i writing large application , have started different design patterns write 'better code'. have started phpunit , have discovered code not testable without dependency injection, not able inject mock classes without it. i'm fine idea of dependency injection. what having issues understanding more management of dependencies in project. specifically, have made global, such database connection. now, instead of being global variable, must inject dependency - that's fine. however if have large number of function calls between instantiation of database object, , required, starts bit confusing me. doesn't make sense me each function have dependency upon database object. nor make sense me put in dependency container global dependencies , have every function in code have dependency on container. imagine number of nested function calls, follows. <?php function foo() { bar(); } function bar() { // need inject instance of databa...

in example code: class mywidget : public qwidget { q_object protected: void mousepressevent(qmouseevent *event) { qdebug() << event; event->accept(); qinputdialog::gettext(null, "", ""); } }; when click right mouse button on widget input dialog appear on screen. after click button on dialog closed , mousepressevent call again , again , show dialog. if click left mouse button or ctrl+left mouse button on widget work fine. bug apper on mac os (under windows work fine). please me avoid bug. those static/synchronous dialog functions seemed bit dubious me -- implemented recursively re-invoking qt event loop routine within gettext() call, , it's easy "interesting" re-entrancy issues when use them. (for example, if event in program delete mywidget object before user had dismissed qinputdialog, after qinputdialog::gettext() returned, program executing within mousepressevent() method of deleted m...
