You really should read some tutorial I found this one very useful.Import random import math import guess_the_number_GUI class GuessTheNumber : def _init_ ( self ): self. But since a QLabel has a setText slot, we could just do self.line_(self.line_tText) and not define a function. This is example shows how you can connect your own function to a slot.

Here is a full example that uses such a mechanism to copy all the text from a QLineEdit to a QLabel as soon as it's modified. QLineEdit allows users to enter and edit single lines of plain text and provides many useful editing features, including: undo and redo, cut and paste, and drag and drop (see setDragEnabled ()). To know when exactly the user changed the text, yes, you should connect to the QLineEdit. PyQt QLineEdit (textbox input) The QLineEdit class is a single line text box control that can enter a single line string. You should add the QLineEdit to a GUI, let the user do something with it and then obtain the text with QLineEdit.text(). Of course, you get an empty string from text() it doesn't work like that. You seem to be creating the object and using it right afterwards. line=QtGui.QLineEdit(self)Ī short code example would be great.

Do I need a textChanged signal to get it to update or something? I've tried adding self.line, but that didn't work either, a little rusty on object oriented programming.

This is the type of thing I've been trying. Do I need to associate it with a signal before the text will go into my variable?

I know it has to do with lineEdit.text(), but it isn't seeming to work. I'm learning Pyside and I can't seem to get text from a QLineEdit into my own method so that I can input it into a query etc.
