GUIListViewEx - BugFix Version 6 Apr 24

[Melba23]

[BUGFIX VERSION] - 6 Apr 24

Fixed: UDF failed if header colours were initialised but not specifically set.

New UDF in the zip below.

--------------------------------------------------------------------------------------

Note: This is a new recoded and expanded version of my earlier UDF of the same name. If you move to this new version there might well be several script-breaking changes, particularly when setting which columns are to be editable. Please read the "Beginner's Guide" and look at the included example scripts to see where things have changed.

--------------------------------------------------------------------------------------

This UDF allows you to do much more with ListView controls (either native or UDF created):

• Edit the content with plain text, combos or date-time pickers - and edit the headers too
• Move rows within the ListView
• Drag rows both within the ListView and to other ListViews in the same GUI (or not as required)
• Insert and delete columns and rows
• Sort columns by simply clicking the header
• Colour individual ListView items and headers
• Only select a single cell rather then the entire row
• Save and load entire ListViews

For the advanced user: If you use certain Windows message handlers (In particular WM_NOTIFY) in your script, please read the function headers for the equivalent handlers within the UDF.

Here is the UDF, with 6 examples and the guide, in zip format: GUIListViewEx.zip

Issue in GLVEx_Example_1

Step to reproduce:

1. Run
2. Click "Edit Right 5,0"
3. Click "Edit Left Header 1"

Symptoms: after clicking "Edit Left Header 1" , ListView item is edited instead Header .

mLipok,

Oops - a hangover from testing. I will check the other examples too - thanks for the report.

[NEW VERSION] - 19 May 16

Added:

• Pressing {BackSpace} will open an item for editing if the selected item is editable.
• Column headers can now be edited using combos as well as simple text (see new _GUIListViewEx_LoadHdrData function) - Scriptbreaking change.
• Ability to sort columns programmatically via new _GUIListViewEx_SortCol function

Fixed: A couple of small bugs.

New zip containing new UDF and several example scripts in first post.

In: GLVEx_Example_3

When I want to drag single row from Left to Right, then this is imposible but: How I can get Error message about "Different Col Number" ?

When I use CTRL + Arrows , going to the right and Edit is jumping to the left . Why the same is not in relation Top<>Bottom 

When I click in a single cell  and type some data, and now I click to different cell , this new data is not saved.

Please provide option to change default {BackSpace} to any other combination for example '^{Insert}' .

in GLVEx_Example_4

Issue ??  :

Step to reproduce:

1. Run
2. in Right LV Move First Column "Peter" to second position > after "Paul".
3. in Left LV  Click  Cell [0,0] and change text to XXXXX
4. from Left LV  Move Row 0  to Row 0 in Right LV

Symptoms: Row is incorectly moved, Collums are inproper ordered, you can se that in Right LV   XXXXX text is in Cell [0,1]  instead [0,0].

Or this was your intention ?

 

---

In GLVEx_Example_5

Moving from "No delete & no drop"  >>>> "No external drag" - is awesome feature,
Why "No external drag" not allowing "Delete" ?
This two LV can be used as an Configuration Dialog when user can drag option from one LV to second LV.

mLipok,

Answers:

--  There is no "insert marker" in the right ListView when you drag items into it which indicates that the drag will not work. Look at Ex 5 to see how this works in more detail - you only get an "insert marker" when the drag/drop operation is permitted.

--  When I move the current edit cell using "Ctrl-arrow" it moves perfectly in all directions - I do not understand what behaviour you are trying to explain. The behaviour of the up/down and left/right movement of the cells is set by the $iEditMode parameter passed when you call _GUIListViewEx_EditOnClick in the idle loop - as explained in the function header:

; $iEditMode      Return after single edit - 0 (default)
;                 {TAB} and ctrl-arrow keys move to next item - 2-digit code (row mode/column mode)
;                     0 = Cannot move
;                     1 = Reaching edge terminates edit process
;                     2 = Reaching edge remains in place
;                     3 = Reaching edge loops to opposite edge

--  Clicking in another cell will abandon the edit unless you set the correct $iAdded mode when initialising the ListView. To allow clicking elsewhere and retaining the previous edit you need mode 4:

; $iAdded    - 0      - No added features (default).  To get added features add any of the following values
; [...]
;              + 4    - Edit continues within same ListView by triple mouse-click on editable column

So use this initialisation line in the example and it will retain the edit when you click elsewhere:

; Initiate GLVEx - no array passed - count parameter set - default insert mark colour (black) - drag image - continue edit on click
$iLV_Left_Index = _GUIListViewEx_Init($cListView_Left, $aLV_List_Left, 1, 0, True, 4)

-- I will look into how the user could choose another "start edit" key.

Typo

[mLipok]

Is there a way to use Edit with this UDF:

 

Is there a way to change Header text for example Summary = 150,00 £ 

?

 

[Melba23]

mLipok,

-- There is currently no way to incorporate that code into the UDF to deal with the user input as it is entered. But as explained in the Guide, following an edit _GUIListViewEx_EditOnClick returns an array showing the previous and new content of any edited cells, so you can easily check whether the new content meets any particular criteria and reset the original content if it does not.

-- Again as explained in the Guide (you did read it before posting?) header content can be altered either by using Ctrl-click on the header (assuming you have correctly initiated the ListView - look at the $iAdded parameter again) or programmatically via _GUIListViewEx_EditHeader (you did look at the #CURRENT# function list?). If you use the _GUIListViewEx_LoadHdrData function you can even create a combo to edit the header.

Once. I think it's time to read it a few more times

 

[Melba23]

mLipok,

Good idea!

M23

[Melba23]

mLipok,

Try this Beta: <snip>

Look for the _GUIListViewEx_SetEditKey function:

; Syntax.........: _GUIListViewEx_SetEditKey($sKey)
; Parameters ....: $sKey - String of key(s): Up to 2 modifers (^ = Ctrl, ! = Alt) plus main key code as _IsPressed

So

_GUIListViewEx_SetEditKey("^2D")

will set Ctrl-Insert as you requested above.

Beta code removed

[Melba23]

mLipok,

I have just seen your edits above:

-- Ex 4: That is a Windows "feature" and nothing to do with my UDF. When you rearrange the headers, Windows keeps track of which is which - you use _GUICtrlListView_GetColumnOrder to find out the current order. When you drop a row into another ListView, Windows automatically places the content of each column in the "correct" column, as in the case you specify.

-- Ex 5: Explain exactly what you want to happen when dragging between the two ListViews.

Almost perfect, as there is some small issue with first use.
Step to reproduce:

1. Run example 3
2. Click Left ListView
3. press  Ctrl-Insert

Symptoms:
Focus is moved to RowMode Combobox instead entering in edit mode for selected Row.
Remark:
If I click again in LV thent this feature works correctly.

mLipok,

I cannot reproduce that - as long as I have an item selected in the left ListView it opens for editing when the HotKey is pressed.

M23

[mLipok]

I modify example 3 by adding this two additional lines:

; Create Left ListView
GUICtrlCreateLabel("Native ListView", 10, 5, 300, 35)
$cListView_Left = GUICtrlCreateListView("Tom|Dick|Harry", 10, 40, 300, 300, $LVS_SINGLESEL)
_GUICtrlListView_SetExtendedListViewStyle($cListView_Left, $LVS_EX_FULLROWSELECT)
_GUICtrlListView_SetColumnWidth($cListView_Left, 0, 93)
_GUICtrlListView_SetColumnWidth($cListView_Left, 1, 93)
_GUICtrlListView_SetColumnWidth($cListView_Left, 2, 93)
_GUICtrlListView_SetInsertMarkColor($cListView_Left, 0)
_GUIListViewEx_SetEditKey("^2D")
MsgBox(0, '', @error)

If I comment this :

#cs
    MsgBox(0, "Active ListView", $sMsg)

    MsgBox(0, "Info", "The Left ListView has 20 empty rows" & @CRLF & "each of 3 cells which can be edited" & @CRLF & _
    "Use Ctrl-arrow to move edit from cell to cell" & @CRLF & "<--------------------------")

#CE

All works OK.

This issue is fully reproducible on my Win10 x64

[Melba23]

mLipok,

My Win7 x32 does not show anything of the sort - we need another tester.

"D:\Scripts\Includes\GUIListViewEx.au3" (4163) : ==> Variable used without being declared.:
$iOldESC = Opt("GUICloseOnESC", 0)

$iOldESC not declared in __GUIListViewEx_EditProcess?

dmob,

Sorry about that - it will be declared in the next release.
