Functions

lower()

void QFbWindow::lower ( )

virtual

Reimplement to be able to let Qt lower windows to the bottom of the desktop.

Reimplemented from QPlatformWindow.

Definition at line 342 of file fb_base.cpp.

{
    QList<QFbScreen *>::const_iterator i = mScreens.constBegin();
    QList<QFbScreen *>::const_iterator end = mScreens.constEnd();
    while (i != end) {
        (*i)->lower(this);
        ++i;
    }
}

raise()

void QFbWindow::raise ( )

virtual

Reimplement to be able to let Qt rais windows to the top of the desktop.

Reimplemented from QPlatformWindow.

Definition at line 321 of file fb_base.cpp.

{
    QList<QFbScreen *>::const_iterator i = mScreens.constBegin();
    QList<QFbScreen *>::const_iterator end = mScreens.constEnd();
    while (i != end) {
        (*i)->raise(this);
        ++i;
    }
}

repaint()

void QFbWindow::repaint ( const QRegion &  region )

virtual

Definition at line 422 of file fb_base.cpp.

Referenced by QFbWindowSurface::flush().

{
    QRect currentGeometry = geometry();

    QRect dirtyClient = region.boundingRect();
    QRect dirtyRegion(currentGeometry.left() + dirtyClient.left(),
                      currentGeometry.top() + dirtyClient.top(),
                      dirtyClient.width(),
                      dirtyClient.height());

    QList<QFbScreen *>::const_iterator end = mScreens.constEnd();
    QRect oldGeometryLocal = oldGeometry;
    oldGeometry = currentGeometry;
    while (i != end) {
        // If this is a move, redraw the previous location
        if (oldGeometryLocal != currentGeometry) {
            (*i)->setDirty(oldGeometryLocal);
        }
        (*i)->setDirty(dirtyRegion);
        ++i;
    }
}

setGeometry()

void QFbWindow::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 453 of file fb_base.cpp.

{
// store previous geometry for screen update
    oldGeometry = geometry();


    QList<QFbScreen *>::const_iterator i = mScreens.constBegin();
    QList<QFbScreen *>::const_iterator end = mScreens.constEnd();
    while (i != end) {
        (*i)->invalidateRectCache();
        ++i;
    }
//###    QWindowSystemInterface::handleGeometryChange(window(), rect);

    QPlatformWindow::setGeometry(rect);
}

setVisible()

void QFbWindow::setVisible ( bool  visible )

virtual

Reimplemented in subclasses to show the surface if visible is true, and hide it if visible is false.

Reimplemented from QPlatformWindow.

Definition at line 485 of file fb_base.cpp.

{
    visibleFlag = visible;
    QList<QFbScreen *>::const_iterator i = mScreens.constBegin();
    QList<QFbScreen *>::const_iterator end = mScreens.constEnd();
    while (i != end) {
        (*i)->invalidateRectCache();
        (*i)->setDirty(geometry());
        ++i;
    }
}

setWindowFlags()

Qt::WindowFlags QFbWindow::setWindowFlags ( Qt::WindowFlags  flags )

virtual

Requests setting the window flags of this surface to type.

Returns the actual flags set.

Reimplemented from QPlatformWindow.

Definition at line 497 of file fb_base.cpp.

{
    flags = type;
    QList<QFbScreen *>::const_iterator i = mScreens.constBegin();
    QList<QFbScreen *>::const_iterator end = mScreens.constEnd();
    while (i != end) {
        (*i)->invalidateRectCache();
        ++i;
    }
    return flags;
}

visible()

virtual bool QFbWindow::visible ( )

inlinevirtual

Definition at line 129 of file fb_base.h.

{ return visibleFlag; }

windowFlags()

Qt::WindowFlags QFbWindow::windowFlags ( ) const

virtual

Returns the effective window flags for this surface.

Reimplemented from QPlatformWindow.

Definition at line 509 of file fb_base.cpp.

{
    return flags;
}

winId()

WId QFbWindow::winId ( ) const

inlinevirtual

Reimplement in subclasses to return a handle to the native window.

Reimplemented from QPlatformWindow.
