/ Guidelines: Base control elements / Radio buttons

Radio buttons

Example 1:

GOOD: 

--- When closing notebook LID ---
(*) nothing
( ) suspend to SLEEP_S1
BAD:

If more options then radio-buttons occupy too much space and should be replaced with combo-box 

--- When closing notebook LID ---
(*) nothing
( ) suspend to  SLEEP_S1
( ) suspend to  SLEEP_S2
( ) suspend to  SLEEP_S3
( ) suspend to  SLEEP_S4
( ) PowerOff

  • + all options are visible
  • - occupies space

Exception:

  • You can use many radio-buttons if this group box is used often so user can select option faster.
GOOD: 

--- When closing notebook LID ---
combo-box:
 [ suspend to SLEEP_S3 ]

  • + compact form
  • - to see all options users should move mouse and click
