Basic Controls

Standard Basic Controls

Most controls have very few properties to modify, apart from the standard position, rotation and opacity options. The extra options are listed below.

Property	Result
Style: Defines the appearance of a button, knob, switch or slider. Set the value to 0 or 1 to choose the object style.
State: Defines the state of a button (on or off). Set the value to 0 or 1 to choose the object state.
Start/End/Value: Defines the start and end values for the knob, rotary switch, or slider. In this example, the rotary switch values run from 0 to 5 in steps of 5, and the current value is set to 2.

Numeric Input

Figure 33: Numeric input primitive

The Numeric Input allows you to enter a numeric value through your keyboard's numeric keypad during a simulation. As well as the standard properties, you can configure the keypad as follows:

• repeat delay: this value defines the time delay between increments when the arrow keys are clicked and held. If the value is set to 1, the delay between clicks being taken into account is short. If the value is set to 1000, the delay between clicks being taken into account will be long (the user will have to wait longer before his clicks are taken into account).

• repeat period: this value defines the speed of decrease or increase of the increments when the arrow keys are clicked and held. If the value is set to 1, the increments will occur rapidly. If the value is set to 1000, the increments will occur slowly.

• number of integer digits: define the number of digits to display before the decimal point

• number of fractional digits: define the number of digits to display after the decimal point

• default value: define the value to be set when the reset button is clicked

• increment: define the increments for the arrow buttons. This value must be set in conjunction with the number of integer digits and number of fractional digits settings. It is pointless to set an increment of 0.5 if your number of fractional digits value is set to 0.
