Hi there,
in my application i have a FOR-Loop in which i start a process x-times. When the process finishes i call the my Slot-function to show a MessageBox to the user that it has finished.
My Problem is now, that the Slot-Function is everytime called when the process finished. So when the process starts 5-times, the message appears 5-times, but the message should only appear if the process runs the 5th time (the last run).
How can i do this? Thanks for help!

Can't you Just move the message box out of the loop then?

If i put the MessageBox after the for-loop i need a mechanism to check if there was an error or not. therefore i wanted to use Signal and Slot for the process.
EDIT
i solved it. I wrote a function in which i check if there where errors with readAllStandardError and if the size of it is zero, no error appeared and the show the message box.
