could you please post a swt only snippet that reproduces this problem ? what a version of mac osx are you running ? I would like to know why this NPE is happening. This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. If the bug is still relevant, please remove the "stalebug" whiteboard tag. |
I came across this when I roll up in a tree when the first item was already visible. Mac the sort of makes an elastic movement showing an empty area above the first item in the tree and the immediately bounces back to show the first time. I have paintlistener and in this paintlistener I do this: try { // Stop the sidetable from flickering sideTable.setVisible(false); // Calculate the current visible top and bottom indices in the // main tree. int itemHeight = tree.getItemHeight(); Rectangle clientArea = tree.getClientArea(); int offset = tree.getTopItem().getBounds().y; } finally { sideTable.pack(); sideTable.setVisible(true); } The call to getTopItem results in an NPE and a subsequent crashing of the complete VM. When I check on null from getTopItem everything is ok. Seems like the paintlistener is not happy with uncaught exceptions like this? java.lang.NullPointerException at
