gtk widget change window title

To change the window title of a GTK widget using the C language, you can follow the steps below:

1. Include the necessary header file: #include <gtk/gtk.h>

2. Create a function to handle the window title change: c void changeWindowTitle(GtkWidget *widget, gpointer data){ // Code to change the window title }

3. Connect the function to the appropriate signal: c g_signal_connect(widget, "signal-name", G_CALLBACK(changeWindowTitle), data); Replace "signal-name" with the signal you want to connect to, such as "clicked" for a button widget.

4. Implement the code to change the window title within the function: c void changeWindowTitle(GtkWidget *widget, gpointer data){ GtkWindow *window = GTK_WINDOW(gtk_widget_get_toplevel(widget)); gtk_window_set_title(window, "New Window Title"); } Replace "New Window Title" with the desired title for the window.

5. Build and run the application to see the window title change when the connected signal is triggered.

Note: Make sure you have the necessary GTK development packages installed and linked against your project for the code to compile and run successfully.
