I constantly find myself with options like...<br>a) create a connection from foo's custom signal to bar's slot.... or<br>b) when creating the foo object, give it a reference to bar, and instead of emitting a custom signal, just call bar's slot directly.<br>
<br>What is more lightweight.... an instance variable or a connection?<br><br>I'm sure this must be common.<br>Are there guidelines to use, rules of thumb etc?<br><br>Thanks,<br>~Eric<br>
