Please help: How to embed a X window in a GTK window?

2008-03-02 Thread Ke Jin

Dear All,
   I am working on a project whose code was written in Xlib and now I  
need to develop a GUI for it. I want to use GTK so I wonder if I could  
embed the former xlib window into a GTK top-level window. I wrote a  
small test program as below but it doesn't work. Does anyone have any  
idea about how this is gonna work?

#include string.h
#include X11/Xlib.h
#include X11/keysym.h
#include gtk/gtk.h
#include gdk/gdkx.h
#include stdlib.h
#include stdio.h
#include sys/types.h

void destroy (GtkWidget *widget, gpointer *data)
{
 gtk_main_quit ();
}



int main(int argc, char* argv[])
{
 Display* display = XOpenDisplay(NULL);
 int screen = DefaultScreen(display);
 int width = DisplayWidth(display, screen)/6;
 int height = DisplayHeight(display, screen)/6;
 GtkWidget *gtkWin;
 XEvent e;
 pid_t pid;
 Bool child = FALSE;
 int timer = 0;

 gtk_init (argc, argv);

 gtkWin = gtk_window_new(GTK_WINDOW_TOPLEVEL);

 gtk_signal_connect(GTK_OBJECT(gtkWin),  
destroy,GTK_SIGNAL_FUNC(destroy),NULL);

 gtk_widget_realize(gtkWin);

 Window win = XCreateSimpleWindow(display, RootWindow(display,  
screen),
   0, 0, width, height, 3, BlackPixel(display, screen),  
WhitePixel(display, screen));
 XStoreName(display, win, hello);
 GC gc = XCreateGC(display, win, 0, NULL);

 XMapWindow(display, win);

 XSelectInput(display, win, ExposureMask|ButtonPressMask);

 if((pid = fork()) 0 )
 {
 perror(fork);
 exit(1);
 }
 else if(pid  0)
 {
 printf(parent\n);

 XReparentWindow(display,win,GDK_WINDOW_XID(gtkWin-window), 
50,50);
 XMapWindow(display,GDK_WINDOW_XID(gtkWin-window));
 gtk_widget_show(gtkWin);


 gtk_main();

 }
 else
 {
 printf(child\n);

 while(1)
{
XNextEvent(display, e);
if(e.type==Expose  e.xexpose.count1)
{
 XDrawString(display, win, gc, 10, 10, Hello World!,  
12);

 }
else if(e.type==ButtonPress)
 {
XCloseDisplay(display);
break;
}
 else
 {
 }
 }
 }


 return 0;
}


Thanks  Regards,
Kay

I don't think this way can work. To embed a X window in Gtk window, I
think you must handle the redraw event of the X window and manually
copy the drawables to the Gtk+ window.

Look into GtkPlug or something like this... where windowid is the Xid of
a window. And window is a gtk_window object

if (windowid != 0) {

window_container = gdk_window_foreign_new(windowid);
if (GTK_WIDGET_MAPPED(window))
gtk_widget_unmap(window);

gdk_window_reparent(window-window, window_container, 0, 0);

}

Maybe that was the wrong code in gnome-mplayer. I think that was the
code to embed gnome-mplayer into an X window. Sorry.

short-cut accelerators

2008-03-02 Thread Carlos Pereira

Hi,
Could someone show me how to create a shortcurt to a menuitem, using an 
accelerator group? on GTK 1.2* I used the code below. What is the 
equivalent in GTK 2.12?

accel_group = gtk_accel_group_new ();
gtk_accel_group_attach (accel_group, GTK_OBJECT (window));
gtk_widget_add_accelerator (menu_item, activate,
accel_group, 'c', GDK_CONTROL_MASK, GTK_ACCEL_VISIBLE);
