SLIDER

The SLIDER control represents a slider. The main use of the slider is to limit the user input to specific values. It uses a number representation for its values, but the numbers can also be used to express string values.

The following topics are covered below:


Example

Slider

The XML layout definition is:

<rowarea name="Number Output">
    <itr>
        <slider valueprop="slider1" from="13" to="60" showrange="true"
                                              showcurrentvalue="false">
        </slider>
    </itr>
</rowarea>

The control can be customized by setting its start value, end value and a step. The start and end values form a closed interval. The step defines the distance between two valid values represented by the slider in this interval.

Slider

In the above example, the value for the step is the default value "1". The possible values represented by the slider are the integers from "13" to "60". It is possible to specify a floating-point number as a step, for example "0,25". The slider can be further customized by setting the properties showrange and showcurrentvalue which show the range (start and end value) and the current value of the slider while the user is moving it. The width and height of the slider point is adjustable. The slider point is the element which the user drags and drops. The colors, the borders of the slider, the point, the line, the range and the current value can also be customized.

The Java code of the adapter is:

package com.softwareag.cis.test22;
// This class is a generated one.

import com.softwareag.cis.server.*;
import com.softwareag.cis.server.util.*;

public class SliderAdapter
    extends Adapter
{

    public class NumberSLIDERInfo extends SLIDERInfo
    {
        public void trigger()
        {
            m_fieldNumber = this.giveFormattedSliderValueAsInt();
        }
    }

    public class StringSLIDERInfo extends SLIDERInfo
    {
        public void trigger()
        {
        	int inpValue = this.giveFormattedSliderValueAsInt();
        	if(inpValue == 1) m_fieldString = "very bad";
        	else if(inpValue == 2) m_fieldString = "bad";
        	else if(inpValue == 3) m_fieldString = "ok";
        	else if(inpValue == 4) m_fieldString = "good";
        	else if(inpValue == 5) m_fieldString = "very good";
        }
    }

    // property >fieldNumber<
    int m_fieldNumber;
    public int getFieldNumber() { return m_fieldNumber; }
    public void setFieldNumber(int value)
    {
        m_fieldNumber = value;
    }

    // property >slider1<
    NumberSLIDERInfo m_slider1=new NumberSLIDERInfo();
    public NumberSLIDERInfo getSlider1() { return m_slider1; }
    public void setSlider1(NumberSLIDERInfo value) { m_slider1 = value; }

    // property >fieldString<
    String m_fieldString;
    public String getFieldString() { return m_fieldString; }
    public void setFieldString(String value) { m_fieldString = value; }

    // property >slider2<
    StringSLIDERInfo m_slider2=new StringSLIDERInfo();
    public StringSLIDERInfo getSlider2() { return m_slider2; }
    public void setSlider2(StringSLIDERInfo value) { m_slider2 = value; }

    // property >slider3<
    SLIDERInfo m_slider3=new SLIDERInfo();
    public SLIDERInfo getSlider3() { return m_slider3; }
    public void setSlider3(SLIDERInfo value) { m_slider3 = value; }

    /** initialisation - called when creating this instance*/
    public void init()
    {
        m_slider1.setSliderValue(18);
        m_slider2.setSliderValue(3);
    }

    /** */
    public void onEnterNumber()
    {
        m_slider1.setSliderValue(m_fieldNumber);
        m_fieldNumber = m_slider1.giveFormattedSliderValueAsInt();
    }

}

Every slider is bound to a SLIDERInfo object. Calling the setSliderValue() method sets the value of the slider which automatically moves it. However, the slider is not set to every given value, but to one valid value which fits in the given interval. The valid value to which the slider is currently set can be obtained by calling the giveFormattedSliderValueAsInt() or giveFormattedSliderValueAsFloat() method. When the user drops the slider, the method trigger() is called. This can be used to define specific behavior when the value in the user interface is changed. As in the example above, the SLIDERInfo can be extended, and the trigger() method can be overwritten to define specific behavior. You can show the new value in another control or use it for other purposes.
