[wxPython/wxWidegts] AboutDialogInfo & Modal

[dodle]

Is there a way to make an AboutDialogInfo/AboutBox window modal? I haven't been able to find it anywhere in the wxPyDocs or wx docs. Currently, when the AboutBox is open, I can still interact with the main window and open as many about boxes as I want, which doesn't seem like it should be the default behavior.

Here is some sample Python code:

import wx

class MainWindow(wx.Frame):
    def __init__(self, parent, id, title):
        wx.Frame.__init__(self, parent, id, title)
        
        self.bg = wx.Panel(self, -1)
        
        about_button = wx.Button(self.bg, -1, "About")
        
        wx.EVT_BUTTON(about_button, -1, self.ShowAbout)
        
        self.about = wx.AboutDialogInfo()
        
    def ShowAbout(self, event):
        wx.AboutBox(self.about)

class MyApp(wx.App):
    def OnInit(self):
        frame = MainWindow(None, -1, "Test")
        frame.Show()
        self.SetTopWindow(frame)
        return True

app = MyApp(0)
app.MainLoop() 

and sample C++ code:

#include <wx/wx.h>
#include <wx/aboutdlg.h>

class MainWindow : public wxFrame
{
  public:
    MainWindow(const wxString& title);
    void ShowAbout(wxCommandEvent& event);
  private:
    wxAboutDialogInfo about;
};

MainWindow::MainWindow(const wxString& title) : wxFrame(NULL, -1, title)
{
    wxPanel *bg = new wxPanel(this);

    wxButton *about_button = new wxButton(bg, -1, _T("About"));

    about_button->Connect(wxEVT_COMMAND_BUTTON_CLICKED, wxCommandEventHandler(MainWindow::ShowAbout), 0, this);
}

void MainWindow::ShowAbout(wxCommandEvent& event)
{
    wxAboutBox(about);
}


class MyApp : public wxApp
{
  public:
    virtual bool OnInit();
};

IMPLEMENT_APP(MyApp)

bool MyApp::OnInit()
{
    MainWindow *frame = new MainWindow(_T("test"));
    frame->Show();
    SetTopWindow(frame);
    return true;
}
