Get button face color at runtime

[Graham1]

I know the color of the button face is supposed to be clBtnFace but on my PC that gives $F0F0F0. When I look at the actual color of my buttons when I run my program it's $E1E1E1. I assume my theme is messing things up.

How can I find the actual color used by the button face at runtime?

To find the actual color used by the button face at runtime, you can use the GetSysColor function in your code to retrieve the system color for COLOR_BTNFACE. This will give you the color currently being used, considering any theme or visual style applied to your system. Here's a sample code snippet in C++:

Code: C  [Select][+][-]

1. COLORREF btnFaceColor = GetSysColor(COLOR_BTNFACE);
2.  

This will return the actual color being used, so you can compare it to the expected value.

Thank you! With that information I was able to find that it's included in LCLIntf, and there is an example as the "Show System Colors" button in:

C:\<Lazarus folder>\examples\canvas_test

And that handles both Windows and Linux, I think.

Thanks again.
