Dialog trouble

[XPS]

Hi,

I have a dialog with a few buttons and a listbox. When I click a button, I want to change the height of the listbox.
The problem is, you can change things in a dialog before you have opened it.

In this case the dialog is allready open (because you need to click on a button).

How can I do this?

I would guess you're using global variables to change the value, if so just close the dialog & then create it again (AFAIK, there isn't a better way) -

Code: [Select]

closeDialog 0
_dlg = createDialog "Dialog"
? !(_dlg) : hint "Dialog error!"
Hope it'll work in your situation!

Closing and opening the dialog is a good idea.
But I still don't know how to change the height of a listbox. Can anyone give me an example of that?

Thanks

In your dialogue you have to create 2 listboxes the sizes that you want, then you hide and unhide them as needed using the "ctrlshow" command.

So there is no possible way to give a variable to the height of the listbox.
And change that before you create a new dialog?

Hey there !



There are ways, but :

• are you using a list box or a combo (i.e. a collapsable listbox) ?
• do you want to change the height of the entire listbox, or only the row heights ?

In any case, just assign a global variable in the description.ext to what you want to change, and adjust the variable after closing the dialog and on re-creating it, as nindall suggested.

Ah great.

The thing I did wrong:
I used _Height in my description.ext and my script.

I needed to use: Height
(Without underscore) 

So that is solved

But I need to know 1 more thing, what is the difference between a global variable and a local variable?
Is a variable with an underscore local or global?

[Igor Drukov]

The answer is in what you've just written

Underscore is local, without, global.
