how to use signals and slots for qstring in qt

[Meera Hadid]

I have a QString name this value changes whenever the button is clicked. Now I want to call a function update() whenever the name value changes.

@Meera-Hadid please provide a minimal and verifiable example.

As @eyllanesc says you need to be more specific. However you don't use signals/slots directly on QStrings, it sounds like you want them on the button click.

[Thank You]

@Meera-Hadid

You can do something like emitting signals on your own

Create a slot , as you said update()
What causes the button text to change emit signal there ,
and it will execute things in slot

As others have said , a basic example is required for what you want
