用Java设计浮动按钮程序

　　广东韶关市十里亭电厂
梁颖健
---- 当今计算机的界面越来越漂亮。随着IE 和Office 97 的推出，又出现一个新颖的控件：浮动按纽。现在vc 中已经可以实现这种设计，而Java 中目前还没有类似的按纽。笔者最近分析浮动按纽的特点，完成了这个设计。

---- 浮动按纽特点分析:

---- 不难发现，浮动按纽其实就是一种欺骗视觉的设计。当按纽处于有效状态时，鼠标进入按纽区域，按纽的左侧和上侧产生一条白色线，右侧和下侧产生一条灰色线（窗体的背景为明灰色），就产生了按纽浮起的感觉；当按下鼠标时，按纽对侧的颜色交换，同时按纽中的图象和文字也向右下移动一个象素点，则产生按纽凹入的感觉；移出鼠标，灰白两色消失，图象和文字回移一个象素点，恢复原状。根据这些特点，浮动按纽存在五种状态：平面、浮起、按下、失效、消失。

---- 据此，设计一个完整的浮动按纽主要围绕这五种状态来进行，由另一个类提供提示信息；如果按纽没有提供失效状态下的图象, 则使用平面状态下的图像，过滤出一个失效图像，因此又需要一个类完成图像过滤。

---- 设计浮动按纽要点说明:

---- 浮动按纽类和工具提示类均由java.awt.Canvas 类派生, 失效图像类由java.awt.image.RGBImageFilter 派生。

---- 浮动按纽最多需要四个图像，最少需要一个图像。图像可以是一个image 或它的byte 数组形式。

---- 若是byte 数组形式，由java.awt.toolkit 类下的createImage 方法转换为image 形式。浮动按纽消失调用component 类的setVisible 方法完成，其余四种状态由paint 方法完成。设置文本使用setText 方法，设置工具提示类实例使用setTooltips 方法( 不设置这两项亦可)。产生提示调用工具提示类实例的setVisible 方法。为感应鼠标事件，对应mouseListener 接口中的方法, 浮动按纽中亦有五个方法，并返回一个布尔值确定是否已执行。

---- 提示信息由工具提示类中的setVisible-run-repaint-update-paint 过程完成。调用类实例时, 若线程处于停止或暂停状态，将先启动或恢复再执行。提示信息达到提示留屏时间后，被清除( 在此期间, 若浮动按纽产生第二个事件，提示亦会消失)。之后达到线程空运行时间，线程将被暂停，直到再有浮动按纽使用工具提示。提示留屏时间和线程空运行时间的参数通过setKeep 和setDelay 方法修改，单位为秒。在一个窗体中，一个工具提示类实例由所有浮动按纽类实例共用。

---- 为保证程序正确输出，还应注意以下几点:

---- 1. 为保证工具提示类实例可以覆盖在窗体的所有控件上，工具提示类实例应第一个使用add 方法添加到窗体中。

---- 2. 浮动按纽必须调用setVisible 方法才能显示或消失。

---- 3. 在添加浮动按纽前，应调用repaint 方法刷新屏幕，否则可能NullPointerException 异常。

---- 4. 此按纽是针对frame 设计，若用到Applet 中，请修改浮动按纽中的setEntered 方法中的鼠标位置计算。

---- 以下是程序代码:
