GTK+ C example with GUI created using Glade

This post show how to create GUI using Glade, and link the generated glade file in c code, then compile with gcc with GTK+ 3.0, to generate a executable program.

- Start glade, create something. Specify the window in TOPLEVEL with name "myname". Save as "testGlade.glade". We will refer them in our c code.

Create GUI with Glade

- Create our c source code, "test.c".

#include <gtk/gtk.h>

int main(int argc, char *argv[])
{
    GtkBuilder *gtkBuilder;
    GtkWidget *window;
    gtk_init(&argc, &argv);
    
    gtkBuilder = gtk_builder_new();
    gtk_builder_add_from_file(gtkBuilder, "testGlade.glade", NULL);
    window = GTK_WIDGET(gtk_builder_get_object(gtkBuilder, "mywindow"));
    
    g_object_unref(G_OBJECT(gtkBuilder));
    gtk_widget_show(window);
    gtk_main();
    
    return 0;
}

where "mywindow" is the window defined in Glade. And "testGlade.glade" is our saved glade file.

- Compile it with command:
$ gcc -Wall -g -o testGlade test.c `pkg-config --cflags --libs gtk+-3.0`

Where testGlade is the target executable file. Run it:
$ ./testGlade

Because we have do nothing on the code. The program just show a menu bar without action.

Remark:

It's commented to use following command:
gcc -Wall -g -o testGlade test.c $(pkg-config --cflags gtk+-3.0) $(pkg-config --libs gtk+-3.0)
