Re: wxDC上DrawBitmap,怎么保持刷新而不闪烁

我测试了一下,也不可以,擦除背景函数如果为空,界面会显示一些界面窗口后面的窗口里的内容,而且照片在窗口拖到屏幕边缘时,也还是会被擦掉。

Re: =自我介绍=(新人可来这里对自己作自我介绍)

注册好久了,但是不经常来。
学习wxWidgets纯粹业余爱好。
工作是做纯硬件的,分立元件的电路开发,那些电感,电容,电阻,二极管,三极管之类,完全不需要编程…… :oops:
希望能在这里获得帮助,
对你也许很简单,对我可能会很难,谢谢!

wxDC上DrawBitmap,怎么保持刷新而不闪烁

类似通讯录,就是一个姓名,对应一个照片。 因为照片有大有小,所以我用wxPanel来显示图片: /* *显示用户照片 */ void TestFrm::DrawImageToWindow(wxImage* image,wxWindow* window) { wxClientDC dc(window); dc.SetBackground(*wxWHITE_BRUSH); dc.Clear(); wxCoord wdwidth,wdheight; dc.GetSize(&wdwidth,&wdheight); int oldwidth = image->GetWidth(); int oldhei...

when I search for OpenCV on Ubuntu,I find this: "I presume you compiled the library source on your linux platform. The problem is that when you configured using ./configure, the development lib for gtk2.0 wasn't detected(if it actually existed in your system). so when you ran the make command, it co...

You an use the wxThread or wxTimer in the program, use the OpenCV in the thread or with the wxTimerEvent. Oh , my English is very poor . You can download the Example I made. I play a AVI or WebCam in a wxPanel with two wxButtons. The link: http://forums.wxwidgets.org/viewtopic.php?t=27708 I hope you...

这个是一个wxWidgets和OpenCV的例子,一个wxPanel

这个是一个在wxWidgets和OpenCV联合的例子,相当简单,一个显示面板Panel,;两个按钮Play和Stop。不过有一点小问题,就是如果从视频文件获取画面的话,关闭程序的时候会报错。如果使用摄像头获取画面的话,就没问题了。
我试验了,使用其他程序,在关闭AVI视频(samples中的tree.avi)的时候也是报错,可能是我哪里处理的不好。如果有人能解决以下,就好了。
附件是两种显示的方法,一种使用wxTimer,一种使用wxThread.
