OK, I will do. As for what I see now (0.89pre7):
x11_handle_event:
if (ev->xcolormap.state == ColormapInstalled) {
DPRINTF("colormap uninstalled\n");
x11_colormap_installed = 0;
}
else if (ev->xcolormap.state == ColormapInstalled) {
x11_colormap_installed = 1;
DPRINTF("colormap installed\n");
}
2 times ev->xcolormap.state == ColormapInstalled - does not make sense
to me.
else if (ev->type == FocusIn) {
if (!x11_colormap_installed) {
DPRINTF("setting colormap\n");
XInstallColormap(x11_dpy, x11_colormap);
inited = 1;
}
}
- this could be a problem - I believe one does not get FocusIn without
window manager.
But XInstallColormap is also in X11_open. What the following comment
means?
/* Note: only single screen */
static PSD
X11_open(PSD psd)

OK, but it does not exist at the moment.
Another very nice feature would be to display nano-X directly on the root
(background) window as it does on framebuffer.
