Ha, that is good to hear. Happy coding!

In openglwindow . cpp if(e->key() == Qt::Key_5){ filenam = QFileDialog::getOpenFileName(0,"Vali graafiku fail"); } Call from main also cause problems. Is only way to make opengl draw from other thread or could use same thread for gui as well?

@JKSH @JKSH said: One thing I noticed is that QPixmap objects read/write global objects without mutexes or any other thread locking. That's one good argument right there. Currently, the application never tries to work on the QPixmaps from different threads at the same time.

Hi, @arealperson said: Is QML like a normal scripting language ? What I’m asking is… Is it general purpose ? In the beginning, QML was designed as a quick and easy language to create GUIs. It consists of JavaScript plus custom declarative code which is similar to CSS/JSON. Since QML is a superset of JavaScript, you can use its engine for JavaScript scripting. QML is general-purpose. It is even used to implement a build system. Like, can I do anything in it just like I would use any other scripting language ? Things, like Flow control, User defined types, File IO, etc… What type of scripting work is QML not really made for ? Well... anything that's not suitable for JavaScript, I guess. I can’t find a good getting started tutorial about how to compile/execute a QML script. http://doc.qt.io/qt-5/topics-scripting.html http://doc.qt.io/qt-5/qtjavascript.html

Hi, You can't set the background of a QCompleter, it's not a QWidget. However you can style the widget that will use the QCompleter. Hope it helps

@jerome_isAviable said: getOpenFileUrls is not a member function per se, it's a static function, that's why you didn't got what you wanted.

I had the same problem trying to run my QTestLib QGuiApplication unit tests on a headless build system. I worked around it by providing a X virtual server. Xvfb :1 & DISPLAY=:1 make check pkill Xvfb

Nice ! Thanks for sharing :)

Were you using QSharedMemory to communicate between two objects of the same application ?

qt.conf is the recommended way for the plugins handling part

@devbrs You certainly must check if taglib is null. And you must use toUTF8() instead of toAscii(). The last problem is that some of the string conversion functions in TagLib don't appear to work with the QString conversion functions. Namely the functions that create c++ string and wstring objects: QString::fromStdString(tag->title().to8Bit()); QString::fromStdWString(tag->title().toWString()); The functions that return c style string pointers do work: QString::fromWCharArray(tag->title().toCWString()); QString(tag->title().toCString(true)); Now, why the string functions work on Linux and not on the Mac, I don't know. Perhaps you could delve into it.

In which way is your int send? If it is sent binary, you will have to extract it from your buffer. There is no automatic conversion. With QByteArray you may use toInt() However, you need to know the information type to be received.

@joeydonovan4 Then just add a property like for example autoSelectAllOnFocus to the new subclassed MyLineEdit and then in the overloaded method you either call home() or selectAll() in dependence of the property.

Sorry for long response , Running windows 7 Pro and mingw compiler. In terminal all works perfect , problem mostly is with floating window or variables tab on right under debug. Sometimes floating window turn gray and hard to see content, Probably will install linux version of qt also if it very stable.

Hi Chris, thank you very much I was able to solve it :). I tried something similar before but I think I have done sth. wrong with all these pointer stuff.. Cheers

Hi, thx, I added a report to Qt Jira. QTBUG-45114

@mcosta @sahadum Thank you for your responses! Both of these are great points. I have a similar implementation to Sahadum's suggestion in place regarding item roles, and Mcosta, that's the EXACT thing I was doing to determine if it's a child node. The only problem is, when I query my selectionModel->selectedRows(), my rows still are out of order. When I run my foreach loop, this is what's given to me: rows - 0, 0, 0, 1, 1, 1, 2, 3, 4, 5 deconstructed as below: item3:child1.row() ==0, item4:child1.row() == 0, item1.row()==0, item3:child2.row()==1 item4:child2.row()==1 item2.row()==1 This is the order that the rows are presented to me in the foreach loop. I tried ignoring child nodes, and then adding their data to my QStringList when I encounter a parent. This orders things properly, but what if I select ONLY a child line, for instance Item3:Child1 - this will be ignored and not be copyable. I must then copy the parent and get ALL the children. I still need a means of walking through my selectionModel that will give me the rows in the order they appear in my Treeview.

Thanks for your opinions, guys! So it's really safe to ignore this.

Hello, You have to write your own implemenation of QDataStream operators (<<,>>) for your String Class e.g. MyString QDataStream &operator<<(QDataStream &out, const MyString &string) {......} QDataStream &operator>>(QDataStream &in, MyString &string) {......}
