Thank you DanJean - my serious mistake. Now it works on target. Still, mouse (and probably keyboard) doesn't work and touch screen also, however it is not matter of Lazarus, but probably regards my linux building. Program consists of form and timer which after 5sec make some label visible - works OK.
BTW I think I read somwhere that there are some constraints related to qt4 bindings. Am I right ? I so what are thay about ?
Regards
