Set one resource for a widget
#define PtSetResource( widget, type, value, len ) …
ph
This function sets a resource for the specified widget.
The type argument contains the
resource manifest and value contains
the value of the argument being passed. The
way the len argument is used depends on the resource type.
For information on getting and setting resources, see the
Manipulating Resources
in Application Code chapter
of the Photon Programmer's Guide.
If the widget has been realized, changing its resources
may change how it appears on the screen.
- 0
- The given resources was applied to the widget.
- -1
- The widget wasn't modified because it doesn't contain the given
resource or the value of the resource was the same as that
already stored in the widget.
Turn the widget blue:
PtWidget_t *widget;
PtSetResource( widget, Pt_ARG_FILL_COLOR, Pg_BLUE, 0 );
