While it may be relatively simple to know the x,y position of a mouse click, there can be multiple DOM elements that all overlap at any given x,y location, so it is somewhat more difficult to figure out which element the user actually thinks they are clicking upon. Unfortunately, even if a specific clicked-on element can be identified, finding "the matching line" in the tiddler soruce is really hard. Basically, the TW rendering engine, wikify(), is a one- way translator: it processes wiki syntax and macros and then renders one *or more* DOM elements into the current tiddler display. For example, if you've used <<tiddler>>, <<tabs>>, or <<slider>> to transclude content from another tiddler, the rendered output will have numerous DOM elements that aren't even defined in the current tiddler source. Thus, there isn't always an unambigous one-to-one correspondence between the rendered content and the current tiddler source content. There are also lots of plugin-defined custom macros that can generate multiple DOM elements that vary based on the macro's parameters. As a result, it's nearly impossible to determine a match between a given clicked-on element and some corresponding macro instance... and, even if it were possible, I expect that the code to do it would be ridiculously complicated. sorry. -e Eric Shulman TiddlyTools / ELS Design Studios --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
