Hello everyone,
I have a UI application and I need to display context menu according to whether user clicks inside a polygon or not. So, I think I need to use some algorithms which can check whether a point is inside a polygon.
Does anyone have any ideas or reference materials?
thanks in advance,
George
Something tells me you didn't search for anything on the topic.

Give up trying to be a programmer would be my suggestion.
If you can't click on a link, scroll down to where the source code is listed, and use it, then there really is no help for you.
If you want better help, then your question needs to be a hell of a lot more specific than it is at the moment.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
Well George, you're either stupid, or a liar. Here is one search engine's results for your exact keywords. Here is another search engine's.
Also, there's been at least one other thread in recent memory on this very forum, for the same concept / topic.
You need to learn how to make an effort. You do know that you're allowed to try more than one combination or variation of keywords in a search engine. Search engine's aren't like parachuting. If you ........ up, you can try again.

Really, I thought they just knew what I was talking about?
