These buttons determine in a similar manner the vertical position of a glue

point when the size of the object is changed.

Adding text to connectors

To add text to a connector, double-click the connector. The end and control points

become active and the familiar flashing text cursor appears (the cursor position is

determined by the most recent setting). The Text Formatting toolbar also appears

(under the menu bar). Use this toolbar to set the text properties; you can directly

insert the text.

If you draw a connector and then click on it, only the end points and control points

become visible. In spite of this, a connector has its own object frame—in this case an

invisible one. You can picture it easily by imagining a rectangle enclosing the start

and end points of the connector (Figure 211).

Figure 211: Object frame of a connector

When you add text to a connector, the location of the text is relative to this rectangle.

The exact position of the text can be set in the Text dialog (Figure 212). This dialog

appears when you double-click on text and then choose Text from the pop-up menu

or when you single-click on the connector and select Format > Text from the menu

bar.

Take particular note of the Spacing to borders and Text anchor sections in the Text

dialog. In the Text anchor section you can see the possible locations for the text. In

the example below the text is anchored at the top left. In the Spacing to borders

section at the lower left, negative values of spacing will position the text outside the

frame.
