General / Re: WxWidgets/SFML program crashes with an X window system error (BadAccess)

« on: February 04, 2017, 06:25:41 am »

So, I compiled gtk2, libx11, and sfml with debug symbols, and here is what I get for a back trace when breaking on gdk_x_error.
Versions used are:
libx11-1.6.4
gtk2-2.24.31
sfml-2.4.1
wxgtk-3.0.2

General / Re: WxWidgets/SFML program crashes with an X window system error (BadAccess)

« on: February 04, 2017, 05:46:23 am »

I'm having similar trouble. I've tried pretty much every variation of code I can find online to get the handle for a GtkWidget.
Arch Linux - SFML 2.4.1, wxwidgets 3.0 (gtk2).

I'm compiling gtk2 with debug symbols at the moment in the hopes of getting a meaningful backtrace.

Code: [Select]

#include <wx/wx.h>
#include <SFML/Graphics.hpp>
#include <gtk/gtk.h>
#include <gdk/gdkx.h>


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

class MyFrame : public wxFrame
{
    public:
        MyFrame();
};

class MyControl : public wxControl, public sf::RenderWindow
{
    public:
        MyControl(wxWindow *parent,
                  wxWindowID id,
                  const wxPoint &pos=wxDefaultPosition,
                  const wxSize &size=wxDefaultSize,
                  long style=0,
                  const wxValidator &validator=wxDefaultValidator,
                  const wxString &name=wxControlNameStr
                  );
       
        virtual ~MyControl(){};
};

bool MyApp::OnInit()
{
    wxFrame *frame = new MyFrame;
    frame->Show(true);
    return true;
}

MyFrame::MyFrame() : wxFrame(NULL,
                             wxID_ANY,
                             "Test",
                             wxDefaultPosition,
                             wxSize(800, 600))
{
    new MyControl(this, wxID_ANY);
}

MyControl::MyControl(wxWindow *parent,
                     wxWindowID id,
                     const wxPoint &pos,
                     const wxSize &size,
                     long style,
                     const wxValidator &validator,
                     const wxString &name) :
                     
                     wxControl(parent,
                               id,
                               pos,
                               size,
                               style,
                               validator,
                               name)
{
    GtkWidget *widget = m_wxwindow;
    if (!GTK_WIDGET_REALIZED(widget))
    {
        gtk_widget_realize(widget);
    }
    GdkWindow *gdkWin = widget->window;
    sf::RenderWindow(GDK_WINDOW_XWINDOW(gdkWin));
}

wxIMPLEMENT_APP(MyApp);


Code: [Select]

[dmartins@sirschmoopy tmp]$ g++ -g `wx-config --cxxflags` `pkg-config --cflags sfml-graphics` `pkg-config --cflags gtk+-2.0` -o test main.cpp `wx-config --libs` `pkg-config --libs sfml-graphics` `pkg-config --libs gtk+-2.0`

[dmartins@sirschmoopy tmp]$ ./test
The program 'test' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAccess (attempt to access private resource denied)'.
  (Details: serial 45 error_code 10 request_code 2 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
