Hi
I am sorry if this have been asked before :)
I am trying to learn using python and pyqt using ERIC 5.1.2. I have a
problem with signals and slots. I tried this on 2 different computer
with different OS and different version of python. My problem is
this...
I am creating a "test" project using Eric ... using one of the
tuturials on Eric's webpage. I create a project and a form, then i add
a push button. I save the form and i generate the form into code using
Eric I also generate dialog code and adding a slot for my push button.
So far i have not written a single line of code. In my slot i write a
print("Hello"), My only self written code. When i run this, i get a
window with my button but when i click it nothing happens. When have i
done wrong? How can i get my button to execute the slot?
thanks for the help ... sorry if this is a stupid question ;)
Here is the code:
