widget Layout / alignment within a Box

[zinc1oxide]

Environment:

• Python: 3.6.1
• ipywidgets: 6.0.0

Hi, I'm working within a Box widget that contains Checkbox widgets.  I can't seem to find the proper layout settings to get the widgets to horizontally align.  This is what I'm working with:  (Note: I do have to keep my display: 'block' setting in order to properly display my widgets vertically).

Code snippet:

items = ['Item 1', 'Item 2 - long', 'Item 3 - longer', 'Item 4 - the longest']
checkbox_items = [Checkbox(description=name) for name in items]
container_layout = Layout(overflow_y='auto', display='block', height='120px',border='1px solid black', width='200px')
VBox(children=checkbox_items, layout=container_layout)

There seems to be some attempt of formatting by default.  The first 2 widgets within the display appear to be right aligned.  However, things seem to fall off as we increase the text length.  I don't know how to control this.

thanks.

(1) We've changed checkboxes in ipywidgets 7 to have the checkbox first, rather than the label, to be consistent with standard checkbox practices

(2) In ipywidgets 6, the label is right aligned, but a slightly longer label will push the checkbox over just a bit, rather than cut off the label. If the label is really long, it will be cut off with an ellipsis.

(3) ipywidgets 7 allows you to control exactly how wide the label is, which defaults to a single fixed width.

Do you want the actual check controls to align? I suggest just making sure your text is not too long in ipywidgets 6.

Hi Jason,

Thanks for the reply.

>>> Do you want the actual check controls to align? I suggest just making sure your text is not too long in ipywidgets 6.

I would like the checkbox  to right align.  Unfortunately, I don't have control over the text and I need to display in full.  As an FYI, they are names of people, so they really are not that long.  I certainly could cut off the text to be a certain size but it seems the alignment gets thrown off when the lengths really aren't that long.  For example, the text above "Item 2 - long" vs "Item 3 - longer" is the beginning point of where the alignment starts to change.

I could try to use ipywidgets 7 - is it available?  I just tried an upgrade and still showing 6.0.0.
