Window placement and movement is something which the Window Manager deals with, and as such it depends which desktop environment you are using. For example, in XFCE, you can alt + left-click anywhere on a window and then drag to move it about.

WindowMaker also works by using ALT+left-click-drag.

i tried this

Code:

#include <gtk/gtk.h>
#include <gdk/gdkkeysyms.h>


/* prototypes */
void
on_button_press (GtkWidget *widget, GdkEventKey *event, gpointer user_data);


int main (int argc, char *argv[])
{
    GtkWidget *window;
  GtkWidget *eventbox;
 
    gtk_init (&argc, &argv);
   
    window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
  eventbox = gtk_event_box_new ();
  gtk_widget_show (eventbox);
  gtk_container_add (GTK_CONTAINER (window), eventbox);

  gtk_window_set_type_hint (GTK_WINDOW (window), GDK_WINDOW_TYPE_HINT_TOOLBAR);
//gtk_window_set_opacity (window,0);
   
    /* connect signal callbacks */
    g_signal_connect (G_OBJECT (window), "destroy",
                    G_CALLBACK (gtk_main_quit), NULL);
          gtk_signal_connect(GTK_OBJECT(eventbox), "button_press_event",
		     GTK_SIGNAL_FUNC(on_button_press), NULL);

                   
    gtk_widget_show_all (window);
   
    gtk_main ();
 
    return 0;
}

void
on_button_press (GtkWidget *widget, GdkEventKey *event, gpointer user_data)
{
//event->keyval == GDK_Alt_L;
g_print("hiiiiiiiiiiiii \n");

}

and compiled
gcc -Wall -g `pkg-config --cflags --libs gtk+-2.0` -o pointer pointer.c

but not getting the window movement...

please help me with this code

thank you inadvance

It is not something in your code. The window manager is what controls this, not the programs themselves. If your window manager intercepts alt-left drag, your application probably won't even see the event.

*Bangs head against wall*. What don't you understand about matthewg42's post (particularly the first sentence)?

This has to be a language problem.

Munna, changing your code cannot fix the problem. Window movement is part of your window manager, which is part of your desktop environment if you use something like KDE or Gnome.

hi
if we click on the tittlebar and drag the window will move..

how can it will be moving?
if we click on the middle of the window it doesnt move
how to move like this

please help me

thank you in advance

Let me try to explain. What you want to do is *not* controlled by your program. It is controlled by the *window manager*. You can't write code into your program which will make the window movable by clicking and dragging on the middle of the window. Most window managers will do nothing when you click and drag on the middle part of the window. Clicking on the middle of the window causes the window to be focused under most window managers, but dragging from the middlw will do nothing. However, several window managers will allow you to drag from the middle of the window if you press the ALT key while dragging with button 1 of the mouse.
The only way to get your program to do what you want would be to include code which intercepts all clicks on the desktop -basically disabling the window manager which you probably do not want. You might examine the code from programs for handling desktop icons to find a way to do this(ROX-Filer and fbdesktop are two examples). However the icons are unbordered windows which may not be what you want.
