We have a feature : drawing something based on egl on a qt window(we use QDialog). Egl need a EGLSurface and a EGLDisplay to get the feature work. EGLSurface eglCreateWindowSurface( EGLDisplay display, EGLConfig config, NativeWindowType native_window, EGLint const * attrib_list); In x11 based OS like ubuntu 12.04 , we use EGL_DEFAULT_DISPLAY to get display, the qt window’s winId() to cast to NativeWindowType It works well on X11 based OS. But when it comes to wayland ,it will crash at eglCreateWindowSurface, I googled a lot ,but rarely got something useful. Someone said that to get eglCreateWindowSurface work on wayland ,the native_window has to be a wl_egl_window type. I tried to get it like bellow: QDialog *dialog = new QDialog(mainW); dialog->setGeometry(QRect(0, 0, 720, 430)); dialog->show(); QPlatformNativeInterface *native = QGuiApplication::platformNativeInterface(); struct wl_display *wl_dpy = (struct wl_display *) native->nativeResourceForWindow("display", NULL); struct wl_surface *surface = static_cast<struct wl_surface *>( native->nativeResourceForWindow("surface", dialog->windowHandle())); struct wl_egl_window * wl_wind = wl_egl_window_create(surface, 720,430 ); use the wl_wind and wl_dpy to eglCreateWindowSurface , the app didn’t crash ,but the graphics we want to draw on the window can’t be seen. Is there someone met this before? Can somebody give some advices? Hi, I think the best would be to ask on Qt interest[1] mailing list. I'm sure that they help you with correct solution or workaround. In fact it is not Tizen specific.
