NAMEPush Button (Control) — Reference DescriptionA push button is a control that represents an action or dialog
choice. Figure 52 “Push Buttons” shows
three push buttons. When to Use- Required
If you do not provide a menu bar in a window with
a viewing area, place all action, cascading, or dialog choices on
push buttons in that window, except for those choices that appear
on the window menu. - Recommended
Use a push button in a window with a menu bar to
provide convenient access to a frequently used action choice, dialog
choice, or cascading choice.
GuidelinesBehavior- Recommended
For push buttons that provide action choices that
can be used repeatedly, such as the arrow buttons on the scroll
bar, do the following: Repeat the action if the user presses
and holds the SELECT button for an initial period of time (the initial
delay time specified by the operating environment). If the user
continues to press and hold SELECT, continue to repeat the action
whenever SELECT is held down for a period of time (the repeat delay
time specified by the operating environment). Represent a push button with ready emphasis while
it is active. Stop repeating the action when the user moves the
pointer away from the push button; resume repeating the action if
the user moves the pointer back over the push button without releasing
SELECT. If the user moves the pointer from one button of
an adjacent pair of arrow buttons that perform opposite actions
to the other button, switch the ready emphasis and switch actions.
- Recommended
When a push button is persistently unavailable (because
of the current configuration of the application or system or, for
example, a particular set of companion software is not currently
installed), remove the push button rather than showing it as unavailable. - Recommended
If a push button adjusts (or is associated with)
a control within a window (rather than the entire window), do not
close the window when a user activates the push button.
Layout- Recommended
When a window contains push buttons and a menu bar,
place choices in the pull-down menus that provide functions equivalent
to push-button functions. - Recommended
Allow a user to hide or remove push buttons if the
choices are available through another mechanism, such as the menu
bar. - Recommended
Combine existing menu choices to create new push-button
choices for frequently used combinations of choices. For example,
the Save and the New choices could be combined into a new push-button
choice called Save and New that would perform the Save action followed
by the New action. - Recommended
If the action indicated by the label on a push button
adjusts or is associated with a control within the same window as
the push button, place the push button near that control. For example,
if the function of a push button is to restore the initial value
in a text-entry field, place that push button beside the text-entry
field that it affects. - Recommended
Avoid using a push button to change the size of
a window; instead, allow the user to change the size of the window
with window menu choices and elements of the window frame.
Scrolling- Recommended
If the viewing area of a window can be scrolled
and the window contains push buttons that affect the entire window,
keep the push buttons visible when the viewing area is scrolled. - Recommended
If a window contains a push button that affects
a control in a viewing area, scroll the push button along with the
control when the user scrolls the viewing area.
