Re: Cursor and Caret

Hi Brendan,
1. After saving an RTF doc as XML, similar to the save method in the demo but with a few preparative actions, the cursor does not reappear and it does not reappear on mouse click either (the position is registered though and I can see something in a flash). 


I can't tell what is happening from your description. As you said,
the demo application works fine, so the obvious question is, are
the "preparative actions" affecting the control?


No, just preparing the path, moving the previous version to a backup folder and 
saving a text file. I traced the demo but I lost track there. Can you give me a 
hint?
2. After setting an insertion point by mouse click and next programmatically moving the insertion point around, the caret remains where it was initially and does not show where the insertion point position has been moved to. 


Try calling the FormattedText fullUpdate method after
setting the insertion point and then report to me what happens.


Alas, nothing. What now?
3. If the cursor is at the beginning of a paragraph, pressing the left arrow key does not move it to the end of the previous paragraph. 


This will be fixed in preview 26.


Fine!
4. How can I avoid the vertical space (approximately the size of a line height) when a new paragraph is made by the return key or programmatically? 


Every paragraph has a before and after space attribute. This is
the amount of space in inches added before and after the
paragraph. There is a method in FTDocument called
createDefaultParagraphStyle which you could override set the space
attributes. In preview 26 I have enhanced this capability by
adding an event called DefaultParagraphStyle in the FormattedText
class which you can fill in with a paragraph style that will be
used for the default setting.
That works. Great. In view of your plans with preview 26 I did not persue trying to create a new method for this purpose in my FTDocumentSub subclass.
5. I noticed that, after setting the insertion point and next, performing some actions that have nothing to do with FTC, the insertion point has frequently been repositioned at offset 0. Is this the result of an action triggered by the timer and how can I avoid this? 


Not enough information here for me to make a determination. Most
likely it is a bug in the FTC if the insertion point is set to the
beginning when it is not supposed to be. It is not likely that the
insertion caret timer or the optimization thread would cause this
behavior. When preview 26 comes out, test against it and tell me
if the problem still exists.


I shall!

Thanks a lot!

Leo
