Interfacing from Python to GUI

[HMartins]

I found a solution:

class PlotGUI(QMainWindow):

    def __init__(self):
        super(PlotGUI, self).__init__()
        uic.loadUi("PlotGUI.ui", self)
        self.show()

        global txt_log                     #  <<<<<<<<<<<<<< these two lines
        txt_log = self.textEdit_log  #  <<<<<<<<<<<<<< these two lines

Then a small aggregating (append + repaint) function

def txt2log(str):
    txt_log.append(str)
    txt_log.repaint()

And finnaly,

txt2log("appending text")

placed in any other function is doing the job.

Thank you
