I tried to apply custom colors to ScrollBox background and scrollers. But scrollers are always of system color. I've set UseCustomScrollBars property in Form.OnCreate(), then colors were changed. But thumb color is the same as track color. It's very bad, especially when colors are not so bright.
I've added ThumbColor property to TScrollStyles. Modified modules are sent by email. But all my efforts had dead end. It's because your SBHook unit was developed for 32 bit platform only. Nothing can be customized in x64 platform. Looks like I'm giving up with my wishes to customize UI.
You should be more clear, when you declare that your component set supports x64 platform.
Do you have any plans to update SBHook for x64?
