class Panel

Extends:

ContainerComponent, UIComponent, ShapeContainer

Description:

Panel UI component, rectangular UI component that can be used in many different ways:

• Container for other components
• As a horizontal/vertical line or a rectangle
• Container with scroll bars that can contain objects even outside its boundaries.
• Background can be set to color, image, and gradient (like in CSS), which opens lots of opportunities, such as animating background, streaming MJPEG video by setting frames as background of the panel sequentially, and more.
• As a canvas to draw Shapes or create an interactive game using Shapes drawn on this canvas.

Panel class extends ContainerComponent and ShapeContainer, which extend UIComponent

NOTE: Add Panel to Tabs, SplitView, or ScrollPane containers before adding child components to the panel to have expected behavior when setting anchors to child components of the Panel.
