First : a SVG Zone is a picture.

Second : Yes you can drop something on it. You must use the event On Begin Drag Over in the listbox to fill the d&d container and On Mouse Move (to get the id of the object SVG) and On Drop (to read into the d&d container) for the picture area.

Not sure on the drag and drop, but I suspect so since it’s not a special area.

I’m not sure what the copyright issues are on the Summit databases. You might try calling your 4D sales rep and see if it’s OK to get it from an attendee.

I am very interested in using the SVG component for 4D in a GIS Project that I am working on. However, the component I found on the 4D Forum is compilied so I cannot really see how it was done. Do you have an example database that you could send me (interpreted) like the “seating chart for an arena” that you mentioned above?

Are drag and drop also supported in an SVG area? For example dragging an element from a ListBox onto a polygon in the SVG area.

I highly appreciate your comments!

Best Regards

Hello,

You said : “To get On Clicked events you have to set an ID attribute. Then you need to GET MOUSE coordinates and then pass those to SVG Find element ID by coordinates….”

No, since the 11.3, you pass the system variables “MouseX” and “MouseY” as parameters to the command. You don’t need “GET MOUSE” and substraction. “MouseX” and “MouseY” are always availables on rollover or clic events. (except for replicated picture of course). It’s magic!

A Component (4D SVG) will be available, free, at the same time that the 4D 11.3. This component gives more than 100 macro-commands to generate SVG pictures.
