[Gambas-bugtracker] Bug #2886: wayland and Mouse.ScreenX & Y, Top-level?


Comment #3 by Benoît MINISINI:

Mostly yes.

Not always useless, as the GUI toolkits normally returns in Mouse.ScreenX and Mouse.ScreenY the coordinates of the mouse cursor relative to the (activated?) window.

> And there is no way to get main form/window positions correctly?

No. All top-level windows are seen at coordinates 0,0.

The only exception in Wayland are sub-surfaces, i.e. windows that are told Wayland to be children of another windows. In that case, the sub-window has coordinates relative to its parent. They added that so that implementing popup windows becomes possible.

Benoît MINISINI changed the state of the bug to: Upstream.
