You can put pointers to widgets into arrays/lists/maps as you please and use those for iterating through them etc.

You can't get Designer to do that for you, so you have to manually populate the arrays/lists from the ui->... instance variables yourself (after setupUi()).

You can also visit all widgets of a given type, without setting anything up, via topWidget->findChildren<QLineEdit *>().

You can "group" widgets at design-time by e.g. creating a "holding" container QWidget or QFrame or QGroupBox if that helps. For buttons there is also QButtonGroup.

@Axel-Spoerl said in QtCreator debugger: display enum texts when used as array indexes, instead of 0,1,2...:

Re-translating that back into an enum, goes a long way. I doubt it will be implemented.

Which is all I said :)

@Sachin-Bhatt My explanation: True evaluates to 1 in a numerical context. False evaluates to 0. So:

True +3 = 4 1 + 4 = 5 2 + False = 2

@jsulm Thank you. That works. What could have been the problem? That C Arrays are not compatible for the container classes?

@SGaist okey i will try

Thanks guys!
Im on Qt 5.10, that explains why the "=>" is not working. Had not known about the old style syntax.

Settings this to closed.

Do you think after 6 years, he's still looking for a solution? ;-)
The topic is marked "solved" anyway :-)

@Geeva
The easies way is to move your task into its own function that expects q QList<QString> as an argument:

void myClass::myFunction(QList<QString> startvalue){ //do stuff eg: qDebug() << "Value Received from server :" << startvalue; QStringList first = startvalue.split("|"); int firstSize = first.size(); qDebug() << "size :" << firstSize; if(firstSize == 5){ first1 = first[2]; first2 = first[3]; }..........(continue) }

then you call that function for each and every item in your QList<QList<QString>>

QList<QList<QString> > myList for(QList<QString> ls : myList){ myFunction(ls); }

@Lasith
Hi
old type c array can also work.
Its just a matter of what is registered already.
You can register your own types.

@J.Hilk Thanx alot

@VRonin
i before write my code to this method 369 book:

void WeatherBalloon::sendDatagram() { QByteArray datagram; QDataStream out(&datagram, QIODevice::WriteOnly); out.setVersion(QDataStream::Qt_4_3); out << QDateTime::currentDateTime() << temperature() << humidity() << altitude(); udpSocket.writeDatagram(datagram, QHostAddress::LocalHost, 5824); }

But we want to connect UDP processing data to GUI app, it can not read QDataStream Method and it Crashs. The app is written in C#,So we should try a method that work with VisualStudio.
Agian Than kyou for attention
best regards stackprogramer

Hi @Alper,
Here is what works.
Use ScrollView instead of Flickable for scrollbars. Then as per this we need to explicitly set the contentItem as this newly created component.
A very minimal example:

import QtQuick 2.6 import QtQuick.Controls 1.4 Item { id: root width: 200 height: 200 ScrollView { id: scroll anchors.fill: parent } Button { text: "Load" onClicked: { var component = Qt.createComponent("Dummy.qml"); var obj = component.createObject(scroll); scroll.contentItem = obj } } } //Dummy.qml import QtQuick 2.6 Image { id: image; source: "http://placehold.it/650x650&text=\"Qt\"" }

@Mark81
I'm certainly not a D-Bus guru, my experience with it is somewhat limited. That said, I think QDBusReply::value can be used, provided you have registered your types.

Kind regards.

@Elg1
I don't think anyone/the OP is around any longer to answer from a thread from 5 years ago! Suggest you open your own new thread question.

@p3c0 I tried but that didn't work. Folks on Stack Overflow don't know either. I got no other choice :

@SGaist
Yes, It worked me out.
