#[non_exhaustive]
pub enum Event<'a> {
    Configure {
        x: i32,

        width: i32,

Available on crate feature wayland and Linux only.

Variants (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.

Configure

configure the popup surface

This event asks the popup surface to configure itself given the configuration. The configured state should not be applied immediately. See xdg_surface.configure for details.

The x and y arguments represent the position the popup was placed at given the xdg_positioner rule, relative to the upper left corner of the window geometry of the parent surface.

For version 2 or older, the configure event for an xdg_popup is only ever sent once for the initial configuration. Starting with version 3, it may be sent again if the popup is setup with an xdg_positioner with set_reactive requested, or in response to xdg_popup.reposition requests.

Fields

x: i32

x position relative to parent surface window geometry

y: i32

y position relative to parent surface window geometry

width: i32

window geometry width

height: i32

window geometry height

PopupDone

popup interaction is done

The popup_done event is sent out when a popup is dismissed by the compositor. The client should destroy the xdg_popup object at this point.

Repositioned

signal the completion of a repositioned request

The repositioned event is sent as part of a popup configuration sequence, together with xdg_popup.configure and lastly xdg_surface.configure to notify the completion of a reposition request.

The repositioned event is to notify about the completion of a xdg_popup.reposition request. The token argument is the token passed in the xdg_popup.reposition request.

Immediately after this event is emitted, xdg_popup.configure and xdg_surface.configure will be sent with the updated size and position, as well as a new configure serial.

The client should optionally update the content of the popup, but must acknowledge the new popup configuration for the new position to take effect. See xdg_surface.ack_configure for details.

Only available since version 3 of the interface

Fields

token: u32

reposition request token
