Stack overflow error with signal & slots

c0d3r

I am not sure why this is blowing the stack, how can I correct this code?

VRonin

Use textEdited()signal instead of textChanged()

The explanation of why you are having this is that when you call setText() a new textChanged() signal is emitted and so on to infinity (or up to the limit of the size of the stack that then goes overflow)

@VRonin awesome, I realized I now why I was causing a new event to get fired, thanks!

@mrjj I didn't know about this handy debug helper, thanks for pointing it out :)

@c0d3r
yes qDebug() is super
most Qt classes have overloaded << for it

so
qDebug() << "info:" << someqtobject ;
works really well :)
Even lists etc.
