我写的一个监控视频程序，想实现双击视频全屏，再双击回复原来大小，求助哪里错了

[timeyg]

我写了一个监控视频程序，显示网络摄像头的实时内容，想实现双击视频全屏，再双击回复原来大小，但是调试的时候是视频的整个窗口全屏，而不是视频全屏（窗口里面还有其他的按钮什么的）而且视频的大小没有变化，另外再双击的时候整个窗口就没有了但是程序没有退出调试，小弟是新手，请教各位前辈，我的程序应该怎么修改。

请各位高手帮忙看看，我想实现的功能是：
1，双击视频全屏，再双击回复原来大小（只有视频变为全屏）

[Delphi_A7]

汉邦DVR？ 看到7000SDK了。

汉邦DVR？ 看到7000SDK了。
[/Quote]是啊，用的汉邦的摄像头，从网站下载的SDK，请指教啊，控件全屏。。。。

没人回答，自己弄出来了，结贴都郁闷
