Hi List,
It's me again with some QML related questions. I'm trying to call a
function in my Python code from QML UI. I followed the example called
"qmltopy2". It works OK. But I wanted more functions with the same input
parameters. I thought I only need to write a new function and then call
it from QML. But apparently this doesn't work. Please see my modified
version of the qmltopy2 example.
Is this a bug or is the behavior intended? If it's intended, how to do
it right?
val2() *must* be declared as a slot to be visible on QML.
Thank you, now it works fine.
And talking aout calling Python functions from QML, what about the other
way - calling a QML (JavaScript) funcion from Python? I studied the
pytoqml1 eample. It shows how to call a function of QML root object. How
do I call functions of other objects?
You do it the same way you do to call javascript functions from C++.
I'm sorry for my ignorance, but unfortunately I have no knowledge of
C++. Could you give me a short code sample, please? Thank you.
The example (a unit test from pyside) is attached, just replace the
adjust_filename function by nothing, i.e. just the QML file name.
Thank you, I understand it now better. But still I don't know how to
call a function of other then root QML object. For example if I modified
the QML (please check the attachment), how would I call the
"returnFunction()" now? Thank you.
