QtDesigner and Python

[mshemuni]

Hi everyone.
I have two problems with QtDesigner.
I'm using QtDesigner and converting file to PyQt with this code:

pyuic4 -x [input] -o [output]

pyuic4 -x [input] -o [output]

To copy to clipboard, switch view to plain text mode 

I'm adding functions to output file and make it do something.

For example I have a graphicsView and a line Edit and two buttons.
Ok. When you clicked on first button a dialog open file appears and let you select an image file to view on graphicsview.
I want fill Line Edit with my name when second button clicked. But I want to send my name as a parameter to class.
But I can't display image and sent parameter to a class. This is my code:

Sorry for bad English.

Have a look at QGraphicsScene::addPixmap()
By the way, do not change the file generated by pyuic. Instead subclass the class and add your code to your subclass.

Well. I'm a newbie.
Can you fix my code and sen it back?
So I can use it as a sample.
I think there will be two files and I must import my code file to pyuic generated file ha? But how?

I can't help you with Python code, but as Wysota said, don't touch the pyuic file. Import the pyuic generated file into *your* custom code file, not the other way around. This is exactly the same as C++ programmers do with the MOC- and UIC-generated files.

Most probably using the "import" statement

What about triggers and getting parameters from functions?
Please make a small, silly, pathetic example for me. (:

I have no idea what you mean.

I have no idea what you mean.

At first thank you very much for example.

But I meant triggers like Onclick, OnMouseMove, OnMouseDown and bla bla.
For example can you make a calculator that can print sum of two numbers.
Something like this:

calcx.py.tar.gz
calcx.py

But you said do not change pyuic4 generated file. How can I do the example above with your method?
