Error: When I set style to the second line, I get IndexOutOfBoundsException

[saifalmutory]

seText is InlineCssTextArea
Here I try to set the style by selecting the first line :
seText.setStyle(seText.getCurrentParagraph(),seText.getSelection().getStart(),seText.getSelection().getEnd(),ControlColorPane.getSelectedColor());
System.out.println(seText.getSelection());
I get good results

Output : 0, 5
But when I select the second line ans try changing the color

Get Caused by: java.lang.IndexOutOfBoundsException: [6, 11) is not a valid range within [0, 5)
Output : 6, 11
and the style does not change either

Based on that error message, I believe you're passing in the wrong arguments...

public void setStyle(int paragraphIndex, int columnPositionStart, int columnPositionEnd) {}

columnPositionStart and columnPositionEnd expect to be a value x that is 0 <= x <= area.getParagraphLength(paragraphIndex).

However, you're passing in seText.getSelection().getStart() and seText.getSelection().getEnd(). This issue does not occur in the first example because the selection just happens to be the same values as the one you need (i.e. the start position is 0 and the end position is equal to the paragraph length). However, once you add another line, that is no longer the case. Your start position is in terms of the area's position, not the paragraph's position.

You should just use area.setStyle(getSelection().getStart(), getSelection().getEnd(), style)
