如何实现浮动、状态自动提示
西安 梁 明
如果注意到Delphi4提供给TStatusBar类的新特性---AutoHint，那么要获
得这样的效果简直就是太
简单了！这样做，我们不需要写一句代码，而且，我们可以设置显示浮动
提示的截获时间、停留时
间、背景颜色等等。
下面，我来解释一下如何快速实现这个功能：
首先，我们必须明白，Delphi下的Hint实际上由两部分组成，中间由“|”
隔开，第一部分就是我
们需要的浮动提示，第二部分就是状态栏提示。当然，要说明的是，如果
我们只提供第一部分，那
么，系统将不区别这来两者，以同样的提示显示出来。
何为浮动提示，大家很容易理解，而状态栏提示即是在窗体的状态栏上显
示的提示。对于浮动提
示，我们很容易获得，只需将其组件的ShowHint属性设为True即可。在De
lphi4以前，要实现状态
栏提示，必须自己手动添加一个过程来实现，但是，在Delphi4中只需设置
TStatusBar的一个属性
即可，但是这也要付出代价，那就是“只能”在状态栏的第一个Panel中显
示。
具体做法是：
1、为需要提示的组件添加Hint属性（由两部分组成），并设置其ShowHin
t=True；
2、为窗体添加TStatusBar，并添加一个Panel，设置其AutoHint=True；
注意：如果你不想显示浮动提示，只需将Hint设置为“|what you want..
.”即可，意思就是将第
一部分设置为空！下面，我将举一例，程序本身并无价值，但是能体现出
这个意思。
关于如何改变浮动提示的截获时间、停留时间、背景颜色等等，可以查阅
一下全局变量
TApplication的帮助，本文暂时不涉及到，今后将专文论述！
