#include <gtk/gtk.h>
GtkWidget *window;
gint delete_event(GtkWidget *widget,GdkEvent *event,gpointer data)
{

gtk_main_quit();
return FALSE;
}

void hi(GtkWidget *widget , gpointer data)
{
GtkWidget *win;
GtkWidget *label;
label=gtk_label_new("MAN GTK RO DOST DARAM");
gtk_window_set_transient_for(GTK_WINDOW(win),GTK_WINDOW(window));
win=gtk_dialog_new_with_buttons("WELCOME",GTK_WINDOW(window),GTK_DIALOG_DESTROY_WITH_PARENT,"yes",-5,NULL);

gtk_container_add(GTK_CONTAINER(GTK_DIALOG(win)->vbox),label);
gtk_window_set_destroy_with_parent(GTK_WINDOW(window),TRUE);
gtk_widget_show(label);
int as=gtk_dialog_run(GTK_DIALOG(win));
if (as==-5){

gtk_widget_destroy(win);
}
}
int main(int argc , char *argv[])
{
gtk_init(&argc,&argv);

GtkWidget *button;
window=gtk_window_new(GTK_WINDOW_TOPLEVEL);
button=gtk_button_new_with_label("_SHOW DIALOG");
gtk_container_add(GTK_CONTAINER(window),button);
g_signal_connect(G_OBJECT(button),"clicked",G_CALLBACK(hi),NULL);

g_signal_connect(G_OBJECT(window),"delete-event",G_CALLBACK(delete_event),NULL);

gtk_widget_show(window);
gtk_widget_show(button);
gtk_main();
return 0;
}

And the second question GTK_DIALOG_MODAL is what kind of dialogue ? is it possible for you to show a form of this dialogue for me? :( ...

Using GTK_DIALOG_MODAL allows you to control whether or not the dialog is modal. A modal dialog stays above it's aparent window, only one instance can be created, and "disables" the user's ability to click in the parent window until they have clicked one of the dialogs buttons.

To kill you parent window, kill it in the function which is evaluating the dialog's response.

By the way, Andrew's book Foundations of GTK+ Programming has a whole chapter on using dialogs.
