Hi guys,
Any update about this issue? Is the idea workable?
Can you explain why should we consume right clicks but not left
ones? (May be there are other test cases when NPE is thrown... )
And why do you consume event? (May be it hides NPE but breaks
functionality)
Thanks, Pavel
1. When right clicks, it suppose to show a manu on where you
click. But I guess the demo (CodePointIM) is not suppose to show
that (what will be show when use CodePointIM and right click?
IIRC, I tried the normal input and right click but get nothing)
2. If point 1 is true, consuming the right click in the
CodePointIM is the easiest way to fix it and less error-prone
comparing with fixing in the jdk...
3. Consuming left click will disable the movement of the input
place by clicking, I guess...
There is no information about popup menu in the bug description.
The problem is that endComposition() throws NPE if Input Method is
turned on and the program is in composition mode. If you apply
your fix and change BUTTON3 into BUTTON2 in the MouseEventTest2
test (see bug description), then NPE will be thrown with your
patch as well...
Regards, Pavel
Why change Button3 to Button2? Does Button3 reflect the right click?
No, Button2 is the middle button. But if you use Button2 in the
MouseEventTest2 the test is still valid and it shouldn't throw any
unexpected exceptions. But if you apply your fix and replace Button3
by Button2 in the MouseEventTest2 test, run the MouseEventTest2 test
and use testcase from the bug description (of course in step 5 you
should use the middle mouse button now) you'll get NPE
NPE was occurred because the component is null. Component becomes
null because the default carret, IIRC, has been changed when it
receive the right click event. It is the right behavior, if I
understand correctly. So I am trying to disable the right click
event if the demo does not suppose some menu should going to show up.
I still don't understand where do you see popup menu? I wrote about
the test from
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6938583 and there
is no popup there...
Regards, Pavel
I got your point. What about this solution:
If in the compose mode, endCompositoin just sendComposedText instead
of sendCommittedText.
The patch is attached
Could you please explain the fix? May be it removes NPE but it puzzles
me. So if buffer.length() == 0 you invoke sendCommittedText, right?
But sendCommittedText commits buffer, but buffer is empty. Looks
strange...
BTW: the code like "if (!notInCompositionMode) {" a little bit
difficult to understand =) I'd preffer to avoid two negations and use
"if (notInCompositionMode)" and swap if/else blocks...
Regards, Pavel
Hi Pavel,
Sorry for the confusion. Here is some explanation, please correct me if
I am wrong:
1. There two modes which is judge from the buffer size: composed mode
when the buffer size is not zero and normal mode when the buffer size is
zero.
2. The original code make no difference whether it is in the composed
mode or normal mode. In the normal mode, which buffer size is zero, it
sends the committed text. In the composed mode, which buffer size is not
zero, it also sends the committed code. And NPE occurred here.
3. In the patch, I do not change the logic when in the normal mode.
(notInCompositionMode branch) Why? I guess it is the logic of "Ends any
input composition that may currently be going on in this context.
Depending on the platform and possibly user preferences, this may commit
or delete uncommitted text." from the api spec....
4. In the patch, the logic in the composed mode is that: if it is in the
composed mode, keep every thing as just composed :-)
