I am making an applocation to demonstrate some algorithms, and I am using gtk2hs. When the user selects an algorithm, I want the whole window to change (different layout, input, output interface...). How could I do that? For example, is it possible to change the widget in a container? I tried a table but could not changed the content of a cell, so that doesn't seem like a good idea. Also I want to change the number of input fields according to another input field, and that seems like the same problem for me (removing widgets from a box) but it might be totally different in terms of solution. Thanks
How to change the content of a box, can you delete a widget from it? If yes, how?
Use widgetDestroy. See for example this tutorial.
