If you use the overload that takes a "void*", the object must be allocated on the heap and you're responsible for deleting it. If you use the overload that takes a "wxClientData*", the object must also be allocated on the heap but the listbox takes ownership and deletes it. If you only want to store...

Thanks for the contribution

FWIW, as it's essentially a (dual state) wxCheckBox, i would have used the same event for it.

I would suspect that the space in the path causes trouble.

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
