I have a dropdown box. And i want to do this when this item is selected, and that when another item is selected. So i need a way to retreive what is currently selected in the dropdown menu.

The dropdown menu is a EnumProperty. Like the dropdown box to change the rotation mode.

bpy.types.Scene.enumprop = bpy.props.EnumProperty(items = item_cb)
...

layout.prop(scene, 'enumprop', text='Files')

How do i retreive the value of the current selection from a dropdown menu by code?

  • $\begingroup$ Looks good. How your callback looks like? What exactly is wrong with this? From the API: update is called when this value is modified $\endgroup$ – p2or Oct 22 '16 at 17:19
  • $\begingroup$ @poor, The callback was exactly my problem. I had initially no idea how to do it. But i have meanwhile solved it. See answer below :) $\endgroup$ – Tiles Oct 22 '16 at 17:28

    $\begingroup$ I'd avoid update, that's why I posted the API quote. $\endgroup$ – p2or Oct 22 '16 at 18:31
  • $\begingroup$ Yes, that's what i did in the end then :) $\endgroup$ – Tiles Oct 22 '16 at 18:34

The solution was to add a update to the prop. Then i can retreive changes from the dropdown box.

def myindex(self, context):
    print('changed to,', context.scene.MyEnum)
...

bpy.types.Scene.MyEnum = bpy.props.EnumProperty(items = item_cb, update = myindex)  

Another way goes directly across int(context.scene.MyEnum). Then i don't need the update.
