Bitmaps and Button bars

[TimStone]

I know there have been changes regarding bitmaps and buttonbars. I did a search but could not find topics on the changes. Here are my questions:

1) Is there a thread or two that discusses the newer capability of higher resolution, or alpha bitmap, button bars ?

2) What would be a good file in the samples folder of these capabilities

Thanks ... I'm using 9.05.

Hello Tim,

The example shows any Window-Background and a Buttonbar on Top.
Just define the Image ( Alpha-Blended BMP ) for the Buttonbar => FILE c_path + "\system\format.bmp"

I started with the Bar-Tools ( comes close to the Button-Tools ) there it is possible, to test
the Bar-Size and included BMP's, how they look together on a defined Window-Background.
Some nice Button-Sets will be included as well.

Tim,

Alpha channel bitmaps are automatically detected and used from FWH.
All you have to do is to create an alpha channel bitmap and use it as you use other bitmaps.

You can find some alpha channel bitmaps in c:\FWH\bitmaps\AlphaBmp\*.bmp

Working on the Tools, I noticed after changing the Gradient, Style 2007 gets lost ?

Normal Buttonbar with Style 2007 and no Gradient change :

DEFINE BUTTONBAR oBar1 OF oWnd1 SIZE D_BUTTONH, D_BUTTONV 3DLOOK 2007 TOP
oBar1:SetColor( D_TCOLOR )



The same Buttonbar with Style 2007 and defined Gradient :

DEFINE BUTTONBAR oBar1 OF oWnd1 SIZE D_BUTTONH, D_BUTTONV 3DLOOK 2007 TOP
oBar1:SetColor( D_TCOLOR )
oBar1:bClrGrad = { || { { D_MOVE, D_COLOR1, D_COLOR2 },;
{ D_MOVE, D_COLOR2, D_COLOR1 } } }



Style 2007 gets lost with the new Gradient-Define ?

Thanks for the replies. I'm also reviewing the "whats new" notes ...

Tim,

Testing all possible Solutions I still found a wrong Position of the Buttonbar with :

DEFINE BUTTONBAR oBar1 OF oWnd1 SIZE D_BUTTONH, D_BUTTONV 3DLOOK 2007 BOTTOM

The Bottom of the Buttonbar is covered with the Messagebar.
Bottom Buttonbar must be Top Messagebar.



Best Regards
Uwe
