xbrowse - inline editing

[Otto]

Dear Mr. Rao,
is there a way to open die combobox with larger high to show more items.

Thank you in advance
Otto

Sorry.

Dear Mr. Rao,
is it possible to define Listbox object for editing as a member of the parent window of xBrowse and set height.
Thank you in advance
Otto

Suggest you create a dialog with listbox and trigger it with EDIT_BUTTON
I will soon post a small sample

[Otto]

Dear Mr. Rao,
can you please help me to understand why oDlgParent:nTop is 0 if I use ACTIVATE DIALOG oDlg CENTERED and why it does not change if I move the DIALOG.
What command do I need to refresh the values.
Thank you in advance
Otto

Please try this sample:

Code: Select all  Expand view  RUN

#include "fivewin.ch"

function Main()

   local oDlg, oBrw, oFont
   local aData := Array( 12 )

   AEval( aData, { |u,i| aData[ i ] := { i, Str( i, 2 ), NTOCMONTH( i ) } } )

      AUTOCOLS ;
      CELL LINES NOBORDER

   WITH OBJECT oBrw
      WITH OBJECT :aCols[ 3 ]
         :nEditType     := EDIT_BUTTON
         :bEditBlock    := { | nRow, nCol, oCol, nKey | MyBtnDialog( nRow, nCol, oCol, nKey ) }
      END
      :CreateFromCode()
   END

   ACTIVATE DIALOG oDlg CENTERED
   RELEASE FONT oFont

return nil

function MyBtnDialog( nRow, nCol, oCol, nKey )

   local cRet
   local oDlg, oLbx, oFont, aItems := Array( 12 )
   local cItem

   AEval( aItems, { |u,i| aItems[ i ] := NTOCMONTH( i ) } )
   cItem    := oCol:Value

   DEFINE FONT oFont NAME "VERDANA" SIZE 0,-16
   DEFINE DIALOG oDlg SIZE 150,220 PIXEL TRUEPIXEL FONT oFont

   @ 0,0 LISTBOX oLbx VAR cItem ITEMS aItems ;
      SIZE 150,185 PIXEL OF oDlg


   @ 190,10 BUTTON "OK" SIZE 40,20 PIXEL OF oDlg ACTION ( cRet := cItem, oDlg:End() )
   @ 190,60 BUTTON "CANCEL" SIZE 80,20 PIXEL OF oDlg ACTION oDlg:End()

   ACTIVATE DIALOG oDlg ;
      ON INIT oCol:AnchorToCell( oDlg )

   RELEASE FONT oFont

return cRet
 

Use the method oCol:AnchorToCell( oDlg ) to correctly position the dialog.

Dear Mr. Rao,
thank you I will try. But would you be so kind to tell me what I am missing with oDlgParent:nTop is 0 if I use ACTIVATE DIALOG oDlg CENTERED and why it does not change if I move the DIALOG.
Thank you in advance
Otto

nTop and nLeft of a dialog are always relative to the screen. Even if we specify a parent window/dialog, still these coordinates are relative to screen and not relative to the parent window/dialog.

So, you need to convert "nRow" to screen coordinates.

Here is an amended version of the ShowCombo function.

Code: Select all  Expand view  RUN

function showCombo( oBrw ,oDlgParent)

   local oDlg, cCombo := "2"
   local aItems := { "1", "2", "3" }
   local nRow := 0
//   local aRect    := GetClientRect( oDlgParent:hWnd )
   local aPoint := {}
//   local nCol := 100
   *----------------------------------------------------------
/*
   xbrowse( oDlgParent )
   nRow := ( oBrw:nRowSel * oBrw:nRowHeight ) + oBrw:HeaderHeight( .t. ) - 1
   aPoint      := ClientToClient( oDlgParent:hWnd, oBrw:hWnd, { nRow, nCol } )
   xbrowse( aPoint )
*/
   nRow := ( oBrw:nRowSel * oBrw:nRowHeight ) + oBrw:HeaderHeight( .t. ) - 1

   aPoint := ClientToScreen( oBrw:hWnd, { nRow, oBrw:SelectedCol():nDisplayCol } )

/*
   DEFINE DIALOG oDlg ;
      TITLE "Test" + str(nRow) ;
      FROM nRow, 300 ;
      TO nRow + 100, 400 + 6 ;
      PIXEL ;
      STYLE nOr( DS_MODALFRAME, WS_POPUP ) ;
      OF oDlgParent
*/
   DEFINE DIALOG oDlg TITLE "Test" SIZE 220,100 PIXEL TRUEPIXEL

   @ 2, 2 COMBOBOX cCombo ITEMS aItems SIZE 200, 100

   ACTIVATE DIALOG oDlg ON INIT oDlg:Move( aPoint[ 1 ], aPoint[ 2 ] )

return nil

Dear Mr. Rao,
thank you.
I mean why is ? oDlgParent:nTop if I send the DIALOG oDlg to the function always 0.
Best regards
Otto

First call oDlgParent:CoorsUpdate()
and then check nTop, nLeft, nBottom, nRight
