Sorry, email sent accidentally. Elaborating: if "a" changes, the
engine *might* do a topological sorting of a's dependencies to
minimize the number of reevaluations. But I would never ever rely on
such a thing being present and consider it an implementation detail.

That's strange. For me it results in onPerimete

Hey guys, first of all, I've been an active member in #qt and I appreciate
all the help I've received from the guys in there. I started Qt a couple of
months ago for a new project and I could not have got this far without
everyone's help. I am very grateful.
I'm hoping for a little bit of a code r
For me even your second example calls onPerimeterChanged only once.
It seems that Qt is smart enough to only notify once when it's evalating an
expression (that's actually a js function).

I'm not sure what is going on. I just connected a Nexus 6 and tried to deploy
to it. This is an existing project that worked on my Note 2. I'm not sure if
this is Qt, Creator, androiddeployqt or what.
Help?

Hi all
I want to understand how redundant QML property binding evaluations are
mitigated. Does anyone have a high level idea of how this might be done?
Consider the following case of properties describing a triangle:
Item {
property real a: 2;
property real b: 3;
property real c: Math.s

hi,
I wanted to host a WPF user control in my QT application.
So I created a CLI dll that returns the HWND of the user control. It
creates an HwndSource for the WPF control and returns the handle of that
HWND source.
I added reference to this CLI dll from my QT application and tried to get
the HWN

Thanks for the information,

QT += axcontainer to my .pro solved the issue and I can use the ActiveQt

why Qt documentation suggests to build ActiveQt static lib
Hello Matthew,
thanks for reply.

Your solution for qt 4.7 is right for share resource (I would like share vbo

Can you link a qt example or documentation?
