Detailed Description

Slider that can be customised with user provided graphics.

This class replaces the GWSlider provided in pre v3 editions of this library.

The main difference to the GSlider class is the ability to skin the slider with user provided graphics. The library provides a number of skins ready for use. You specify the skin to use when the slider is created and if the library is unable to load the skin it will print a warning and load the default skin instead.

Library skins available

  • grey_blue (default skin)
  • green_red20px
  • red_yellow18px
  • blue18px
  • purple18px

A skin requires 5 image files for different parts of the slider which must be stored in their own folder (the folder name is also used as the skin name) and this folder should be place inside the sketch's data folder.

The image files have specific names.

  • Left end cap of the slider(end_left.???)
  • Right end cap of the slider(end_right.???)
  • An extendible centre segment(centre.???)
  • Draggable thumb (handle.??? and handle_mouseover.???)

Where ??? is the image type file extension. The image type can be any that Processing can handle, the most common types will be png, jpg or gif but tga is also permitted

There are very few restrictions about the images you use but when designing the images you should consider the following facts:

  • the slider will be created to fit the control size (specified in the constructor)
  • the horizontal space allocated for the end-caps will be the same for each end (uses the width or the larger end cap image)
  • the track width will be the height of the centre image
  • the centre image will be tiled along the track length
  • the track will be placed in the horizontal and vertical centre of the control.
  • the end cap images will be placed in the vertical centre of the control and butted against the track.

)

Create a custom slider using the default skin.

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

◆ GCustomSlider() [2/2]

g4p_controls.GCustomSlider.GCustomSlider ( PApplet  theApplet,
float  p0,
float  p1,
float  p2,
float  p3,
String  skin 
)

Create a custom slider using the skin specified.

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
skinthe name of the skin (this is also the name of the folder holding the images)

Member Function Documentation

◆ calcTrackOffset()

float g4p_controls.GCustomSlider.calcTrackOffset ( )
protected

Calculates the amount of offset for the labels

Reimplemented from g4p_controls.GLinearTrackControl.

◆ setStyle()

void g4p_controls.GCustomSlider.setStyle ( String  skin)

Change the skin used for the slider.

Parameters
skinthe name of the folder holding the graphics for this slider

◆ updateBuffer()

void g4p_controls.GCustomSlider.updateBuffer ( )
protected

Reimplemented from g4p_controls.GAbstractControl.

◆ updateDueToValueChanging()

void g4p_controls.GCustomSlider.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.
