Hi,
I've made an application using gtkmm for GUI and Ogre3D to ember 3D
rendering inside the GUI. Everything works fine up to gtkmm 2.8.8 (and
corresponding dependency). But it crash systematically when using more
recent version (for exemple current stable version gtkmm 2.10 and glibmm
2.12).
Here is message I get :
The program '********' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
(Details: serial 229 error_code 8 request_code 152 minor_code 1)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error()
function.)
To embed Ogre3D into gtkmm, I derive a class from Gtk::Socket and here
is a part of the code :
mGdkWindow = get_window();
if(!mGdkWindow) throw std::runtime_error("OgreWidget gdkwindow was not
created in time\n");
GdkWindow* parent = mGdkWindow->gobj();
GdkDisplay* display = gdk_drawable_get_display(GDK_DRAWABLE(parent));
GdkScreen* screen = gdk_drawable_get_screen(GDK_DRAWABLE(parent));
Display* xdisplay = GDK_DISPLAY_XDISPLAY(display);
Screen* xscreen = GDK_SCREEN_XSCREEN(screen);
int screen_number = XScreenNumberOfScreen(xscreen);
// XID xid_parent = (XID)get_id();
XID xid_parent = GDK_WINDOW_XWINDOW(parent);
And here is the string I give to Ogre to create its rendering window :
sprintf(Xembed, "%d:%d:%d", xdisplay, screen_number,
xid_parent);
Any help would be really appriciated !
