ThresholdSlider Properties

Properties in View Designer

• readOnly

  Defines whether the colored bar can be moved with the mouse by the user. If readOnly=true, the slider can not be moved but the user can click on the slider. This triggers the Web Dynpro action onAction. If readOnly=false, then the user can use the mouse to change the position of the slider and also to change the value of the slider.

  Note

  OnChange does not make sense for readOnly=true since the user cannot use the slider.

  OnAction only works for readOnly=false, because otherwise it would not be clear whether the value should be changed or whether the intention was actually to click on the ThresholdSlider.

• state

  Value	Description
  normal	Initial Value Nothnig happens.
  required	The UI element ThresholdSlider is mandatory. This is displayed with an asterisk in front of the label (see graphic):

  The following method calls can be used to check the mandatory fields:

  • cl_wd_dynamic_tool=>check_mandatory_attributes()

  • cl_wd_dynamic_tool=>check_mandatory_attr_on_view()

  As soon as one of these method calls has been triggered, the system checks whether the referenced value is still initial or has been changed. If it has been changed, nothing happens. If it is still iniital, a message appears that consists of an icon and a link. When a link is selected, the focus is set on the referenced UI element. This is done using the context attribute.

• showTickMarks

  For showing/hiding TickMarks.

• tickMarkSpacing

  Gap between two TickMarks in units.

• maxTickMarks

  Total number of TickMarks.

• unitWidth

  Base unit in pixels.

• value

  Position of colored bar in units. This property must be bound against a context node.
