- █ Dialog boxes
-
- The dialog box is a special window
- designed for the program to get information
- from the user. It is a convenient way to
- view and set multiple options.
-
- When you are making settings in a
- dialog box, you work with the following
- basic GraphVision dialog controls: input-
- line boxes, command buttons, list boxes,
- check boxes and radio buttons.
-
- If you are using a mouse, click the
- button, field or box you want. When you
- are using the keyboard, press <Alt> and
- the underlined letter of an item to
- activate it. Press <Tab> to move among
- Input-line and List boxes.
-
-
- █ Input-line box
-
- You type input text into an Input-line
- box. Most basic text-editing keys work in
- the Input-line box. If you continue to
- type once you reach the end of the box, the
- contents automatically scroll. When you
- move to an empty Input-line box, an edit
- cursor (flashing underscore "_") appears .
- The text you type starts at this cursor
- point. If the box you move to already
- contains text, this text is selected, and
- any text you type replaces it.
-
-
- █ Command button
-
- Choose a Command button to initiate an
- action immediately, such as carrying out or
- canceling a command.
-
-
- █ List box
-
- A list box displays a list of choices.
- It contains a vertical scroll bar that lets
- you scroll through and select from
- variable-length lists (often names) without
- leaving a dialog box. You can use a mouse
- to make a selection, or use the arrow keys
- to move between list items and press
- <Space Bar> to select an item.
-
- █ Check box
-
- Check boxes are used to get multiple
- choices from user. You can select as many
- check box options as needed. When a check
- box is selected, it contains an X. To
- select a check box, click the box or select
- the group you want and use the arrow keys
- to choose a particular check box, then press
- <Space Bar> to select it.
-
- █ Radio buttons
-
- Radio buttons represent mutually
- exclusive choices. For this reason, radio
- buttons always come in groups, and you can
- select only one option at a time. The
- selected radio button contains a black dot.
- To select a radio button, click the button
- or select the group you want and use the
- arrow keys to choose a particular radio
- button.
