Constructor & Destructor Documentation

◆ DeleteAction()

juce::CodeDocument::DeleteAction::DeleteAction ( CodeDocument &  doc,
int  start,
int  end 
)
noexcept

Definition at line 972 of file juce_CodeDocument.cpp.

Member Function Documentation

◆ getSizeInUnits()

int juce::CodeDocument::DeleteAction::getSizeInUnits ( )
overridevirtual

Returns a value to indicate how much memory this object takes up.

Because the UndoManager keeps a list of UndoableActions, this is used to work out how much space each one will take up, so that the UndoManager can work out how many to keep.

The default value returned here is 10 - units are arbitrary and don't have to be accurate.

See also
UndoManager::getNumberOfUnitsTakenUpByStoredCommands, UndoManager::setMaxNumberOfStoredUnits

Reimplemented from juce::UndoableAction.

Definition at line 993 of file juce_CodeDocument.cpp.

◆ perform()

bool juce::CodeDocument::DeleteAction::perform ( )
overridevirtual

Overridden by a subclass to perform the action.

This method is called by the UndoManager, and shouldn't be used directly by applications.

Be careful not to make any calls in a perform() method that could call recursively back into the UndoManager::perform() method

Returns
true if the action could be performed.

UndoManager::perform

Implements juce::UndoableAction.

Definition at line 979 of file juce_CodeDocument.cpp.

◆ undo()

bool juce::CodeDocument::DeleteAction::undo ( )
overridevirtual

Overridden by a subclass to undo the action.

This method is called by the UndoManager, and shouldn't be used directly by applications.

Be careful not to make any calls in an undo() method that could call recursively back into the UndoManager::perform() method

Returns
true if the action could be undone without any errors.
