General and Desktop

@Oleksandr-Malyushytskyy Yes possibly. Could be Qt WebEngine.

@qtProgrammer said in Qt debug info with Online installer on Windows: I also need Qt sources so that i can debug into them. Ah, of course.

@Beemaneni-Bala Marvellous, if the solves your problem please mark the thread as "Solved".

Hi, On a side note, this line: Home* homeObj = qobject_cast<Home *>(this->parent()->parent()->parent()->parent()); Is very very nasty. You have created a very tight coupling on 4 ancestors. This is really not a good design. You should forward the signal upper and update the progress bar from your Home object but not 4 levels down in a class that should not even care whether there's something connect to it's progress signal.

@Pradeep-Kumar Do you have your code please? Sounds like you're adding nodes at the root level. You need to insert a sibling after the first/second node.

I replaced them with QPlainTextEdit textboxes and so the code: model->setData(model->index(row, model->fieldIndex("model")), ui.model_txt->toPlainText()); is not needed.

@VRonin I have changed your code to: comboBox->model()->setData(comboBox->model()->index(0,0), QObject::tr("Text")); And now it's retranslating QComboBox. I post it here so others can find the solution. Thank you for your reply.

It's a bit unclear, you built QtCreator or you installed it?

You can define an accessibleName for your objects and distribute different StyleSheets. either via the designer or QWidget::setAccessibleName(const QString &name); e.g. QPushButton{ background-color: blue; } QPushButton[accessibleName="SpecialButton1"] { background-color: red; }

Never mind, I had code in my the constructor of the to be threaded class, that caused the conflict... connect(&modbusThread, &QThread::started, modbusDevice, &Modbus::setupClass); fixed the issue.

@dheerendra Your post helped me alot and thank you for the explanation.!

Well, there's also an alternative to modifying the QCustomPlot sources, but it comes with a disclaimer. Consider this specialization: class MyType; //< Whatever your type is template <> static inline QVector<MyType> QVector<MyType>::fromStdVector(const std::vector<MyType> & vector) { QVector<MyType> tmp; tmp.d = QTypedArrayData<MyType>::fromRawData(vector.data(), vector.size(), Unsharable); return tmp; } Here goes the disclaimer: I haven't tested that, it's hacking into Qt's internals, so use at your own discretion. You have to ensure the std::vector instance will not go out of scope while any one QVector instance holds reference to the data

@jsulm well , i hope so

@Assil Without the build log (what @SGaist asked for) it is hard to say what the problem is. So, why not just post the build log?

@jsulm Thank you very much. Now I corrected the program , it is running. Thanks to all who have helped me.

You can do it styling QTreeView::branch see http://doc.qt.io/qt-5/stylesheet-examples.html#customizing-qtreeview

Hi, for an integer input between 0 and 100 set the mask to "009". Thats all.

I think you are describing exactly the functionality of KDescendantsProxyModel

I figured it out, it wasn't a stylesheet problem. I had to add slider->setFixedHeight(20) and it worked. [image: b468d3df43094208a536df84faf80c18.png]
