GTK application does not show the image

[TArre.1]

Hi!

I am using STM32MP157C-DK2 board to create an application on the screen (using GTK library). My idea is to create a window with the following image inside:

Created code:

#include <gtk/gtk.h>
 
int main(int argc, char **argv)
{
    GtkWidget *window;
    GtkWidget *layout;
    GtkWidget *image;
    GtkWidget *button;
 
    gtk_init(&argc, &argv);
 
    window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
    gtk_window_set_default_size (GTK_WINDOW (window), 800, 480);
    gtk_window_set_title (GTK_WINDOW (window), "Info window");
    // gtk_window_fullscreen(GTK_WINDOW(window));
    gtk_window_set_position(GTK_WINDOW(window), GTK_WIN_POS_CENTER);
 
    layout = gtk_layout_new(NULL, NULL);
    gtk_container_add(GTK_CONTAINER (window), layout);
    gtk_widget_show(layout);
 
    image = gtk_image_new_from_file("linux.png");
    gtk_layout_put(GTK_LAYOUT(layout), image, 600, 50);
 
    button = gtk_button_new_with_label("PREVIOUS");
    gtk_layout_put(GTK_LAYOUT(layout), button, 150, 300);
    gtk_widget_set_size_request(button, 200, 50);
    g_signal_connect(G_OBJECT(button), "clicked", G_CALLBACK(gtk_window_close), window);
 
    button = gtk_button_new_with_label("NEXT");
    gtk_layout_put(GTK_LAYOUT(layout), button, 450, 300);
    gtk_widget_set_size_request(button, 200, 50);
    g_signal_connect(G_OBJECT(button), "clicked", G_CALLBACK(gtk_window_close), window);
 
    gtk_widget_show_all(window);
 
    gtk_main();
 
    return 0;
}

Then I have created executable using STM32CubeIDE and uploaded it with the image file (.png) in the following location:

• /usr/local

Finally, I have run the GTK application with the following command:

Board $> su -l weston -c "/usr/local/custom_GTK"

Obtained result:Does anyone know how I can display the image?

Thanks!

Hello @TArre.1​,

This kind of problem with GTK really let me think about a wrong path of your image. Try to mention the absolute path of the image (e.g. /usr/local/myimages/linux.png), or be careful to respect the right relative path of it.

Kind regards,

Erwan

Thank you @Erwan SZYMANSKI​ , with absolute path is working! 😁
