Re: Gtk Window Screen Boundaries

[Daniel Saul <daniel saul gmail com>]

I was able to solve this problem.

Sample Code:

#import <gtk/gtk.h>
#import <gdk/gdk.h>
#import <gdk/gdkx.h>
#import <X11/Xlib.h>
#import <X11/Xatom.h>

+ (void)reserveLeftWidth:(guint32)leftWidth
			   leftStart:(guint32)leftStart
				 leftEnd:(guint32)leftEnd
			  rightWidth:(guint32)rightWidth
			  rightStart:(guint32)rightStart
				rightEnd:(guint32)rightEnd
			   topHeight:(guint32)topHeight
				topStart:(guint32)topStart
				  topEnd:(guint32)topEnd
			bottomHeight:(guint32)bottomHeight
			 bottomStart:(guint32)bottomStart
			   bottomEnd:(guint32)bottomEnd
				maWindow:(MAWindow *)maWindow
{
	static Atom net_wm_strut = 0;
	static Atom net_wm_strut_partial = 0;
	GtkWindow * gtkWindow = NULL;
	GdkWindow * gdkWindow = NULL;
	Display * display = NULL;
	Window window = 0;
	gulong struts[12];
	bzero(&struts,sizeof(struts));
	
	gtkWindow = GTK_WINDOW([maWindow widget]);
	assert(NULL != gtkWindow);
	
	gdkWindow = GTK_WIDGET(gtkWindow)->window;
	assert(NULL != gdkWindow);
	assert(GDK_IS_DRAWABLE(gdkWindow));
	assert(GDK_IS_WINDOW(gdkWindow));
	
	display = GDK_WINDOW_XDISPLAY(gdkWindow);
	window = GDK_WINDOW_XWINDOW(gdkWindow);
	
	if (net_wm_strut == 0) net_wm_strut = XInternAtom(display,  
"_NET_WM_STRUT", False);
	if (net_wm_strut_partial == 0) net_wm_strut_partial =  
XInternAtom(display, "_NET_WM_STRUT_PARTIAL", False);
	
	struts[kXStrutTop] = topHeight;
	struts[kXStrutTopStart] = topStart;
	struts[kXStrutTopEnd] = topEnd;
	
	struts[kXStrutBottom] = bottomHeight;
	struts[kXStrutBottomStart] = bottomStart;
	struts[kXStrutBottomEnd] = bottomEnd;
	
	struts[kXStrutLeft] = leftWidth;
	struts[kXStrutLeftStart] = leftStart;
	struts[kXStrutLeftEnd] = leftEnd;
	
	struts[kXStrutRight] = rightWidth;
	struts[kXStrutRightStart] = rightStart;
	struts[kXStrutRightEnd] = rightEnd;
	
	gdk_error_trap_push();
	{
		XChangeProperty(display, window, net_wm_strut, XA_CARDINAL, 32,  
PropModeReplace, (guchar *)&struts, 4);
		XChangeProperty (display, window, net_wm_strut_partial, XA_CARDINAL,  
32, PropModeReplace, (guchar *)&struts, 12);
	}
	gdk_error_trap_pop();
}
