在MFC中使用HITTEST方法 [英] use of HITTEST METHOD in MFC

问题描述

先生/妈妈，我对MFC很陌生，谁能解释如何使用HitTest方法以及该方法的用途.我们可以用它来选择特定的客户区吗?例如我在客户区画了文字.已经从LButtonDown和LButtonUP以及MouseMove中获取了两个点，并以此点绘制了矩形.现在我想更改矩形的bkcolor ....请注意，我没有使用editview，请任何人帮助我........


在此先感谢

解决方案

1.要更改背景色，请使用FillRect方法，

void FillRect(LPCRECT lpRect,CBrush* pBrush);

从LButtonDown，LButtonUP点生成矩形.下面的链接为您提供有关FillRect的更多信息.

2. HitTest的行为取决于您所引用的窗口.它不是CWnd成员.

解决方案

1. To change back ground color use FillRect method,

void FillRect(LPCRECT lpRect,CBrush* pBrush);

Generate the rectange from LButtonDown, LButtonUP points.The following link gives you more information about FillRect.

2. The behaviour of HitTest will depends on the window you are refferening.It is not a CWnd Member.
