How to position apps inside weston compositor

lgyui

Dear sir,

I am working with TI AM57x EVM and use QT to develop my application.

My application run on wayland after weston-lauch.

But I cannot position my app on any display either HDMI or LCD.

In traditional QT program I can use QWidget::GetWindowHandle::SetScreen(QApplication::QDesktop::Screens[first]) to assign QWidget for multi-screens system.

And I can use QWidget::Geometry to assign position on screen.

But when run on wayland, the qwidget appear random and unable to control.

Does anyone point me how to ?

Hi Sir,

When I tested example/qwindow-compositor inside QtWayland under processors-sdk-v02.00.01, I got error message
-----------------------------------------------------------------------------------------------------------------------------------------------------------
Maybe another compositor is running.
Fatal : failed to open server socket.
-----------------------------------------------------------------------------------------------------------------------------------------------------------
So when I use the new demo program under processors-sdk-v02.00.01 : qt-opencv-opencl-opengl-multithreaded-1.3.3
and put setGeometry into demo code, the windows still popu randomly.

QRect geom = QRect(screenGeometry.width() / 4, screenGeometry.height() / 4, screenGeometry.width() / 2, screenGeometry.height() / 2);
mainwin.setGeometry(geom);

Can you stop weston and check with QtWayland compositor?
