I've done something similar to this and I just used a transparent layer with a border.
In a nutshell, I created a base layer (Map). The Map layer listens for onmousedown events and will create a (MapArea) layer . As the mouse moves, the MapArea is resized. When the onmouseup occurs, the size of the MapArea is set. Really wasn't too difficult - thanks to the DynAPI. I've seen some other traffic on the newsgroup about 'rubber banding' - you may want to search the archives. - Abre -----Original Message----- From: DCT Jared Smith [mailto:[EMAIL PROTECTED]] Sent: Monday, June 24, 2002 11:24 AM To: [EMAIL PROTECTED] Subject: Re: [Dynapi-Help] can dynapi2 do this? It'll take a little bit o'code, but I know JavaScript will render it quickly enough that it will not 'seem' like you're drawing four lines. You'll be creating four layers, one pixel wide. Make a function that takes an upper left coordinate and a lower right coordinate, and adjusts the length and position of four layers. The layers are 1 pixel wide, and their length depends on the coordinates to the function. Then, in your dragEvents, simply call that function with the beginpoint and the current coordinates of the mouse. The four layers will update to make the box 'enlarge' or 'reduce' quite nicely. As for the X marking a click-down event, that should be relatively easy, either with a transparent GIF or with two criss-crossed layers of 1 pixel wide, 10 pixels long. That's how I'd do it. Does anyone know how to create a transparent layer, the border of which would be your bounding box? That would take less code. -Jared ------------------------------------------------------- Sponsored by: ThinkGeek at http://www.ThinkGeek.com/ _______________________________________________ Dynapi-Help mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dynapi-help ------------------------------------------------------- Sponsored by: ThinkGeek at http://www.ThinkGeek.com/ _______________________________________________ Dynapi-Help mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dynapi-help
