Hi,
I would like some help to solve a GTK+ problem, since I am working with this
GUI library for the first time.
I want to create some clickable boxes with a background image. I am using a
GtkEventBox with a GtkImage inside, as I read on the API. This is my
function for setting the background image:
static void set_box_image(struct game_data *d, gint box_index, gint
img_index) {
gchar file[40];
sprintf(file, "/usr/share/pixmaps/100boxes/%d.png", img_index);
GtkWidget *img = gtk_image_new_from_file(file);
GtkWidget *old = gtk_bin_get_child(GTK_BIN(d->base[box_index]));
if (old != NULL) {
gtk_widget_destroy(GTK_WIDGET(old));
}
gtk_container_add(GTK_CONTAINER(d->base[box_index]), GTK_WIDGET(img));
gtk_widget_show(img);
}
where d->base is an array of GtkEventBox items.
The problem is that sometimes the images appear with inverted colors (i.e.
in negative). It happens in an inconsistent manner, I have not been able to
spot the cause so far.
I suspect it has to do with GtkWidget states, so I tried to set the state
programmatically (both for the GtkEventBox and the GtkImage), but that did
not solve the problem.
Thanks for your attention.
Best wishes
Floriano
