ListView - Autosize Height

[zbatev]

Hi AutoIT GUI masters!

I was wondering if you could help me out on a little challenge that I have...

I want to use a ListView that has a possible listing(items) between 0 to 30. But I wanted the form and the control to auto-adjust it's height according to the number of items in the ListView control.

Maybe this UDF, by Melba23, can help - GUIListViewEx. I don't know if this UDF has the ability to do any 'autosizing', so it's up to you to read up on it! Good luck!

That is a very good ListView UDF however it doesn't have what I was looking for...Hmmmmm...

Look at GuiCtrlSetPos in the help file, you can use it by adjusting the Height parameter to however many items are in your listview, while keeping the other parameters the same as when you created it.

You can think many ways to do that, this is one of them.

#include <GuiListView.au3>
Opt("GUIResizeMode",545) ; $GUI_DOCKTOP + $GUI_DOCKHEIGHT
global $n = 0
global $items[1]
$hGui = GuiCreate("AutoSize my monoscout999",-1,199)
$iButton1 = GuiCtrlCreateButton("Add Item", 260,20,120,50)
$iButton2 = GuiCtrlCreateButton("Delete Item", 260,100,120,50)
$iList = GuiCtrlCreateListView("Nª|Listview test|blabla",0,0,250,200)
$hList = GuiCtrlGetHandle($iList)
GuiSetState()
While True

            redim $items[$n]
            $items[$n-1] = GUICtrlCreateListViewItem($n&"|Some text|more text", $iList)
            $Height = _GUICtrlListView_ApproximateViewHeight($hList)
            $pos = wingetpos($hGui)
            If $pos[3]-27 < $Height Then
                winmove($hGui,"", $pos[0],$pos[1],$pos[2],$Height+30)
                GUICtrlSetPos($iList,0,0,250,$Height+30)

            $pos = wingetpos($hGui)
            If $pos[3]-27 > $Height and $pos[3]-27 > 200 Then

As always monoscout999, nice and brilliant code! This is exactly what i need. Thank you!

GUICtrlSetPos() is not needed if you use GUICtrlSetResizing() for ListView control.

In this case only WinMove() will do the job for you.
