Mouse and Keyboard Usage for Screen Menu Interface
Mouse and keyboard usage for screen-menu interface
| All screen-menu operations are driven with the left mouse button, with the following exceptions: |
| Text in the dialogue area and text boxes requires keyboard entry; |
| Text strings saved in the cursor "cut" buffer may be "pasted" into dialogue areas and text boxes using the middle mouse button. |
| Popup" menus are invoked using the right mouse button. |
The primitive "widgets" in the menu interface are used as follows:
BUTTONS:
Buttons may be set (i.e. depressed) by D3PLOT itself, for example the one above, to indicate that this option is in force. They may also be greyed out, for example the one above, to indicate that the option is not currently available. Some buttons repeat automatically when held depressed: this depends on context. Buttons with " " after them will invoke sub-menus. |
SLIDERS:
|
TEXT BOXES:
|
RADIO BOXES:
|
MENU LISTS:
|
POPUP MENUS:
Click the right mouse button and the menu will appear. Holding down the right mouse button drag it onto the item you want. Popup menus can be nested to any depth. Note that popup menus can be invoked both from "clickable" buttons and from "non-clickable" ones: it makes no difference to their functionality. |

Screen buttons are depressed by clicking on them, but action only takes
place when the mouse button is released, so it is safe to drag the (depressed)
mouse around the screen.
Sliders are moved by clicking on the slider button itself, and then dragging
it to a new position. They may also be moved automatically by clicking
on, and holding down, one of the arrows at either end.
To enter text in a text box: first make it "live" by clicking on it,
then type in text, then type
A "radio" set is provided where only one selection is possible from a
range of options. In this example the laser postscript output has been
set to a single image per page. To select click anywhere on the row of
the relevant option, any previously selected item will be deselected.
Menus of items are used when you need to make one or more selections
from a (potentially) long list. Click on the row you want to select: clicking
on a row that is already selected will have the effect of unselecting
it. When the list is too long to display in the window you can use the
vertical scroll-bars to move up and down it.
