Description Gábor Balogh CLA 2004-10-21 08:48:29 EDT 
In Text Editor or Java Editor typing CTRL+PAGEUP and CTRL+PAGEDOWN creates left 
margin if last line is longer than visible editor width and text is longer 
(vertically) than visible editor area.

Workaround: Positioning on last character in last line and typing any key but 
ARROW UP removes this extra margin.

It is reproducable always.

Please type CTRL+PAGEUP and CTRL+PAGEDOWN in the last line (at any cursor 
position).

Screenshot about result (text editor was used) attached.

Can you attach the file.
Did you install other plug-ins?
Comment 5 Dani Megert CLA 2004-11-02 10:47:15 EST 
Could not reproduce under Linux either

Test text file to get this bug

No extra plug-ins are used.
Comment 7 Dani Megert CLA 2004-11-02 13:17:39 EST 
Cannot reproduce using I200411010800
Note: to me it looks as if the file doesn't correspond to the picture attached
in comment 2.
Comment 8 Gábor Balogh CLA 2004-11-03 05:44:17 EST 
Content of test file is different than the one used at taking screenshot but 
the outcome is the same. Also in build: 200411022000

The big problem (my fault, sorry) was the key combination I wrote. So instead 
of CTRL+PAGEUP and CTRL+PAGEDOWN:

Type CTRL+HOME and CTRL+END in the last line of test text file.
Comment 9 Dani Megert CLA 2004-11-03 06:27:01 EST 
Can reproduce now. Simple steps:

1. open the attached file
2. press Ctrl+End
3. press Arrow Up
==> cheese

might be related to bug 35886

It's not just the highlighting: the widget is in a strange state where I can't put the caret on column 0.

Dragging the horizontal scroll bar brings the widget back into a good state.

Shows widget in strange state
Comment 14 Felipe Heidrich CLA 2006-04-11 12:25:06 EDT 
Test case:
public static void main(String[] args) {
	Display display = new Display();
    Shell shell = new Shell(display);
    shell.setLayout(new FillLayout());
    StringBuffer buffer = new StringBuffer();
    for (int i = 0; i < 50; i++) buffer.append("TestTest\n");		
    for (int i = 0; i < 50; i++) buffer.append("TestTest");    
    StyledText text = new StyledText(shell, SWT.MULTI | SWT.V_SCROLL | SWT.H_SCROLL);
    text.setText(buffer.toString());
    shell.setSize(400, 400);
    shell.open();
    text.invokeAction(ST.TEXT_END);
    while (!shell.isDisposed()) {
      if (!display.readAndDispatch()) {
        display.sleep();
      }
    }
    display.dispose();
}
