 |
|
Hi
How to change colors on a TTrackBar?
I put a TTrackBar on a TPanel and I want the TrackBar to use the same
background color as the Panel.
But the TrackBar color dos not change, it is the same as the Panel color at
design / build time.
tryed to find any ->Color property on TTracBar but I faild.
It woud be nice to set color for the handel, background and window in the
TTrackBar, is it posible?

The Trackbar is supposed to take the same color as its parent
control (your panel). It just doesn't work correctly. In my
version of BCB (6 Ent) the color changes, when the trackbar
gets focus. So I can solve the problem here as follows:
Panel1->Color = clRed;
TrackBar1->SetFocus();
Maybe that works for you, too?
If want the tackbar to have another color, then set the brush
color. Try this:
Panel1->Color = clRed;
TrackBar1->Brush->Color = clBlue;
TrackBar1->SetFocus();

Yes. You would have to use Windows API functions. The trackbar
is actually a Windows control wrapped by the VCL TTrackBar. Use
the TrackBar's Handle to access the underlying Windows trackbar,
catch Windows messages and do the painting. If you google for
"windows trackbar colors" in Google Groups you will find some
code snippets to show what I am talking about. |

Thank you!
It is a bit of work to fix it!
I have to check if the trackbar are visible first to be abel to setfocus.
if(ControlPanel->Visible){
try {
FrekvensTB->SetFocus();
GainTB->SetFocus();
PreGainTB->SetFocus();
}
}
And I have alot of TTrackBars in my program....
