List view column does not stay hidden

[Der_Andi]

Hi all,

I've got a listview with three columns. The first two columns have a width of 0, so they are hidden. But when I add new items, the second column gets visible. The first column stays hidden.

How can I prevent the second column from getting visible? Just setting it to 0 again seems to be not right for me.

Here's an example, demonstrating the problem:

#include <GuiConstantsEx.au3>
#include <GuiListView.au3>

GUICreate("", 400, 300)
$hListView = GUICtrlCreateListView("||items", 2, 2, 394, 268)

_GUICtrlListView_SetColumnWidth($hListView, 0, 0)
_GUICtrlListView_SetColumnWidth($hListView, 1, 0)

GUICtrlCreateListViewItem("hidden|hidden|visible", $hListView)
GUICtrlCreateListViewItem("hidden|hidden|visible", $hListView)
GUICtrlCreateListViewItem("hidden|hidden|visible", $hListView)

GUISetState()
Do
Until GUIGetMsg() = $GUI_EVENT_CLOSE

Not sure if this is what you looking for :

;...
GUICtrlCreateListViewItem("||visible", $hListView)
GUICtrlCreateListViewItem("||visible", $hListView)
GUICtrlCreateListViewItem("||visible", $hListView)
;...

Eh... is this a joke? :-P

Seriously, why would I create two hidden columns and leave them empty?

Der_Andi,

I am afraid I have not come up with anything better than rehiding the column each time you add an item.

Why do you want to have the first 2 columns hidden? Perhaps there is another way to do this.

Don't mix the native AutoIt GUI functions with the UDF functions if you can help it. It works fine if you use the UDF throughout:

#include <GuiConstantsEx.au3>
#include <GuiListView.au3>

$hGUI = GUICreate("", 400, 300)
$hListView = _GUICtrlListView_Create($hGUI, "hidden|hidden|visible", 10, 10, 380, 280)

_GUICtrlListView_SetColumnWidth($hListView, 0, 0)
_GUICtrlListView_SetColumnWidth($hListView, 1, 0)

For $n = 0 To 3
    _GUICtrlListView_AddItem($hListView, $n & "-0 hidden")
    _GUICtrlListView_AddSubItem($hListView, $n, $n & "-1 hidden", 1)
    _GUICtrlListView_AddSubItem($hListView, $n, $n & "-2 visible", 2)
Next

GUISetState()

Do
Until GUIGetMsg() = $GUI_EVENT_CLOSE

Interesting!

I didn't know that mixing native functions with UDF's can have such negative effects. I've been doing this ever since and everything worked out so far.

Thanks for the tip, PSalty.

@Melba:

I hope, it is okay with you, if I just use this solution. It would have been quite a story just to cover the basics of my program ;-)

Der_Andi,

Of course!

I was just looking for an alternative solution, but our resident waterfowl has come up with one for us.

I'd like to add, that there is indeed a way, how you can mix native GUI functions with UDF's. When using UDF's, make sure you use the handle of the control. Then it works, too. Or in my case: column widths do not change.

Creating listviews with _GUICtrlListView_Create() has one drawback: they are not affected by GUISetFont.

So I found the clue in this thread: http://www.autoitscript.com/forum/index.php?showtopic=70077&view=findpost&p=513807
