VC中TabCtrl控件如何像对话框一样具有Resizing属性.

Question

RT.对话的Border有Resizing属性,但是TabCtrl没有,怎么才能让它有呢?

Answer 1

你要自己派生一个类来实现响应OnNcHitTest处理即可

Answer 2

LRESULT CTreeFile::OnNcHitTest(CPoint point)
{
// TODO: 在此添加消息处理程序代码和/或调用默认值
CRect rect;
GetWindowRect(&rect);
if(point.x <= rect.left+3)
return HTLEFT;
else if(point.x >= rect.right-3)
return HTRIGHT;
else if(point.y <= rect.top+3)
return HTTOP;
else if(point.y >= rect.bottom-3)
return HTBOTTOM;
else if(point.x <= rect.left+10 && point.y <= rect.top+10)
return HTTOPLEFT;
else if(point.x >= rect.right-10 && point.y <= rect.top+10)
return HTTOPRIGHT;
else if(point.x <= rect.left+10 && point.y >= rect.bottom-10)
return HTBOTTOMLEFT;
else if(point.x >= rect.right-10 && point.y >= rect.bottom-10)
return HTBOTTOMRIGHT; return CTreeCtrl::OnNcHitTest(point);
}
