I filled in the <No Compiler> fields and the issue was worked out. :)

Something like this : QList<int> savedSize; MySplitterHandle *splitterHandle=qobject_cast<MySplitterHandle*>(splitter.handle(1)); connect(splitterHandle,SIGNAL(Clicked()),this,SLOT(handleClickedSot())); void handleClickedSot() //slot { QTimer::singleShot(50,this, &Widget2::showHideWidget); } void Widget2::showHideWidget() { m_ShowHideFlag=!m_ShowHideFlag; if(m_ShowHideFlag) { savedSize=splitter.sizes(); QList<int> newSize(savedSize); newSize[0]=0; //hide first widget splitter.setSizes(newSize); } else { splitter.setSizes(savedSize); } }

Hi to all As of Qt 5.11 there is a static function in QSysInfo class: QByteArray QSysInfo::machineUniqueId() https://doc.qt.io/qt-5/qsysinfo.html#machineUniqueId

@lansing said in Calling a process in the main app and return the process's window ID?: The problem I have is that I don't know how to get the window id of child process after I opened them. You create them, you communicate with them through shared memory and you've access to it's QProcess and therefore to it's stdout pipe - I think these are enough communication channels to pass the winid.

Solved, overrode the standard event() and just used event.type() == QEvent::hovermove to get what I needed.

@Cobra91151 Well the continue is just optimization. if one is visible, no reason to check the others. Works the same checking all, though. Yeah, i guess so. even i didn't notice what but maybe both checking text and visibility in the same loop had some side effect.

Thank you for the reply. I used Ui::MainWindow, because it didn't recognize MainWindow. Turns out i had a circular dependency issue with the #include files.

I've submitted a bug report: https://bugreports.qt.io/browse/QBS-1433?jql=resolution %3D Unresolved AND reporter %3D currentUser()

Hello, I managed to do it using the last argument in QAbstractItemModel::dataChanged(const QModelIndex &topLeft, const QModelIndex &bottomRight, const QVector<int> &roles) to fulfill the task. Just wanted to update this in case someone else needs it as it requires less manual work. connect(tableWidget->model(), &QAbstractItemModel::dataChanged, [this](const QModelIndex& index, const QModelIndex&, const QVector<int>& roles){ if (std::find(roles.begin(), roles.end(), Qt::EditRole) == roles.end())//wasn't caused by entering cell return; //rest of code

@Christian-Ehrlicher Thanks for the tip and will do. Mike

Solved it by adding QThread::msleep(150); to the dbus method before showing the menu.

@Kent-Dorfman Many thanks,

Hi @Joshua-Qt, why do you actually want to mix MFC and Qt? You should be aware, that Qt (same as MFC) uses an event loop in background. If you want to combine both, both event loops must be run. That is surely not impossible, but advanced stuff that needs a deep understanding on what's going on in background. Regards

Tested on macOS but it's working fine... Can you test with the 5.13 preview ?

don't worry, i have found how i can do that.. yes it's understand me but he need to configure to talk the same language. And to do that, i need to send him many trame on serial port . but i have understand how he did it with class : CANMessage can_message; he created the class, it's not a basic class .. so i need to re created the same class to allow me send the good trame ..

Hi, to get the size of the SAFEARRAY, because it's 2D, you need to ask for the lower and upper bounds of both the dimensions, say something like this: long iLBoundX, iUBoundX,iLBoundY, iUBoundY; char * data; SafeArrayGetLBound((*var_array.pparray),1,&iLBoundX); SafeArrayGetUBound((*var_array.pparray),1,&iUBoundX); SafeArrayGetLBound((*var_array.pparray),2,&iLBoundY); SafeArrayGetUBound((*var_array.pparray),2,&iUBoundY); SafeArrayAccessData((*var_array.parray),(void**)(&data)); long szX=iUBoundX-iLBoundX+1; long szY=iUBoundY-iLBoundY+1; Note: this is a just a guess!

You're trying to copy the object into the list. QObjects are not copyable. To fix this you can change the list to be a list of pointers instead.

Yes i have see that befor your answer ^^ its COM3 and not portname When i setPortName ty !
