POPUP MENU
|
|
|
|
DESIGN CONSIDERATIONS
|
|
There is currently no support for nested popup menus. Let Kris know if
|
|
you need this.
|
|
|
|
USER INSTRUCTIONS
|
|
The goal of this popup menu system is to create a quick and intuitive
|
|
interface system which is functionally similar to Win95 and MacOS.
|
|
As soon as you click on a button which activates the popup menu, the user
|
|
will choose a selection in one of three ways:
|
|
|
|
1) KEYBOARD - at anytime, the user can use the keyboard regardless of mouse
|
|
mode. The up/down arrow keys will cycle through the choices and enter will
|
|
accept the choice. ESC will cancel the menu without making a choice.
|
|
2) When the mousedown event activates the menu, the user releases the mouse before
|
|
entering the popup menu region. The menu mode will change and become persistant.
|
|
Clicking on the hilighted item will close the popup and activate the choice.
|
|
Clicking elsewhere, the popup will be closed without making a selection. This
|
|
is functionally equivalent to Win95.
|
|
3) When the mousedown event activates the menu, the user holds the mouse down and
|
|
moves the cursor over the popup region. At this moment the menu becomes
|
|
non-persistant and a choice is made by releasing the mouse. If the mouse is
|
|
released on a highlighted choice, that choice is selected, otherwise the popup
|
|
is cancelled. This is functionally equivalent to MacOS. The small diffence is
|
|
that under Win95's standard convention, the release of the mouse outside of the
|
|
region doesn't kill the menu, but in MacOS, it does.
