};

can anybody help me?


note: i'm using Qt Creator 1.3.1 based on Qt 4.6.2

You probably forgot to implement the slot. Maybe you wanted it to be a signal and not a slot? The name seems to suggest so...

rerun qmake and all should be fine. (In the menu clear all etc.)

hi Lykurg
still error what to do?

hi Wysota

ya name seems like a signal

but i have created a process using QProcess object and when it finishes i want to call this slot.
without wriiten anything in public slot:
it works fine but when i write void procFinished(); in public slot:
it is giving error that i mentioned.

But did you implement the slot?

Slots require code in both the .h and .cpp files. Paste the code you placed into the .cpp file.
