Determine if a region is required
void PtCoreChangeRegion( unsigned int fields,
PtWidget_t *widget );
- fields
- A bitmap that indicates which attributes of the widget to check.
For more information, see
PhRegionOpen()
in the Photon Library Reference.
- widget
- A pointer to the widget to be tested.
This function examines the current state of widget with
respect to fields and determines if widget
requires a region. If a region is required,
PtCoreChangeRegion() determines what attributes
(e.g. sensitivity) are required.
PtCoreChangeRegion() may call one of the following
functions with appropriate attributes:
| If the widget: |
