Panel Components are a sub-Family of Components, used to create custom interactive 2D control panels and user interfaces (also called Panels). They are found in the second column of Components in the OP Create dialog.
Examples are in Help > OP Snippets
The panel components are:
Container COMP - holds any number of other buttons, sliders, fields, containers, etc
Text COMP - for entering text strings and rendering text in Panels.
Slider COMP - simple sliders in X, Y and XY, and outputs 1 or 2 channels
Button COMP - simple on/off buttons, including toggle, momentary, and sets of radio buttons
List COMP - lets you create and define lists using python
OP Viewer COMP - creates a panel out of any operator's viewer
Parameter COMP - creates a panel out of any operator's parameters
Select COMP - selects a Panel Component from any other location
Table COMP - a concise and optimized way to create a grid of user interface gadgets
Panels within Panels
In 2D control panels, a Panel component is displayed within another panel (Parenting) in two possible ways:
- by placing the panel inside another Panel component (normally a Container component).
- by a node being attached to another node in the same network like in 3D Parenting.
