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:

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.

Buttons may be set (i.e. depressed) by D3PLOT itself, for example the Solids & Shells one above, to indicate that this option is in force. They may also be greyed out, for example the Cont Surfs 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:

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.

TEXT BOXES:

To enter text in a text box: first make it "live" by clicking on it, then type in text, then type <return> to enter the string. Clicking on a "live" box for a second time is exactly the same as typing <return> , so clicking twice on a box effectively enters its current contents. You can use the left and right arrow keys for line editing within a box: text entry takes place after the current cursor position.

RADIO BOXES:

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.

POPUP MENUS:

Where a button has a "right arrow" > symbol it means that a popup menu is available.

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.
