juce::CodeEditorComponent.

◆ isTextInputActive()

virtual bool juce::TextInputTarget::isTextInputActive ( ) const
pure virtual

Returns true if this input target is currently accepting input.

For example, a text editor might return false if it's in read-only mode.

Implemented in juce::TextEditor, and juce::CodeEditorComponent.

◆ setHighlightedRegion()

virtual void juce::TextInputTarget::setHighlightedRegion ( const Range< int > &  newRange)
pure virtual

Sets the currently-selected text region.

Implemented in juce::CodeEditorComponent, and juce::TextEditor.

◆ setTemporaryUnderlining()

virtual void juce::TextInputTarget::setTemporaryUnderlining ( const Array< Range< int > > &  underlinedRegions)
pure virtual

Sets a number of temporarily underlined sections.

This is needed by MS Windows input method UI.

Implemented in juce::TextEditor, and juce::CodeEditorComponent.
