General and Desktop

@christian-ehrlicher Yes I know. I was trying to state in my comments that I obtained the byte array and was continuing. I agree that was not clear. I have solved the issue - my test jpg file had a non-compliant embedded profile. Many thanks for taking the time to help!

@devoo Are you trying to change textureSize of QQuickPaintedItem Class ?

@ofmrew please be sure to post book name in https://forum.qt.io/category/6/announcements :) (when its ready)

The best method to solve dependence problem is setting the environment variable. ``` C:\qt\qt-5.13.0-deploy\bin ``` But you should know it is a bad method for multiple qt.

@jonb Okay, I got it. Thanks bro!

According to this video, it should be possible to run the application both locally and remotely: https://vimeo.com/304349023

which style parameter do I have to edit to control the color of item when the widget loses focus? QTreeView::item:active { color: red; } /* When widget has focus*/ QTreeView::item:!active { color: blue; } /* When widget doesn't have focus*/ if I do show-decoration-selected: 1; How do I control decoration color ? It depends on the platform styling. For example on Windows it only colors on hover the little arrow that expands/collapses the branch and that arrow is painted by a system style call so you can't control its color. You can however replace the system styling and change the branch images to your own with any color you like. See Customizing QTreeView for examples.

I would rather be on the side of a path clash with Anaconda's installed version of Qt.

Hi, Since you have a commercial licence, I would recommend opening an issue directly from your account as you have access to support.

I used the Version you recommended, with the Version 1.38.27 the compilation will successfully. Here a Tutorial to setup: 1. Downloaded qt web installer (linux) from qt.io 2. Installed qt 5.13 (complete) => with sources and Webassembly 3. => Since 5.13 i think there is no need to compile Webassembly on his own like on 5.12 anymore. 4. Than i installed emcc like the instruction on emscription.org said. git clone https://github.com/emscripten-core/emsdk.git cd emsdk git pull ./emsdk install sdk-1.38.27-64bit ./emsdk activate sdk-1.38.27-64bit source ./emsdk_env.sh sudo apt-get install python2.7 sudo apt-get install cmake sudo apt-get install default-jre After i have done that i verified the emcc installation. Everything is fine. 5. Started QtCreator => There is already an QtWebassembly Kit but without an Compiler 6. Added emcc and em++ compiler to QtCreator (custom-compiler) Name: emcc Compiler-Path: ~/work/privat/project/emsdk/emscripten/1.38.27/emcc Path to Make: /usr/bin/make ABI: x86,linux,generic, elf,64bit QT-mkspecs: empty Name: em++ Compiler-Path: ~/work/privat/project/emsdk/emscripten/1.38.27/em++ Path to Make: /usr/bin/make ABI: x86,linux,generic, elf,64bit QT-mkspecs: empty Everything else on Default. 7. Added Compiler to QtWebassembly-Kit 8. DONE

Finally. This code works fine. void onPrint(QPrinter* printer) { QPagedPaintDevice* device = printer; QPainter painter; painter.begin(device); int w = device->width(); int h = device->height(); painter.drawLine(0,0,w,h); painter.drawLine(0,h,w,0); painter.drawEllipse(QPointF(w/2, h/2), w/10, w/10); painter.drawText(0, h, "pixels"); printer->newPage(); painter.end(); }

Hi yes it is. Just use the view as parent and it will be on top. QPushButton *button = new QPushButton("Im on top!",view); button->move( 100, 0); // use move to move it around

Everything seems to work OK without doing anything special as long as I am careful not to mix up which connection is used by which thread, so I am marking this as "solved".

Thank you. I wonder what additional dynamic link libraries I need，and I have used depends.exe to find these dll.

Thanks for your response. :)
