Refresh/Repaint (Quicktime) and graphical Components...

HI there,

i've some major problems with my multimedial applications and the
c++builder.

Firstofall I'm searching a component (collection?) that is a progressbar
whos background and foreground can be customized bitmaps - so I an design it
like a blue tube which becomes a orange tube, when the position steps...

Also a bitmap-trackbar is searched with full transparency bar (not like the
LMD-Trackbar), because I want to design the thumb like an Ending of a Line
and the Line (A TShape?) should indicate the Position. And there are two
trackbars directly under each other, so I can simulate a
"Begin-End-Positioner". To draw the Indicator-shape, the Trackbar has to be
transparent...
The Trackbar of LMDTools isn�t that transparent andif I use a black width=1
panel instead of a shape, because panels are always in front of
tlmdcontrols, The Repainting won�t work (The thumb bitmap is there several
times, it won�t be erased correctly...)
The Trackbar of the "CoolComponents" also not work, because, the
Thumb-Bitmap was cut, when it arrives at max or min position and there
aren't any propertys to define a greater border...

And the greatest Problem: In combination with Quicktime the Refreshing and
MEssaging is miserable. If another window covers the Form and the quicktime
movie, only parts of the form are repaintet, the movie not. I don't know
exactly if the movie got a message to refresh?
Is there anybody who has build a quicktime app with refreshing and without
trouble?
I trie to make updatemovies, moviestask, Handle WM_WindowPositioned, make
COver and UncoverProcs... nothing works properly.
Is there any window-Message that comes to the form, if another windows
covers the form`and I can handle it to manually repaint?

I would be very thankful, someone could help me,
best regards,
Bjoern M. Albrecht
