GimpToolWidgetGroup is a tool widget acting as a container for child widgets, multiplexing widget events and demultiplexing tool events. It can be used by tools to display multiple widgets simultaneously. The group keeps track of the current focus widget, and hover widget. Certain events are only dispatched to/forwarded from these widgets. The hover widget is determined by performing a hit test for all the children, starting from the last child. The first widget returning GIMP_HIT_DIRECT, if any, is selected as the hover widget; otherwise, if the current focus widget returns GIMP_HIT_INDIRECT, it's selected; otherwise, if exactly one widget returns GIMP_HIT_INDIRECT, it's selected; otherwise, there is no hover widget. The focus widget is set when clicking on a widget (or programatically, using gimp_tool_widget_set_focus()). Additionally, the group can raise the clicked widget to the top of the stack (see gimp_tool_widget_group_set_auto_raise().)
