But the thing is that wxExecute doesn't handle redirection Really? What about wxProcess::Redirect(), wxProcess::GetInputStream(), wxProcess::GetOutputStream() etc? You need to subclass wxProcess, create an instance of it and pass it to wxExecute. Check the "exec" sample, look for occurrences of "My...

I didn't have time for a deeper look, but the clearing of the background with DrawRectangle() seems to be the problem. If i just add dc.Clear() before or after DoPrepareDC(), the redraw issue goes away.

Can you create a minimal, compilable sample that shows the problem?

Try adding the wxFULL_REPAINT_ON_RESIZE window style flag. Despite its name, it sometimes fixed redraw issues in scrolled windows, even when they're happening while scrolling, not resizing.

I looked into the sources, and it seems there is no way to read these values.

Or do I have to bind to all childwindows? That depends on what you want to do. In most cases you probably want wxWindow::CaptureMouse() https://docs.wxwidgets.org/trunk/classwx_window.html#a5c72c6260a73ef77bb0b1f7ec85fcfef If that's not sufficient for your task, you have to bind to all descendants,...

In python, I am using this code to plot to auinotebook page:
how I could do this using C++?

Does the C++ wrapper have an equivalent to "FigureCanvas"? That that's probably the class you need.

This is really Matplotlib question. If you find a way to write the data as some kind of bitmap, you can dispay it in wxwidgets. According to this post , you can do it with "imsave", but it seems using a tempfile is the only way.

I couldn't find what kind of outputs matplotlib supports, from the sample code i can only see that it can generate a PDF. If it can also create any kind of image/bitmap, you could write a small wrapper class that just takes that image and draws it onto a panel. https://wiki.wxwidgets.org/Drawing_on_...

Is this from real code?

Try:

wxDataViewListCtrl::ItemToRow
https://docs.wxwidgets.org/trunk/classw ... ad30be241f

wxDataViewListCtrl::RowToItem
https://docs.wxwidgets.org/trunk/classw ... ff6b2f7fd5

From the "dataview" sample, code to delete all seletected items: void MyFrame::DeleteSelectedItems() { wxDataViewItemArray items; int len = m_ctrl[Page_Music]->GetSelections( items ); for( int i = 0; i < len; i ++ ) if (items[i].IsOk()) m_music_model->Delete( items[i] ); }

Under Windows ::SetThreadLocale() is called to set the locale, so creating another wxLocale instance in the thread should work. But for the other platforms, i don't see any equivalent code in <wxdir>/src/common/intl.cpp If it's only for number conversions, there are a few helper functions in wxStrin...

Look in the base class, there is wxDataViewCtrl::GetSelections
