如何在mfc中使用图片控件移动窗口 [英] How do I move window using picture control in mfc

问题描述

在MFC应用程序中

我创建了一个没有边框的对话框，我在一个位图图像的对话框上放了一个Picture控件



所以我想用那个图片框作为标题栏



这意味着鼠标按钮在图片上向下移动或拖动鼠标时窗口也被移动< br $> b $ b

我该怎么办？



我的尝试：

In MFC application
I Created a Dialog with no Border and I put one Picture control on the dialog with one bitmap image

so I wanted to use that picture box as title bar

it means when mouse button is down on the picture and mouse is moved or dragged The window is also be moved

What should I do?

What I have tried:

LRESULT CMoveWinUsingPicDlg::WindowProc(UINT message, WPARAM wParam, LPARAM lParam)
{
	if( message == (WM_RBUTTONDOWN) )
	{
		//I think Here I can do something or suggest any other best place or solution
	}
}

{
	static bool mouse_down = false;
	static CRect MainRect;
	static CPoint point;
	
	switch(pMsg->message)
	{
	case WM_LBUTTONDOWN:
		GetWindowRect(&MainRect);
		point = pMsg->pt;
		ScreenToClient(&point);
		mouse_down = true;
		break;
	case WM_LBUTTONUP:
		mouse_down = false;
		break;
	case WM_MOUSEMOVE:
		CRect r;
		m_myPic.GetWindowRect(&r);
		if(mouse_down && r.PtInRect(pMsg->pt))
		{
			MoveWindow(pMsg->pt.x - point.x,pMsg->pt.y - point.y,
				MainRect.Width(),MainRect.Height());
		}
	}
	return CDialog::PreTranslateMessage(pMsg);
}
