c++ win32 change trackbar background color

Question

I have a win32 API, developed in c++ and i can't find any useful information regarding how can i change the background color of a Trackbar component in windows Vista and above?

I am looking for a equivalent to .NET attribute called BackColor.

Answer 1

Winforms implements it by handling WM_CTLCOLORSTATIC for a TrackBar control. The example code in the linked SDK article should do the trick.

Answer 2

之前没有做过，但是请尝试使用NM_CUSTOMDRAW作为轨迹栏 ，然后在绘制控件时（可能在CDRF_NOTIFYPOSTERASE阶段）为该控件设置背景画笔和DC的文本颜色。
