[Qt-interest] QRadioButton and toggled(bool) signal

[Robert Caldecott]

I have designed a dialog using Qt Creator/Qt Designer that contains
two radio buttons.  I have wired up the toggled(bool) signal of one of
these buttons to the setEnabled(bool) slot of two other controls on
the form, so when the a button is clicked the two other controls are
enabled/disabled accordingly.  This works fine once the dialog is
displayed and one of the radio buttons is selected, but the
toggled(bool) signal isn't emitted when the dialog is first created.
Can I force this signal to fire from my dialog's constructor so the
initial state of the related controls is correct when the form is
displayed?
