How to make a wxFrame behave like a modal wxDialog object

Question

Is is possible to make a wxFrame object behave like a modal dialog box in that the window creating the wxFrame object stops execution until the wxFrame object exits?

Answer 1

Not sure this is a great answer but it worked.

bool WinApp1::OnInit()
{
  if (!wxApp::OnInit())
    return false;

  SettingsDialog dialog(m_settingsData);
  dialog.ShowModal();

  return false;
}

SettingsDialog::SettingsDialog(SettingsData& settingsData)
  : m_settingsData(settingsData)
{
  SetExtraStyle(wxDIALOG_EX_CONTEXTHELP);

  wxWindow* parent = nullptr;
  Create(parent, wxID_ANY, "Preferences", wxDefaultPosition, wxDefaultSize,
    wxDEFAULT_DIALOG_STYLE | wxRESIZE_BORDER);

The WinApp1 window is never given a wxFrame and never paints.
