qml dummy property
-
Hello,
I'm interesting into qmlscene.
In project I use:engine.rootContext()->setContextProperty("PP_IP", QVariant("192.168.100.195"));
to set device IP adress.
And in QML:
Component.onCompleted: { console.log("Test from example: "+PP_IP.time) //this is for debug console.log("Test: "+PP_IP) //this is what I need }
Now I want use dummy data to set PP_IP when I running qml in qmlscene.
So I created file dummydata/PP_IP.qml
In this file I haveimport QtQuick 2.3 QtObject { property int time: 54321 }
Like in example , OK it is working.
But I need print variable PP_IP not PP_IP.time.
What I have to change in "dummydata/PP_IP.qml" ??
Thank you very much -
@poucz said in qml dummy property:
Component.onCompleted: { console.log("Test from example: "+PP_IP.time) //this is for debug console.log("Test: "+PP_IP) //this is what I need }
You cannot access the object in 'PP_IP.qml' file as
PP_IP.time
.
You must create an instance first, e.g.PP_IP { id: pp_ip }
Then use the
id
to print thetime
:console.debug(tt_ip.time)
As for giving the context variable
PP_IP
the same name as your QML type defined by 'PP_IP.qml', that won't work either.
The context variable's name gets masked by the Type name.If you want to use both, give them different names.

Thank for your reply.
Sorry maybe I describe my problem wrong, or I don't understand your answer.
I set contex propertyin C++:
engine.rootContext()->setContextProperty("PP_IP", QVariant("192.168.100.195"));
When I run my program, and show "mypage.qml" - everythink is OK - console log IP "192.168.100.195" .
Now when I use qmlscene to show "mypage.qml" , the property PP_IP is not set (because C++ code not run).
So I want set these variable by dummy data. How can I do this?I need print IP adress 192.168.100.195 - when I run mypage.qml from qmlscene.
Can you post dummydata/exmaple.qml for me?Thank you for your patience!!
//mypage.qml Rectangle{ Component.onCompleted: { console.log("Test: "+PP_IP) //print IP adress } }
