Detailed Description

Base class for linear sliders.

This class provides the ability to control the orientation the text should be displayed. It also enables the use of labels for each tick mark.

Member Function Documentation

◆ calcTrackOffset()

float g4p_controls.GLinearTrackControl.calcTrackOffset ( )

protected

Calculates the amount of offset for the labels

Reimplemented in g4p_controls.GCustomSlider.

◆ draw()

void g4p_controls.GLinearTrackControl.draw ( )

Reimplemented from g4p_controls.GAbstractControl.

◆ getTrackOffset()

float g4p_controls.GLinearTrackControl.getTrackOffset ( )

Returns: the visual offset for the value/label text.

◆ getValueS()

String g4p_controls.GLinearTrackControl.getValueS ( )

If we are using labels then this will get the label text associated with the current value.
If labels have not been set then return null

Returns: get current value as a String

Reimplemented from g4p_controls.GValueControl.

◆ mouseEvent()

void g4p_controls.GLinearTrackControl.mouseEvent ( MouseEvent event )

Reimplemented from g4p_controls.GAbstractControl.

◆ setShowTicks()

void g4p_controls.GLinearTrackControl.setShowTicks ( boolean showTicks )

Set whether the tick marks are to be displayed or not. Then recalculate the track offset for the value and limit text.

Parameters

showTicks the showTicks to set

Reimplemented from g4p_controls.GValueControl.

◆ setTextOrientation()

void g4p_controls.GLinearTrackControl.setTextOrientation ( int orient )

Set the text orientation for the display of the limits and value if appropriate.
Acceptable values are G4P.ORIENT_LEFT, G4P.ORIENT_RIGHT or G4P.ORIENT_TRACK
If an invalid value is passed the ORIENT_TRACK is used.

Parameters

orient the orientation of the number labels

◆ setTickLabels()

void g4p_controls.GLinearTrackControl.setTickLabels ( String[] tickLabels )

This method is used to set the text to appear alongside the tick marks.
The array passed must have a minimum of 2 elements and each label (element) must have at least 1 character. If these two conditions are not met then the call to this method will be ignored and no changes are made.

Parameters

tickLabels an array of strings for the labels

◆ setTrackOffset()

void g4p_controls.GLinearTrackControl.setTrackOffset ( float offset )

The offset is the distance the value/labels are drawn from the centre of the track.
You may wish to tweak this value for visual effect.

Parameters

offset the offset value in pixels
