Question

I’ve a method triggered when a NSTextField looses focus. This method displays a popup sheet over my current window.

Everything works great except when I’ve typed something in the text field and successively I close the window by clicking on the close button. In this case:

• the text field loses focus and the method is triggered and it shows the popup

but

• the window is dismissed anyway, because I’ve clicked the Close button, so the popup is visible only for few seconds.

Thanks

You should create an NSWindowDelegate and implement -windowShouldClose: to return NO if the popup is visible or if the text field was the previous first responder (or however else you’re determining that the text field lost focus).
