Blocking a signal

[Naveen_D]

Hi all,

Is there any way to block a signal from emitting?
For example, i have a signal defined in my program, which i am emitting in a function like

my class:: func xyz(){
emit abcsignal();
}
I am emitting signal based on few conditions, for some reason in one condition i don't want it to emit,
any way to prevent abcsignal from emitting ?

Thank you

Hi
Just use a normal if ?

my class:: func xyz(){
if ( condition )
emit abcsignal();
else
qDebug() << "signal not emitted";
}

Also you can use function blockSignals(true) to prevent signal from emiting.
