Vertical slider input component

Slider

The vertical slider is an input component that allows writing a value by dragging the slider to a position.

Features​

Configuration​

This section controls the behavior of the slider:

Value - the default value of the slider.

note

Only numeric values are supported

Target variable - the input variable to which the value will be written.

Min value - the minimum allowed input value. Values below this threshold cannot be written.

Min variable - If specified, it will use a runtime variable to dynamically adjust the Min value.

Max value - the maximum allowed input value. Values above this threshold cannot be written.

Max variable - If specified, it will use a runtime variable to dynamically adjust the Max value

Precision - the number of decimal digits to show and allow in the input.

Step - the increment used when dragging the slider.

Style​

The style properties define the default look and feel of the component (i.e. no state is active or defined).

Background color - the background color of the component. A hex value can be input in one the formats:

  • #RRGGBB
  • #RRGGBBAA
  • #RGB
  • #RGBA

Where:

  • R=red color component
  • G=green color component
  • B=blue color component
  • A=alpha (transparency) component

Alternatively, the integrated color picker can be used to visually pick a color:

Progress color - the color used to show the slider value.

Label color - the color used for the component label text.

Marks color - the color used for the slider marks.

Shadow - allows specifying a component shadow using the built-in shadow editor:

Shadow editor

  • X offset - the shadow vertical offset in pixels (can be negative)
  • Y offset - the shadow vertical offset in pixels (can be negative)
  • Blur - the shadow blur radius. A higher value results in a blurrier shadow, while a lower value will result in a more sharp shadow.
  • Color picker - the shadow color

Opacity - controls the transparency of the component.

States​

This section allows defining condition-based visual states. These can be used to alter the look based on external factors.

States variable - the runtime variable which is used to evaluate the state. The value of this variable is compared against the value of each state to decide which is the active state. If no match is found, the component will be displayed using its default values.

Test value - this is a test value that can be used to change the active state at design time. It simulates receiving the test value as the state variable value.

States - the list of defined states. Use the green button to add a new state:

Add state

State properties​

Trigger - Chooses the trigger value for the state. If set to Value, the HMI will compare the value received through the States variable against the provided numeric value. If set to Variable, it will evaluate the variable value and compare it against the States variable value. If the two values are equal, the compoent will switch to this state.

Background color - the background color of the component. A hex value can be input in one the formats:

  • #RRGGBB
  • #RRGGBBAA
  • #RGB
  • #RGBA

Where:

  • R=red color component
  • G=green color component
  • B=blue color component
  • A=alpha (transparency) component

Alternatively, the integrated color picker can be used to visually pick a color:

Color picker

Progress color - the color used to show the slider value.

Label color - the color used for the component label text.

Marks color - the color used for the slider marks.

Opacity - controls the transparency of the component.

note

The opacity and background alpha component both affect the transparency of the component, but have different behaviors. The opacity affects the whole component, while the background alpha affects only the background transparency.

Behavior - allows special behavior in the specified state:

  • none - no special behavior (component is rendered normally)
  • blink - the component will blink periodically
  • disabled - the component is rendered as disabled and will not respond to mouse or keyboard interaction
  • hide - the component is completely hidden
note

The hide behavior is different than using an opacity of 0. A hidden component will not receive any mouse or keyboard interaction, instead any component below it will receive them. On the contrary, a component with 0 opacity (fully transparent) still exists on the layout and will receive mouse or keyboard interactions.

Typography​

The typography section contains properties that affect the text-related properties of the component:

Label - if set, it will display a static label text.

Icon - if set, it will display an icon on the left of the label text.

Unit - if set, it will display the unit of measure.

Font size - the size of the font used for the input text.

Label font size - the size of the label text.

Marks font size - the size of the text used to show the mark values.

Label position- the vertical alignment of the label text with regard to the component width. This property affects the label, so it requires a label text to be set.

Layout​

Slider size - the height of the slider

Show value - if checked, it will display the value as a text label

Show marks - if checked, it will show the slider marks

Marks count - the number of subdivisions for which marks will be shown.

Border radius: Border radius for the border corners. Values can be manually input as:

  • <top-left>px <top-right>px <bottom-left>px <bottom-right>px
  • <left>px <right>px
  • <all>px

Alternatively, the built-in border radius editor can be used for a visual input:

Border radius

Position​

The position section contains properties which affect the position and size of the component. These can be changed by dragging and resizing the component with the mouse, or directly, by manually entering the values:

Left - distance from the left edge in pixels

Top - distance from the top edge in pixels

Width - component width in pixels

Height - component height in pixels
