Re: What is the correct way to response to the wxEVT_DPI_CHANGED event?

Hi, Vadim Zeitlin and Maarten Bent. I think I found a mistake.

In my test code, it has such line:

sizer->Add(new wxButton(page, wxID_ANY, _T("Hello World"), 
wxDefaultPosition, wxWindow::FromDIP(wxSize(250,50), 0)));

Which is totally wrong here, because I have used the wrong argument for the 
FromDIP( wxSize(250,50), 0 ), the second argument 0 is totally wrong.

Now, I have removed the second argument, and the result is: when I click 
the ResetMode button, I don't have the reduced button size. (Which shows in 
the third screen shot of the forum post here:
How does the FromDIP function work under different DPI scaling? - wxWidgets 
Discussion Forum — https://forums.wxwidgets.org/viewtopic.php?f=1&t=50267)

I'm sorry about that, I think it was a copy and paste error. Also, when we 
pass the second 0 argument, can the function report something, because it 
will call a function below:

static wxSize wxWindow::FromDIP ( const wxSize &   sz,
const wxWindow *   w 
) 

Where the w pointer is 0.
