Existing Qt applications should require no porting provided there is no platform dependent code.
| Platform Dependent Code |
|---|
| Platform dependent code includes system calls, calls to the underlying window system (Windows or X11), and Qt platform specific methods such as QApplication::x11EventFilter().
For cases where it is necessary to use platform dependent code there are macros defined that can be used to enable and disable code for each platform using #ifdef directives: |
