[tutorial] GUI buttons not depressing

[vlovich]

I recently came across this in my program where despite the fact that I was doing exit when GUI.ProcessEvent, my buttons did not depress.

here is an example

code:

setscreen ("offscreenonly") var but1 := GUI.CreateButton (0,0,0, "Button 1", [i]buttonProc1[/i]) var but2 := GUI.CreateButton (10,10, 0, "Quit", GUI.Quit) loop     exit when GUI.ProcessEvent end loop

the solution turns out to be

code:

setscreen ("offscreenonly") var but1 := GUI.CreateButton (0,0,0, "Button 1", [i]buttonProc1[/i]) var but2 := GUI.CreateButton (10,10, 0, "Quit", GUI.Quit) loop     setscreen ("nooffscreenonly")     exit when GUI.ProcessEvent     setscreen ("offscreenonly") end loop

the obvious advantage of switching between the two in the second example is that you want the button to look nice but don't want ugly flickering if your doing animation with View.Update (for turing 4)[/i]

thats because of how GUI is structured. Another way of solving it would be to ether place View.Update inside the loop or throughout the GUI module.
