Probably the word "draw" caused a misunderstanding... This "rectangle" is created by the user with the mouse, clicking the left button of the mouse somewhere on the map, dragging the pointer and releasing the button.... In other words, the user (not me in the code) select a portion of the map and the program has to underline the objects that are inside the selection (and other things with them).

 

Thanks again!!!

Hello Davide,

 

I'll assume you know Java. Use the drawing layer (see Demo) to draw an "OMThing" In your case, you draw an OMRect. Now, with your list of objects in hand, check each one to see if it's inside the OMRect. Using getWestLon, getEastLon, getSouthLat, and getNorthLat (these define the OMRect's bounding box), test each of your object's lat and lon to see if they're inside the bounding box.

 

The first step in this process is to create your own drawing layer and have control over the OMRect that you draw.

 

I hope this helps.

Hello everybody! My name is Davide and, as you can see in the signature, I'm writing from Italy; I joined this list some minutes ago and obviously... I have a question about the library.

I have to represent some objects over a map and, for this, I'm implementing a class like in the example MapBean provided with the code. After that, I have to select some object "drawing" a rectangle over the map with the mouse.... Like a normal selection of a portion of an image, I "draw" this rectangle to select all the objects that are into this rectangle. Is it possible? How?

 

Thanks in advance and... excuse my bad English!
