Picture hotspots
« on: April 21, 2018, 06:44:22 pm »
Do we have for Lazarus some code or component to work with clickable regions or hotspots in pictures? For example to click the regions of a country.

Might be more than you need, but this is the sort of thing one does with GIS and mapping.

How free shaped you want it to be? Can you accept a number of rectangles? eg adding various TShape controls on top of the image and reacting based onwhich tshape you clicked? or do you need something more accurate? I remember there was a THotSpotImage component for delphi floating around the net but I never had the need to test it out.

@taazz I'll try that, it could be just what this little project needs.

@Phil: Seems powerful allright, but overkill this time.  :)
