How To Dynamically Add/remove Widgets From Gtk 3 Window

I am using python3 with Gtk3 and i need to basically remove some widgets from my Gtk.Window and replace them with other widgets when a Gtk.Button is clicked.I have tried using Gtk.

Solution 1:

I was baffled by this, too. It turned out the created widgets must be explicitly shown with show() or show_all(). In your case:

    row0.show_all()

as the last statement.
