I was reading this post on the rhino3d website and I was having problem understanding the way the bound method as described in the post is structure, copied below:
The bound method, listed later in the calss definition is run if the button is clicked.
# Close button click handler def OnOKButtonClick(self, sender, e): if self.m_textbox.Text == "": self.Close(False) else: self.Close(True)
where does the sender and e input coming from? Do I ever have to change them and call/assign them?
self.m_button.Click += self.OnButtonClick
also on the subject, in the line above, it is explained in the post that:
an action is commonly attached through the
.Clickevent. Use the
+=syntax as shown below to bind the action to button.
I’m not an expert in Python and could not understand why +=, which usually means equal to self in addition to *, can here used to bind action to a button, which is not that big of a deal, but do I ever have to use a different syntax for button binding in a specific scenario?
Thank you so much!
