[Qt-interest] Block all signals of ui class

[Matthias Pospiech]

I have a widget with many comboboxes and spinboxes which all control 
settings of a device.
This device class however is however a pointer to 0 during contruction.
With the use of the 'connectSlotsByName' feature these widgets all send 
signals during startup which lead to a crash
when the device class is accessed.

Is there a way to disable all signals of all widgets in the ui class?
Setting a blockSignals(true) around all widgets before and after the 
ui->setupUI(this) does not make much sense to me.

Or can I copy the code for the connectSlotsByName feature somewhere ? 
Then I could get around setting up the connect code for all 20+ widgets.
