Using Qt modal popups on CCpilot VS

Printer-friendly versionPrinter-friendly versionPDF versionPDF version
The iMX6 display computers CCpilot VS and CCpilot VI2 uses a combination of Wayland, Weston and Qt that has a problem with modal popups, resulting in that a Qt application running in Weston cannot set a popup as modal.

It is possible to do a work-around to create a modal popup. A QtWidgets example is attached to this article to show three examples of modal popups on the VS.

Another approach can be to not use Weston and run a Qt application in EGLFS mode instead. A separate article describes how this can be done.
