Dear Roberto,

If you want to scroll the dialog contents in a TFolderEx control probably using a TScrollPanel is the way to go.

We are going to test it and share an example

Please wait for us, thank you

Antonio,
I did it!
As you suggest I used TScrollPanel to make folders scrollable and, with a few modifications in the container object to manage window and splitter resizing, now it works.
All the controls are now painted on the TScrollPanel instead of the FolderEx dialogs
Only, it would be nice to have horizontal scrollBars too...

here is the code I modified in the TFolderEx():New() method:

Code: Select all  Expand view

for n = 1 to nLen

    DEFINE DIALOG oDlg OF Self STYLE nOR( WS_CHILD, If( ! ::oWnd:IsKindOf( "TDIALOG"), WS_CLIPCHILDREN, 0 ) );
     FROM 0, 1 TO ::nHeight(), ::nWidth() PIXEL ;
     FONT ::ownd:oFont ;
     HELPID If( Len( ::aHelps ) >= n , ::aHelps[ n ] , NIL )
    #ifdef RECINFORMATICA                   // 06/09/2024
        default lHBar := .f.
        default lVBar := .f.
        if lVBar
            oPanel := TScrollPanel():New( 1, 1, ::nHeight()-30, ::nWidth()-30, oDlg, .T. )
            oPanel:SetColor( CLR_WHITE, nClrPane )
        endif
    #endif

      oDlg:SetBrush( ::oBrush )
      ::aDialogs[ n ] = oDlg

      oDlg:cVarName := "Page" + AllTrim( Str( n ) )
      oDlg:Hide()
      // oDlg:lTransparent := .T.

   next

 

How to get the actual window to put controls on:

Code: Select all  Expand view

Method GetWnd() CLASS CClip
local oWnd
if ::oFolder # NIL      // folder non ancora creato
    oWnd := if( ::lFolder, ::oFolder:aDialogs[::oFolder:nOption], ::oWnd )
    #ifdef SCROLLCLIP
        // add: 05/09/2024 gestione tScrollPanel() per <oClip>
        if ::lFolder .and. ::oFolder:isKindof("TFOLDEREX") .and. !empty(oWnd:aControls) .and. oWnd:aControls[1]:isKindof("TSCROLLPANEL")
            oWnd := oWnd:aControls[1]
        endif
    #endif
endif
Return (oWnd)

Excellent Roberto!

Class TScrollPanel needs to use WS_HSCROLL too and add an horizontal scrollbar:

DEFINE SCROLLBAR ::oVScroll VERTICAL OF Self RANGE 1,2
DEFINE SCROLLBAR ::oHScroll HORIZONTAL OF Self RANGE 1,2

You are very close to have it!

Antonio,
I already tried it but it seems that the ScrollPanel class has no methods to manage it:

Code: Select all  Expand view

for n = 1 to nLen

    DEFINE DIALOG oDlg OF Self STYLE nOR( WS_CHILD, If( ! ::oWnd:IsKindOf( "TDIALOG"), WS_CLIPCHILDREN, 0 ) );
     FROM 0, 1 TO ::nHeight(), ::nWidth() PIXEL ;
     FONT ::ownd:oFont ;
     HELPID If( Len( ::aHelps ) >= n , ::aHelps[ n ] , NIL )
    #ifdef RECINFORMATICA                   // 06/09/2024
        default lHBar := .f.
        default lVBar := .f.
        if lVBar .or. lHBar
            oPanel := TScrollPanel():New( 1, 1, ::nHeight()-30, ::nWidth()-30, oDlg, .T. )
            oPanel:SetColor( CLR_WHITE, nClrPane )
            // this does not work, they are not managed?
            if lHBar
                DEFINE SCROLLBAR oPanel:oHScroll HORIZONTAL OF oPanel RANGE 1,2
               
                oPanel:nStyle := nOr(  WS_CHILD, WS_VSCROLL, WS_HSCROLL,;
                                    WS_VISIBLE, WS_TABSTOP, WS_CLIPCHILDREN )
                oPanel:refresh()
            endif
            //
        endif
    #endif

      oDlg:SetBrush( ::oBrush )
      ::aDialogs[ n ] = oDlg

      oDlg:cVarName := "Page" + AllTrim( Str( n ) )
      oDlg:Hide()
      // oDlg:lTransparent := .T.

   next

 

where am I going wrong?
Do I have to write all the methods as for the vertical scrollbar?
regards

[Antonio Linares]

I am afraid yes as it never had support for horizontal scroll

[Silvio.Falconi]

I am afraid yes as it never had support for horizontal scroll

I asked It much time ago....

Antonio
ok, I wrote the missing methods and now full scrolling is supported, even with mouse dragging.
If you wish I can send to you the modified full source code by mail

thank you for support

[Antonio Linares]

Dear Roberto,

Great!!!

It is so encouraging when FWH users reach a real Masters level!

Yes please, send me the code and we will include it in FWH, big thank you!
