Description
- QQuickWindow::show() (with ivi-shell)
- QQuickWindow::hide()
- QWaylandWindow::setVisible(false)
- QWaylandWindow::reset(true)
- mShellSurface is deleted.
- QQuickWindow::hideEvent()
~~~ - main thread is blocked in QSGThreadedRenderLoop::releaseResources(.
- QSGThreadedRenderLoop::invalidateOpenGL on Render thread
- QWaylandGLContext::makeCurrent on Render thread
- QWaylandWindow::createDecoration on Render thread
- mShellSurface is null at this point, so Decoration plugin(libbradient.so) is loaded.
However, Decoration is not required in ivi-shell. Therefore, QWaylandWindow should store decoration policy of own's shell surface and it should be used in QWaylandWindow::createDecoration()
bool QWaylandWindow::createDecoration()
{
if (!mDisplay->supportsWindowDecoration())
return false;
static bool decorationPluginFailed = false;
bool decoration = false;
switch (window()->type()) {
case Qt::Window:
case Qt::Widget:
case Qt::Dialog:
case Qt::Tool:
case Qt::Drawer:
decoration = true;
break;
default:
break;
}
if (mFlags & Qt::FramelessWindowHint)
decoration = false;
if (mFlags & Qt::BypassWindowManagerHint)
decoration = false;
if (mSubSurfaceWindow)
decoration = false;
// when QQuickWindow's hide() is called, mShellSurface is null
if (mShellSurface && !mShellSurface->wantsDecorations())
decoration = false;
