Detailed Description

Base class for the Krita app.

This class handles arguments given on the command line and shows a generic about dialog for the Krita app.

In addition it adds the standard directories where Krita can find its images etc.

If the last mainwindow becomes closed, KisApplication automatically calls QApplication::quit.

override

Overridden to handle exceptions from event handlers.

KisApplication::notify() is called for every event loop processed in any thread, so we need to make sure our counters and postponed events queues are stored in a per-thread way.

We must pop event from the queue before we call QApplication::notify(), because it can throw!

start()

bool KisApplication::start ( const KisApplicationArguments & args )

virtual

Call this to start the application.

Parses command line arguments and creates the initial main windows and docs from them (or an empty doc if no cmd-line argument is specified ).

You must call this method directly before calling QApplication::exec.

It is valid behaviour not to call this method at all. In this case you have to process your command line parameters by yourself.
