@Kent-Dorfman So do I, I want to know how to use opengl in QPainterPath.

@JonB I have checked it few times and even tried to connect via VS, with Visual Studio, it worked perfect and took 2 min to set it up. thank you for the functions, I will check it out

@JonB Simple answer to that will be "run as admin" - but, as stated above - this is something you should not do.

Heads-up for anyone reading this. I have come across this topic in trying to solve my new post at https://forum.qt.io/topic/112224/signal-slot-vs-direct-call-and-related-question, where I need to know which window/widget has the focus when a (main window) menu is invoked. The OP (@Elsworth55 )'s question here seems "alarmist"! Of course we need Qt to tell us which widget is focussed when a menu is invoked, else we're in trouble! Maybe it never got an answer because I do not find the behaviour reported by the OP here. Tested under Qt 5.12.2, Linux. I find that QApplication.focusWidget() does return the correct, currently-focussed widget. I have tested this on both a generic QWidget and a QLineEdit, and I have tested both when the menu is pulled down (QMenu::aboutToShow()) and when a item is clicked (QAction::triggered). In all cases I found it worked, so I don';t know about this OP's the QLineEdit that was previously in focus will get focus restored after clicking the menu item but when you click on a menu item it gives focus to the menu, so the focusWidget() will be the menu

Thanks @kshegunov I wil redo my plugin

@KroMignon This works fine, Thanks :)

@anil_arise thank you very much

@J-Hilk said in Warnings.: @Stevendragoes said in Warnings.: I have put the DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000 into the .pro file and it still gives me the error. I said remove it, not add is 😏 might have been se issue 🙈 LOL okok I will remove it. I thought Disable means like it will remove the warnings

@SGaist Alright, I'll give that a try. Thanks very much!

Hi, Did you use windeployqt to prepare your application for deployment ?

@Mozzie said in Did QByteArray have memory limit?: Is there any document about "QByteArray will not handle more than 2GB in Qt5"? Just take a look at the ctors, the access functions and the resize/size ones and it's clear that it can't contain more than 2GB ...

@hskoglund I made it finally, guess what i have done ? i changed the libstdc++-6.dll and libgcc_s_dw2-1.dll files to make the three files ( libstdc++-6.dll and libgcc_s_dw2-1.dll and libwinpthread-1.dll ) with the same date ( from 2014 ) and now it work perfectly, thanks for your Help i don't know why but when i deployed the date of libstdc++-6.dll and libgcc_s_dw2-1.dll have changed ( or maybe he taked the wrong one ) [image: dcef4a1d-16bc-4ff7-96ee-92b563060f2e.png]

@DonCoder You dont need your scene for this. Just check which view has focus. QGraphicsView * view view->hasFocus(); or QApplication::focusWidget();

@pengxu If you look at Qt Creator sourcecode, you can see that this is a custom widget with grid view and custom item delegates https://github.com/qt-creator/qt-creator/blob/f2351b06e05f5a129df1e6a38557c692687674c6/src/plugins/qtsupport/gettingstartedwelcomepage.cpp#L262 QGridView is deprecated, I guess, but you can use a QTableWidget or QListWidget.
