Some application may wish to restrict their window in size, but xdg-shell has no mechanism for the client to advertise such a maximum or minimum size the compositor can use.
As a result, the compositor may try to maximize or fullscreen a window while the client would not allow for the requested size. Add new requests "set_preferred_max_size" and "set_preferred_min_size" to xdg-shell so that the client can tell the compositor which would be its preferred smallest/largest acceptable size, so that he compositor can decide if maximize or fullscreen makes sense, draw an accurate animation, etc. Signed-off-by: Olivier Fourdan <ofour...@redhat.com> Bugzilla: https://bugzilla.gnome.org/show_bug.cgi?id=764413 --- v2: Rename the request to "set_preferred_max_size", add "set_preferred_min_size" as well unstable/xdg-shell/xdg-shell-unstable-v5.xml | 46 ++++++++++++++++++++++++++++ 1 file changed, 46 insertions(+) diff --git a/unstable/xdg-shell/xdg-shell-unstable-v5.xml b/unstable/xdg-shell/xdg-shell-unstable-v5.xml index 542491f..9c9b4d2 100644 --- a/unstable/xdg-shell/xdg-shell-unstable-v5.xml +++ b/unstable/xdg-shell/xdg-shell-unstable-v5.xml @@ -462,6 +462,52 @@ <arg name="height" type="int"/> </request> + <request name="set_preferred_max_size"> + <description summary="set the preferred maximum size"> + Set a preferred maximum size for the surface. + + The client can specify a maximum width and/or height to tell the + compositor what would be the preferred largest size for a surface. + + The compositor may use this information from the client to allow + or disallow different states like maximixe or fullscreen and + draw accurate animations. + Similarily, a tiling window manager can use this information to + place and resize client windows in a more effective layout. + + If never set, the size of the surface is not limited by the client. + + A value of zero for either width, height or both means that the + client has no preference regarding the maximum size in the given + dimension. + </description> + <arg name="width" type="int"/> + <arg name="height" type="int"/> + </request> + + <request name="set_preferred_min_size"> + <description summary="set the preferred minimum size"> + Set a preferred minimum size for the surface. + + The client can specify a minimum width and/or height to tell the + compositor what would be the preferable smallest size of a surface. + + The compositor may use this information from the client to allow + or disallow different states like maximixe or fullscreen and + draw accurate animations. + Similarily, a tiling window manager can use this information to + place and resize client windows in a more effective layout. + + If never set, the size of the surface is not limited by the client. + + A value of zero for either width, height or both means that the + client has no preference regarding the minimum size in the given + dimension. + </description> + <arg name="width" type="int"/> + <arg name="height" type="int"/> + </request> + <request name="set_maximized"> <description summary="maximize the window"> Maximize the surface. -- 2.5.5 _______________________________________________ wayland-devel mailing list wayland-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/wayland-devel
