Expand description
Describes an event from a Window
.
Variants
Resized(PhysicalSize<u32>)
Expand description
The size of the window has changed. Contains the client area’s new dimensions.
Moved(PhysicalPosition<i32>)
Expand description
The position of the window has changed. Contains the window’s new position.
Expand description
The window has been requested to close.
Expand description
The window has been destroyed.
DroppedFile(PathBuf)
Expand description
A file has been dropped into the window.
When the user drops multiple files at once, this event will be emitted for each file separately.
HoveredFile(PathBuf)
Expand description
A file is being hovered over the window.
When the user hovers multiple files at once, this event will be emitted for each file separately.
Expand description
A file was hovered, but has exited the window.
There will be a single HoveredFileCancelled
event triggered even if multiple files were
hovered.
ReceivedCharacter(char)
Expand description
The window received a unicode character.
Focused(bool)
Expand description
The window gained or lost focus.
The parameter is true if the window has gained focus, and false if it has lost focus.
Expand description
An event from the keyboard has been received.
Show fields
Fields of KeyboardInput
device_id: DeviceId
input: KeyboardInput
is_synthetic: bool
Expand description
If true
, the event was generated synthetically by tao
in one of the following circumstances:
- Synthetic key press events are generated for all keys pressed when a window gains focus. Likewise, synthetic key release events are generated for all keys pressed when a window goes out of focus. Currently, this is only functional on Linux and Windows
Otherwise, this value is always false
.
ModifiersChanged(ModifiersState)
Expand description
The keyboard modifiers have changed.
Expand description
The cursor has moved on the window.
Show fields
Fields of CursorMoved
device_id: DeviceId
position: PhysicalPosition<f64>
Expand description
(x,y) coords in pixels relative to the top-left corner of the window. Because the range of this data is limited by the display area and it may have been transformed by the OS to implement effects such as cursor acceleration, it should not be used to implement non-cursor-like interactions such as 3D camera control.
modifiers: ModifiersState
Deprecated in favor of WindowEvent::ModifiersChanged
Expand description
The cursor has entered the window.
Show fields
Fields of CursorEntered
device_id: DeviceId
Expand description
The cursor has left the window.
Show fields
Fields of CursorLeft
device_id: DeviceId
Expand description
A mouse wheel movement or touchpad scroll occurred.
Show fields
Fields of MouseWheel
device_id: DeviceId
delta: MouseScrollDelta
phase: TouchPhase
modifiers: ModifiersState
Deprecated in favor of WindowEvent::ModifiersChanged
Expand description
An mouse button press has been received.

Expand description
Touchpad pressure event.
At the moment, only supported on Apple forcetouch-capable macbooks. The parameters are: pressure level (value between 0 and 1 representing how hard the touchpad is being pressed) and stage (integer representing the click level).
Expand description
Motion on some analog axis. May report data redundant to other, more specific events.
Touch(Touch)
Expand description
Touch event has been received
Expand description
The window’s scale factor has changed.
The following user actions can cause DPI changes:
- Changing the display’s resolution.
- Changing the display’s scale factor (e.g. in Control Panel on Windows).
- Moving the window to a display with a different scale factor.
After this event callback has been processed, the window will be resized to whatever value
is pointed to by the new_inner_size
reference. By default, this will contain the size suggested
by the OS, but it can be changed to any value.
For more information about DPI in general, see the dpi
module.
Show fields
Fields of ScaleFactorChanged
scale_factor: f64
new_inner_size: &'a mut PhysicalSize<u32>
ThemeChanged(Theme)
Expand description
The system window theme has changed.
Applications might wish to react to this to change the theme of the content of the window when the system changes the window theme.
At the moment this is only supported on Windows.
