Field Documentation

◆ [union]

union { ... } gp_widget_event

A payload.

◆ bbox

struct gp_bbox* gp_widget_event::bbox

Optional bounding box.

The bounding box is passed in the case of a pixmap widget repaint event.

Definition at line 175 of file gp_widget_event.h.

◆ input_ev

struct gp_event* gp_widget_event::input_ev

An input event.

Points to an input event when gp_widget_event::type is set to GP_WIDGET_EVENT_INPUT. If a widget wants to process input events these have to be unmasked first by gp_widget_events_unmask().

Definition at line 184 of file gp_widget_event.h.

◆ sub_type

uint16_t gp_widget_event::sub_type

Widget specific subtype defined by widgets.

For all widget specific events the gp_widget_event::type is set to GP_WIDGET_EVENT_WIDGET and the gp_widget_event::sub_type is documented for each particular widget, e.g. gp_widget_tbox_event_type.

Definition at line 150 of file gp_widget_event.h.

◆ val

long gp_widget_event::val

Optional integer value.

This is used by widgets to pass an integer value, e.g. by a tbox widget to send an unicode characters for gp_widget_event::sub_type set to GP_WIDGET_EVENT_TBOX_PRE_FILTER from gp_widget_tbox_event_type.
