Could anyone give an example on how to use the ShapeEidtor plugin of dotspatial? I've searched and tried, but failed to use it. How to add the shape editor as a toolbar? How to edit the editor tool? Please give me some example code? Thanks a lot!

If you are talking about ShapeEditor...

See http://www.mapwindow.org/downloads/documentation/dotspatial-1.0/Index.html and

How to Load DotSpatial Extensions Into My Toolbar

Jul 25, 2012 at 7:21 PM

Hello,

I, too, am unclear as to ow to add the ShapeEditor toolbar.  I am using Visual Basic.

I have added a reference to the DLL.  I have "Imports DotSpatial.Plugins.ShapeEditor" at the start of my form.

The documentation that you linked to does not help me understand what to do, as I do not know where to begin.

I have successfully loaded the Measure tool, so loading plugins is not the problem, I don't think.

Thanks!

Hello,

Again, I truly would appreciate some guidance about using this extension.  As it stands, my project is currently stalled.

Thank you!

You won't have to add a reference to an extension to use it. Just drop the dll in your plugins folder. See https://mudnug.wordpress.com/2012/04/17/composing-an-application-by-using-extensions/
