Member Function Documentation

void QtGui.IQUndoStackSignals.CanRedoChanged ( bool  canRedo)

This signal is emitted whenever the value of canRedo() changes. It is used to enable or disable the redo action returned by createRedoAction(). canRedo specifies the new value.

void QtGui.IQUndoStackSignals.CanUndoChanged ( bool  canUndo)

This signal is emitted whenever the value of canUndo() changes. It is used to enable or disable the undo action returned by createUndoAction(). canUndo specifies the new value.

void QtGui.IQUndoStackSignals.CleanChanged ( bool  clean)

This signal is emitted whenever the stack enters or leaves the clean state. If clean is true, the stack is in a clean state; otherwise this signal indicates that it has left the clean state.

See also isClean() and setClean().

void QtGui.IQUndoStackSignals.IndexChanged ( int  idx)

This signal is emitted whenever a command modifies the state of the document. This happens when a command is undone or redone. When a macro command is undone or redone, or setIndex() is called, this signal is emitted only once.

idx specifies the index of the current command, ie. the command which will be executed on the next call to redo().

See also index() and setIndex().

void QtGui.IQUndoStackSignals.RedoTextChanged ( string  redoText)

This signal is emitted whenever the value of redoText() changes. It is used to update the text property of the redo action returned by createRedoAction(). redoText specifies the new text.

void QtGui.IQUndoStackSignals.UndoTextChanged ( string  undoText)

This signal is emitted whenever the value of undoText() changes. It is used to update the text property of the undo action returned by createUndoAction(). undoText specifies the new text.
