I personally like to use python to do the initial node writing, to make sure my
logic is sound and I get all my work flow issues worked out. Then if the node
is too slow I will eventually get around to make the plugin a c++ node. I also
do this for convenience too because I tend to work on all
Think of it this way, is the time you save using C++'s performance greater than
the time you would spend writing, optimizing , compiling and maintaining the
same C++ code.
The advantage to Python is that it's very easy to read, maintain, distribute,
compile and share. It's performance is good
Again, no. Its not a black and white statement like "whatever python can
do, c++ can do it better". It is also not that python is for beginners and
c++ is for large projects.
If you look around, you will see mixed examples. There are huge Python
projects out there and there are tiny command line c+
Yeah, like when you handle a deform problem, most of them are plugin i
think. I know that what Python can do, C++ can do it better. Then can i
understand it like this? Python is for scripting, solving small problem

wanna be a ch
Ya, I hope I wasn't being misleading. There are things that will require
c++ to achieve proper performance.
What I mean is that simply writing in c++ won't equal a gain across the
board.
As you put it, you can't just disregard it as an option entirely. It comes
down to profiling the code in questio
This performance increase often cannot be overlooked. If you do anything
with meshes or animations especially. Not to mention that many C++
functions are still not exposed to openMaya, but many times a C++ plugin
will do something in milliseconds but the python code could take minutes.

Thank Justin, i were confuse about it all the time.

Pyside/pyqt is not limited. At Designer is not the language. It is a tool.
This tool is more useful for c++
The things you would find missing from the python bindings are things that
are not needed in python.
Auto desk doesn't support pyqt/pyside. They support at and users have to
build python bi
Well, if it possibles, i would love to do all those UI-setup:
paint,event,drag-drop in the UI file, for convenient, also easy to manage,
right? :)

I don't think it's limited.
Just think about how many widgets you would need to serve every purpose out of
the box, you'd have to choose one out of thousand. By subclassing I can modify
it to my personal needs.
And when you become more involved in qt development you'll start reusing own
class
But PyQt is quite limited, isn't it. You can't edit the code inside QtDesigner,
many item in QtGui is not present. Just some basic form, and you have to write
it all inside after subClass.My friend told me that i should write this on C,
or using the original QT's app from nokia. Why people chose
Didn't read the docs careful again. Thank Justin, i will run a few test now
:D

I think if you did not want a parent-child relationship and just a position
constraint, then you may need to do that by reacting to the itemChange() of
the source item:

Thank for the suggestion, Sascha.
Btw, in the QGraphicsScece, can i attach an item (QGraphicsItems) to another
one?,it not like parent. More like get the item's position and attach another
one to follow it? (like pointConstrain in Maya)
