Creating a Custom Dialog, and Returning Multiple QString's

[c_07]

Thank you! I didn't know that. Problem solved.

For future reference, though, how would I use pointers with class constructors to pass data back and forth, from the class that generates the information wanted back to the caller that created the class and wants that information?

you can provide some bool flags or even status function, which will describe the child object' state.

simple example:

enum State
{
 Idle = 0,
 Running,
 Error
};
 
int currentState(); //returns current state from State enum
 
State _state; //variable for storing current state

enum State
{
 Idle = 0,
 Running,
 Error
};

int currentState(); //returns current state from State enum

State _state; //variable for storing current state

To copy to clipboard, switch view to plain text mode 

then you can check child' state or even block parent object waiting for state changes.
for example

ChildObject obj;
obj.run();
 
while(ChildObject::Running == obj.currentState)
 qApp->processEvents();
 
...

ChildObject obj;
obj.run();

while(ChildObject::Running == obj.currentState)
 qApp->processEvents();

...

To copy to clipboard, switch view to plain text mode 

and another Qt-styled solution is using signal-slot connection, which is of course the best one.
