Name Gallery - Extend dialog box
To display this dialog box select Stretches in the drop-down list on the Name Gallery. Then click the arrow to the right of the Name you want to change the stretching options. (An example of where to use stretching is a button with text on it. You can make the button stretch as you add characters to the text. In this example, you would set stretching options for the button.) Both the object that stretches (the button) and the object that controls the stretching (the text) must be named objects.
From the list of Named objects select which names should control the stretching. (In the above example you would select the Name for the text.)
Next select what stretching actions you want. Options are None, Extend (stretch from the center of the object) and Stretch (stretch the complete object - has the same effect as stretching the object using the Selector Tool). An example of the difference between Extend and Stretch is a rectangle with rounded ends. Extend stretches the center of the rectangle; the corner radius is unchanged. Stretch elongates the entire rectangle and the round corners become elliptical.
