musicstashall Posted March 15, 2021 Share Posted March 15, 2021 Is it possible to increase the height of the item in this drawing option? I thought that this way you can draw multi-line items. Link to comment Share on other sites More sharing options...
LarsJ Posted March 16, 2021 Author Share Posted March 16, 2021 An owner drawn listview supports multi-line items through the LVS_OWNERDRAWFIXED style. FIXED means that it's only possible to set a certain height for all listview items. This common height is set during creation of the listview. You probably want to set individual heights for each listview item. But this is simply not possible for a standard listview control available in AutoIt. But other controls supports individual heights on a per-item basis. These are comboboxes and listboxes through the CBS_OWNERDRAWVARIABLE and LBS_OWNERDRAWVARIABLE styles, respectively. VARIABLE means that you can set individual heights on a per-item basis. If you want to use individual item heights then the only option is to rewrite the code to support e.g. a listbox control. But it'll complicate the owner draw code for multi-line items in that you'll need multiple text rectangles in the same listbox item corresponding to each subline. A simpler solution to the problem could be to simulate multi-line listview items using one listview item for each subline. This could be done by simply adding an additional listview column with item numbers as shown in the figure: For multi-line items, the item number is only filled in for the first subline. The advantage of this approach is that all existing owner draw code can be reused. You probably still need additional code to handle the multi-line items depending on what functionality you want. But this can in all likelihood be done through an array index to keep track of these multi-line items. I've made a note about simulating multi-line listview items in this way because it might be interesting to investigate the technique. So I might be able to help with some code. But it probably won’t be until the Easter holidays. musicstashall 1 Controls,  File Explorer,  ROT objects,  UI Automation,  Windows Message MonitorCompiled code: Accessing AutoIt variables,  DotNet.au3 UDF,  Using C# and VB codeShell menus: The Context menu,  The Favorites menu. Shell related: Control Panel,  System Image ListsGraphics related: Rubik's Cube,  OpenGL without external libraries,  Navigating in an image,  Non-rectangular selectionsListView controls: Colors and fonts,  Multi-line header,  Multi-line items,  Checkboxes and icons,  Incremental searchListView controls: Virtual ListViews,  Editing cells,  Data display functions Link to comment Share on other sites More sharing options...

Thank you for your answer. Rather, this option will not suit me. But I implemented multiline items in a different your example, but I had to abandon the LVS_OWNERDRAWFIXED style.

Thank you. Hi Lion66 With the help of LarsJ's function WM_DRAWITEM in this post, I could combine my last script ("2h") and his function WM_DRAWITEM to display partially colored items (incremental search) in an owner drawn ListView. Here is what it looks like : Changing the search column can be done through the combo control or via a right-click on a column header. Columns sorting indexes on full array are created when user left-click a column header, then they are preserved until the script ends. Temporary column indexes on sub array (i.e corresponding to one search) are created the same way (when user left-click on a column header) and they are preserved until the next search etc... all this already existed in preceding version "2h" The script seems to work though some parts are missing (no hook and no Func WM_ACTIVATE, $fListViewHasFocus forced to 1) . Even with these missing parts, it worked for me without any crash. Concerning your "script crash" dated July 2019 in this post (of the present thread) I hope you found the solution as you needed the non-sensitive mode. We'll talk about it if it's not solved as it worked for me after adding "(?i)" in both RegEx parts (you will see that in the script below too) Meanwhile, could you please try this script "2i" and let's hope all will be good. expandcollapse popup#include <ComboConstants.au3> #include <EditConstants.au3> #include <GuiListView.au3> #include <GUIConstantsEx.au3> #include <StaticConstants.au3> #include <WindowsConstants.au3> #include "RandomArray.au3" ; LarsJ #include "DrawItem.au3" ; " Opt("MustDeclareVars", 1) Global $g_iRows = 1000, $g_iCols = 6, $g_iLeftLV = 10, $g_iTopLV = 40, $g_hGui, $g_hListView, $g_hHeader, $g_hEdit Global $g_aCols = ["Strings", "Integers", "Floats", "Dates", "Times", "R/C"], $g_aWidths = [230, 61, 124, 70, 60, 60] Global $g_idListView, $g_idMarker, $g_idComboCol, $g_idComboColDummy, $g_idEditDummy Global $g_sSearch, $g_iSearchCol, $g_iSortDir, $g_iSearch = $g_iRows Global $g_aArray, $g_aSubArray, $g_tDefaultIndex, $g_tIndex = DllStructCreate("uint arr[" & $g_iRows & "]") Global $g_aIndex[$g_iCols], $g_aIndexTemp[$g_iCols] ; VarGetType's : $g_aIndex => "Array", $g_aIndex[0] => "String" Global $fListViewHasFocus = 1 ; trying this for now, we'll see...

LarsJ will surely have the correct answer Edit 2 (a few hours after) : I just digged a bit into these different codes. This bad behavior seems to happen when the LV got a $LVS_OWNERDATA style but $LVN_GETDISPINFOW isn't used in the script. Then a double click on any header separator reduces immediately the column width to nearly 0 . It's just an hypothesis, we'll see if it's confirmed or refuted. The script above has just been updated to prevent this bad behavior of $HDN_DIVIDERDBLCLICKW (i.e. after a double-click on a header separator, the column will now retrieve its original size, which is better than a 0 width column) Edit 3 : Update May 26th, 2021 Fixed the search issue discussed in this post Edited May 26, 2021 by pixelsearch Update May 26th, 2021 Lion66 1 Link to comment Share on other sites More sharing options...

I would like to add that even when the LV is created with a LVS_OWNERDATA style (virtual LV), then a HDN_DIVIDERDBLCLICK notification will retrieve correct informations about the column width if LVN_GETDISPINFOW is used to set the text. In this case, a double click on a header separator will behave nicely again (this is the case in my preceding script "2h") On 12/7/2015 at 5:33 PM, LarsJ said: (A custom drawn listview supports coloring of fields. However, the coloring works best for whole fields. This doesn't make it applicable to incremental search.) I would like to ask. When you write that "the custom drawn [NM_CUSTOMDRAW] works best for whole fields", you don't definitely say that it doesn't work at all for partial fields. Do you think it would be possible to try it on an incremental search, or there is absolutely no way that it will work ? Thanks.

Lion66 Posted May 11, 2021 Share Posted May 11, 2021 (edited) Hi pixelsearch. You as always on top! Thank you for puzzled and answered. I have not had time yet to see the code. I'm wondering to dig and learn. But I fear it to use it in my scripts, because I do not understand much, and if necessary, i cant to make changes. The solution with the insensitive search mode present is also in your examples and work good. The only thing I noticed in version 2i: when you click on the separator between the first two columns, in the second column, the partial date of the first is displayed on the left.  Edited May 11, 2021 by Lion66 Link to comment Share on other sites More sharing options...

Hi Lion66 Really the one "on top" is LarsJ. Without his persuasion, detailed explanations and incredible examples, I would never have tried any Virtual listview. Now I like them ! Concerning version "2i" above and its overlapping data from 1 column in the other (when you resize columns), I noticed it too but I got no idea how to fix this (some refresh works but partially) Is there a way to fix this when the items are displayed via WM_DRAWITEM in an owner drawn Virtual ListView ? Let's hope anyone who reads this will have the answer to that question. 5 hours ago, Lion66 said: I'm wondering to dig and learn. But I fear it to use it in my scripts, because I do not understand much, and if necessary, i cant to make changes. There's nothing to be afraid of. Just try a simple script with a single column (at least nothing will overlap) a few rows and no sorting. Maybe the non-coloured script "2h" would be a good choice too (as it doesn't use the complicated WM_DRAWITEM notification) . When you're confident with the result, then you can add some functionalities. And if you find problems in your script, there always will be nice people on this Forum to help, after you show them what you scripted. Good luck Link to comment Share on other sites More sharing options...

Do you think it would be possible to try it on an incremental search, or there is absolutely no way that it will work ? It can probably easily be done. But because custom draw code is extremely message intensive, you really need to pay attention to the performance of your code. The technique is basically the same as for the owner draw code. Also in the custom draw code you use GDI functions to draw the different visual elements. When using GDI functions in custom draw code, the functions must be performed in the postpaint drawing stage i.e. after all default drawing is done. I think the code in the "Too much code" section here contains all the information you need.  A workaround for all these HDN_DIVIDERDBLCLICK issues is to set correct column widths from the start, and then disable column resize through dragging/double-clicking header dividers by adding the HDS_NOSIZING style to the header control. pixelsearch 1 Controls,  File Explorer,  ROT objects,  UI Automation,  Windows Message MonitorCompiled code: Accessing AutoIt variables,  DotNet.au3 UDF,  Using C# and VB codeShell menus: The Context menu,  The Favorites menu. Shell related: Control Panel,  System Image ListsGraphics related: Rubik's Cube,  OpenGL without external libraries,  Navigating in an image,  Non-rectangular selectionsListView controls: Colors and fonts,  Multi-line header,  Multi-line items,  Checkboxes and icons,  Incremental searchListView controls: Virtual ListViews,  Editing cells,  Data display functions Link to comment Share on other sites More sharing options...

As I understand it, a daughter window with a new header is superimposed on the header of Listview. But then for the sort function I need to handle this new header in the WM_Notify. Or I can somehow add a HDS_NOSIZING style to the header of the existing ListView? Link to comment Share on other sites More sharing options...

pixelsearch Posted May 18, 2021 Share Posted May 18, 2021 (edited) Hi LarsJ I tried to use the Custom draw for incremental search but it didn't work fine, could you please help ? The only thing that "works" in the script below (named "2k") is this : * Please type . or .$ in the Search field, then hover over rows and you'll see the correct matching 1st (or last) character with cyan background in Col 0. Nothing appears if the rows aren't hovered over. * Then change the search column (right-click on a new header or use the Combo) and the cyan background never appears in any searched column (it should appear on 1st or last character, no matter the searched column, as RegEx search is "." or ".$") I checked the 4 values of the rectangle etc... and added some commented ConsoleWrite's during Case $NM_CUSTOMDRAW. Values seem correct, maybe hdc isn't correct when applied to Cols 1+ ? I didn't use at all "clrTextBk" or "clrText". Their value is constantly 0xFF000000 ($CLR_DEFAULT) and if we're able to see a cyan background on matched characters while hovering over Col 0, then it should be ok. Also, as soon as I tried to use "clrTextBk" during a test, then the whole subitem got its background colored. Finally, as the Owner draw script ("2i") worked fine in a precedent post , then we don't really need the Custom draw way (especially it's "extremely message intensive" as you indicated) , but I was just curious to see if it was doable or not. Thanks if you got any idea on how to make Case $NM_CUSTOMDRAW work correctly in the script : expandcollapse popup#include <ComboConstants.au3> #include <EditConstants.au3> #include <GuiListView.au3> #include <GUIConstantsEx.au3> #include <StaticConstants.au3> #include <WindowsConstants.au3> #include "RandomArray.au3" ; LarsJ Opt("MustDeclareVars", 1) Global $g_iRows = 1000, $g_iCols = 6, $g_iLeftLV = 10, $g_iTopLV = 40, $g_hGui, $g_hListView, $g_hHeader, $g_hEdit Global $g_aCols = ["Strings", "Integers", "Floats", "Dates", "Times", "R/C"], $g_aWidths = [230, 61, 124, 70, 60, 60] Global $g_idListView, $g_idMarker, $g_idComboCol, $g_idComboColDummy, $g_idEditDummy Global $g_sSearch, $g_iSearchCol, $g_iSortDir, $g_iSearch = $g_iRows Global $g_aArray, $g_aSubArray, $g_tDefaultIndex, $g_tIndex = DllStructCreate("uint arr[" & $g_iRows & "]") Global $g_aIndex[$g_iCols], $g_aIndexTemp[$g_iCols] ; VarGetType's : $g_aIndex => "Array", $g_aIndex[0] => "String" Example() Func Example() ; Generate array & one index _Generate_All($g_aArray) $g_aSubArray = $g_aArray $g_tDefaultIndex = $g_tIndex ; Create GUI $g_hGui = GUICreate("Virtual ListView + Sort + Incremental search + CustomDraw (2k)", 630 + 20, 788 + 30 + 20) ; Create Edit control (search) + dummy control Local $idEdit = GUICtrlCreateEdit("", 120, 10, 305, 20, BitXOR($GUI_SS_DEFAULT_EDIT, $WS_HSCROLL, $WS_VSCROLL)) $g_hEdit = GUICtrlGetHandle($idEdit) $g_idEditDummy = GUICtrlCreateDummy() ; Create ComboBox control (how to search : RegEx or Normal ?)

Lion66 Posted May 20, 2021 Share Posted May 20, 2021 I noticed that when using the $LVS_OWNERDRAWFIXED style, the standard functions stop working. Such as the: _GUICtrlListView_JustifyColumn _GUICtrlListView_GetItemText Possibly a finished version "2k" will solve that. Or how to solve this in early version "2i" ?

pixelsearch Posted May 20, 2021 Share Posted May 20, 2021 (edited) Hi Lion66 * Concerning _GUICtrlListView_GetItemText (LVM_GETITEMTEXT message) it doesn't work in a Virtual Listview (LVS_OWNERDATA style) as stipulated in this MS link (just search LVM_GETITEMTEXT in the web page, it will lead you to 4 chapters concerning Virtual Listview, all interesting to read) Edit #1 : _GUICtrlListView_GetItemText seems to work fine if LVN_GETDISPINFO is used (just tested on "2h") * Concerning _GUICtrlListView_JustifyColumn (LVM_SETCOLUMN message) I think you're right. It works fine when the Virtual ListView is populated via LVN_GETDISPINFO, but when it's populated via WM_DRAWITEM (when LV got the LVS_OWNERDRAWFIXED style) then it doesn't work because coords applied by user's code in WM_DRAWITEM are all related to a left string justification. Here is a silly test to show what could work. In version "2i", you can add 1 line to center headers : For $i = 0 To $g_iCols - 1 _GUICtrlListView_AddColumn($g_idListView, $g_aCols[$i], $g_aWidths[$i]) _GUICtrlListView_JustifyColumn($g_idListView, $i, 2) ; <======= added line Next Then you can center all items (starting from col 1 in the example below, by modifying 1 line : ; DllCall( "user32.dll", "int", "DrawTextW", "handle", $hDC, "wstr", $sItemText, "int", StringLen( $sItemText ), "struct*", $tRect, "uint", 0) ; _WinAPI_DrawText changed to : DllCall( "user32.dll", "int", "DrawTextW", "handle", $hDC, "wstr", $sItemText, "int", StringLen( $sItemText ), "struct*", $tRect, "uint", $i > 0 ? $DT_CENTER : 0) ; _WinAPI_DrawText Unfortunately it's not enough : what looks great in the precedent pic (all cols centered starting from col 1+) will display bad coords when search (a "." in search field) is applied to other columns, for example : Maybe if we knew how to change the matched rectangle coords, then center justification could be done when using WM_DRAWITEM ? Edit #2 : @Lion66 To retrieve the text of any subitem in a virtual listview having LVS_OWNERDRAWFIXED style, you need to retrieve it from the array that populated the listview. As you can't use _GUICtrlListView_GetItemText, then try this code in "2i", it will give you an idea on how to retrieve subitem texts in your script.

Lion66 Posted May 20, 2021 Share Posted May 20, 2021 The second question is solved, the first is not. It's Complicated. Tomorrow will need something else, and again It will be necessary ask for help on the forum. I hope that you will be able to solve the version "2k", and there will be no such problems in it.

In the custom draw code, only the column provided with a search filter is drawn with GDI functions. Otherwise, all columns are drawn with default code in the Windows dll-files at the speed of real compiled code. This also applies when there is no search filter. In the owner draw code, all columns are drawn with GDI functions. It ends up being quite a lot of code that's executed as pure interpreted AutoIt code. In an example like this, it's a really good idea to use custom draw code. The code has been tested on Windows 7. From Windows 7 and newer Windows versions, the subitem rectangles appear to be implemented in a consistent manner. But this isn't the case on older Windows versions. Eg. on Windows XP, the size and location of subitem rectangles may vary by a few pixels. An example is seen in Multi-line ListView items (search for Windows XP).
