Hi,
I have a editor plugin which is running into problems when folding is
enabled. If I disable folding, its working fine.
I'm trying to capture the keystore ARROW_DOWN to go to next line.
The code is as follows.
public int goToLine (int linenum) { /* I call this with linenum
(presentline no + 1) */
try {
// see that the line is in the document and get the line
IRegion line = thisdocument.getLineInformation(linenum);
int cursorPosition = getSelection().getOffset() -
getLine().getOffset();
if (line.getLength() < cursorPosition) {
cursorPosition = line.getLength();
}
mySelection = new TextSelection( myDocument,
cursorPosition , 0);
if ( myTextViewer != null) {
myTextViewer.getTextWidget().setCaretOffset(cursorPosition );
myTextViewer.getTextWidget().showSelection();
}
return getSelection().getOffset();
}
}
catch (LocationException e) {
return -1;
}
}
This code works fine when there are no hidden lines. But with folding,
not all the lines are visible. As a result, the cursor movement goes
haywire.
Any clues on how this has to be handled?
Rgds,
Ravi.
