This forum unfortunately looks near to dead - 5 - 7 messages per month, 5 clicks and you are back in 2004. Does it mean that nobody uses the GUI Designer? Or everyone is entirely happy with it? We've bought version 6 mainly to use the GUI Designer. It looks now that we were too optimistic. While definition of simple form is relatively easy and enjoyable, it's hard to integrate the GUI Designer into our existing environment. GridLayoutManager is another grid layout to learn - behaving sometimes in strange and unexpected way, especially in combination with other layouts. Custom creation (use of non-default constructors) is limited. The bugs, which a critical for us (IDEADEV-11905 and IDEDEV-12679 namely) will be fixed only in next major version (why?).
In general, our expectations have been replaced with disappointment - it looks like the GUI Designer developers lost interest in their creature some steps before it will become really useful.
I would like to hear your opinions, dear colleagues.
