Hi The qemf seems able to only rendering of EMF not generating it. What is the data you want to put in the emf file ? Qt has http://doc.qt.io/qt-5/qpicture.html#details that works like WMF but its not same (file) format at all. However, its pretty simle to generate WMF/EMF from windows API. (CreateEnhMetaFile)

I agree you need to use a state machine for that case. http://doc.qt.io/qt-5/qstatemachine.html probably helps putting down the skeleton already

@eDeviser said in Customizing QMainWindow by style sheet: Yes, this helps! I see the QMainWindow holds a QWidget which is set as cetralWidget. So It would be necessary to set the QMainWindow as centralWidget or to apply my css for the QWidget. Thank you for this hint. You have to apply your css in your qwidget ! Your css should be : centralWidget { background: yellow; width: 10px; /* when vertical / height: 10px; / when horizontal */ } centralWidget:hover { background: red; }

@deleted184 said in Qt5.9 VNC Support: Hi guys! According to the changelog of Qt5.8, vnc is back. I'm currently on Qt5.9 and i was able to launch my application with vnc enable like this: ./myQt59app -platform vnc:size=272x480 Via my VNC client everything works very well, however i have nothing displayed on the screen of my board :( . Do you have any idea on how to launch a qt5.9 application on a board and have a remote access via VNC ? I am using qt5.9 and i am able to start my qt application with vnc backend.However, when seeing from vncviewer or bnvc on android, i can only see a small part of my applicaiton( 1024x600 for my applicaiton , but on vnc client i can only see 1/4 part of the whole display). The following is my procedure: on my embedded linux server, run ./myQt59app -platform vnc:size=1024x600 in terminnal; on andriod ,using vnc viewer or bVNC to listen to ip address and port of my linux device. But both app can only see nearly 1/4 of the whole display. What is your procedure?Thanks!

@Konstantin-Tokarev @SGaist I found the cause of those error, it is due to fonts.css in html files. When I removed the link from <head>, the application was successfully run without crashed. Just wonder, how come its not working now in qt5.8 but just nice back then in qt5.5 ? BTW, thanks both for your help and idea :)

I actually switched to QtAV for video output, and so far it's been working flawlessly under standard QT App setup. If I could ever get the QML/Quick setup to acknowledge it's been installed I'd test that end of things, but for now it's accomplishing exactly what I need. Thanks again for the assistance!.

I got it to work by changing 2 things export CPPFLAGS="-Os" And by removing the prefix in the configure, and installing it twice ( one in the sysroot of the toolchain ) and the other in the filesystem for the target sh $ICU_SOURCE_DIR/source/configure --host=arm-cortex_a8-linux-gnueabi -with-cross-build=$ICU_HOST_DIR --prefix="" if ! make -j5 DESTDIR=$SYSROOT install; then echo -e "${RED}Error making ICU Target ( sysroot )!${NC}" exit 1 fi if ! make -j5 DESTDIR=$PREFIX install; then echo -e "${RED}Error Installing ICU Target ( filesystem )!${NC}" exit 1 fi

Hi, I may be wrong but AFAIK, Apple changed recently its policy about dynamic library in application bundle. Thus its likely related to that. You should bring this question to the interest mailing list, you'll find there Qt's developers/maintainers. This forum is more user oriented.

Sorry to resurrect an old topic, but how did you manage to configure Qt on os x? I'm using Jared Wolff's toolchain but get stuck at ./configure and can't build a RPi-friendly qmake.

Go to Tools->Options...->Help->Documentation and see which docs are loaded. Also, check Tools->Options...->Build & Run->Qt Versions, maybe it is picking up your system Qt, however it is unlikely.
