How to make wxWidgets password visible, I am using 'wxTE_PASSWORD' flag?

I am using wxWIdgets to show a textbox and using 

m_passwordText = new wxTextCtrl(m_panel, wxID_ANY, wxT(""), wxDefaultPosition, wxSize(250, wxDefaultSize.GetHeight()), wxTE_PASSWORD);

I want to make this text visible sometimes and sometimes invisible(black dots). Is there any way that I can achieve this ?

According to the wxWidgets 3.0 manual, you can do it with wxGTK but not wxMSW (windows).

WIth GTK, to dynamically change a textbox style, you can do something like this:

textbox->SetWindowStyle(wxTE_PASSWORD);
textbox->Refresh();

On Windows, it looks like there is a backdoor way to change it, with this:

bool hidepwd = true;
HWND hwnd = (HWND) textbox->GetHandle();
SendMessage(hwnd, EM_SETPASSWORDCHAR, hidepwd ? 0x25cf: 0, 0); // 0x25cf is ● character
textbox->Refresh();

There's an old discussion of doing this on the wxWidgets forum here: https://forums.wxwidgets.org/viewtopic.php?t=15093
