Issue with initial window position

[PrasanthKumar P.A.]

Hi,
Thank you for your quick response.
These  are our concerns.
Our application is a HMI that is to be deployed on IMX8 board.
By design we need to place some  QT Qml windows on specified x y  coordinates on the screen  .How can we achieve this ?

Also I am interested on (If your target environment is not a desktop, then the design could be
different). Can you please comment on this.

Thanks,
Prasanth

Hi,

this is expected. Wayland on desktops has no official way to position
windows from the client by global or per-output x,y coordinates. This
is by design for desktops. On the desktop, the window manager is the
only one that knows enough to be able to position windows correctly.

Weston decides the initial window position by random. Other compositors
use other algorithms.

If your target environment is not a desktop, then the design could be
different.

Why do you want your client to position the window specifically by
coordinates?

How is it possible that your client can even pick sensible coordinates?

Why do you want your app to pick the initial position instead of the
window manager?


Thanks,
pq
