assigning a property value without binding the property

[pizarro84]

Hi, I am new to developing applications using QML and I am developing a mobile game as my capstone project for school. I recently encountered a problem with assigning values to a property: how do I get the value of a property and assign it to another property without referencing it? Thanks advance

Hello pizarro84

i will be more interested to know how you are doing it.

Other wise its quite simple item.property = anything.

yep, with properties, with Objects you would find it bit harder. You could either do it in multiline (f.ex Coordinate you would set values separately for latitude & longitude) .

Note that this might mean that some change signals might fire multiple times, and to avoid such a thing, you could also construct new objects with Qt.createQmlObject, for more information see: http://doc.qt.nokia.com/4.7-snapshot...icobjects.html

Thanks very much for the quick reply! Actually what I want to happen here is:

x = 20

y = x

I want to assign 20 to y without binding x so when x changes to 25, y remains 20. Is it possible?

i will say dont declare y as a property instead make y something as a javascript global variable and than i guess x will not update y until you explicitly do that.

Oh I see, thanks! will try that asap

I would use a signal so onForcedUpdateY you do y = x

hi well lets say that you want a=b without binding a to b there is two ways (1) if you want to make a=b in a signal (clicked for examble) you say"onclicked:{a=b;a=a} ” a=a will breack the binding right after giving a the value of b (2) if you wanted to make a=b in the start you say "a:b ; Timer{running:true;repeat:false;interval:1;ontriggerd:a=a}
