Description Serge Démoulin

2011-07-22 09:52:12 EDT

Build Identifier: 

I tried to make a graphical light List.
The component behaves like a List but is in fact a multiline Text (see attachement). If the user click inside a line then the entire line will be selected. 
In some case (probabily because of the german special characters) the selection doesn't works correctly : the line is not entirely selected or another line is selected. See the following example :

CONTENT =
aaaa
bbbb
cccc
ddd dd [ERF]
eeee
ff ff
äöpödso2sdsdsd sdsdsdsdsdsdsd
äöppsdsödkmsopierjkw pewü
abgv

behaviour :
If I click on the first to the 7. line the entiry line is selected (see Remark 2).
If I click on the 8. or the 9. line only "äöppsdsödkmsopierjkw pew" is selected.

Remark:
1. under Firefox it works fine. 
2. under IE I have to consider that "\n" takes 2 places !

Reproducible: Always

Serge, without looking in deep in your code, I want to let you know that widget subclassing is illegal in SWT (will be illegal in RAP too - see bug 333272 ). The Text widget JavaDoc states that: "IMPORTANT: This class is *not* intended to be subclassed."

I know but it is only a quick&dirty test class and since I'm not overriding any method I guess it doesn't matter. It is not the cause of the problem.

I can reproduce it with your snippet, but currently I have no idea what is the reason for this weird behavior.

I guess the first cause is that this special characters are coded on 2 bytes instead of 1 byte.

This is not an issue in IE9 (standard rendering), but I still can reproduce the problem with IE8 (1.5M6).

Patch to reproduce in controls demo

I've added a patch to reproduce the problem in the controls demo (text tab).

The error occurs when you enter multi-line text with style MULTI enabled.
If you select something in the first line e.g. from 1 to 2, the text widget selects from 0 to 1.
If you do the same using the mouse and then leave the textfield by pressing TAB and then reenter the textfield by pressing SHIFT-TAB the selection shifts one character to the left

This is reproducible on version 2.0 and 2.1 with IE8 but not IE9.

The IE7/8 support is discontinued in RAP 3.0. Close as WONTFIX.
