Constructor & Destructor Documentation

◆ GSlider()

g4p_controls.GSlider.GSlider ( PApplet  theApplet,
float  p0,
float  p1,
float  p2,
float  p3,
float  tr_width 
)
Parameters
theAppletthe main sketch or GWindow control for this control
p0x position based on control mode
p1y position based on control mode
p2x position or width based on control mode
p3y position or height based on control mode
tr_widththe width of the track in pixels

Member Function Documentation

◆ setEnabled()

void g4p_controls.GSlider.setEnabled ( boolean  enable)

Enable or disable the ability of the component to generate mouse events.
GTextField - it also controls key press events
GPanel - controls whether the panel can be moved/collapsed/expanded

Parameters
enabletrue to enable else false

Reimplemented from g4p_controls.GAbstractControl.

◆ updateBuffer()

void g4p_controls.GSlider.updateBuffer ( )
protected

Reimplemented from g4p_controls.GAbstractControl.

◆ updateDueToValueChanging()

void g4p_controls.GSlider.updateDueToValueChanging ( )
protected

This should be overridden in child classes so they can perform any class specific actions when the value changes. Override this in GSlider to change the hotshot position.

Reimplemented from g4p_controls.GValueControl.
