public class AgcJSlider

extends JSlider

implements ChangeListener, AgiHelpInfo

A lightweight component that lets the user graphically select a value by sliding a knob within a bounded interval. The slider can show major tick marks, minor tick marks, and tick labels.

AgcJSlider uses the model DefaultBoundedRangeModel, which holds the minimum, maximum, and current values. However, you don't have to interact directly with the model; methods inherited from the JSlider class let you set values in the model.

There are also inherited methods for specifying:

• Tick marks and labels
• Orientation of the slider (vertical or horizontal)
• Whether the minimum or maximum are inverted (maximum on the left instead of right, bottom instead of top)

This code changes the minimum value of the slider.

 	slider.setMinimum( -100 );
 

This code creates a new model, sets values, and assigns it to a slider control.

 	DefaultBoundedRangeModel m = 
 		new DefaultBoundedRangeModel();
 	
 	m.setMinimum( fldMin.getValue() );
 	m.setMaximum( fldMax.getValue() );
 	
 	slider.setModel( m );
 	
 

This code changes tick marks and labels.

 	// Calculate increment for 10 labels
 	int increment = ( slider.getMaximum() - slider.getMinimum() ) / 10 ;
 
 	// Display 10 tick marks and label the marks
 	slider.setMajorTickSpacing(increment);
 	Hashtable hshLabels = slider.createStandardLabels(increment);
 	slider.setLabelTable(hshLabels);
 

Properties:

Control Type, Data Column, Enabled, Height, Help Page, Initial Value, Inverted, Left, Major Tick Spacing, Maximum Value, Minimum Value, Minor Tick Spacing, Name, Orientation, Show Labels, Show Ticks, Snap to Ticks, Tool Tip, Top, Visible, Width

Events:

focusGained, focusLost, keyPressed, keyReleased, keyTyped, mouseClicked, mouseDragged, mouseEntered, mouseExited, mouseMoved, mousePressed, mouseReleased, validationFailed, validationTest, valueChanged
