from left, distance from bottom, height, width]. The values are given in the

units specified by the

Units property of the component.

1 Select the components you want to align. See “Selecting Components” on

page 6-31 for information.

2 Select Property Inspector from the View menu or by clicking the Property

Inspector icon .

3 In the Property Inspector, scroll to the Units property and note its current

setting, then change the setting to

inches.

4 Scroll to the Position property. A null value means that the element differs

in value for the different components. This figure shows the

Position

property for multiple components of the same size.

5 Change the value of x to align their left sides. Change the value of y to align

their bottom edges. For example, setting

x to 2.0 aligns the left sides of the

components 2 inches from the left side of the GUI.

6 When the components are aligned, change the Units property back to its

original setting.

Grid and Rulers

The layout area displays a grid and rulers to facilitate component layout. Grid

lines are spaced at 50-pixel intervals by default and you can select from a

number of other values ranging from 10 to 200 pixels. You can optionally

enable snap-to-grid, which causes any object that is moved or resized to within

9 pixels of a grid line to jump to that line. Snap-to-grid works with or without

a visible grid.
