Section 9. Pull Downs and List Boxes
Pull downs are edit fields that have a pull down list attached to them. List boxes look like edit areas, but cannot be edited and contain a single element on each line of the box. This section provides ideas about what to test in using pulldowns and list boxes.
- Do all the pull-downs in the program have the same background color?
- Can you pull the list down with Alt-down arrow key?
- Can you pop the list up with Alt-up arrow key?
- Is the highlighted item selected when the Alt-up arrow key is pressed?
- Can you pop the list up with the Escape key?
- Is the highlighted item selected when the Enter key is pressed?
- Are disabled pull-downs absent from the tab order?
- Is the pull-down labeled as to purpose?
- Are the pull-down labels consistent with the pull down labels in the rest of the program?
- Do all pull-downs lack hints? They should have prompts instead of hints.
- Do all the list boxes in the program have the same background color?
- Are the list boxes in the keyboard tab order?
- Do the list boxes all have a vertical scrollbar?
- If the information presented in the list box is longer than the list box is wide, is there a way to see all the information (horizontal scroll bar, hint, another window, etc)?
