移动无边框的Winform持有鼠标右键，可能使用本地方法 [英] Move a borderless Winform holding right mouse button, possibly with native methods

问题描述

我有一个情况，我想握住它的客户区鼠标右键移动窗口的形式;形式是无国界的，因为我已经说。

我想移动它本身（如果可能的话，否则其他的答案都OK太）。我的意思是它的行为方式，当你按住标题栏鼠标左键（使用鼠标移动之类的东西，我得到了很多奇怪的行为，但也许这只是我）。

我看过周围很多东西和这个职位看起来有用

我尝试了各种方法来使用并通过的 http://msdn.microsoft.com/en-us/library/ff468877%28v=VS.85 ％29.aspx 找到其他有用的东西，并WM_NCRBUTTONDOWN就在我的脑海，但WndProc中没有检测到，也许是因为它是由表格处理？

任何建议表示赞赏，感谢

I have a situation where I would like to move a windows form by holding right mouse button on it's client area; the form it's borderless as i've stated.

I would like to move it "natively" (if possible, otherwise other answers are ok too). I mean the way it behaves when you hold left mouse button on the titlebar (with mouse-move and things like that I get a lot of strange behaviours, but maybe it's just me).

I've read around a lot of things and this post looks helpful

I tried various way to use that and watched through http://msdn.microsoft.com/en-us/library/ff468877%28v=VS.85%29.aspx to find other useful things and WM_NCRBUTTONDOWN came in my mind, however the wndproc doesn't detect it, maybe because it's handled by the form?

Any suggestion are appreciated, thanks

解决方案

public partial class DragForm : Form
{
    // Offset from upper left of form where mouse grabbed
    private Size? _mouseGrabOffset;

    public DragForm()
    {
        InitializeComponent();
    }

    protected override void OnMouseDown(MouseEventArgs e)
    {
        if( e.Button == System.Windows.Forms.MouseButtons.Right )
            _mouseGrabOffset = new Size(e.Location);

        base.OnMouseDown(e);
    }

    protected override void OnMouseUp(MouseEventArgs e)
    {
        _mouseGrabOffset = null;

        base.OnMouseUp(e);
    }

    protected override void OnMouseMove(MouseEventArgs e)
    {
        if (_mouseGrabOffset.HasValue)
        {
            this.Location = Cursor.Position - _mouseGrabOffset.Value;
        }

        base.OnMouseMove(e);
    }
}
