Problem with control positions when resizing child gui


Recommended Posts

Hello there.

I'm quite new to AutoIt and have been lurking the forum for a while now. I've found most of the answers for my previous problems on the forum, but not for this one.

My script makes a GUI and a child GUI with Melba23's Scrollbars, then it adds Edit controls to the child GUI. The controls work fine at first, but when the scrollable area gets bigger and I try to resize the window, they flip out.

Code is pretty messy, but I hope you can work it out.

Thanks in advance.

Chuba,

You do not need both the UDF #include files - in fact you will get an error if you try to as they both contain a _GUIScrollbars_Restore function. From what I can see you only need the GUIScrollbars_Size UDF - replace your _GUIScrollbars_Restore function with _GUIScrollbars_Restore. :doh:

When you add controls to a scrollable GUI, you need to scroll the GUI to the top before you do so - this post from a few days ago shows how to do it. If you do not do this the controls position strangely as you have found - an explanation can be found here. :bye:

Finally, why are you even adding multiple edit controls - one for each entered line? As you can only enter single lines, why not use a list control which looks after its own scrollbars? :oops:
