@ambershark said in How to add one parameter to the clicked SIGNAL?:

@aha_1980 That sure does do what he needs, lol. I didn't know about QSignalMapper.. It's funny that even after 16+ years of Qt there's still classes I don't know about. :)

I only knew it because I had the same requirement as @ChristianMontero some time ago :)

@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); }

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

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.

@AthanD
actually IMO i believe the grid layout is the most complicated one offered by Qt :)
All the others are pretty much straight forward.

But since you anyway want to display them in a grid it's your way to go ;)

@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.

@ealione
The good thing is that typically users do not notice. The problem is popping up when trying to compile with older compilers or you remember that such stuff was not possible in the past.
As @mcosta suggests there is probably a recommendation out. On the other compiler versions are changing too rapidly and also the versions of recommendations.
