Struct gdk::EventButton
source · [−]pub struct EventButton(_);
Expand description
Used for button press and button release events. The
type
field will be one of EventType::ButtonPress
,
[EventType::_2buttonPress
][crate::EventType::_2buttonPress], [EventType::_3buttonPress
][crate::EventType::_3buttonPress] or EventType::ButtonRelease
,
Double and triple-clicks result in a sequence of events being received. For double-clicks the order of events will be:
EventType::ButtonPress
EventType::ButtonRelease
EventType::ButtonPress
- [
EventType::_2buttonPress
][crate::EventType::_2buttonPress] EventType::ButtonRelease
Note that the first click is received just like a normal
button press, while the second click results in a [EventType::_2buttonPress
][crate::EventType::_2buttonPress]
being received just after the EventType::ButtonPress
.
Triple-clicks are very similar to double-clicks, except that
[EventType::_3buttonPress
][crate::EventType::_3buttonPress] is inserted after the third click. The order of the
events is:
EventType::ButtonPress
EventType::ButtonRelease
EventType::ButtonPress
- [
EventType::_2buttonPress
][crate::EventType::_2buttonPress] EventType::ButtonRelease
EventType::ButtonPress
- [
EventType::_3buttonPress
][crate::EventType::_3buttonPress] EventType::ButtonRelease
For a double click to occur, the second button press must occur within 1/4 of a second of the first. For a triple click to occur, the third button press must also occur within 1/2 second of the first button press.
