# When the widget type starts with the word 'PM_' , the
# PM_WidgetRow treats it as a well defined widget and thus doesn't try
# to create a QWidget object (or its subclasses)
# This is the reason why qLabels such as self.warningSign and
# self.phraseNotFoundLabel are defined as PM_Labels and not 'QLabels'
# If they were defined as 'QLabel'(s) then PM_WidgetRow would have
# recreated the label. Since we want to show/hide the above mentioned
# labels (and if they were recreated as mentioned above),
# we would have needed to define those something like this:
# self.phraseNotFoundLabel = widgetRow._widgetList[-2]
#Cleanup in PM_widgetGrid could be to check if the widget starts with
#'Q' instead of 'PM_'
#Widgets to include in the widget row.
