Color ListView row built with UDF

3 posts in this topic

Hello all,

I have built a GUI using UDFs that displays a ListView with select services and specific information. The ListView has 4 elements in each row and has a Checkbox which may be either checked or unchecked based on information at that moment. I've been asked to also color the rows, based on certain information ('red' means this, 'green' means that, etc..) to allow better visual indication to the user.

I've built this ListView with all _GUICtrlListView.... functions which allowed me (as best I could determine) to dynamically create 4 columns, with checkboxes, with 'pre-sized' widths, and is sortable.

I'm trying find a way to preserve all the current functionallity and checkboxes, and also be able to color individual rows (the entire row, not just 1 column of a row, not just an image bitmap, etc.)

I've tried to rewrite the code below with standard 'GUICtrlCreateListView' type functions and it seems I loose some of the functionallity/ flexibility.

I'm getting the impressions after reading Melba23's post that this may not be so simple with UDFs:

I've looked at BugFix's great UDF, but this only appears to do a 'cell', not an entire row.

$Button_3 = GUICtrlCreateButton("Disable All", 110, $bTop, $bSize)

; > This supplies 4 of the pieces of information displayed in the ListView.<
Global $runArray[1][8], $z = 0
; - Stuff happens to populate $runArray...
; ------------------------------------------------------------------------------------------------

; - Populate the ListView and Check chechboxes based on the value of $runArray[$z][7]
For $z = 0 To UBound($runArray) - 1
    _GUICtrlListView_AddItem($hListView, $runArray[$z][0], -1, $z)
    _GUICtrlListView_AddSubItem($hListView, $z, $runArray[$z][1], 1)
    _GUICtrlListView_AddSubItem($hListView, $z, $runArray[$z][2], 2)
    _GUICtrlListView_AddSubItem($hListView, $z, $runArray[$z][3], 3)

    If $runArray[$z][7] = True Then
        _GUICtrlListView_SetItemChecked($hListView, $z, $runArray[$z][7])       ; - Sets items to 'Checked' or 'Unchecked'.
    EndIf
Next

Any thoughts on if coloring a row is do-able, or if there is another way to get at this?

Thanks!

Here a example based on BugFix (http://www.autoit.de/index.php?page=Thread&postID=173432#post173432)

To get different Colors you have to create a Inifile @ScriptDir & "\LV_Format.ini" Here an example-ini: LV_FormatINI.txt (you have to rename it)

autoBert - This is very helpful! I will need to spend some time discecting and applying it, but it in my initial testing, it appears that this will meet my needs! Sorry for the delay in responding; I was working on another task.

I need to move forward to complete coding - without row coloring - in this version to meet a release date, but I hope to come back to this next week.

Thank you very much,

Kind Regards
