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

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

The resizable widget defines both the resizing frame and the resizing behavior of the group and its children.

Make the group itself resizable, should be called before the widget is shown

Adds a widget to the group and makes it the resizable widget

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

Resets the internal array of widget sizes and positions

Get the bounds of all children widgets (left, upper, right, bottom)

Converts a widget implementing GroupExt into a Group widget

Safety

If the widget wasn’t created by fltk-rs, vtable differences mean certain methods can’t be overriden (e.g. handle & draw)
