Chapter 9 Creating VIs

The icon of a VI represents it as a subVI in the block diagram of other VIs.

It can be a pictorial representation of the purpose of the VI, or a textual

description of the VI.

1. Open Temp & Vol.vi in the BridgeVIEW\Activity directory.

2. From the front panel, pop up on the icon in the top right corner and

select Edit Icon…. You also can double click on the icon to invoke the

icon editor.

Note You only can access the icon/connector for a VI from the front panel.

3. Erase the default icon. With the Select tool, which appears as a dotted

rectangle, click and drag over the section you want to delete, and press

the <Delete> key. Y ou also can double click on the shaded rectangle in

the tool box to erase the icon.

4. Draw a thermometer with the Pencil tool.

5. Create the text with the Text tool. To change the font, double-click on

the Text tool. Your icon should look similar to the following

illustration.

6. Close the Icon Editor by clicking on OK. The new icon appears in the

icon pane.

7. Define the connector terminal pattern by popping up in the icon pane

on the front panel and choosing Show Connector. By default,

BridgeVIEW selects a terminal pattern based on the number of

controls and indicators on the front panel. Because there are two

objects on the front panel, the connector has two terminals, as shown

at left.
