|
||
* A #GdkEvent contains a union of all of the event types,
|
||
* and allows access to the data fields in a number of ways.
|
||
*
|
||
* The event type is always the first field in all of the event types, and
|
||
* can always be accessed with the following code, no matter what type of
|
||
* event it is:
|
||
* |[<!-- language="C" -->
|
||
* GdkEvent *event;
|
||
* GdkEventType type;
|
||
*
|
||
* type = event->type;
|
||
* ]|
|
||
*
|
||
* To access other fields of the event, the pointer to the event
|
||
* can be cast to the appropriate event type, or the union member
|
||
* name can be used. For example if the event type is %GDK_BUTTON_PRESS
|
||
* then the x coordinate of the button press can be accessed with:
|
||
* |[<!-- language="C" -->
|
||
* GdkEvent *event;
|
||
* gdouble x;
|
||
*
|
||
* x = ((GdkEventButton*)event)->x;
|
||
* ]|
|
||
* or:
|
||
* |[<!-- language="C" -->
|
||
* GdkEvent *event;
|
||
* gdouble x;
|
||
*
|
||
* x = event->button.x;
|
||
* ]|
