The version of mine is 7.4.2.569. Sometimes, when I create a new project, and add some files to the project, then compiler and link. The project can save and can open with the files. Then, I add other files to the project for update the program. then compiler and link. now, close the project , then ...

Thanks all. I do a little change /******************************************************************************/ void myGrid::Copy(wxCommandEvent &event) { wxString copy_data; bool something_in_this_line; copy_data.Clear(); for (int i=0; i<GetRows();i++) { something_in_this_line = false; for (i...

The attachment is the source code.
I compile the code use wxWidgts2.8.12, the background of the wxToolbar refreshed OK,
but it not refreshed when compile by wxWidegets2.9.3.

我也遇到了这个问题，究其原因是因为头文件和库文件不一致导致的。

I met this trouble too, because of the header files is not in accordance with the lib files.
You should use the right header files, or link the right libs.

I solved it by use the OpenCV2.4.2.

When I use cvFindContours with wxWidgets I copy the code in the OpenCV dir sampe/c/squares.c, than change the GUI to wxWidgtes, But the cvPyrUp and cvFindContours is crashed. And cvCanny( tgray, gray, 0, thresh, 3 ); Only 3 is well ,5 and 7 crashed. Please forgive my pool English. // returns sequenc...

我测试了，和用wxImage效果一样，我发现把那个文件对话框移到旁边，再打开图片，就能显示了，
我用英文也再跨平台板面问了一下，原来需要在EVT_PAINT中绘制，不然的话，重绘的时候就会把图片搞没掉，
所以之前文件对话框在显示的对话框之上，就不会显示出来图片了。
谢谢！
Windows平台和Linux平台不一样的地方，远远多过文档所说的。

Hi, You're painting in a wxClientDC, which works. Soon after, OnPaint() is called, which overwrites what you just displayed. You need to override the panel's OnPaint() and paint the image there, using a wxPaintDC. Regards, David Thanks very much for your reply. I use OnPaint() EVT_PAINT I test the ...

bitmap 用带参数wxBitmapType的版本试试。 就是直接用wxBitmap(const wxString& name, wxBitmapType type)来读取图片，然后再显示么？ if( dialog.ShowModal() == wxID_OK) { wxString FilePath_Name = dialog.GetPath(); //wxImage image(FilePath_Name); wxBitmap bitmap(FilePath_Name,wxBITMAP_TYPE_JPEG); wxClientDC dc(Panel1); dc.DrawBitm...

就会出现闪烁的问题。

昨天刚刚解决了，在外部把图片处理好，转化成wxBitmap，然后，在UpdateUI事件中，绘制图片
具体可以参考这个
http://wiki.wxwidgets.org/An_image_panel
关键是，只在UpdateUI事件中调用DrawBitmap方法，这样就不闪烁了。
我之前闪烁，是因为在UpdateUI事件中，同时处理了图片。

不明白为何不用wxStaticBitmap+wxSizer,俺曾用该方案做过测试，可以满足要求。

显示图片的区域是固定不变的，窗口没有标题栏，也不能拉伸。
使用wxStaticBitmap显示图片大小不一样时，这个控件的大小会变，就不符合我的要求了。
通讯录的照片大小都不一样，所以，我就没有使用wxStaticBitmap控件。如果显示同样大小的图片，用这个控件还算可以，但是也会发生拖动到屏幕边缘时，显示的图片会被擦掉，被其他窗口覆盖的话，移开其他窗口也会被擦掉。
