Limitations of ListBox, ListView?

Burgaud · April 16, 2018

Listbox can retain the Highlight even if the listbox is not in focus.

Whereas a ListView looses Hightlight when it is no longer in focus.

A Listbox cannot change color/font of an item.

Listview can.

Am I correct?

I am stuck for the last week or so figuring out how to do maintain highlight and I need ability to change color/font of selection. I have been shuffling between ListBox and ListView. I know there are sample scripts of listview sustaining highlights, but the codes are too cryptic to easily comprehend.

Regardless of the language used, you're going to have to do some code wizardry to get it working.

Not so. By default, an Autoit ListView retains the selection when focus is removed because of the $LVS_SHOWSELALWAYS style. What you and others have found is that the default Windows colours for the ListView background and the "selected but not in focus" item are very close (0xFFFFFF vs 0xF0F0F0) which makes the still-selected item quite hard to see on some monitors. If you change the ListView background colour you can see the item much more clearly when focus is lost:

#include <GUIConstantsEx.au3>
#include <GUIListView.au3>

$hGUI = GUICreate("Test", 500, 500)

$cLV = GUICtrlCreateListView("", 10, 10, 200, 200)
GUICtrlSetBkColor($cLV, 0xC4C4C4)
_GUICtrlListView_AddColumn($cLV, "Col 0", 85)
_GUICtrlListView_AddColumn($cLV, "Col 1", 85)

For $i = 0 to 5
    GUICtrlCreateListViewItem("Item " & $i & "|SubItem " & $i, $cLV)
Next

$cButton = GUICtrlCreateButton("Get Focus", 10, 300, 80, 30)

GUISetState()

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch

WEnd

Still not it.

What i am referring to is the blue highlight when you click on a listview item. i need to retain that color when I click on some other GUI.

Listboxes maintains *that* highlight color; but Listview highlight turns gray when I click away which is not what I want.

Here is what I have been testing out:

The top ListView retains the highlight (albeit in dark gray). However, I could not make it work on my script.

I am stuck. and need help.

Thanks.

Burgaud,

have you looked at my GUIListViewEx UDF (the link is in my sig)? It allows you to retain the "selected" colour when the ListView is not focused - Example 6 is the one to run.

Melba,

not yet.

will test that out and see how it goes.
