Do you actually have to output to the console? Are you developing a console application?

You need something that converts the 8bit UTF8 byte stream into a stream of (decoded) wide characters. The wxTextCtrl will not do it by itself. Googling found this (very old) post (untested): https://stackoverflow.com/questions/148403/utf8-to-from-wide-char-conversion-in-stl https://en.cppreference....

Sorry, but in this case you can't blame the documentation, you just need to know how to read a C++ method declaration correctly. shortcutGrid->CreateGrid( 10, 2, wxGrid::wxGridSelectRows ); If you had looked into the "grid" sample that comes with wxWidgets, you could have found this: void GridFrame:...

Panel1->SetSizer(BoxSizer1); SetSizer(BoxSizer1); This can't be correct. A sizer can only be assigned to one window. Remove the second line. BoxSizer1->Add(Button1, 1, wxALL|wxALIGN_CENTER_HORIZONTAL|wxALIGN_CENTER_VERTICAL, 5); If you run a debug build, this should give an assert, because using wx...

Which wxWidgets version is your wxPython version based on?

The issue seems to be related to this: https://trac.wxwidgets.org/ticket/16088#comment:4
The workaround before the fix was to catch the wxShowEvent of the main frame and re-calculate the layout then

In other words, what makes a focus pass from one window to another? - the user clicks an a control that doesn't have focus - the user uses keyboard navigation to move focus to another control, e.g. pressing TAB in a text control - it can also happen programmatically, if the application sets focus t...

The window that has focus receives key events, that's it.

The most common use of focus events is to catch wxEVT_KILL_FOCUS on a wxTextCtrl to get notified when the control loses focus, e.g. to perform validation on the content of the control.

CallAfter( [this] { slider->GetParent()->Refresh() ; } ;) seems to have fixed the odd slider behavior. Now I'm wondering why. CallAfter ensures two things: 1) The code gets called after all currently pending events have been handled 2) The code is guaranteed to get called in the context of the main...

Calling SetValue() will also trigger the event handler for the slider. In case there is one, is there anything in it that could interfere? Also, try a delayed Refresh using CallAfter: CallAfter( [this] { slider->Refresh(); // alternative slider->GetParent()->Refresh(); }); If that doesn't work, i'm ...

wxWidgets itself has no control for it. You could try:

wxFreeChart: https://iwbnwif.github.io/freechart_doc ... index.html
wxMathPlot (pretty old): https://wxmathplot.sourceforge.io/screenshot.shtml

As Audacity is open source, you could check its sources, too.

Unfortunately all my buttons are not in a panel, and there is no way to copy and paste them into a panel. I will have to move them in one at a time grrrr.

The buttons don't have to be in a panel, just use the parent of the buttons (which is probably the mainframe in your case).

Regarding the actual drawing operation that should work, but it's possible that wxPdfDocument still embeds the image data with alpha. Try calling wxImage::ClearAlpha() https://docs.wxwidgets.org/trunk/classw ... d9065628b1

Not that i know if. Try the IRC channel: http://www.wxwidgets.org/support/irc/

You need to bind the event handler to the window returned by wxGrid::GetGridWindow

I don't know the Python equivalent for this.

I don't want to maitain an itermediate std::vector<data_item> because the exteranal store could potentially contain millions of objects I wouldn't use a vector, but a hash, but this is what you'll need. You need a container that maps the row-number of the listctrl to the m_id of the underlying row ...
