c - Starting with gdk_default_root_window -> Get all monitors -

-

i writing function x, y, width, , height of monitors of multi moniotr setup.

i found solution: https://stackoverflow.com/a/23608025/5062337

so implemented jsctypes:

            var collmoninfos = [];              var rootgdkwin = ostypes.api('gdk_get_default_root_window')();             console.info('rootgdkwin:', rootgdkwin.tostring(), uneval(rootgdkwin), cutils.jscgetdeepest(rootgdkwin));              var rootgtkwin = ostypes.helper.gdkwinptrtogtkwinptr(rootgdkwin);              // screen contains monitors             var gdkscreen = ostypes.api('gtk_window_get_screen')(rootgtkwin);              var fullwidth = ostypes.api('gdk_screen_get_width')(gdkscreen);             var fullheight = ostypes.api('gdk_screen_get_height')(gdkscreen);              console.info('fullwidth:', fullwidth.tostring(), 'fullheight:', fullheight.tostring());              // collect data each monitor             var monitors = [];             var nmons = ostypes.api('gdk_screen_get_n_monitors')(gdkscreen);             console.info('number of monitors:', nmons);             nmons = cutils.jscgetdeepest(nmons);              var rect = ostypes.type.gdkrectangle();             (var i=0; i<nmons; i++) {                 var mg = ostypes.api('gdk_screen_get_monitor_geometry')(gdkscreen, i, rect.address());                 collmoninfos.push({                     x: cutils.jscgetdeepest(rect.x),                     y: cutils.jscgetdeepest(rect.y),                     w: cutils.jscgetdeepest(rect.width),                     h: cutils.jscgetdeepest(rect.height)                 })             }              return collmoninfos;

however tells me have 0 monitors.

so wondering, starting gdk_default_root_window, how info on monitors?

i know can union of monitors gdk_drawable_get_size need individual monitor information please.

thanks
