Struct gdk4::GrabBrokenEvent[][src]

pub struct GrabBrokenEvent(_);
Expand description

An event related to a broken windowing system grab.


Extracts the grab surface from a grab broken event.


the grab surface of @self

Checks whether the grab broken event is for an implicit grab.


true if the an implicit grab was broken

Methods from Deref<Target = Event>

Returns a DeviceTool representing the tool that caused the event.

If the was not generated by a device that supports different tools (such as a tablet), this function will return None.

Note: the DeviceTool will be constant during the application lifetime, if settings must be stored persistently across runs, see DeviceTool::serial().


The current device tool

Retuns the event sequence to which the event belongs.

Related touch events are connected in a sequence. Other events typically don’t have event sequence information.


the event sequence that the event belongs to

Extracts all axis values from an event.


true on success, otherwise false


the array of values for all axes

Extract the axis value for a particular axis use from an event structure.


the axis use to look for


true if the specified axis was found, otherwise false


location to store the value found

Returns the device of an event.


a Device

Retrieves the display associated to the @self.


a Display

Retrieves the type of the event.


a EventType

Retrieves the history of the device that @self is for, as a list of time and coordinates.

The history includes positions that are not delivered as separate events to the application because they occurred in the same frame as @self.

Note that only motion and scroll events record history, and motion events do it only if one of the mouse buttons is down.


an array of time and coordinates

Returns the modifier state field of an event.


the modifier state of @self

Returns whether this event is an ‘emulated’ pointer event.

Emulated pointer events typically originate from a touch events.


true if this event is emulated

Extract the event surface relative x/y coordinates from an event.


location to put event surface x coordinate


location to put event surface y coordinate

Returns the seat that originated the event.


a Seat.

Extracts the surface associated with an event.


The Surface associated with the event

Returns the timestamp of @self.

Not all events have timestamps. In that case, this function returns GDK_CURRENT_TIME.


timestamp field from @self

Returns whether a Event should trigger a context menu, according to platform conventions.

The right mouse button typically triggers context menus.

This function should always be used instead of simply checking for event->button == GDK_BUTTON_SECONDARY.


true if the event should trigger a context menu.
