I want to make a UI that carries out an action when the user presses return (think like in Pidgin), and I have a couple questions about how to do this. I've dabbled a very small amount but I'm basically a (Py)Qt newb.
From what I can tell, I want to use a QPlainTextEdit. I don't think a QLineEdit will work because I will sometimes need multiple lines, but they'll arise in ways other than the user pressing enter. (Again, think about Pidgin: enter sends a message, shift-enter adds a newline.) Looking at the signals that are available, I don't see one that says what key has been pressed. I might be able connect a slot to textChanged() then do something like figure out what the cursor is and then look at the preceding character or something like that, but it seems much better to create a subclass of QPlainTextEdit and override the keyPressEvent() (or maybe keyReleaseEvent()?) function. Does this all seem reasonable, or am I missing a better approach? Evan
