Dynamically adding widgets to a window on button click

[Harinandan S <harinandans gmail com>]

Hi All,

I am trying to add widgets to a window on clicking a button. When a button is clicked, in the callback I add a few buttons and entry boxes to a vbox and add attach it to another vbox and show all the widgets created.

However, I notice that it is not showing the widgets I've created when I click the button. Its showing the widgets added if I call the callback function myself while creating the window before calling gtk_main();

Is this approach right to add widgets at runtime to a window?
