To change color of a tree object

Enrico,

Excellent :-) I also tried it but my code had a mistake so I thought that the implementation was going to be more complex.

Very good!

Enrico,

These new methods in Class TTreeView makes it automatic and FiveWin compatible:

Code: Select all Collapse

   METHOD Initiate( hDlg ) INLINE Super:Initiate( hDlg ), ::SetColor( ::nClrText, ::nClrPane )

   METHOD SetColor( nClrText, nClrPane ) INLINE ;
      Super:SetColor( nClrText, nClrPane ), TVSetColor( ::hWnd, nClrText, nClrPane )

This code in method New():

Code: Select all Collapse

   if ! Empty( oWnd:hWnd )
      ::Create( CTRL_NAME )
      oWnd:AddControl( Self )
      ::SetColor( nClrFore, nClrBack ) // New !

and finally just one C function call:

Code: Select all Collapse

CLIPPER TVSETCOLOR( PARAMS ) // hWnd, nClrFore, nClrBack
{
   TreeView_SetBkColor( ( HWND ) _parnl( 1 ), _parnl( 3 ) );
   TreeView_SetTextColor( ( HWND ) _parnl( 1 ), _parnl( 2 ) );   	
}

Now the sample code is just as:

Code: Select all Collapse

    @ 0, 0 TREEVIEW oTree COLOR CLR_WHITE, CLR_GREEN

No extra calls required

Hello Mr.Antonio

CLIPPER TVSETCOLOR( PARAMS ) // hWnd, nClrFore, nClrBack
{
TreeView_SetBkColor( ( HWND ) _parnl( 1 ), _parnl( 3 ) );
TreeView_SetTextColor( ( HWND ) _parnl( 1 ), _parnl( 2 ) );
}

should be included where?

Hello Mr. Antonio

Thank you for your suggestion.

I have inserted the following code at the bottom of treeview.c in
winapi directory and tried to compile it. It is giving the following
errors:

Warning W8019 treeview.c 234: Code has no effect in function TVSETCOLOR

Warning W8019 treeview.c 235: Code has no effect in function TVSETCOLOR

I don't have knowledge in C.

Please advise me what to do. Or else please provide me the correct
treeview.c link to compile without any warnings.
