Qt 5.2. QTabWidget , tabs are QTextEdit . Each tab has multiple signal-slot connections. Is this approach acceptable?

Question

Qt

That is, for each TextEdita I set up several connections to implement copy/paste/cut/contentsChanged . Will a lot of connections affect performance? I'm starting to learn, I don't know all the nuances.

Answer 1

No, this will be instant, given that the connections themselves are lightweight. With proper design, you can turn signals off and on again when the tab changes, if you are of course worried about this issue
