tScrollPanel and Pelles C

[damianodec]

Hi,
In FWH Samples there is dialogscroll.prg for tScrollPanel example but I need to use tScrollPanel inside dialog in my resource file (myrc.res)

how can I to create a dialog with tScrollPanel by Pelles C and then use it by REDEFINE DIALOG inside .prg?

thank you

[Antonio Linares]

Damiano,

In your RC include it this way:
CONTROL "", 101, "TScrollPanel", 0 | WS_CHILD | WS_VISIBLE | WS_TABSTOP, 10, 10, 200, 200

From the PRG:
oSPanel := TScrollPanel():Redefine( 101, 10, 10, 200, 200, oDlg )

hi Antonio,
thisi is dialog in Pelles C


this is my sample code:

Code: Select all | Expand

function EditDialog( oRec )

   local oDlg, oFont, oBold, oPanel
   local lNew  := ( oRec:RecNo == 0 )

   DEFINE FONT oFont NAME "TAHOMA" SIZE 0,-14
   DEFINE FONT oBold NAME "TAHOMA" SIZE 0,-14 BOLD

    DEFINE DIALOG oDlg RESOURCE "SCROOL" FONT oFont;
      TITLE "FWH TScrollPanel"

   //
   oPanel   := TScrollPanel():Redefine( 101, 10, 10, 200, 200, oDlg)
   oPanel:SetFont( oDlg:oFont )
   //


   ACTIVATE DIALOG oDlg CENTERED ON INIT ( PlaceControls( oPanel, oRec ) ) ;
      ON PAINT oDlg:Box( 59, 19, 302, 490 )

   RELEASE FONT oFont, oBold

return nil
 

this is the error log:

My mistake, you have to call it this way:

// Class TPanel Method Redefine( nId, oWnd, lDesign, cVarName, lBorder )

oPanel := TScrollPanel():Redefine( 101, oDlg )

Also, you have to call oPanel:SetFont( oDlg:oFont ) from the ON INIT clause of the ACTIVATE DIALOG

hi Antonio,
thank you.

Now I have another error.
I'm try to modify dialogscroll.prg in samples folder and I added another editdialog(oRec) istruction:

Code: Select all | Expand

//----------------------------------------------------------------------------//

function Main()

   local oRec

   SetGetColorFocus()
   SET DATE ITALIAN
   SET CENTURY ON
   RDDSETDEFAULT( "DBFCDX" )

   USE CUSTOMER NEW SHARED
   GOTO 10 // any record to be edited

   oRec  := TDataRow():New( "CUSTOMER" )

   EditDialog( oRec )
   EditDialog( oRec ) // <-------------- ADDED ROW
   CLOSE DATA

return nil

function EditDialog( oRec )

   local oDlg, oFont, oBold, oPanel
   local lNew  := ( oRec:RecNo == 0 )

   DEFINE FONT oFont NAME "TAHOMA" SIZE 0,-14
   DEFINE FONT oBold NAME "TAHOMA" SIZE 0,-14 BOLD

   DEFINE DIALOG oDlg SIZE 500,400 PIXEL TRUEPIXEL FONT oFont ;
...
 

when I close the first editdialog and start the second I get this error:

thank for your help.

Damiano,

Please post the complete code for function EditDialog( oRec )

It seems as oDlg:oBrush has been changed to nil

This little example works fine here, thats why I need to review your code:

Code: Select all | Expand

#include "FiveWin.ch"

function Main()

   Dialog()
   Dialog()

return nil

function Dialog()

   local oDlg

   DEFINE DIALOG oDlg

   ACTIVATE DIALOG oDlg CENTERED

return nil
