--------------------------------------------------- -------自定义的TShockwaveflash.ocx---------------- --------------------------------------------------- --------------------------------------------------- 添加功能:对鼠标在 flash.ocx 中的信息捕获.---------- --------------------------------------------------- 可捕获鼠标信息有: 1.鼠标在控件中移动时的坐标值; 2.鼠标右击时弹出菜单的设置; 3.鼠标点击控件时移动窗体; 4.鼠标是否移入控件; --------------------------------------------------- 编写原因: 我一直在作一个flash播放器:D-Flasher. 所以,要在其中捕获鼠标的一些消息. 但原 TShockwaveFlash 组件没有这些方法. 只能通过:Application.OnMessage:=Form.Msgproc; 这样的并不高级的办法.所以作了这么一个东西. 对 TShockwaveFlash 组件作了自定义. 在原来控件上加了对鼠标的行为的监控. 使得对 Flash 控件的鼠标消息处理的效率提高了. 用起来也方便了不少. 所以共享出来.若存在什么错误,还请指正. 由于本人水平有限,也是处于学习中. 也有许多不完善的地方,欢迎大家进行修改. --------------------------------------------------- 源文件:CustomFlash.pas.你可以对它进行编译. 源码: {---------------------------------------------------------------} {---------------自定义的TShockwaveflash.ocx---------------------} {检测:1.鼠标在控件中移动时的坐标值;2.鼠标右击时弹出菜单的设置; } { 3.鼠标点击控件时移动窗体;4.鼠标是否移入控件; } {---------------------------------------------------------------} {制作日期: 2004-8-23 [ending722] e-mail:ending722@163.com } {-----------------------------------------孤血雁工作室 杨光-----} unit CustomFlash; interface uses SysUtils,Classes,Controls,Menus,windows,forms, Messages,OleCtrls, ShockwaveFlashObjects_TLB; type TCustomFlash= class(TShockwaveFlash) private MPosX:integer; MPosY:integer; //鼠标在控件上的 X Y.
