disabled button sends EVT_BUTTON events

[Felix Wohlfrom]

Hello,

I recently run in a really weird behavior of wxwidgets.

I got an wxDialog (but it also works with wxFrame, see example below) in which I had a button and a wxTextCtrl.
The button is disabled on frame creation, but set as default.
If I click the return key, nothing happens as expected.
But if I select the textCtrl and then press return, the button event will be fired.
If I compile the exact same code on windows, no events are generated as expected.
My Version of wxWidgets is 2.8.12.1-6ubuntu2 on ubuntu 11.04 amd64.

Test code, compiled with "g++ Test.cpp `wx-config --libs --cxxflags` -o test":

#include <wx/wx.h>

class TestWindow: public wxFrame
{
 public:
  TestWindow();

 private:
  void OnOkClick(wxCommandEvent& WXUNUSED(e));
  DECLARE_EVENT_TABLE()
};

BEGIN_EVENT_TABLE(TestWindow, wxWindow)
 EVT_BUTTON(wxID_OK, TestWindow::OnOkClick)
END_EVENT_TABLE()

TestWindow::TestWindow():
wxFrame(NULL, wxID_ANY, _T("Test"))
{
 wxSizer* sizer = new wxBoxSizer(wxVERTICAL);
 wxTextCtrl* textctrl = new wxTextCtrl(this, wxID_ANY);
 wxButton* button = new wxButton(this, wxID_OK, _("&Press me"));
 button->SetDefault();
 button->Enable(false);

 sizer->Add(textctrl);
 sizer->Add(button);
 this->SetSizer(sizer);

 this->Layout();
}

void TestWindow::OnOkClick(wxCommandEvent& WXUNUSED(e))
{
 std::cout << "This shouldn't happen" << std::endl;
}

class Test: public wxApp
{
 private:
  bool OnInit();
};

DECLARE_APP(Test)

IMPLEMENT_APP(Test)

bool Test::OnInit()
{
 TestWindow* win = new TestWindow();
 return win->Show();
}
