Hi,
Thanks for your reply. this is the code and its from example from youtube. the problem is in this part:
if(0 == gtk_builder_add_from_file (builder, "myui.glade", &err))
{
/* Print out the error. You can use GLib's message logging */
fprintf(stderr, "Error adding build from file. Error: %s\n", err->message);
/* Your error handling code goes here */
}
i created the file using glade designer and now i want to add it in stm32 cube ide user space project.
// My Application
//
// By (Your name)
// Libraries
#include <gtk-3.0/gtk/gtk.h>
#include <stdio.h>
// Variables
GtkWidget *window; // Window
GtkLabel *mylabel; // Label
GError *err = NULL; /* It is mandatory to initialize to NULL */
// Main function
int main(int argc, char *argv[])
{
GtkBuilder *builder; // GTK Builder variable
gtk_init(&argc, &argv); // Start GTK
builder = gtk_builder_new(); // Create GTK UI Builder
//gtk_builder_add_from_file(builder, "myui.glade", NULL); // Load our UI file
if(0 == gtk_builder_add_from_file (builder, "myui.glade", &err))
{
/* Print out the error. You can use GLib's message logging */
fprintf(stderr, "Error adding build from file. Error: %s\n", err->message);
/* Your error handling code goes here */
}
// Assign the Variables
window = GTK_WIDGET(gtk_builder_get_object(builder, "MyWindow")); // Load our window named MyWindow
mylabel = GTK_LABEL(gtk_builder_get_object(builder, "MyLabel")); // Load our label named MyLabel
// Essential for a GTK based program
gtk_builder_connect_signals(builder, NULL);
g_object_unref(builder);
gtk_widget_show_all(window); // Show our window
gtk_main(); // Run our program
return 0; // Necessary for a c main function
}
// Function to exit our app
void exit_app()
{
printf("Exit app \n"); // Not neccesary
gtk_main_quit(); // Command to quit a GTK program
}
// Function when our button is pressed
void button_clicked()
{
printf("Button clicked \n");
gtk_label_set_text(mylabel, "Hello World");
}
