Open File from Tree View

syno · December 27, 2008

Hi guys

I have just started using Autoit and was wondering if anybody can point me in the right direction here. I have a Tree View using the following control: GUICtrlCreateTreeView.

I want to list some files using the Tree View but then open those files when i double click one of the tree view items..

Any help would be greatly appreciated.

Thanks

Thanks for your help...

I will give that a go!!!

Hello again

My Tree View now has two branches, referencing the files on each branch to specific folders on the C: drive. I have done this by simply duplicated the lines as follows:

$cTreeView_MainItem = GUICtrlCreateTreeViewItem("Files", $cTreeView)

$cTreeView_MainItem2 = GUICtrlCreateTreeViewItem("Files", $cTreeView)

Dim $aFiles = _FileListToArray(@ProgramFilesDir & "\AutoIt3\Examples", "*.au3", 1)

Dim $aFiles2 = _FileListToArray(@ProgramFilesDir & "\AutoIt3\Examples2", "*.au3", 1)

For $i = 1 To $aFiles[0]

GUICtrlCreateTreeViewItem($aFiles[$i], $cTreeView_MainItem)

GUICtrlCreateTreeViewItem($aFiles2[$i], $cTreeView_MainItem2)

I know there is probably a better way of doing this but this is fine for now. The first branch works and I can select the files listed. However when trying to select the files on the second branch it fails saying that 'Windows cannot find' the location back to the file as it is referencing the location for the first branch....

It looks like I need to change this line somewhere in your example:

If $iItem <> 0 Then ShellExecute(@ProgramFilesDir & "\AutoIt3\Examples\" &

but I am not entirly sure where to go next with this. Would it be possible to use this second branch in the same way as the first branch but reference a different set of files, lets say from another folder...

Thanks

~~I think, if you use the built-in functions to create the items, the CTRLID is saved as itemparam. So, if you change it, the GUICTRL functions won't work anymore.~~

Edit: no, works. with hanged param, too.

I didn't know about that.

So, if you change it, the GUICTRL functions won't work anymore. Right?

So if CTRLID is really saved in itemparam then of course you are right.

In this example CTRLID for treeview items are not used so it will be OK even if it's destroyed but generally it may be problem.

Correct solution would be to use of i_GUICtrlTreeView_Add ()/_GUICtrlTreeView_AddChild() nstead of GUICtrlCreateTreeViewItem()

EDIT: My examples works OK I tested them successfully
