VC 按钮颜色设置.doc

这是一个实现自绘CButton的类,期望对大家有点帮助,我提供这个类,只是为大家提供一个自绘控件的思路,你可以在此基础上,随意地修改代码,直到它能完成你所需要的功能.其它控件的自绘,原理了和这个差不多.1.#if !defined(AFX_BUTTONST_H_1271FF9C_E28C_4D3B_B429_AFE65924A5D0_INCLUDED_) 2.#define AFX_BUTTONST_H_1271FF9C_E28C_4D3B_B429_AFE65924A5D0_INCLUDED_ 3.4.#if _MSC_VER 1000 5.#pragma once 6.#endif / _MSC_VER 1000 7./ ButtonST.h : header file 8./ 9.10./ 11./ CButtonST window 12.13.class CButtonST : public CButton14.15./ Construction 16.public:17.
