Detailed Description

A button.

A button with a label and/or icon, which may be standalone, or be added to a ToolBar (see ToolBar::addButton()) or to a Dialog (see Dialog::addButton()).

The API is similar to the WPushButton API, with the following additional features:

an icon may be specified using AbstractButton::setIcon();
the button may be configured as a toggle button (see AbstractButton::setCheckable();
the button may be associated with a popup-menu (see AbstractButton::setMenu();
