Setting Component Properties — The Property Inspector

3-47

The SliderStep property controls the amount the slider Value property

changes when you click the mouse on the arrow button or on the slider trough.

Specify

SliderStep as a two-element vector. The default, [0.01 0.10], provides

a 1 percent change for clicks on an arrow and a 10 percent change for clicks in

the trough. The actual step size is a function of the slider step and the slider

range.

Designing a Slider. Suppose you want to create a slider with the following

behavior:

• Slider range = 5 to 8

• Arrow step size = 0.4

• Trough step size = 1

• Initial value = 6.5

Set the following slider properties using the Property Inspector.

X denotes the

first element of the

SliderStep vector. Y denotes the second element.

•

SliderStep, X .133

• SliderStep, Y .333

• Max 8

• Min 5

• Value 6.5

SliderStep

is a percentage of the slider range, which is 3. In this example,

SliderStep for the arrow step size is 0.4/3 = 0.1333. SliderStep for the

trough step size is

1/3 = 0.3333.

Setting Pop-Up Menu Properties

Pop-up menus open to display a list of choices when users click the arrow.

Adding Items to the Pop-Up Menu. The String property contains the list of strings

displayed in the pop-up menu. Use the Property Inspector to add items to the

pop-up menu by typing one per line in the

String edit box:

1 2 ... 92 93 94 95 96 97 98 99 100 101 102 ... 215 216
