Implementations§
source§impl X11Surface
impl X11Surface
sourcepub fn move_to_current_desktop(&self)
pub fn move_to_current_desktop(&self)
Moves the surface to the correct workspace when running under a window manager that supports multiple workspaces, as described in the Extended Window Manager Hints specification. Will not do anything if the surface is already on all workspaces.
sourcepub fn move_to_desktop(&self, desktop: u32)
pub fn move_to_desktop(&self, desktop: u32)
Moves the surface to the given workspace when running unde a window manager that supports multiple workspaces, as described in the Extended Window Manager Hints specification.
desktop
the number of the workspace to move the surface to
sourcepub fn set_frame_sync_enabled(&self, frame_sync_enabled: bool)
pub fn set_frame_sync_enabled(&self, frame_sync_enabled: bool)
This function can be used to disable frame synchronization for a surface. Normally frame synchronziation will be enabled or disabled based on whether the system has a compositor that supports frame synchronization, but if the surface is not directly managed by the window manager, then frame synchronziation may need to be disabled. This is the case for a surface embedded via the XEMBED protocol.
frame_sync_enabled
whether frame-synchronization should be enabled
sourcepub fn set_skip_pager_hint(&self, skips_pager: bool)
pub fn set_skip_pager_hint(&self, skips_pager: bool)
Sets a hint on @self that pagers should not display it. See the EWMH for details.
skips_pager
true to skip pagers
sourcepub fn set_skip_taskbar_hint(&self, skips_taskbar: bool)
pub fn set_skip_taskbar_hint(&self, skips_taskbar: bool)
Sets a hint on @self that taskbars should not display it. See the EWMH for details.
skips_taskbar
true to skip taskbars
sourcepub fn set_theme_variant(&self, variant: &str)
pub fn set_theme_variant(&self, variant: &str)
GTK applications can request a dark theme variant. In order to make other applications - namely window managers using GTK for themeing - aware of this choice, GTK uses this function to export the requested theme variant as _GTK_THEME_VARIANT property on toplevel surfaces.
Note that this property is automatically updated by GTK, so this function should only be used by applications which do not use GTK to create toplevel surfaces.
variant
the theme variant to export
sourcepub fn set_urgency_hint(&self, urgent: bool)
pub fn set_urgency_hint(&self, urgent: bool)
sourcepub fn set_user_time(&self, timestamp: u32)
pub fn set_user_time(&self, timestamp: u32)
The application can use this call to update the _NET_WM_USER_TIME property on a toplevel surface. This property stores an Xserver time which represents the time of the last user input event received for this surface. This property may be used by the window manager to alter the focus, stacking, and/or placement behavior of surfaces when they are mapped depending on whether the new surface was created by a user action or is a “pop-up” surface activated by a timer or some other event.
Note that this property is automatically updated by GDK, so this function should only be used by applications which handle input events bypassing GDK.
timestamp
An XServer timestamp to which the property should be set
sourcepub fn set_utf8_property(&self, name: &str, value: Option<&str>)
pub fn set_utf8_property(&self, name: &str, value: Option<&str>)

sourcepub fn xid(&self) -> XWindow
pub fn xid(&self) -> XWindow

window: XWindow
) -> Option<X11Surface>
pub fn lookup_for_display(
display: &X11Display,
window: XWindow
) -> Option<X11Surface>
Looks up the gdk::Surface that wraps the given native window handle.
display
the gdk::Display corresponding to the
window handle
window
an Xlib Window
Returns
the gdk::Surface wrapper
for the native window
