设置菜单条及菜单项背景色
1、设置菜单条背景色
- // 菜单栏
- m_wndMenu.LoadMenu(IDR_MAINFRAME);
- SetMenu(&m_wndMenu);
- // 改变菜单条背景颜色
- MENUINFO menuinfo;
- menuinfo.cbSize = sizeof(MENUINFO);
- menuinfo.fMask = MIM_BACKGROUND;
- menuinfo.hbrBack = ::CreateSolidBrush(RGB(203, 228, 253));
- CMenu* pMenu = GetMenu();
- ::SetMenuInfo(pMenu->m_hMenu, &menuinfo);
- DrawMenuBar();
2、设置菜单项背景色
重载CMenu类，重写DrawItem()方法。
网上有一个CMenuEx类，只要设置m_colMenu属性就可以了。该类可以实现Windows开始菜单风格，即菜单项可带有图标。
