Functions

glContext()

QPlatformGLContext * QWaylandEglWindow::glContext ( ) const

virtual

Reimplement to return the glContext associated with the window.

Reimplemented from QPlatformWindow.

Definition at line 82 of file qwaylandeglwindow.cpp.

        QWaylandEglWindow *that = const_cast<QWaylandEglWindow *>(this);

        that->mGLContext->setEglSurface(surface);
    }

    return mGLContext;
}

newSurfaceCreated()

void QWaylandEglWindow::newSurfaceCreated ( )

protectedvirtual

Reimplemented from QWaylandWindow.

Definition at line 96 of file qwaylandeglwindow.cpp.

Referenced by QWaylandEglWindow().

{
    if (mWaylandEglWindow) {
        wl_egl_window_destroy(mWaylandEglWindow);
    }
    wl_visual *visual = QWaylandScreen::waylandScreenFromWidget(widget())->visual();
    QSize size = geometry().size();
    if (!size.isValid())
        size = QSize(0,0);

    mWaylandEglWindow = wl_egl_window_create(mSurface,size.width(),size.height(),visual);
    if (mGLContext) {
        EGLNativeWindowType window(reinterpret_cast<EGLNativeWindowType>(mWaylandEglWindow));
        EGLSurface surface = eglCreateWindowSurface(mEglIntegration->eglDisplay(),mGLContext->eglConfig(),window,NULL);
        mGLContext->setEglSurface(surface);
    }
}

setGeometry()

void QWaylandEglWindow::setGeometry ( const QRect &  rect )

virtual

This function is called by Qt whenever a window is moved or the window is resized.

The resize can happen programatically(from ie. user application) or by the window manager. This means that there is no need to call this function specifically from the window manager callback, instead call QWindowSystemInterface::handleGeometryChange(QWidget *w, const QRect &newRect);

Reimplemented from QPlatformWindow.

Definition at line 67 of file qwaylandeglwindow.cpp.

{
    QWaylandWindow::setGeometry(rect);
    if (mWaylandEglWindow) {
        wl_egl_window_resize(mWaylandEglWindow,rect.width(),rect.height(),0,0);
    }
}

setParent()

void QWaylandEglWindow::setParent ( const QPlatformWindow *  parent )

virtual

This function is called to enable native child widgets in QPA.

It is common not to support this feature in Window systems, but can be faked. When this function is called all geometry of this platform window will be relative to the parent.

Reimplemented from QPlatformWindow.

Definition at line 75 of file qwaylandeglwindow.cpp.

{
    const QWaylandWindow *wParent = static_cast<const QWaylandWindow *>(parent);

    mParentWindow = wParent;
}

windowType()

QWaylandWindow::WindowType QWaylandEglWindow::windowType ( ) const

virtual

Implements QWaylandWindow.

Definition at line 62 of file qwaylandeglwindow.cpp.

{
    return QWaylandWindow::Egl;
}
