Member Function Documentation

Merge()

virtual bool vtkUndoElement::Merge ( vtkUndoElement *  vtkNotUsednew_element )

inlinevirtual

Called on the older element in the UndoSet to merge with the element being added if both the elements are mergeable. Returns if the merge was successful. Default implementation doesn't do anything.

Definition at line 49 of file vtkUndoElement.h.

Referenced by vtkUndoSet::AddElement().

PrintSelf()

void vtkUndoElement::PrintSelf ( ostream &  os, vtkIndent  indent  )

override

Definition at line 31 of file vtkUndoElement.cxx.

References QtCompat::endl(), and Mergeable.

Redo()

virtual int vtkUndoElement::Redo ( )

pure virtual

Redo the operation encaspsulated by this element.

Returns

the status of the operation, 1 on success, 0 otherwise.

Referenced by vtkUndoSet::Redo(), and vtkUndoSet::Undo().

SetUndoSetWorkingContext()

virtual void vtkUndoElement::SetUndoSetWorkingContext ( vtkCollection *  workCTX )

inlinevirtual

Definition at line 60 of file vtkUndoElement.h.

Referenced by vtkUndoSet::Redo(), and vtkUndoSet::Undo().

Undo()

virtual int vtkUndoElement::Undo ( )

pure virtual

Undo the operation encapsulated by this element.

Returns

the status of the operation, 1 on success, 0 otherwise.

Referenced by vtkUndoSet::Redo(), and vtkUndoSet::Undo().

vtkGetMacro()

vtkUndoElement::vtkGetMacro	(	Mergeable	,
		bool
	)

Returns if this undo element can be merged with other undo elements. When an undo element is added to a vtkUndoSet unsing AddElement, an attempt is made to "merge" the element with the most recently added undo element, if any, if both the undo elements are mergeable.

vtkSetMacro()

Member Data Documentation

Mergeable

bool vtkUndoElement::Mergeable

protected

Subclasses must set this flag to enable merging of consecutive elements in an UndoSet.
