Signal Sigsegv Segmentation Fault

Detailed Description. QObject is the heart of the Qt Object Model.The central feature in this model is a very powerful mechanism for seamless object communication called signals and slots.You can connect a signal to a slot with connect and destroy the connection with disconnect. To avoid never ending notification loops you can temporarily block signals with blockSignals. Segmentation Fault happening when trying to pass objects by reference in qt program Tag: c, qt, segmentation-fault, pass-by-reference I am using qt and have made it so that two dialogs appear before my centralwidget.
