Probably a basic question; Build a gui upon button click

Recommended Posts


I go a question, probably a pretty easy and/or dumb one, but still; can't figure it out...

Here it is;

I go myself a cute little gui, containing a button;

The button is $but1. But1 creates a new button, $but2:

Case $but1
          $but2 = GUICtrlCreateButton("button2", 400, 696, 97, 65)
                 Case $but2

This doesnt work. It simply exits with a variable undeclined warning, which is obvious, since I only create the button upon but1 click.

Is it nessecary to define $but2 somewhere before or how can I do this?

Maybe I should make the question a bit different; more to the point:

I want to create a GUI, which changes when clicked. So all elements on it should be removed and new elements should be places. How can I do this easily?

Who can help this beginner out?


(ps, very shamefull, 2 stupid typo's in the title.. cant edit it..)

Im first off going to assume that you had already started the switch, inside a loop, and are testing the guigetmsg() function.

So the problem would be that, if your program runs through the switch, it will test

Case $but2

if you had not clicked on the first button by then, $but2 would not exist, and so it will throw an error. what you could do to solve that is just to create

Global $but2 = 15000

or something like that, just so that autoit will recognize that yes, the variable exists, but as we are testing guigetmsg(), it is not 15000.

dont do that, though, its kind of a bad way to get around it, i would say. just create $but2 from the start, but set its state as hidden. then, when you are running through case $but1 in the switch, do

GUICtrlSetState ($but2, $GUI_SHOW)

so all in all, it would be something like

#include <ButtonConstants.au3>
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
$Form1 = GUICreate("Form1", 179, 126, 192, 124)
$But1 = GUICtrlCreateButton("Click me", 40, 24, 75, 25)
$But2 = GUICtrlCreateButton("New Button", 40, 64, 75, 25)
GUICtrlSetState($But2, $GUI_HIDE)
While 1
$nMsg = GUIGetMsg()
Switch $nMsg
  Case $But1
   GUICtrlSetState($But2, $GUI_SHOW)

Hm, yeah, thanks, thats a smart idea.

There's just one nasty disadvantage; I need to enable and disable all controlls at every button. For instance, $but3 should enable $but4, then I should hide all other controls at every other click.

Case $but1

          Case $but2

And so on..

Not really convenient when having over 100 different items, check boxes, buttons etc..

Isn't it possible to for instance group a load of controlls and then show or hide them all at once?

Unfortunately not. You could put the ControlIDs into an array which would let you use a For...Next loop to run through them pretty quickly. :)

But if you are really dealing with over 100 controls, I would seriously reconsider your GUI design. Perhaps take a look at my GUIExtender UDF (look in my sig for the link) - this will let you open and close sections of your GUI and might be a better way to deal with so many controls. :D


P.S. I amended the thread title for you - see the first post for more details. ;)

Thanks! Still cant find it to be honest :)

I'm gonna give the guiextender udf a try. Maybe that'll create less work ;)
