A Paragraph represents text that has been laid out, or composed, in some container. text A Text with encoded per-character emphasis. textStyle A TextStyle with font set, line height and horizontal alignment. firstCharacterIndex The starting index in text for this paragraph, allowing composition of a long text into a number of containers. container A Rectangle or TextContainer that determines where text can go. lines An Array of TextLines comprising the final layout of the text after it has been composed within its container. positionWhenComposed As its name implies. Allows display at new locations without the need to recompose the text. Lines are ordered vertically. However, for a given y, there may be several lines in left to right order. Lines must never be empty, even if text is empty. Notes on yet another hack - 5 Feb 2001 We really need to clean up #composeLinesFrom:to:delta:into:priorLines:atY:!!!!!! I added one more habdful of code to correct: This is an annoying bug that's been around for a couple of years, but I finally figured out how to duplicate the problem, so I figured I'd just report it now. (It doesn't necessarily have to be fixed for 3.0 if it looks messy, but if it's a simple fix, it would be worth it.) In Morphic, if you have the following text in a workspace: This is line 1 This is line 2 **and** you have a return character after line 2, you will normally be able to click the mouse two times below line 2 in order to select all the text. If you edit line 2 (e.g. so that it reads "line number 2"), you can still select all the text by clicking below the second line. However, if you edit line 1, you will not be able to select all the text from the bottom in the same way. Things get messed up such that the last return character seems to be gone. In this state, if you position the cursor immediately after the 2, and press the right arrow, the cursor jumps to the beginning of line 2... oof. (report by Doug Way) While I don't have a very deep understanding of the above mentioned method, I was able to determine that text ending in a CR worked better in the editor when the last entry in <lines> had a start of text size + 1 and a stop of text size. I have accordingly added code near the end to ensure this. It seems to have fixed the problem, but we do need to clean this baby up some day. - Bob !
