问题描述
反正是有控制,您可以在移动窗体?
Is there anyway to control where you can move a form?
所以,如果我移动窗体,它只能在垂直轴移动,当我尝试以水平移动,没有任何反应。
So if i move a form, it can only be moved on the vertical axis and when i try to move it horizontally, nothing happens.
我不想要一个越野车实施类似locationchanged或移动事件,坡平回来内联。我不存在使用有点像的WndProc覆盖的方式,但寻找了一段时间后,我不能找到任何东西。请帮助
I dont want a buggy implementation like locationchanged or move event and poping it back inline. I no there is a way using something like a WndProc override but after searching for a while, i couldnt find anything. Please help
推荐答案
您最有可能要重写的WndProc和处理WM_MOVING消息。 :
You would most likely want to override WndProc and handle the WM_MOVING message. According to MSDN:
的WM_MOVING消息被发送到该用户正在移动一个
窗口。通过
处理此消息,
应用程序可以监视拖动矩形的位置
,如果需要,
改变其立场。
这将是一个办法做到这一点,但是,你显然需要tweek它满足您的需要:
This would be a way to do it, however, you would obviously need to tweek it for your needs:
using System.Diagnostics;
using System.Runtime.InteropServices;
using System.Windows.Forms;
namespace VerticalMovingForm
{
public partial class Form1 : Form
{
private const int WM_MOVING = 0x0216;
private readonly int positionX;
private readonly int positionR;
public Form1()
{
Left = 400;
Width = 500;
positionX = Left;
positionR = Left + Width;
}
protected override void WndProc(ref Message m)
{
if (m.Msg == WM_MOVING)
{
var r = (RECT)Marshal.PtrToStructure(m.LParam, typeof(RECT));
r.Left = positionX;
r.Right = positionR;
Marshal.StructureToPtr(r, m.LParam, false);
}
base.WndProc(ref m);
}
[StructLayout(LayoutKind.Sequential)]
private struct RECT
{
public int Left;
public int Top;
public int Right;
public int Bottom;
}
}
}
