This question may have been asked but i cannot find any trace of the
thread. I know the question was posted on another eclipse board by
"Sascha" but theywere directed to this forum to ask. My Question...

Quote Eclipse API:
"
public void setGrayed(boolean grayed)

Sets the grayed state of the receiver.
"

I expect org.eclipse.swt.widgets.TreeItem.setGrayed(boolean grayed) to
1. to "gray out" a tree element
2. to "disable" it (no context menu, maybe no expanding/collapsing)

If I run:

System.out.println(someTreeItem.getGrayed());
someTreeItem.setGrayed(true);
System.out.println(someTreeItem.getGrayed());

the console output on WinXP is:

false
false

But this method call would not cause any of the above mentioned changes 1.
& 2.

Any ideas?

Hi,

I hope the Java doc miss leads.

TreeItem.setGrayed() should be used if the tree has been created with SWT.CHECK option.

This will grays the check box, not the whole tree item.

If u wanna to gray the treeitem, u have to change the background color ot the treeitem.

With regards

I've updated the javadoc on TreeItem.setGrayed() and TreeItem.getGrayed() to
match the more descriptive ones in TableItem.
