Signals and Slots across different classes (Qt5 Version)

Ah thanks didn't see that. Ok implemented that however the same error is also occurring for Setvalue.

Same mistake again. Parentheses.

Cheers,

Yes, sorry. I haven't switched over to the Qt 5 style of connect(), so I goofed on the syntax. Should have been obvious C++ that the expression for the address of a member function doesn't contain parentheses.

connect(counting, &counter::Increment_Count(10), ui->progressBar, &QProgressBar::setValue());

In any case, even if you used the old SIGNAL() and SLOT() syntax for the connect() statement, you can't pass in a value as you apparently are trying to do here. The macros are simply the signature of the method with only the parameter types, no variable names or values. The return value is assumed to be void and is ignored anyway. So the equivalent SIGNAL / SLOT version of your connect() should be:

connect(counting, SIGNAL( Increment_Count(int) ), ui->progressBar,SLOT( setValue(int) ));

connect(counting, SIGNAL( Increment_Count(int) ), ui->progressBar,SLOT( setValue(int) ));

Ok brill thanks guys, yea I am very new to signal and slots so this was a bit of a crash course for me, so didn't want to bother learning the old method. Thanks guys
