Hi All,
Method TreeItem#setGrayed() doesn't correct work in rap 1.3. Item doesn't change it background color to gray. In rap 1.2 all was ok.

Hi Andrew,

the TreeItem#setGrayed() is not intended to change the item background color to gray. According to JavaDoc:
"Sets the grayed state of the checkbox for this item. This state change only applies if the Tree was created with the SWT.CHECK style."
It's working as expected in 1.3 and there is no change in comparison to 1.2.

Best,
Ivan

Sorry, i made a mistake. TableItem doesn't change it background color if table was created with SWT.CHECK style.
You can see different behavior of it in demo of rap 1.2 release and rap 1.3 M3 on TableTab by pressing "Change grayed for selection" button.

Andrew,
the correct behavior of Table/TreeItem#setGrayed( boolean ) is the one in 1.3. The grayed state of the checkbox is applied only for checked checkboxes. For unchecked checkboxes there is no visual difference. This is the same in SWT too.
Best,
Ivan

Ok, thx. Is it possible to change bg color of tableItem for unchecked checkboxes without patching src ? (I'd like to have tableItem's with SWT.CHECK style which has not white bg color in unchecked state).
