bool qdesigner_internal::SimplifyLayoutCommand::init ( QWidget * layoutBase)

Definition at line 899 of file qdesigner_command.cpp.

◆ redo()

void qdesigner_internal::SimplifyLayoutCommand::redo ( )
overridevirtual

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 function leads to undefined beahavior.

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

undo()

Reimplemented from qdesigner_internal::QDesignerFormWindowCommand.

Definition at line 912 of file qdesigner_command.cpp.

◆ undo()

void qdesigner_internal::SimplifyLayoutCommand::undo ( )
overridevirtual

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 function leads to undefined beahavior.

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