Area for the widget. This is the area given to render(), corrected by the given constraints. read only. renewed for each render.

area_z: u16

Z-Index for the popup.

h_scroll: ScrollState

Horizontal scroll state if active. read+write

v_scroll: ScrollState

Vertical scroll state if active. read+write

active: FocusFlag

Active flag for the popup.

Uses a ContainerFlag that can be combined with the FocusFlags your widget uses for handling its focus to detect the transition ‘Did the popup loose focus and should it be closed now’.

If you don’t rely on Focus this way, this will just be a boolean flag that indicates active/visible.

See See the examples how to use for both cases. read+write

mouse: MouseFlags

non_exhaustive: NonExhaustive
