Get column header type from Listview control

[pammi]

Hi all,

how to retrieve the column header type from Listview control. In my example, the first column is of checkbox header type and I need to fetch whether its enabled or not.

[Melba23]

pammi,

Dog eaten your Help file?

Try looking at _GUICtrlListView_GetItemChecked - that works for me.

Not sure, but I think the OP is searching more for something like this:

Global Const $HDF_CHECKBOX = 0x0040 ; Windows Vista and Version 6.00. The item displays a checkbox. The flag is only valid when the HDS_CHECKBOXES style is first set on the header control.
Global Const $HDF_CHECKED = 0x0080 ; Windows Vista and Version 6.00. The item displays a checked checkbox. The flag is only valid when HDF_CHECKBOX is also set.
$h_Report_ListView_Header = _GUICtrlListView_GetHeader($hListview)
For $i = 0 To _GUICtrlHeader_GetItemCount($hListview) - 1
 $iFormat = _GUICtrlHeader_GetItemFormat($hListview, $i)
 If BitAND($iFormat, $HDF_CHECKBOX) Then ConsoleWrite("Column " & $i & " is of the typ HDF_CHECKBOX" & @CRLF)
 If BitAND($iFormat, $HDF_CHECKED) Then ConsoleWrite("Column " & $i & " is of the typ HDF_CHECKED" & @CRLF)
Next

@KaFu,

does the $HDF_CHECKBOX and $HDF_CHECKED value change for windows XP.

[KaFu]

Styles are only valid for Windows Vista+. Maybe post a screenshot of what you want.

Melba23,

_GUICtrlListView_GetItemChecked doesn't work for column header.

[pammi]

@KaFu,

the column header is of sysheader32 type and the first column has a checkbox. I want to validate whether it exists or not.

il attach the screenshot later.

[pammi]

I mean the checkbox is in the first column header.

[pammi]

@KaFu,

attached is the snapshot of the app.I am trying to fetch the column header type of the first coulmn i.e checkbox.

What application are you using? Also, have you tried using the Au3Info tool on the header to see what it displays for the checkbox you're trying to get information from?

[pammi]

Its an windows application. Au3info tool doesn't fetch anything when pointed at the checkbox. It fetches the sysheader32 info of the column header as a whole.

Is there any way to fetch the column header type using the index?

[BrewManNH]

I'm pretty sure that I had figured out it was a Windows application, my question was which Windows application are you trying to interact with? What information do you get when you point it at the header, what is in the output pane of the info tool? All I have from you right now is it's a windows program with a listview, and nothing else. See why it's hard to figure out the answer to your questions yet?

There is no column header type to retrieve, a header checkbox in XP is a custom modification.

The checkbox is either a child Button class control of SysHeader32, some non-MS class of listview/header/button or drawn.

What is the listview class?

You may need another tool like Winspector Spy, Ranorex or Window Detective to get the button info.

If the AU3Info tool is not getting any info from the button, then it may be a custom class or drawn and not readable.

I use a listview header checkbox in a script (written for XP)

It looks like this in Winspector Spy or WinGetClassList($hListView)

SysListview32

|_Sysheader32

|_Button

Something like this might return the button handle, then get the state.

#include <GuiButton.au3>

$hWin = WinGetHandle("[TITLE:YourApp]")
If Not IsHWnd($hWin)Then Exit ConsoleWrite('!No App hWnd returned' & @crlf)

$hListView = ControlGetHandle($hWin, "", "[CLASS:SysListView32]")
If Not IsHWnd($hListView)Then Exit ConsoleWrite('!No ListView hWnd returned' & @crlf)

$hBtn = ControlGetHandle($hListView, "", "[CLASS:Button]")
If Not IsHWnd($hBtn)Then Exit ConsoleWrite('!No Button hWnd returned' & @crlf)

$iRet = _GUICtrlButton_GetCheck($hBtn)
If $iRet = $BST_CHECKED Then ConsoleWrite('+Button is checked' & @crlf)

$iRet = ControlCommand($hBtn, "", $hBtn, "IsChecked", "")
If $iRet = 1 Then ConsoleWrite('+Button is checked' & @crlf)

@BrewManNH,

Sorry I should have posted the info long back.its a C++ application. Below are the information about the column header from Au3info tool.

@rover,

Window Detective, Au3info tool is not identifying the checkbox in the header as a button. I used the below code and its not returning any handle to the button. Please have a look at the information about the header from Au3info above.

#include <GuiButton.au3>

$hWin = WinGetHandle("ABC")

msgbox(0,"",$hWin)

If Not IsHWnd($hWin)Then Exit ConsoleWrite('!No App hWnd returned' & @crlf)

$hListView = ControlGetHandle($hWin, "", "[CLASS:SysHeader32; INSTANCE:2]")

msgbox(0,"",$hListView)

If Not IsHWnd($hListView)Then Exit ConsoleWrite('!No ListView hWnd returned' & @crlf)

$hBtn = ControlGetHandle($hListView, "", "[CLASS:Button]")

msgbox(0,"",$hBtn)

If Not IsHWnd($hBtn)Then Exit ConsoleWrite('!No Button hWnd returned' & @crlf)

[BrewManNH]

The strange thing is, that style setting for the header doesn't indicate that it has "$HDS_CHECKBOXES" (0x00000400) set on it. That number indicates it has WS_CHILD | WS_VISIBLE | HDS_HORZ | HDS_BUTTONS | HDS_DRAGDROP | HDS_FULLDRAG set. I got that information from here. So I'm not sure if you can get that information with AutoIt.

[pammi]

thanks for the info BrewMan. The links explains everything.

Looks like no child MS Button class control in listview #2's header

The listview and/or header may be ownerdrawn (unreadable with standard listview/header APIs) or using an imagelist (may be non-MS standard imagelist)

There could be a header imagelist and hit testing used to change the image state.

You may be able to get the items imagelist index for the checked/unchecked state.

However, the placement of the checkbox in the image you posted suggests it is not

an MS imagelist item as is not as indented as a header imagelist item is.

Try this script, it will check if the listview is ownerdrawn.

As a last resort, you could check pixel colour of the checkbox...

Good Luck
