83197 - Problems with the BiDi input widgets

Status: RESOLVED FIXED

(Core :: Layout: Text and Fonts, defect)

Description

[Ilya Konstantinov]

1. Go to http://www.msn.co.il/ (your typical Logical page)

Problem 1:
1. Select a word or two from the text.
2. Paste it into the input box (middle-click on the input box, in my case on X11).
Result: The text is pasted backwards.
Note: If I write atleast one Hebrew character in that box and THEN paste, the
direction is correct.

Problem 2:
1. Type "SHALOM hello" into the input box (with "SHALOM" being a Hebrew word).
Note: At this point, I expect the cursor to be in the end of the string.
2. Press Ctrl+U (traditionally "erase to beginning of line" on Unix widgets)
Result: Nothing is erased.

Problem 3:
1. Type "SHALOM hello" into the input box (with "SHALOM" being a Hebrew word).
Note: At this point, I expect the cursor to be in the end of the string.
2. Press END (to certainly go to the end of line).
3. Press Ctrl+U.
Result: The string "hello" remains (even though it seemed to be beyond the
cursor!) and it's reversed --> "olleh" (!).

Problem 4:
1. Type "SHALOM hello" into the input box (with "SHALOM" being a Hebrew word).
2. Press HOME.
3. Press Shift-END (to select to end-of-line).
Result: Only SHALOM gets selected.
Expected result: The whole string gets selected.

Problem 5:
Same as problem 4, just first press END, then SHIFT-HOME.
Result: Nothing is selected.

I could probably make up many more of those, but I'll stop here.

Problems 4 and 5 occur on Hebrew Windows also.

Are problems 2 and 3 specific to Bidi, or do they occur elsewhere?

Checking in the input box on msn.co.il with English-only text.
Problem 1: NOT reproduced. English text pasted correctly.
Problem 2: NOT reproduced. Ctrl-U erases whole line, as expected.
Problem 3: NOT reproduced. Ctrl-U erases whole line, even though the cursor
position is different from Problem 2 (I assume that's because of the 2 possible
insertion points in BiDi.
Problem 4: NOT reproduced.
Problem 5: NOT reproduced.

Thus, we come to a conclusion this is a BiDi specific problem.

Some of these problems have already been fixed, others will fixed if the patch
in bug 76190 is checked in.

Comment 7

[Simon Montagu :smontagu]

All cases now work correctly.

Comment 8

[Ilya Konstantinov]

Case 2 works correctly now since Ctrl-U works incorrectly on Mozilla: it erases
the whole line, while the Unix Ctrl-U erases to the beginning of the line
(leaving the text after the cursor intact).
