Visualization Element ‘Slider’

Symbol:

Tag: Common controls

This element adjusts the value of a variable, depending on the position of the slider within the slider bar. You define the value range of the slider bar by means of the scale start and scale end.

Element properties

Element name	Optional Tip: Assign individual names for elements so that they are found faster in the element list. Example: Speed_Conveyor_1
Element type	Slider

Element property ‘Position’

The position defines the location and size of the element in the visualization window. These are based on the Cartesian coordinate system. The origin is located at the upper left corner of the window. The positive horizontal x-axis runs to the right. The positive vertical y-axis runs downwards.

X	X coordinate of the upper left corner of the element Specified in pixels. Example: 10.
Y	Y coordinate of the upper left corner of the element Specified in pixels. Example: 10.
Width	Specified in pixels. Example: 150
Height	Specified in pixels. Example: 30

Note

You can also change the values by dragging the box symbols ( ) to other positions in the editor.

Move to click	Function of the slider at visualization runtime when it is clicked: : The slider moves to the clicked position. : The slider moves to the value (defined in the Page size element property) in the direction of the click.

Element property ‘Scale’

Show scale	: The element has a visible scale. Note: This option is available for the slider only.
Scale start	Lowest value of the scale and the lower limit of the value range for the element (example : 0).
Scale end	Highest value of the scale and the upper limit of the value range for the element (example : 100).
Main scale	Distance between two tick marks of the rough scale (example: 10).
Subscale	Distance between two tick marks of the fine scale (example: 2). You can hide the fine scale by setting the value to 0.
Scale format (C Syntax)	Formatting of the scale label (example: %d %s) Note: This property is available for the slider only.
Scale proportion	Size of the scale (in %) of the total size

Element property ‘Bar’

The property defines the representation of scaling and direction of travel.

Diagram type	The drop-down list varies depending on the alignment of the diagram. Horizontal Top: Scale is above the slider. Bottom: Scale is below the slider. Top and bottom: Two scales frame the slider above and below. Vertical Left: Scale is left of the slider. Right: Scale is right of the slider. Left and right: Two scales frame the slider on the left and the right.
Orientation	Alignment of the slider; defined by the ratio of width to height. Horizontal Vertical You can modify the alignment in the visualization editor by using the pointing device to adjust the width and height of the scrollbar.
Running direction	The drop-down list varies depending on the alignment of the slider. Horizontal Left to right: Scale starts at the left. Right to left: Scale starts at the right. Vertical Bottom to top: Scale starts at the bottom. Top to bottom: Scale starts at the top.

Element property ‘State variables’

The variables control the element behavior dynamically.

Invisible	Variable (BOOL). Toggles the visibility of the element. TRUE: The element is not visible at runtime.
Deactivate inputs	Variable (BOOL). Toggles the operability of the element. TRUE: User inputs do not have any effect in runtime more. The element is shown as deactivated.
