Hello all, I have a few doubts about the way I code my GTK applications. One of them is: Is it ok to use many global variables for the widgets? For example, in a glade app where callbacks are of the form
void callback(GtkWidget *widget) I can only have access to the widget that received the signal, but what if I want to make it change a property of another widget? Should I use a global variable or should I try getting the toplevel widget and then decending to the "neighbour" widget I want to make changes on? Also, what is the best way to get those "neighbour" widgets, if that is the case? On a programa I'm writing, I had to do the following: hostname = (char *) gtk_entry_get_text(GTK_ENTRY(((GtkBoxChild *) (GTK_BOX(gtk_widget_get_ancestor(widget,GTK_TYPE_HBOX))->children->next->data))->widget)); That doesn't look very neat, does it? In the case of a Glade app again, is it ok to have my GladeXML variable global or is that a bad programming style?
