How to expand a tree view using AutoIt - autoit

Question

The UI is as following:
The tool "AutoIt Window Info" can only locate the elements in red (red rectangle area), the sub items can not be located.
So how can I expand or operate these items？

Answer 1

Usually Windows controls can be accessed using keystrokes as well.
In the screen-dump the Farmtt element is selected. That would be your starting point.
You may try:
Send("{DOWN}") Move down an element.
Send("{TAB}") Navigate to next control (button, checkbox, etc)
Send("{NumPadMult}") Recursively expands folders in a SysTreeView32.
Send("{ENTER}") ENTER key on the main keyboard
etc.

Answer 2

There are two things over here:
1) Use the following code snippet:
;Gets the handle for the text
Func readFirstlevelTreeNodes($hWndCtrl)
Local $firstItemHandle = _GUICtrlTreeView_GetFirstItem ($hWndCtrl)
Local $iCount = _GUICtrlTreeView_GetSiblingCount( $hWndCtrl, $firstItemHandle )
Dim $aRet[$iCount]
$aRet[0] = $firstItemHandle
For $index = 1 To $iCount - 1
$aRet[$index] = _GUICtrlTreeView_GetNextSibling ( $hWndCtrl, $firstItemHandle )
$firstItemHandle = $aRet[$index]
Next
getTreeNodeTextList($hWndCtrl,$aRet)
EndFunc
; Gets the text for given sibling node handle lists
Func getTreeNodeTextList($hWndCtrl,$aRet)
ConsoleWrite("Tree Node first level list"&#CRLF)
For $index = 0 To Ubound($aRet) -1
ConsoleWrite(_GUICtrlTreeView_GetText ( $hWndCtrl, $aRet[$index] )&#CRLF)
Next
EndFunc
You may see the output for the first level tree nodes.
2) If you still dont see the output then please verify the control handle values and window handles. If they are correct and it still doesnt show the first level tree nodes then try running your sciTE editor as administrator.
I think this should help.
