Eirik Bakke created NETBEANS-979:
------------------------------------
Summary: With line wrap enabled, cursor at end of line is painted
at beginning of next line instead
Key: NETBEANS-979
URL: https://issues.apache.org/jira/browse/NETBEANS-979
Project: NetBeans
Issue Type: Bug
Components: editor - Painting & Printing
Reporter: Eirik Bakke
Fix For: 9.0
In an editor with line wrap enabled, the cursor is shown at the wrong physical
location whenever it is supposed to be located at the end of a wrap line.
Instead of being painted at the end of the wrap line, it is painted at the
beginning of the following line. This causes the behavior of keyboard shortcuts
like "End" and "Up" to seem nonsensical to the user, although they might well
be behaving correctly wrt. the physical location of the cursor (the character
offset).
To reproduce:
1) Go to Options/Preferences->Editor->Formatting, select "All Languages" and
set "Line Wrap" to "After words". Click OK.
2) Create a new plain text file and open it in the editor.
3) Type some gibberish into the editor on a single line that is long enough to
be broken into several break lines.
4) With the cursor on the first break line, press the "End" key (Command+Right
on MacBook keyboards). The cursor appears to move one line down, which is
unexpected. From looking at this situation, the user would now assume that they
could press the "Up" key to move the cursor back to the previous break line,
but this will not change the cursor position (because the cursor is logically
on the previous line).
