Detailed Description

This slider is used to control 2 variables by dragging the thumb over a 2D surface. It has all the features of the standard slider (GSlider) except that it does not have ticks or stick-to-ticks functionality.

If no limits are set then the control will return a value in the range 0.0 to 1.0 for both the x and the y axis. The setXlimits and setYlimits can be used to set a different range for each axis independently.

The minimum size for this control is 40x40 pixels and this is enforced when the control is created. If necessary the width and/or height the rectangle will be increased to 40pixels.

Returns: the current X value as an integer.
DECIMAL and EXPONENT value types will be rounded to the nearest integer.

◆ getValueXS()

String g4p_controls.GSlider2D.getValueXS ( )

Returns: the current X value as a string taking into account the number format.

◆ getValueYF()

float g4p_controls.GSlider2D.getValueYF ( )

Returns: the current Y value as a float

◆ getValueYI()

int g4p_controls.GSlider2D.getValueYI ( )

◆ setEasing()

void g4p_controls.GSlider2D.setEasing ( float easeBy )

Set the amount of easing to be used when a value is changing. The default value is 1 (no easing) values < 1 will cause the value to rush from its starting value and decelerate towards its final values. In other words it smoothes the movement of the slider thumb or knob rotation.

Parameters

easeBy the easing to set

◆ setLimitsX() [1/3]

void g4p_controls.GSlider2D.setLimitsX	(	float	initValue,
		float	start,

X (horz) limits Sets the initial value and the range of values to be returned. This method will assume that you want to set the valueType to DECIMAL.

Parameters

initValue	the initial value
start	the X start value of the range
end	the X end value of the range

◆ setLimitsX() [2/3]

void g4p_controls.GSlider2D.setLimitsX	(	float	start,
