virtual void CEGUI::DragContainer::onAlphaChanged ( WindowEventArgs e)
protectedvirtual

Handler called when the window's alpha blend value is changed.

Parameters
eWindowEventArgs object whose 'window' pointer field is set to the window that triggered the event. For this event the trigger window is always 'this'.

Reimplemented from CEGUI::Window.

virtual void CEGUI::DragContainer::onCaptureLost ( WindowEventArgs e)
protectedvirtual

Handler called when this window loses capture of mouse inputs.

Parameters
eWindowEventArgs object whose 'window' pointer field is set to the window that triggered the event. For this event the trigger window is always 'this'.

Reimplemented from CEGUI::Window.

virtual void CEGUI::DragContainer::onClippingChanged ( WindowEventArgs e)
protectedvirtual

Handler called when the window's setting for being clipped by it's parent is changed.

Parameters
eWindowEventArgs object whose 'window' pointer field is set to the window that triggered the event. For this event the trigger window is always 'this'.
