combobox color

[Silvio.Falconi]

I have a combobox

@ 10, 120 COMBOBOX aget[1] VAR cCategoria Items ArrTranspose(aCategorie )[ 2] size 200,90 PIXEL OF oDlg


on first element of aCategorie there is "nessuna" and the last item is "Aggiungi"

I wish change color and font of text only on these two items

[Jimmy]

hi Silvio,

as i can say a normal Combobox can only change Color for all Items
to change it for special Item you need Ownerdraw.

i know that Fivewin have

Code: Select all  Expand view  RUN

ON DRAWITEM

but i have not find out how it work so i wrote my own Method

here a CODE snip which i use

Code: Select all  Expand view  RUN

oCombo_left:bOwnerDraw := { | a, b, c, d | oExpl_Left:DoMyComBo( a, b, c, d, @acItem, @acType, @acBitmaps, oCombo_left ) }

Hello,
We use combobox with bitmaps.
Best regards,
Otto



Now with WEBVIEW2 or mod harbour, these things are easily done.

hi Silvio.

We use combobox with bitmaps.

Solution from Otto, using colored Bitmap, seems me a easy Solution

Perhaps you not understood my problem , please ready my message please I not Wish bitmap i Wish colorize only the text of item , i not want list of colors, i Wish only colorize the First item text and the last item text

this is the source

AAdd( ademo, {"00000","Nessuna"} )
DO WHILE !oDbf:Eof()
AAdd( ademo, {oDbf:Cod,TRIM(oDbf:DESC)} )
oDbf:Skip()
ENDDO
AAdd( ademo, {"00000","Aggiungi"} )


I wish only "Nessuna" and "Aggiungi" with another color more clear

I do understand your Problem, but do you understand Ownerdraw ?
it is much more complicate than using a bitmap to mark a Item in Combobox or LIstbox using different Font and Color

[Otto]

Dear Jimmy,

I think using TComboMetro and changing the Paint method would be an option.

Best regards,
Otto

Code: Select all  Expand view  RUN

METHOD Paint() CLASS TComboMetro

   local aInfo, aRect, hBrush
   local nBtnTop, nBtnLeft

   aInfo    := ::DispBegin()

   aRect    := GetClientRect( ::hWnd )

   if GetFocus() == ::hWnd
      hBrush   := CreateSolidBrush( TGet():nClrFocus )
      FillRect( ::hDC, aRect, hBrush )
      DeleteObject( hBrush )
      FillRect( ::hDC, { aRect[ 1 ], aRect[ 4 ] - ::nHeight, aRect[ 3 ], aRect[ 4 ] }, ::oBrush:hBrush )
   else
      FillRect( ::hDC, aRect, ::oBrush:hBrush )
   endif

   WndBox2007( ::hDC, aRect[ 1 ], aRect[ 2 ], aRect[ 3 ] - 1, aRect[ 4 ] - 1, ::nClrBorder )
   nBtnTop     := Int( ( aRect[ 1 ] + aRect[ 3 ] ) / 2 - 0 )
   nBtnLeft    := Int( aRect[ 4 ] - ::nHeight / 2 - 5 )

   MoveTo( ::hDC, nBtnLeft,      nBtnTop )
   LineTo( ::hDC, nBtnLeft + 5,  nBtnTop + 5, ::hPenButton )
   LineTo( ::hDC, nBtnLeft + 10, nBtnTop,     ::hPenButton )

   aRect[ 4 ]  -= aRect[ 3 ]
   aRect[ 2 ]  += 12
   aRect[ 4 ]  -= 2

   ::oFont:Activate( ::hDC )
   SetTextColor( ::hDC, CLR_BLACK )
   aRect[ 3 ]  -= 1
   DrawTextTransparent( ::hDC, ::aItems[ ::nAt ], aRect, DT_VCENTER + DT_SINGLELINE )
   ::oFont:DeActivate( ::hDC )

   ::DispEnd( aInfo )

return nil

[Otto]

Dear Jimmy,
nevertheless, I think that the future for the frontend will be HTML (WEBVIEW2)

Otto

Hello,
In my case, I use the HARBOURINO preprocessor and patcher, so the source code for the combobox would look like this.

And here are the files that Harbourino needs:
Best regards,

[Silvio.Falconi]

don't teach me HTML or php or asp.net because I have thirty years of experience in HTML because I teachl it at school HTML+CSS, don't be a professor with me


It doesn't suit you.


I asked how it was done in Windows fwh +harbour

[Otto]

Have you tried TComboMetro?

[Jimmy]

hi Otto,

Have you tried TComboMetro?

how to identify which Item is active to draw when not have itemID of DRAWITEMSTRUCT structure
https://learn.microsoft.com/en-us/windows/win32/api/winuser/ns-winuser-drawitemstruct

METHOD Paint() CLASS TComboMetro does not have any itemID to identify it

[Otto]

Dear Jimmy,

In TComboMetro, the combobox is done with an xbrowse.

Maybe we could make aItems multidimensional and then pass the color along with it.
Or just pass another ARRAY with the colors. And then compare it in ::bClrStd.

::bClrStd := { || If( ::nArrayAt == ::nHoverAt .and. ::nArrayAt > ::nBlankRows, ;
{ CLR_WHITE, CLR_BLUE }, { CLR_BLACK, CLR_WHITE } ) }

Best regards,
Otto

i did not know that, so it should be easy when is based on xbrowse
