Hi guys
how to embed a button inside a syslistview (that is inside a dialog and now windows form) ?
I found a code but it is in .Net and i couldn´t be able to port it.
https://www.codeproject.com/Articles/9188/Embedding-Controls-in-a-ListView
Since i wasn´t able to port, i then tried to convert a checkbox inside the syslistcontrol onto a normal button, by retrieving the handle of that checkbox, but also returned zero.
So, i have 2 questions....Can this .Net be ported ?
And if not...
How to retrieve the hanndle of a check box existent inside a certain item and subitem os a syslistvioew control existent in a dialogbox ?
I made this o try o retrieve the handle, but it keeps returning zero.
call GetCheckboxHandleInListView D@hList, 1, 3
Proc GetCheckboxHandleInListView:
Arguments @hList, @RowIndex, @ColumnIndex
Local @CheckBoxX, @CheckBoxY
Structure @SubitemRect 24, @SubitemRect.leftDis 0, @SubitemRect.topDis 4, @SubitemRect.rightDis 8, @SubitemRect.bottomDis 12,
@SubitemRect.PointXDis 16, @SubitemRect.PointYDis 20
Uses ecx, edx
; Calculate the position of the checkbox within the subitem's rectangle
;int checkboxX = itemRect.left + columnIndex * 20; // Adjust as needed
;int checkboxY = itemRect.top + (itemRect.bottom - itemRect.top) / 2;
call ListView_GetSubItemRect D@hList, D@RowIndex, D@ColumnIndex, &LVIR_BOUNDS, D@SubitemRect
; Calculate the position of the checkbox within the item's rectangle
lea ecx D@SubitemRect.PointXDis
mov eax D@SubitemRect.leftDis | mov D$ecx eax;mov D@CheckBoxX eax
mov eax D@SubitemRect.bottomDis | sub eax D@SubitemRect.topDis | shr eax 1 | add eax D@SubitemRect.topDis | mov D$ecx+4 eax;mov D@CheckBoxY eax
; Get the handle of the child window (checkbox) at the specified position
call 'USER32.ScreenToClient' D@hList, ecx
lea ecx D@SubitemRect.PointXDis
call 'USER32.ChildWindowFromPoint' D@hList, ecx
EndP
Proc ListView_GetSubItemRect:
Arguments @hwnd, @iItem, @iSubItem, @code, @prc
Uses ecx, edx
mov eax D@prc
mov ecx D@code | mov D$eax+RECT.leftDis ecx
mov ecx D@iSubItem | mov D$eax+RECT.topDis ecx
mov D$eax+RECT.rightDis 0
mov D$eax+RECT.bottomDis 0
call 'USER32.SendMessageA' D@hwnd, &LVM_GETSUBITEMRECT, D@iItem, D@prc;((D@prc) ? ((((LPRECT)(D@prc))->top = D@iSubItem), (((LPRECT)(D@prc))->left = D@code), (LPARAM)(D@prc)) : (LPARAM)(LPRECT)NULL)
EndP
Is there a way to do it ? I mean, or directly creating a button isnide a syslistview control (at a speific row and col) or by retrieving the handle of a existent checkbox and then converting it onto a normal button (afterall, a checkbox is nothing but a button)
Btw...what i mean with a small button, is the same as the image below

I wanted to do as the image below. I suceeded to create a checkbox, but i wouuld like to add an extra button at the last column (and perhaps with a label too on the last column)
This buton wil be used to open the opendialog function to load a file and retrieve/fix a path to be displayed in the syslistview control on the item that is missing a path

Dunno if this'll help, as I've never tried embedding a button in a listview control (I assume that's what you mean when you say "inside a syslistview"?). I have, however, successfully embedded buttons in a listbox, like what you see here. I imagine this might well work with a listview as well.
This was very simple: I just got the screen client coordinates of the location in the listbox where I wanted the button, then sized and positioned a "floating" button accordingly (I made the button a child of the listbox). When I don't want the button to appear, I simply hide it.
Here's the same thing except with an embedded combobox within the listbox:

How you managed to do that small button ?
About the listbos too, pls.
I found one example of a combobox, but uses MFC - https://www.codeproject.com/Articles/5709/Customized-Report-List-Control-With-In-Place-Combo
What i mean with syslistview, is the syslistview32 class and not the regular listbox.

CreateWindowEx() (https://learn.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-createwindowexa?redirectedfrom=MSDN) is your friend here.
QuoteAbout the listbos too, pls.
Ditto for that. Any window you want.

I think you're confusing Microsoft's
class name for the control (which is "SysListView32") with its commonly-used name, which is
listview (as opposed to listbox, which is a much more primitive control).
Indeed, i confused. It´s listview and not listbox.
Btw....Tks for the tip. I managed to work
The button is not that pretty yet, but at least it´s there. :greenclp: :greenclp: :greenclp:

It´s a bit late right now. I´ll continue tomorrow. Tks a lot. It was really easy, and handy.
One question...is it affect flickering of the listview or problems of painting when you drag the columns etc ?

@Guga,
I'm curious to know how your project turned out. Did you get things all prettied up?
You might also want to take a look at DrawFrameControl() (https://learn.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-drawframecontrol), if you don't already know about it. This can draw several standard Windows gizmos, like scroll buttons and pushbuttons. That's what I used in my program to draw things.
Weird :rolleyes:
BOOL DrawFrameControl(
[in] HDC unnamedParam1,
[in] LPRECT unnamedParam2,
[in] UINT unnamedParam3,
[in] UINT unnamedParam4
Yes, weird: that's from the current version ("learn.microsoft.com ..."). I copied my help text from the earlier version ("MSDN"):
BOOL DrawFrameControl (
HDC hdc,
LPRECT lprc,
UINT uType,
UINT uState);
Guess the new version hides their identity to protect the innocent ...
Hi JJ, Hi NoCForme
Here´s the skeleton of the app (plus the dlls in case it is needed). It do have the button as you said, but have small issues when i drag the column Painting problem perhaps or adjustment of position making the button appear duuplicated sometimes.
I´ll try to fix it, but before i´m porting (well, trying to) the project TimoVJL showed. It´s really amazing, although it uses listbox and not syslistview control, but i guess it can be very usefull.
Btw...the button does nothign yet...just show up on the proper position. Well..untill when we start to drag the columns :biggrin: :biggrin: :biggrin: :biggrin:
On the src code (embedded in the file) i also adding some extra fucntions where i converted from C macros related to the controls. Things like ListBox_Dir, ListBox_GetCaretIndex, ListBox_GetSelCount etc. Those macros are the ones existent in windowsx.h. There are other macros too in CommCtrl.h from winSdk that should be excellent to port later. (It would be handy for Masm and also RosAsm)
A few examples of the converted C macros to RosAsm functions are:
; ListBox_InsertString(hwndCtl, index, lpsz)
Proc ListBox_InsertString:
Arguments @hwndCtl, @index, @lpsz
Uses ecx, edx
call 'USER32.SendMessageA', D@hwndCtl, &LB_INSERTSTRING, D@index, D@lpsz
EndP
; ListBox_AddItemData(hwndCtl, data)
Proc ListBox_AddItemData:
Arguments @hwndCtl, @data
Uses ecx, edx
call 'USER32.SendMessageA', D@hwndCtl, &LB_ADDSTRING, 0, D@data
EndP
; ListBox_InsertItemData(hwndCtl, index, data)
Proc ListBox_InsertItemData:
Arguments @hwndCtl, @index, @data
Uses ecx, edx
call 'USER32.SendMessageA', D@hwndCtl, &LB_INSERTSTRING, D@index, D@data
EndP
; ListBox_DeleteString(hwndCtl, index)
Proc ListBox_DeleteString:
Arguments @hwndCtl, @index
Uses ecx, edx
call 'USER32.SendMessageA', D@hwndCtl, &LB_DELETESTRING, D@index, 0
EndP
Shouldn´t be that hard port it to masm as well, since those macros are somewhat easier to read in C
Btw,...to add the btn to the syslist control i create a function like this:
Note: Don´t pay attention on the function name "GetCheckboxHandleInListView". It´s not a checkbox. I simply reused an old function i had named like that when i was testing to see if the button worked. I´ll rename it later.
Proc GetCheckboxHandleInListView:
Arguments @Adressee, @hList, @RowIndex, @ColumnIndex
Local @CheckBoxX, @CheckBoxY, @ButtonWidth, @ButtonHeight
Structure @SubitemRect 24, @SubitemRect.leftDis 0, @SubitemRect.topDis 4, @SubitemRect.rightDis 8, @SubitemRect.bottomDis 12,
@Button.PointXDis 16, @Button.PointYDis 20
Uses ecx, edx
; Get the item's rectangle
; call ListView_GetItemRect D@hList, D@RowIndex, D@itemRect, &LVIR_BOUNDS
; Calculate the position of the checkbox within the item's rectangle
;int checkboxX = itemRect.left + columnIndex * 20; // Adjust as needed
;int checkboxY = itemRect.top + (itemRect.bottom - itemRect.top) / 2;
call ListView_GetSubItemRect D@hList, D@RowIndex, D@ColumnIndex, &LVIR_BOUNDS, D@SubitemRect
mov eax D@SubitemRect.bottomDis | sub eax D@SubitemRect.topDis | mov D@ButtonHeight eax
mov D@ButtonWidth eax
; Calculate the position of the checkbox within the item's rectangle
lea ecx D@Button.PointXDis
mov eax D@SubitemRect.leftDis | mov D$ecx eax;mov D@CheckBoxX eax
mov eax D@SubitemRect.topDis | mov D$ecx+4 eax
;mov eax D@SubitemRect.bottomDis | sub eax D@SubitemRect.topDis | shr eax 1 | add eax D@SubitemRect.topDis | mov D$ecx+4 eax;mov D@CheckBoxY eax
; Get the handle of the child window (checkbox) at the specified position
call 'USER32.ChildWindowFromPoint' D@hList, ecx
call 'USER32.CreateWindowExA' 0, {B$ "BUTTON", 0}, {B$ "...", 0}, &WS_CHILD__&WS_VISIBLE__&BS_PUSHBUTTON__&BS_FLAT,
D@Button.PointXDis, D@Button.PointYDis, D@ButtonWidth, D@ButtonHeight,
D@hList, &NULL, &NULL, &NULL
; Set the ListView as the parent of the button
call 'USER32.SetParent' eax, D@hList
EndP
