Re: How does one get the screen coordinates of the workspace?

[Jim Charlton]

I use gtkmm and get screen size before opening the application window in 
order to make sure it fits on the display.  the equivalent gtk/gdk calls 
(I think)  use gtk_window_get_screen() to get the gdk window from 
the gtk window.  Then from the gdk window I use gdk_window_get_height() 
to get the height, and then gtk_window_resize() to resize the original 
gtk window to fit.


It has been a while since I looked at the code... but I think that was it.

Is there better way to do this?

Hello,

this makes me wonder why you need these coordinates?

If you want to set the window size to the maximum, then just maximize it.

If you want to move it around automatically, like put it on the center of
the screen, don't do that. There are situations, e.g. for users with
multiple monitors of diyzfferent sizes, when you do more harm than good
with this approach.

Best,
Gergely

I can remember that exactly that was a minimal example for my Nim GDK3
bindings. See

Thanks for the suggestions, the GDK call that works follows, but I 
should of gave more background. My app is a suggester window which 
follows the cursor of different app, a text editor.  So I need to know 
the workspace boundaries to figure out were I have space around the 
editor's cursor to present the suggester window. An obvious situation is 
when the editor's cursor gets to the bottom of the screen the suggester 
will have to float along above it. All this is in C and uses shared 
memory for communication between the apps.


GdkRectangle workSpace;
gdk_screen_get_monitor_workarea(gdk_screen_get_default(), 0, 
);
