Referenced by qdesigner_internal::FormWindowManager::slotActionAdjustSizeActivated().

Here is the call graph for this function:

void qdesigner_internal::AdjustWidgetSizeCommand::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.

undo()

Reimplemented from qdesigner_internal::QDesignerFormWindowCommand.

Definition at line 2004 of file qdesigner_command.cpp.

References QWidget::adjustSize(), qdesigner_internal::QDesignerFormWindowCommand::core(), qdesigner_internal::QDesignerFormWindowCommand::formWindow(), QWidget::geometry(), qdesigner_internal::Utils::isCentralWidget(), m_geometry, m_widget, QWidget::parentWidget(), and QCoreApplication::processEvents().

{
    QWidget *widget = m_widget;
    if (Utils::isCentralWidget(formWindow(), widget) && formWindow()->parentWidget())
        widget = formWindow()->parentWidget();

    m_geometry = widget->geometry();

    }

    if (QDesignerPropertyEditorInterface *propertyEditor = formWindow()->core()->propertyEditor()) {
        if (propertyEditor->object() == m_widget)
            propertyEditor->setPropertyValue(QLatin1String("geometry"), m_widget->geometry(), true);
    }
}

Here is the call graph for this function:

void qdesigner_internal::AdjustWidgetSizeCommand::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.
