nanogui: Thread: GrMoveWindow and NanoWM

Hi all,

I'm using nano-X, nanowm and a little application 
creating a window which should move its 
window position after a click into the window.

This is just a little demo, of what I want:

=========================================================

#define MWINCLUDECOLORS
#include <stdio.h>
#include "nano-X.h"

int main(int ac,char **av)
{
    GR_WINDOW_ID w;
    GR_GC_ID gc;
    GR_EVENT event;
    GR_COORD x = 20;

    if (GrOpen() < 0) {
        printf("Can't open graphics\n");
        exit(1);
    }

    w = GrNewWindow(GR_ROOT_WINDOW_ID, x, 20, 100, 60,
        0, WHITE, BLUE);
    gc = GrNewGC();
    GrSetGCForeground(gc, BLACK);
    GrSetGCUseBackground(gc, GR_FALSE);

    GrSelectEvents(w, GR_EVENT_MASK_EXPOSURE |
GR_EVENT_MASK_BUTTON_DOWN);
    GrMapWindow(w);

    for (;;)
    {
        GrGetNextEvent(&event);
        switch (event.type) {
            case GR_EVENT_TYPE_EXPOSURE:
                GrText(w, gc, 10, 30, "Hello World", -1, GR_TFASCII);
                break;
            case GR_EVENT_TYPE_BUTTON_DOWN:
                printf("click and move right !!!\n");
                GrMoveWindow(w,x+=20,20);
                break;
        }
    }
    GrClose();
    return 0;
}

=====================================================================

If I start the application above on top of nanowm - clicking into the
window,
only window content moves, but not the window itself. The window
decoration of 
nanowm

Starting the application without nanowm, it works fine !

What am I doing wrong ? Any suggestions ?

Thanks
Markus

Markus - 

This sounds like a bug with the window manager, nanowm.
When nanowm is running, programs aren't supposed to
call GrMoveWindow, since nanowm is supposed
to manage the windows location.  To get this to work,
you would need to modifiy nanowm so that it moves its
container window (that's the window frame) when the
child window move report comes in.  Look at 
nanowm source for more details on how it works.
I think the server reports window moves for
CHLD_UPDATE events.  If not, then the server
would need modification to report this event so
nanowm could handle it.

Greg
