Method Summary | |
---|---|
float |
getMaximum()
Obtains the maximum value permitted. |
String |
getMaxLabel()
Obtains the label for the maximum value, such as "Right" or "Full." |
String |
getMidLabel()
Obtains the label for the mid-point value, such as "Center" or "Default." |
float |
getMinimum()
Obtains the minimum value permitted. |
String |
getMinLabel()
Obtains the label for the minimum value, such as "Left" or "Off." |
float |
getPrecision()
Obtains the resolution or granularity of the control, in the units that the control measures. |
String |
getUnits()
Obtains the label for the units in which the control's values are expressed, such as "dB" or "frames per second." |
int |
getUpdatePeriod()
Obtains the smallest time interval, in microseconds, over which the control's value can change during a shift. |
float |
getValue()
Obtains this control's current value. |
void |
setValue(float newValue)
Sets the current value for the control. |
void |
shift(float from,
float to,
int microseconds)
Changes the control value from the initial value to the final value linearly over the specified time period, specified in microseconds. |
String |
toString()
Provides a string representation of the control |
