To change color of a tree object

[MarcoBoschi]

If I try to color a Tree the background of items remain always white.
I have to obtain a tree of the same color of all others objects in a dialog.
Any trick?

Marco,

Please review samples\TreeDlg.prg

[MarcoBoschi]

Yes but background color of items remains White!

Marco,

Please check that you have these lines in Class TTreeView:

Code: Select all

METHOD ReDefine( nId, oWnd, nClrFore, nClrBack, lDesign, cMsg ) CLASS TTreeView

   DEFAULT oWnd     := GetWndDefault(),;
           nClrFore := oWnd:nClrText,;
           nClrBack := oWnd:nClrPane,; // GetSysColor( COLOR_WINDOW ),;
           lDesign  := .f.
...

Antonio,
The answer is Yes.
=============== from ttreevie.prg ==============
METHOD ReDefine( nId, oWnd, nClrFore, nClrBack, lDesign, cMsg ) CLASS TTreeView

DEFAULT oWnd := GetWndDefault(),;
nClrFore := oWnd:nClrText,;
nClrBack := oWnd:nClrPane,; // GetSysColor( COLOR_WINDOW ),;
lDesign := .f.

Antonio, do you need a sample of this problem?

Enrico,

samples\TreeDlg.prg is working fine.

I appreciate if you could provide another sample, thanks

Here it is:

Code: Select all

#include "Fivewin.ch"


FUNCTION MAIN()

    LOCAL oDlg, oTree

    DEFINE DIALOG oDlg;
           SIZE 400, 400

    @ 0, 0 TREEVIEW oTree COLOR CLR_GREEN, CLR_RED

    ACTIVATE DIALOG oDlg;
             ON INIT FILLTREE( oTree );
             CENTER

    RETURN NIL


STATIC FUNCTION FILLTREE( oTree )

    LOCAL oItem

    oItem = oTree:Add( "Test" )

    oItem:Add( "Test1" )
    oItem:Add( "Test2" )
    oItem:Add( "Test3" )

    oTree:Expand()

    RETURN NIL

As you can see, the colors of the subitems are still black on white.

Thank to Yout Enrico and Antonio.

Enrico, Marco,

If you try to build a similar sample using Word VBA built in Macro Editor, it does not show the BackColor property. It looks as it is not supported by Windows API. We are doing more research.

Thank you very much
Muchas gracias

Solved!

Code: Select all

#include "Fivewin.ch"


FUNCTION MAIN()

    LOCAL oDlg, oTree

    DEFINE DIALOG oDlg;
           SIZE 400, 400

    @ 0, 0 TREEVIEW oTree COLOR CLR_GREEN, CLR_RED

    ACTIVATE DIALOG oDlg;
             ON INIT FILLTREE( oTree );
             CENTER

    RETURN NIL


STATIC FUNCTION FILLTREE( oTree )

    LOCAL oItem

    oItem = oTree:Add( "Test" )

    oItem:Add( "Test1" )
    oItem:Add( "Test2" )
    oItem:Add( "Test3" )

    oTree:Expand()

    TVSETTEXTCOLOR( oTree:hWnd, CLR_GREEN )
    TVSETBKCOLOR( oTree:hWnd, CLR_RED )

    RETURN NIL


#pragma BEGINDUMP

#include "windows.h"
#include "commctrl.h"
#include "hbapi.h"

HB_FUNC( TVSETTEXTCOLOR )
{
    hb_retnl( ( LONG ) TreeView_SetTextColor( ( HWND ) hb_parnl( 1 ), hb_parnl( 2 ) ) );
}


HB_FUNC( TVSETBKCOLOR )
{
    hb_retnl( ( LONG ) TreeView_SetBkColor( ( HWND ) hb_parnl( 1 ), hb_parnl( 2 ) ) );
}

#pragma ENDDUMP
