Here is the call graph for this function:

void qdesigner_internal::InsertWidgetCommand::redo

(

)

[virtual]

Applies a change to the document. This function must be implemented in the derived class. Calling QUndoStack::push(), QUndoStack::undo() or QUndoStack::redo() from this funciton leads to undefined beahavior.

The default implementation calls redo() on all child commands.

Here is the call graph for this function:

void qdesigner_internal::InsertWidgetCommand::undo

(

)

[virtual]

Reverts a change to the document. After undo() is called, the state of the document should be the same as before redo() was called. This function must be implemented in the derived class. Calling QUndoStack::push(), QUndoStack::undo() or QUndoStack::redo() from this funciton leads to undefined beahavior.

The default implementation calls undo() on all child commands in reverse order.
