qtablewidget bug?

Hi,

i'm using QTableWidget which contains QWidgets on different rows.
i'm setting them with setCellWidget.

problem:

for QTableWidget I can receive mousePressEvents and mouseMoveEvents always at any position of table. when mouse is on cell widgets and on empty area.

But it receives mouseReleaseEvent only when not on cell widget's area(empty area).

I don't have any event functions implemented in cellwidget classes
which could prevent events.

why mouseReleaseEvent isn't always passed for table?
