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

I can't pinpoint exactly what's wrong, but subclassing wxGenericProgressDialog doesn't sound like a good idea. A progress dialog has a very narrow usage pattern and it can't even be used like a "normal" wxDialog, let alone a wxFrame. { wxGenericProgressDialog dlg(..); dlg.Show(); while (something) {...

I don't know anything about wxLua or wxWidgets under OSX, but i would first focus on the actual error message: Do you link to AVKit when building wxLua? If not, try adding it. If yes, try to find out why it's not found.

Supposed you have a paint event handler, do it like this: void SomeClass::OnPaint(wxPaintEvent &event) { static wxLongLong s_lastTime = -1; wxLongLong actTime = ::wxGetLocalTimeMillis(); double fps = 0.0f; if( s_lastTime != -1 ) { fps = 1000.0f / (actTime - s_lastTime).ToDouble(); } s_lastTime = act...

Is is possible to add theming options to a application, like giving user option to change color of controls, something like CSS or maybe a simple config file No. You can only modify the color from individual controls, but even that is limited depending on the underlying native control and platform ...

The "child frame" you're creating should be a modal dialog. Here's some sample code for a dialog for entering one string: class DataEntryDialog : public wxDialog { public: DataEntryDialog(wxWindow *parent, const wxString &title) : wxDialog(parent, wxID_ANY, title) { wxBoxSizer *mainSizer = new wxBox...
