Is this a bug on TCalendar control? Please, check out the attached animated gif.
Cute. Now what are you trying to demonstrate?
When changing the component properties, its size changes, and grabbers (dots for resizing) show the old size, and the component is not clickable in the expanded area.
I can reproduce in
Lazarus 4.0 and in
trunk. With and without the
DockedFormEditor package.
@AsleyCruz, can you create a report on the
bug tracker?
