"things happen behind the scenes which can be hard to find" In my experience this holds true for *any* component based, drag-and-drop development approach. DevArt components are no different in this respect than any other framework.
That, and the fact that program behaviours are driven, sometimes subtly and sometimes significantly, by minor variations in component properties that are immeasurably more difficult to discover than changes resulting from difference in actual code, is why I avoid using such frameworks for application development like the proverbial. You can create an app that works (or seems to) very quickly. But when problems arise or you need to change or extend the behaviour or implement something which doesn't fit with the way that the components you are using expect or intend you to, the effort involved (and unintended side effects arising) then can be disastrously disproportionate. imho ymmv On 25 June 2015 at 22:41, Marshland Engineering <[email protected]> wrote: > Hi chaps and update.
