Hello,

For some time I've been using the UDF from Melba23 called 'GUIScrollbars_Ex.au3' (no modifications) to add scrollbars when a specific gui was getting too large (many controls).

It works like a charm except for when I'm using a lot of controls on the gui. That seems to make the creation of the gui flicker somewhat.

I've been looking around here to find a possible solution, but until now I did not find any.

Here is a simplified (....) version of the script, so the amount of controls is the same, but the data shown is minimal.

When I outcomment line 275 (the _GUIScrollbars_Generate part) it does not flicker (but the scrollbars won't work either).

#include <EditConstants.au3>
#Include <GuiListView.au3>

So how could I still have (working) scrollbars, but get rid of the flickering.

Other comments are welcome also, since I like to learn!

I did attach the GUIScrollbars_Ex.au3 file, which I downloaded from this forum, just to have a working example from this post without having to look for the file.

Thanks in advance,

Peter

What an impressive gui, man!

I've tried creating the scrollbars just after creating the gui and there is no flickering:

$hGUI = GUICreate("Lines menu : x for cyclus: " & $sCyclus, $iGWidth, $iGHeight,0,0,BitOR($WS_VSCROLL,$WS_MINIMIZEBOX,$WS_MAXIMIZE,$WS_MAXIMIZEBOX,$WS_CAPTION,$WS_POPUP,$WS_SYSMENU,$WS_HSCROLL))
_GUIScrollbars_Generate($hGUI, $iGWidth + $iDiffW, $iGHeight + $iDiffH)

(line 50 of your code).

Just curiosity: What does the program do?

Yes, that did the trick!

Thanks a thousand.

Would never have thought of that!

For the satisfaction of your curiosity, it is in use for the calculation of weekly menu's (food) for our customers (we produce meals).

So all the little listviews represent a grid of day (horizontal) / menu (vertical) combinations, where all the 'items' are show on the left listview.

The numbers are the average, min and max prices given the actual food prices for our production facility.

The 'real' gui is more flexible as it allows the user to tell per 'menu' how many days, weeks and menu's it needs.

The concept is actually rather simple with a few SQL tables that populate the gui and some checkboxes.

Works like a charm, except for the flickering.

Which is gone now. Thanks for that!
