Which OS(es) are you targeting?
On Windows, the general guideline is to left-align labels; on Mac,
labels should be right-aligned. These are guidelines, of course, and not
hard-set rules, but software tends to look more polished when it follows
the visual styles of the OS on which it runs.
Here's my question:
On a similar topic, what about buttons? Apple guidelines say to right
align the function that is mostly used (unless it is going to cause the
user to lose all their work), but on Windows it's the opposite. Has
anyone read or conducted a study that proves that buttons should be
"Cancel | Save" or "Save| Cancel"?
It seems that the way we have worked around this problem is to color the
button that will be mostly used as well will be committed upon hitting
the "enter" key for both platforms.
