It's complicated, but basically I want to make subtle adjustments to the indentation, reformat, and test to be sure I haven't changed the vertical size of the paragraph due to wrapping. I also need to know the horizontal size of each line in the paragraph.

What is the best way to get the pixel height of a paragraph at any given point in the document? I assume this would be two steps -- 1. Get the paragraph and 2. find it's height.

Thanks.

We have need to override how wordwrapping is calculated in the document. One option might be to implement a "minimum raggedness" wrapping algorithm, like described here: http://en.wikipedia.org/wiki/Word_wrap#Minimum_raggedness -- this could solve our needs. However, ideally, I would like to be able ...

Default behavior of RichView is to break words if they are wider than the control for wordwrapping. Is there a way to prevent this? I need an option to keep long words together even if they are too wide for the width of the control. In other words, I don't want wordwrap to break inside of words.

I should add that the two controls will have the same sizes, so formatting shouldn't be necessary when the data is cloned.

I have two richviewedits. I want to clone the content of one to the other, including styles, etc, but do not want them to *share* anything (no common pointers/classes/etc).

I just discovered: Mida – now in beta - to convert a Delphi VCL application to FireMonkey: http://midafiremonkey.wordpress.com/ Keep in mind that there is no way to use this tool to "convert" a third party VCL control to FireMonkey. Its usefulness in anything beyond the most trivial of UIs is q ...

RV uses GDI for, well, almost everything. GDI is Windows. The cool thing is that they already have an abstraction layer (a graphic interface), so something else could be used without writing too much.

I need every item in the document to receive a paint message, not just the items in an invalidation rect. This is because I am rendering special effects like shadows, which can paint outside of their TextExtent. I am handling the painting myself and can deal with checing the clipping rect on my own ...

When text is typed into the editor, it seems that the entire paragraph is invalidated with each keypress. I am doing a lot of CPU-expensive custom drawing and things get real slow when a paragraph becomes more than a few words; especially when it is more than two or three lines. So, two questions: 1 ...
