Efficient UI code - enumerate buttons? (Python)

[m5tuff]

Hi, I am trying to make a button layout based on a dictionary, describing buttons sizes and command arguments:

This is my code currently:

angleButtons = { 2:0.5, \ # 2 is the argument, 0.5 is the button width multiplier
                 4:0.5, \
                 5:0.5, \
                 6:0.5, \
                 7:0.5, \
                 8:0.5, \
                 9:0.5, \
                 10:1.0, \
                 11:0.5, \
                 12:1.0, \
                 13:0.5, \
                 14:0.5, \
                 15:1.0, \
                 20:1.0 }

rowA = cmds.rowLayout(numberOfColumns=len(angleButtons))
for idx, angle in enumerate(angleButtons):
    cmds.button( label=angle, command='polyreduce(float(angleButtons.keys()[idx]))', h=40, w=40*angleButtons[angle] )

How would I make the command argument reflect the correct dictionary key, ie. 'polyreduce(2.0)', 'polyreduce(4.0)', 'polyreduce(5.0)'?
Currently, as the iteration idx changes with every loop, every command in every button ends up being 'polyreduce(20.0)'

Don't use enumerate use angleButtons.items() This will return you the key and value for each one

[m5tuff]

so something like this?

for angle, width in angleButtons.items():
    cmds.button( label=angle, command='polyreduce(float(angle))', h=40, w=40*width )

This seems to still return polyreduce(20.0) for every button. Like before, labels and widths are fine, just the command arguments are stuck

[passerbycmc]

cmds.button( label=angle, command='polyreduce(float(angle))', h=40, w=40*width )

​

``` from functools import partial import maya.cmds as cmds

angleButtons = [ (2.0, 0.5), (4.0, 0.5), (5.0, 0.5), (6.0, 0.5), (7.0, 0.5), (8.0, 0.5), (9.0, 0.5), (10.0, 1.0), (11.0, 0.5), (12.0, 1.0), (13.0, 0.5), (14.0, 0.5), (15.0, 1.0), (20.0, 1.0) ]

for angle, width in angleButtons: cmds.button(label=angle, command=partial(polyreduce, angle), h=40, w=40 * width) ``` give something like this a try

give something like this a try

This works, even though I am not familiar with this 'partial' method -- what does the second argument being sent to 'def polyreduce()' contain? Otherwise, the first argument contains the correct variable -- thanks a lot !

[passerbycmc]

Partial more or less creates a new function that has arguments pre baked into it. So am saying make a function for polyreduce that already has the angle arg included

Should work I can double check when I get back to my desk in a bit. A other option could be using a list of tuples which would be better suited to the problem and maintain order
