GUI (control panel) editor

When you open a GUI / control panel .pxr file it will open in the GUI editor. If the GUI was open (running), the external window will be closed and the panel “hijacked” into the editor. The control panel is still fully functional inside the editor.

To make changes to the control panel you need to enable the edit overlay. Toggle the Edit button in the editor toolbar (or use CTRL-E). Component boundaries will now highlight as you hover over them and you can select component by clicking on them. Switch off the edit overlay (using the same button / keys) to re-enable use of the control panel.

Add components to the control panel by dragging them from the palette (the edit overlay must be enabled). You can insert components by dropping them on top of existing components. Unlike the graph editor, the GUI editor gives all components an automatic name.

Edit component properties by double-clicking on them to open the component editor window, or selecting them and using the Properties tab. The GUI editor does not currently support multiple select.

Components are organised in a grid / table. You can move selected components around the panel by using the arrow buttons in the editor toolbar or the arrow keys on the keyboard. It is possible for components to span multiple rows or columns of the grid, using the buttons in the toolbar or holding CTRL while using the arrow keys.

To bind a GUI component to a property of another component, use the .binding property - you may enter a control address manually or use the address browser (ellipsis button) to search through existing components. GUI components will attempt to configure themselves from the binding – eg. a slider with no minimum / maximum value overrides will use the minimum / maximum values of the bound control. When bound to a property control, GUI components will automatically sync.

Remove components by selecting them and using the Delete key or the delete button on the editor toolbar.
