All Implemented Interfaces:

GConstants, processing.core.PConstants

public class GCustomSlider
extends GLinearTrackControl

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.
