Is it possible to add a gtk_layout to a gtk_layout?
I’ve tried and it appears that the second layout receives signals (map, show,
etc) but nothing is rendered.
FWIW the gtk_layout seems like the best container for what I’m trying to do. No
scrolling is required and
widgets can be placed ad-hoc. I’d like to use the second gtk_layout to provide
a simple mechanism to
show / hide a collection of widgets (without having to show / hide them
individually).
Using gtk 3.14.13 on CentOS7
The sample code below (for me) doesn’t display the ‘Button’.
Any insight appreciated ...
-Greg.

#include <gtk/gtk.h>
int main( int argc, char *argv[])
{
GtkWidget *window;
GtkWidget *layout1;
GtkWidget *layout2;
GtkWidget *button;
gtk_init( &argc, &argv );
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_window_set_default_size(GTK_WINDOW(window), 1024, 1024);
layout1 = gtk_layout_new(NULL, NULL);
gtk_container_add(GTK_CONTAINER (window), layout1);
layout2 = gtk_layout_new(NULL, NULL);
gtk_container_add(GTK_CONTAINER ( layout1 ), layout2);
button = gtk_button_new_with_label("Button");
gtk_layout_put(GTK_LAYOUT( layout2 ), button, 150, 50);
g_signal_connect_swapped(G_OBJECT(window), "destroy",
G_CALLBACK(gtk_main_quit), NULL);
gtk_widget_show_all( window );
gtk_main();
return 0;
}
