◆ clone()

Widget::Ptr tgui::ScrollablePanel::clone ( ) const

inlineoverrideprotectedvirtual

Makes a copy of the widget if you don't know its exact type.

This function should only be used when you don't know the type of the widget. If you know what kind of widget you are copying, you should use the copy function.

Returns: Copy of the widget

Reimplemented from tgui::Panel.

◆ copy()
