C#創(chuàng)建磁性窗體的實(shí)現(xiàn)方法
更新時(shí)間：2024年04月17日 09:48:14 作者：wenchm
經(jīng)常會(huì)遇到一種情況,即當(dāng)拖動(dòng)一個(gè)窗體（主窗體）時(shí),其他窗體（子窗體）隨著該窗體移動(dòng),當(dāng)拖動(dòng)子窗體時(shí),其他窗體將不跟隨移動(dòng),這就是磁性窗體,所以本文給大家介紹了C#創(chuàng)建磁性窗體的實(shí)現(xiàn)方法,需要的朋友可以參考下
一、磁性窗體
經(jīng)常會(huì)遇到一種情況，即當(dāng)拖動(dòng)一個(gè)窗體（主窗體）時(shí)，其他窗體（子窗體）隨著該窗體移動(dòng)，當(dāng)拖動(dòng)子窗體時(shí)，其他窗體將不跟隨移動(dòng)，這就是磁性窗體。
二、磁性窗體的實(shí)現(xiàn)方法
在主窗體移動(dòng)時(shí)，通過改變跟隨窗體的Left和Top屬性值實(shí)現(xiàn)“磁性”。
(1)無標(biāo)題窗體的移動(dòng)
無標(biāo)題窗體的移動(dòng)主要是通過控件來移動(dòng)窗體，比如，用Panel控件來進(jìn)行。首先，在Panel控件的MouseDown事件中將鼠標(biāo)按下時(shí)的位置值(負(fù)值)存入到全局變量CPoint中，代碼如下：
private void panel_Title_MouseDown(object sender,MouseEventArgs e) CPoint=new Point(-e.X,-e.Y); //獲取鼠標(biāo)按下時(shí)的位置
然后，在Panel控件的MouseMove事件中按照CPoint變量的值，以屏幕坐標(biāo)平移指定的量，并用平移后的結(jié)果設(shè)置窗體的DesktopLocation屬性，代碼如下：
private void panel_Title_MouseMove(object sender,MouseEventArgs e)
if(e.Button==MouseButtons.Left)
{
Point myPosittion=Control.MousePosition; //獲取當(dāng)前鼠標(biāo)的屏幕坐標(biāo)
myPosittion.Offset(CPoint.X,CPoint.Y); //以屏幕坐標(biāo)平移指定的量
DesktopLocation=myPosittion; //設(shè)置當(dāng)前窗體在屏幕上的位置
}(2)Left屬性
該屬性用于獲取或設(shè)置控件左邊緣與其容器的工作區(qū)左邊緣之間的距離(以像素為單位)。語法格式如下：
public int Left {get;set;}
參數(shù)說明
屬性值：窗體左邊緣與其容器的工作區(qū)左邊緣之間的距離(以像素為單位)。(3)Top屬性
該屬性用于獲取或設(shè)置控件上邊緣與其容器的工作區(qū)上邊緣之間的距離（以像素為單位）。語法格式如下：
public int Top{get;set;}
參數(shù)說明屬性值：窗體上邊緣與其容器的工作區(qū)上邊緣之間的距離(以像素為單位)。二、設(shè)計(jì)一個(gè)磁性窗體的實(shí)例
本實(shí)例將制作一個(gè)磁性窗體，當(dāng)拖動(dòng)主窗體移動(dòng)時(shí)，兩個(gè)子窗體如果相連，則跟隨移動(dòng)。
- 三個(gè)窗體：主窗體Frm_Play.cs，2個(gè)子窗體：Frm_ListBox.cs、Frm_Libretto.cs；
- 鼠標(biāo)按下任一窗體頂部的控件，可以拖動(dòng)窗體；
- 拖動(dòng)子窗體時(shí)，會(huì)使得粘在一起的窗體分開，拖動(dòng)主窗體時(shí)會(huì)使粘在一起的子窗體隨動(dòng)；
- 拖動(dòng)主窗體靠近子窗體小于相互吸引的縫隙10時(shí)，松開鼠標(biāo)，靠近的窗體會(huì)像磁鐵一樣吸引在一起；主窗體吸引子窗體后，該子窗體還可以吸引其它子窗體；
- 雙擊主窗體的控件，激活所有窗體；
