Re: [udig-devel] ArrowSelection

[Jesse Eichar <jeichar@xxxxxxxxxxxxxxx>]

The tool extends SimpleTool which uses the normal eclipse drag and drop mechanism.  Whatever is "currently selected" is dragged and dropped.  I have added a framework recently so the currently active tool can provide the mapeditors selection.  So you can have you icon be the selection in the map editor and if your tool extends SimpleTool it will automatically drag and drop it.

Hi!

The ArrowSelection class says it handles the selection and dragging of a single feature.
I have looked at the code and cannot see how the Dragging is handle.

I have a tool and as part of that, I want to allow drag and drop to move my icons around (points), regardless of layer etc.

I find the current way of selecting a layer,  changing to the selection tool to select the feature, then changing to the Edit point tool to drag and drop the point really cumbersome. Beside which, it does not move the icon when you drag and drop, only the point, which looks odd.

So in my tool I don't want my user to have to worry about any of that.
I just want them to press the mouse over an icon and drag and drop.
I will figure out which feature on which layer they are over etc and then allow the move and commit it for them.

I just cannot figure out how the current Edit Point tool is doing the drag and drop.
I have been hunting around the code for a couple of hours.

I give up.

Help.
