Re: [platform-swt-dev] StyledTextContent

[Bahadır Yağan <bahadir.yagan@xxxxxxxxxx>]

Hi,

While reading the DefaultContent implementation, I tried the situtation 
that I described below using DefaultContent.
Here is the code:

styledText.append("test line1\r\n");
styledText.append("test line2\r");
styledText.append("\ntest line3\r\n");

The widget shows two line breaks between "test line2" and "test line3". 
And if I try to delete that extra break(by user input):

should I enter a bugzilla report or is it my fault splitting the delimiter?
