Struct gdk4::DeleteEvent[][src]

pub struct DeleteEvent(_);
Expand description

An event related to closing a top-level surface.

Implementations

Methods from Deref<Target = Event>

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

axis_use

the axis use to look for

Returns

true if the specified axis was found, otherwise false

value

location to store the value found

Returns the device of an event.

Returns

a Device

Retrieves the display associated to the self.

Returns

a Display

Retrieves the type of the event.

Returns

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.

Returns

an array of time and coordinates

Returns the modifier state field of an event.

Returns

the modifier state of self

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

Emulated pointer events typically originate from a touch events.

Returns

true if this event is emulated

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

Returns
x

location to put event surface x coordinate

y

location to put event surface y coordinate

Returns the seat that originated the event.

Returns

a Seat.

Extracts the surface associated with an event.

Returns

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.

Returns

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.

Returns

true if the event should trigger a context menu.
