Hello Alvise,
You have to set the Color property of the TButton
Try something like

Button1->Color=clRed; // this is not really a nice button color, but this
shall convain you that it works !

Where Button1 is the identifier of a TButton instance,
Note that you also can use the RGB macro to assign your own color values,
this gives
Button1->Color=(TColor) RGB(33,66,99);

If such coding tires you, you can do this at design-time by selecting the
button on you form, then picking up the wanted color in the object
inspector, at the row named Color.

Hi Alvise.
Sorry, but you can't.  TButton does not support color changes.  Check out
Torry's web site and see if you can find a button that does:

Re:The color of a button


Thanks for your response. I did like you said:

Quote
> You have to set the Color property of the TButton
> Try something like

> Button1->Color=clRed; // this is not really a nice button color, but this
> shall convain you that it works !

but at compile time I get the following error:

"Controls::Tcontrol::Color" is not accessible

then, trying this:

Quote
> Note that you also can use the RGB macro to assign your own color values,
> this gives
> Button1->Color=(TColor) RGB(33,66,99);

I get the above message again. Furthermore:

I CAN'T find Color in object inspector, this is why I posted the message
!

What is wrong with me ??? I use C++ Builder 3 professional.

Thanks for your help. A.V.

TButton doesn't support custom coloring

This won't work, because the colour of a normal TButton can't be changed.
Windows paints these buttons, and always in the default colour for that.
That is why TButton doesn't publish a Color property.

You can't change the color of the TButton but you can make a
panel that looks like a button by changing the BevelWidth property
to 2. You can also lower and raise the inner and outer bevels
as the user clicks on the button.

Use a another component. For buttons of every shape and size imaginable,
check out the ZieglerCollection, a shareware library of components:

Thanks Thomas ! Yours is a very good advice. Making a button using a
TPanel is better than using TButton. I can also change the shape of the
cursor to "HandPoint". I changed the BevelWidth property to 2, and add a
couple of statements in the OnClick handler:

a) first statement of the handler:

Panel1 -> BevelOuter -> bvLowered;

b) last statement of the handler:

Panel1 -> BevelOuter -> bvRaised;

Furthermore the "button" remains lowered during all the time that the
function is active.

Thanks again and regards. A.V.
