Arcpy

In this practical, we'll convert the code we have so far so it runs as an addin. Make yourself a new directory m:\GEOG5790M\practical3\addin in readiness.

First, work your way through the ESRI addin tutorials, using their code to build a "Hello World" button addin:

• What is an addin? (basic intro: download the wizard – you can unzip it to any directory; which is what they mean by "install")
• Essential concepts (key things to be aware of going forward)
• Creating an addin project (make your first addin project)

  Using the following inputs for your project:
  Working Folder: m:\GEOG5790M\practical3\addin
  Select Product: ArcMap
  Name: Explosion Addin
  (Other elements as you feel)

• Creating an addin toolbar (make a toolbar for our addin)

  Using the following inputs for your toolbar:
  Caption: Model Toolbar
  ID: addin_addin.modeltoolbar
  Show Initially: Tick (this makes it a "premier" toolbar, which is automatically shown on startup. If it disappears you can show it under Customize menu -> Toolbars)

• Creating an addin button (make an addin)

  Using the following inputs for your button:
  Caption: Explosion Assessment
  Class Name: ExplosionButtonClass
  ID: addin_addin.explosionbutton
  (Other elements as you feel)
  And the following code for onClick():
  pythonaddins.MessageBox("Hello world", "Hello")

• Testing an addin (add the addin to Arc)

  Double clicking their build file should work in our lab, but if not it needs running with Python 2 (see last practical for how to do this).

Also, for information useful later, check out:

• The pythonaddins module
• Sharing addins

Starting with this button, we'll now adapt the code to run our model from the last practical.
