xs2qpa
Is specified panel active?
Prototype
int xs2qpa(int panelid);
Description
Is the specified panel active? Activity of a panel is modified using xs2tp. In dynamic mode, the callback is disabled if the panel is inactive.
See Also
| xs2cp | Select a panel for subsequent geometry calls. | |
| xs2ap | Add a new panel. | |
| xs2mp | Modify location of existing panel. | |
| xs2tp | Toggle visibility of panel. | |
| xs2lpc | Link panel cameras together. | |
| xs2qsp | Query currently selected panel. | |
| xs2qcpa | Is currently selected panel active? |
