      @Andrex_Qt said in Real time Plotting Line chart: It doesn't seem to have Pie-Chart, can you confirm? Yes, true. There is no pie-chart as such. @Andrex_Qt said in Real time Plotting Line chart: is this library free QCustomPlot was released under GPL license and is free to use in free software.

      @vishbynature It's config.log file located in the same directory from which you called configure. It is a text file, nothing special. Look for compile errors in that file related to to what you need.

      @vishbynature I don't claim to understand what the best way to do whatever you want here is. Maybe @Pablo-J-Rogina's suggestion of a database. The one thing I can tell you is that achieving whatever you are attempting by seeking to byte #80 in a text file and overwriting what is there is not the right approach. If you want some solution which involves sticking with text files, it should look something like: open the existing file for read, open a new file for write, read stuff from old and write to new, making whatever modifications you wish as you go along, close both, delete old file, rename new to old. A few more steps than you wanted! Or, if file not too large, read whole file into some memory structure, make your changes there, write whole memory structure back to the file, completely replacing it.

      You should always use the full path to the qmake binary of the Qt version you want to use to build your project/library/module.

      It's not a problem of Qt Creator. The mkspec used for the RPI3 is still valid unless your sysroot comes from a Debian Stretch were they have changed the library name. You need to modify the mkspec under devices that matches the Rpi3

      @Sivamani-V said in How to connect to mysql server in ubuntu 16.04?.: QMYSQL Driver not loaded. Available drivers: QMYSQL QSQLITE QMYSQL3 This gets asked so many times, here & elsewhere. Googling for your message will bring up many hits. Under Linux/Ubuntu it's usually libmysqlclient or libqt5sql5-mysql or similar which is missing/has dependencies missing/wrong version.

      Hi @Tegan, Not sure what the best approach is, but I'd: check the installer's md5sum against https://download.qt.io/archive/qt/5.6/5.6.3/md5sums.txt compare the output of ldd qt-opensource-linux-x64-5.6.3.run on both hosts, then run the installer with gdb Cheers.

      I am experiencing this problem on 5.11.2 running Linux Mint. So it is still there. Using the following formulation: QColorDialog dlg(colored->getColor()); dlg.setOption(QColorDialog::DontUseNativeDialog); dlg.setOption(QColorDialog::ShowAlphaChannel); dlg.open(this,SLOT(slot_colorChanged(QColor))); dlg.exec(); First problem: the dialog initializes with color black, not the given color. When pressing OK, the slot is triggered but the color is always color white, whatever is selected in the dialg. So essentially it does not work at all. using the formulation QColor newColor = QColorDialog::getColor(m_color, this, QString(), QColorDialog::DontUseNativeDialog); does work as was mentioned before

      @raven-worx I don't have any experience with TTS either, also I can't find much info about the current infrastructure on Linux, resp. on KDE. I have installed speech-dispatcher. And I can make it speak in the terminal, using its own spd-say command. I'm not sure how speech-dispatcher and flite are related. I think speech-dispacher is an abstraction layer / daemon, and flite is one of several "engines" it can use. spd-say --list-output-modules says: OUTPUT MODULES flite cicero generic dummy espeak The following packages that seem to be relevant have been installed: speech-dispatcher libspeechd2 flite libflite1 speech-dispatcher-flite libqt5texttospeech5 libqt5texttospeech5-dev qtspeech5-flite-plugin Note that no qtspeech5-speechdispatcher-plugin (or similar) exists in the repo. But looking at the Qt Speech sources, it seems there should be such a plugin. Anyways, when I build an application for testing .... QTextToSpeech::availableEngines() returns "flite" availableLocales() gives "en_US" and availableVoices() says "kal16".

      @ajcurtis said in QtCreator can not load plugins UBuntu 16.04: QApplication: invalid style override passed, ignoring it. But it is running now? If so then just ignore that warning.
