Compile one file in QT Creator

Question

How to compile only one file from project in QT creator. Is there a hotkey? For example in VS you can press Ctrl F7 and compile your current cpp file.

Answer 2

Normally if you hit CTRL + B, Qt Creator will call make, which will in turn compile any files that have been modified since you compiled the last time. AFAIK there is no designated key for re-building the current file.

However, all Keystrokes can be configured in the application preferences General -> Keyboard. There are also a number of interesting other commands you might find useful.
