Subject: Added iApp::exec() function, which enters the Qt event loop and runs the application.
X-Git-Url: https://vaikene.ee/gitweb/index.html?a=commitdiff_plain;h=8958311b9f05fc65cdf9e528db8b4b32a94eb24a;p=evaf

Added iApp::exec() function, which enters the Qt event loop and runs the application.
* Sets the application ready;
* Calls QCoreApplication::exec();
* Sets the application back to not ready.
Changed main application to use the iApp::exec() instead of QApplication::exec().
