2007 style question

[Dietmar Jahnel]

Is there a way to check if someone uses "classical windows" desighn in XP or Vista ?
IsAppThemed() still returns .T.
In this case menu and messagebar are 2007 style, dialogs look "old" which gives a strange look in that combination.

Dietmar

IsAppThemed() just checks is the themes manifest file is included in the EXE

We need to find a way to detect if the user has the classic look

Hope you can find a way!

Dietmar,

Google is our friend

One possibility would be to check the value of ThemeActive in the registry under: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ThemeManager

I believe a value of 0 means that no themes are in use (Windows Classic Style) and a value of 1 means that themes are in use (Windows XP style).

Call OpenThemeData. This will return a handle to the theme, which, if NULL indicates that the visual style manager is disabled or there is no information for that control, which means that you should continue to draw using your default routines.

Is that an existing FW or Harbour function, or is it an API?

Antonio,
could you please post the code to do that.
We are about to release a new version of our software...

Thanks,
Dietmar

It's an API:

Code: Select all  Expand view

HTHEME OpenThemeData( HWND hwnd, LPCWSTR pszClassList );

Dietmar,

Here you have a working sample:

Code: Select all  Expand view

function Main()

   MsgInfo( IsThemeActive() )

return nil

#pragma BEGINDUMP

#include <windows.h>
#include <hbapi.h>

typedef BOOL ( * PFISTHEMEACTIVE ) ( void );

HB_FUNC( ISTHEMEACTIVE )
{
   HINSTANCE hDLL = LoadLibrary( "UxTheme.dll" );
   PFISTHEMEACTIVE IsThemeActive;
   
   if( hDLL == NULL )
   {
      hb_retl( FALSE );
      return;
   }
   else
      IsThemeActive = ( void * ) GetProcAddress( hDLL, "IsThemeActive" );
     
   if( IsThemeActive )
      hb_retl( IsThemeActive() );
   else
      hb_retl( FALSE );   
   
   FreeLibrary( hDLL );
}   
   
#pragma ENDDUMP

nice - that's it!

But I noticed that there seems to be a little painting problem with bars without themes. Right of the bitmaps there is a darker grey...

I send the image to your per mail

Dietmar,

If you don't use the 2007 clause then you have to use the 3D clause to get the colors and painting that you want

Many Thanks, now the look is consistent with and without themes!
