[banlinhtienphong]

assume,I have
connect(obj1,SIGNAL(changestatus(int),obj2,SLOT(ge tdata()));
how I get int value in signal from getdata function?

[Zlatomir]

Use a slot that has an int parameter, something like:


void CLASSNAME::getData(int inValue){
//use the value
}
//to connect use:
connect(obj1,SIGNAL(changestatus(int),obj2,SLOT(ge tdata(int))); //you only write the type at the connect statement
