A Slider allows your application users to interactively select a numeric value. When the user changes the position of the slider bar, an event is fired and the value property is changed.
3. In the lower panel of the left dock, scroll to the Maximum property and change the value to 1000.
4. Change the Value property to 500 set the default position of the slider.
To demonstrate the Slider functionality we will add a Value Display Widget within the same Container of your Mashup as the Slider and bind the slider widget output to the input of the Value Display.
1. In the Filter field where you entered slider, enter value.
2. Drag-and-drop a Value Display widget onto the same upper-right Container as the Slider widget.
3. Click the drop-down arrow on the left side of the Slider widget.
4. Click and drag the Value property listed in the Slider drop-down onto the Value Display widget.
5. Click the Data property that is available from the Select Binding Target pop-up.
6. Click Save to save your Mashup.
7. Click View Mashup then adjust the slider to see the changing value shown in the Value Display widget.
Many properties are available that give control over how a Slider widget will be displayed. Properties can be changed both statically when designing the Mashup, and dynamically in response to changes in property values.
