Expand description

Defines the methods implemented by all group widgets

Required methods

Begins a group, used for widgets implementing the group trait

Ends a group, used for widgets implementing the group trait

Clear a group from all widgets

Clear a group from all widgets using FLTK’s clear call.

Safety

Ignores widget tracking

Return the number of children in a group

Return child widget by index

Find a widget within a group and return its index

Add a widget to a group

Insert a widget to a group at a certain index

Remove a widget from a group, but does not delete it

Remove a child widget by its index

Make the passed widget resizable

Make the window resizable, should be called before show

Clips children outside the group boundaries

Get whether clip_children is set

Draw a child widget, the call should be in a WidgetBase::draw method

Update a child widget, the call should be in a WidgetBase::draw method

Draw the outside label, the call should be in a WidgetBase::draw method

Draw children, the call should be in a WidgetBase::draw method
