Enum StyleAppRegion 

#[repr(C)]
pub enum StyleAppRegion {
    NoDrag = 0,
    Drag = 1,
}

Whether dragging this element moves the WINDOW — azul’s app-region.

Modelled on Electron’s -webkit-app-region, and accepted under both -azul-app-region and -webkit-app-region so existing CSS ports over unchanged.

.titlebar        { -azul-app-region: drag; }
.titlebar button { -azul-app-region: no-drag; }

This is what lets an application turn window decorations off and draw its own title bar without losing what a native one does: drag to move, double-click to maximize.

It does NOT cascade. A drag region names the exact element that is draggable, and inheriting it would make every button, label and icon inside a title bar drag the window instead of doing its own job — which is the bug no-drag exists to undo in Electron. Here the default simply never propagates, so children opt IN rather than out.

Variants

NoDrag = 0

Normal content: the element handles its own input.

Drag = 1

Dragging this element moves the window; double-clicking it toggles maximize/restore.
