So, a few things have come up recently and I'm not clear how best to
achieve these things. Any pointers would be appreciated:
* Is it possible to make the map update/fully re-render as it's being
dragged with the mouse, as opposed to only when you let go?
* Speaking of mouse input: I'm reading the developer guide, and I don't
really "get" how to actually implement a mouse listener. Examples
of things I'm currently trying to do:
- I have a layer that is made up of a series of points [OMPoint],
connected with edges [OMLine]. I want a user to be able to click
on the map [or only on a node], and have the nearest node to
that point be "selected", then drag the mouse around the map [not
necessarily clicking] and run an algorithm for my graph, highlighting
the best path along my graph to get from the original point to
the nearest point to the current mouse position. My algorithm is
fast-ish, but not quite interactive-real-time fast.
- I have a map of the world being shown as a shapefile [the one included
with openmap, actually]. User clicks on a country, I want to
highlight that country.
* If I had a FORTRAN program that runs at the command-line, and I wanted
to add features to that program to have it render to a map as it
runs... how would I go about doing that?
- Is it a better investment of time to give up on that and find
something, anything, else to do? This is just a blue-sky idea...
Cheers!
Gary
