Instruction:
Here you have a function in Python 3, explain what it does
def browse_clicked(self, widget, data=None):
        text = self.gui_helper.create_file_chooser_dialog("Please select directory", self.path_window)
        if text is not None:

Response:
Function sets the directory to entry
            Function sets the text to be displayed
