@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.

@Mihan When using Qt there is no reason to prefer system() over QProcess. Even @Kent-Dorfman's "stall the parent while the work is being done" can now be achieved with the one-liner convenience static function https://doc.qt.io/qt-5/qprocess.html#execute introduced a couple of releases ago if that's what you want. And unless you are doing something special with popen(), Qt's QProcess offers pipe redirection on stdin/stdout/stderr in a convenient package.

@J-Hilk thank you <3

@Fulgurance what @mrjj wrote! also foreach is deprecated you are supposed to use the std range based for. For example: for( QWebEngineView *task : *WebViewTasks ){ ... }

@Pl45m4 said in Creating Path /data/print: I dont know if QDir or QFile can access hidden dirs or files Yes, they can.

provide a minimum workable example

@SGaist It makes no difference how I do it: Win+Space, Alt+Shift (on Win 7) or by mouse via Input Indicator.

I solved this. The key was setData and Data functions. I created a list of objects from my query in my mainWindow function and sent it to my model. In Data, I returned the values for each column for the list of objects. Then in the SetData function, I set the values for that list in my switch statement. This way, my model was showing the editable list values instead of the query. When I selected submit, it updated the database with the saved queries from the values that were edited.

@SGaist said in shit start dateTime in order to have endDateTime and startDateTime on Work time: By the way, you might want to correct your thread title, it's missing an f in the first word and makes it a little bit out of context ;-) Fixed that - it burned my eyes ;)

@Ayush-Gupta said in Remove string from QStringList with higher number: I am looking for algorithm. Can you please help ? @Pl45m4 already told you how to do it.

@viniltc You can use Qt3D (C++ or QML) for that. You can use just a standard cube (other basic shapes are supported) or you could create your own mesh / .obj - file with e.g. Blender and import it. Qt3D https://doc.qt.io/qt-5/qt3d-index.html Here are some examples https://doc.qt.io/qt-5/qt3d-examples.html. I can recommend the ShadowMap QML Example (QML) and the Basic Shape C++ Example You can set the transformation by using QQuaternion and your quaternion data directly https://doc.qt.io/qt-5/qquaternion.html

there are open source MP3 decoder libraries. google search: "mp3 decoder library sourcecode"...
