-·-</font></span></p><p><fontcolor="#ffffff">----</font>WINDOWS中窗口的常规移动方法,是用鼠标拖动标题栏来完成,但目前的WINDOWS程序中,存在很多的无标题栏窗口,这在多媒体流行的时代更是如此,形形色色的媒体播放机大都如此,还有输入法或者即时翻译等程序,其界面只有窄窄的一行,这样的程序在程序设计阶段必须进行特殊的处理,才能使之具有鼠标拖动功能,本人在DELPHI及VB程序设计中,找到了一种无标题栏窗口鼠标拖动的简单方法,可广泛应用在类似的程序设计之中。<p><fontcolor="#ffffff">----</font>基本原理:当无标题栏窗口进行鼠标拖动时,在一个最明显的事实,就是其鼠标在窗口中的坐标始终不变,所以如果能够在鼠标移动过程中,通过改变窗口在桌面上的坐标,而始终保持鼠标的相对坐标不变,即可实现鼠标的拖动效果;在具体的程序设计中,先在Mousedown()事件中记录鼠标位置,而在Mousemove()事件中根据鼠标的移动距离,实时修改窗体Form的Top及Left值,即可准确无误的实现窗口的鼠标拖动操作。利用此方法实现鼠标拖动,与常规的标题栏鼠标拖动在效果上有一点区别,因为标题栏拖动时,鼠标移动过程中不重画窗口,只有松开鼠标后在固定位置重画窗口,所以其速度较快,而采用此方法拖动过程中,每移动一步都需要重画窗口,对速度稍有影响,在慢一些的机器上会出现轻微的拖尾现象,但绝不会影响正常操作,而在586以上机器上或者高速显示系统下会完全克服这种现象。在实际程序设计时,窗口中可能有多种控件,若想使鼠标拖动窗口中的任何位置都可实现窗口移动,必须对窗口中的所有控件进行上述的鼠标位置记录与移动处理,即在MouseDown()与MouseMove()事件中加入下面的程序代码,当然与可以在窗口内设置一个专门用于窗口拖动的区域,这样只对此一个控件操作即可。<p><fontcolor="#ffffff">----</font>演示程序的编制:下面是一个利用DELPHI编制的时间显示程序,编制方法:在窗体内放置一个按钮Button1及一个时间控件Time1,使按钮呈横向矩形,其WIDTH足以显示下日期和时间,之后在相应的事件中输入以下程序中的代码,程序运行之后,其界面将只有按钮大小的窄窄一条,显示当前的日期和时间,用鼠标拖动窗口的任一部位,都可使窗口随之准确地移动,在窗体内按下鼠标右键退出程序。<p><fontcolor="#ffffff">----</font>以上方法及程序在WINDOWS95系统下、DELPHI2.0环境调试通过,经在VB5.0环境下试验,其效果与此一致。<p><fontcolor="#ffffff">----</font>附.PAS全部程序代码:<pre>unitformyd;interfaceusesWindows,Messages,SysUtils,Classes,Graphics,Controls,Forms,Dialogs,StdCtrls,ExtCtrls;typeTForm1=class(TForm)Timer1:TTimer;Button1:TButton;procedureFormCreate(Sender:TObject);procedureTimer1Timer(Sender:TObject);procedureButton1MouseDown(Sender:TObject;Button:TMouseButton;Shift:TShiftState;X,Y:Integer);procedureButton1MouseMove(Sender:TObject;Shift:TShiftState;X,Y:Integer);procedureButton1Click(Sender:TObject);private{Privatedeclarations}public{Publicdeclarations}end;//定义全程变量varForm1:TForm1;dx,dy:integer;implementation{$R*.DFM}//程序初始化procedureTForm1.FormCreate(Sender:TObject);beginform1.borderstyle:=bsnone;form1.height:=button1.height;⌨️
