Expand description

Specifies the type of the event.

Do not confuse these events with the signals that GTK+ widgets emit. Although many of these events result in corresponding signals being emitted, the events are often transformed or filtered along the way.

In some language bindings, the values [_2buttonPress][Self::_2buttonPress] and [_3buttonPress][Self::_3buttonPress] would translate into something syntactically invalid (eg Gdk.EventType.2ButtonPress, where a symbol is not allowed to start with a number). In that case, the aliases DoubleButtonPress and TripleButtonPress can be used instead.

Variants (Non-exhaustive)

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Destroy

the window has been destroyed.

Expose

all or part of the window has become visible and needs to be redrawn.

MotionNotify

the pointer (usually a mouse) has moved.

ButtonPress

a mouse button has been pressed.

DoubleButtonPress

alias for [_2buttonPress][Self::_2buttonPress], added in 3.6.

TripleButtonPress

alias for [_3buttonPress][Self::_3buttonPress], added in 3.6.

ButtonRelease

a mouse button has been released.

KeyPress

a key has been pressed.

KeyRelease

a key has been released.

EnterNotify

the pointer has entered the window.

LeaveNotify

the pointer has left the window.

FocusChange

the keyboard focus has entered or left the window.

ProximityOut

an input device has moved out of contact with a sensing surface.

DragEnter

the mouse has entered the window while a drag is in progress.

DragLeave

the mouse has left the window while a drag is in progress.

DragMotion

the mouse has moved in the window while a drag is in progress.

DropFinished

the drop operation initiated by the window has completed.

ClientEvent

a message has been received from another application.

VisibilityNotify

Scroll

the scroll wheel was turned

WindowState

the state of a window has changed. See WindowState for the possible window states
