Re: How to find first visible item in editor?
Stan! I'm really, really embarrassed! I've been programming for decades and I made the newbie mistake of getting a variable mixed up in my test routine. I was looking at bad data all along. FirstItemVisible is working now (and useful?). I found it when I was making a little demo for you. That's what ...

Re: How to find first visible item in editor?
Hi Stan, I don't have any issues with it being zero based. The problem is when line 0 (or what I am calling the first line), rve.FIrstItemVisible returns 0, but when I then scroll so that line 1 is at the top, it still returns 0. Then when 2 is at the top, still 0, then it finally starts ...

Re: How to find first visible item in editor?
This is brute force, but it might work. This gives me the item number, and where it is. I can then test it to make sure it is on the document, and as an added bonus, since I have the coordinates, I can do a little math to make sure that my linenumbers line up properly where I print them outside of ...

Re: How to find first visible item in editor?
Hi Stan, The problem is that rve.FirstItemVisible is not giving me the correct results. In the example below it should return 4 but instead returns 2. Maybe I should be looking through the paragraphs and testing if their XY location falls in the document space (not quite sure how to do that yet but ...

Re: How to find first visible item in editor?
It's just basically a simple text editor for writing small scripts for our application (like a very basic code editor). Word wrapping is turned off so every line is a paragraph. I can write the numbers beside the editor using Canvas.TextOut, but I need to know what the first line (paragraph) is so ...

Re: How to find first visible item in editor?
Thanks Stan!
It almost works. It does not seem to be consistent. If line 1 or 2 are at the top, it will still return 0, then if line three is at the top, it will return 1.
I'm trying to draw line numbers next to the editor.

How to find first visible item in editor?
Hi,
I need to know what the first visible paragraph is in a richview editor. For instance, for a TRichEdit, it would do
iFirstVisible := ARichEdit.Perform(EM_GETFIRSTVISIBLELINE, 0, 0,);
How can I get this information from a TRichViewEdit?
Thanks.

Want to make sure I am using RVAControlPanel correctly.
Hi: I just want to make sure I am using the RVAControlPanel correctly. I have a database program with three different memo fields. Each memo field uses a TRichViewEdit to handle RTF. (I'm not using TDBRichViewEdit). I have created a toolbar for each of the three memo's. (three toolbars, each ...

Hi Sergey: A user would highlight the desired portion of a web-page that they want, then copy and paste it into TRichView. If it contained any images, I can't allow them to be pasted. I am using the THTMLView and RVHTMLViewImporter. I think I found a solution though. In rvHtmlViewImport, I just put ...

I'm trying to use the technique explained here http://www.trichview.com/forums/viewtopic.php?t=5174 .... however, when i paste from HTML, the OnPaste event never fires so this code never runs. Anyone have any ...

Unmatched Brace error when using rv.LoadRTFFromStream
Hello: When I try to load the following rtf text into an TRichView using LoadRTFFromStream, I get an Unmatched Brace error..... however, the exact same string displays fine when read by a DBRichViewEdit from a CLOB field. What is wrong with the rtf string? And why does it work from a CLOB field but ...
