This plugin does not support propagateSizeHints()

[rambo-mmh]

I have already followed the tutorial(http://www.qt-project.org/wiki/Raspberr ... ners_Guide) to cross-compile qt5. And I wrote a simple "helloworld" qt5 application in the qtcreator on my ubuntu12.10 host. Then I deployed it through the qtcreator deployment tool. Everything looks like well! But when I ran it on my raspi, there was only a full screen panel without the menu and window border. In the terminal, I got a message: This plugin does not support propagateSizeHints().
Please give me some help! Thank you very much!

I have the same problem. Is there any solutions?

That is how Qt5 works on the Pi by following the most common guides. Your program will by default use the EGLFS backend and render to the whole screen. It will basically behave more like a phone-app than a desktop-application. But your app will have proper hw-acceleration.

Qt5 supports several rendering backends and they are selected with the "-platform" parameter.

You can try "helloworld -platform xcb" and that might render to your X-desktop. If the xcb plugin doesn't exist you will get a list of available platforms you can try.
