Detailed Description

TUI-specific widget base class.

Thin subclass of the core Widget that adds TUI-specific behavior: notifying TuiSubsystem when the widget is dirty so that the screen can be repainted.

All geometry, visibility, focus, size policy, layout, and event dispatch functionality is inherited from Widget.

Thread Safety

Thread-affine via ObjectBase. All TUI widgets must be created and accessed from the thread that owns the TUI EventLoop (typically the thread that drives TuiSubsystem). Cross-thread interaction is supported only through ObjectBase signal/slot dispatch.
