C++ (Cpp) onGeometryChanged Examples

Example #1

File: DisplayDevice.cpp Project: yutokt/android_vendor_intel

bool DisplayDevice::prepare(hwc_display_contents_1_t *display)
{

    log.v("DisplayDevice::prepare");

    if (!initCheck())
        return false;

    Mutex::Autolock _l(mLock);

    if (mConnection != DEVICE_CONNECTED)
        return true;

    if (!display)
        return true;

    // check if geometry is changed
    if (display->flags & HWC_GEOMETRY_CHANGED)
        onGeometryChanged(display);

    if (!mLayerList) {
        log.e("prepare: null HWC layer list");
        return false;
    }

    // update list with new list
    return mLayerList->update(display);
}

Example #2

File: panel.cpp Project: 91yuan/bones

LRESULT BSPanel::handlePositionChanges(UINT uMsg, WPARAM wParam, LPARAM lParam)
{
    switch (uMsg)
    {
    case WM_WINDOWPOSCHANGED:
        onGeometryChanged(*(WINDOWPOS *)lParam);
        break;
    }
    return 0;
}

Example #3

File: CDiagramProxyWidget.cpp Project: jetcodes/JetMind

CDiagramProxyWidget::CDiagramProxyWidget(CDiagram *d)
	: CDiagramNode(d),
	  m_widget(NULL),
	  m_proxy(NULL)
{
	m_proxy = new QGraphicsProxyWidget(this);
	m_proxy->setParentItem(this);
	m_proxy->setVisible(true);
	
	connect(this, SIGNAL(geometryChanged()), this, SLOT(onGeometryChanged()));
}
