Struct unsegen::widget::widget::WithDemand[−][src]

pub struct WithDemand<W, F>(_, _);
Expand description

Alter the reported demand of the widget. This can be useful, for example, to force a widget to assume all space in the window or to artificially restrict the size of a widget.

This wrapper can be created using WidgetExt::centered.
