Visualization Element ‘Line’

Symbol:

Label: Basic

The element draws a single line.

Element properties

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

Element property ‘Position’

The following properties define the position and length 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.

Dots

[0]: Coordinates of the starting point [1]: Coordinate of the end point You can also change the values by dragging the box symbols ( ) to other positions in the editor.

Angle

Static angle of rotation (in degrees). Example: 35 The element is displayed rotated in the editor. The point of rotation is the center of the element. A positive value rotates clockwise. Tip: You can change the value in the editor by focusing the element to the handle. When the cursor is displayed as a rotating arrow , you can rotate the element about its center as a handle. Example: (1): Handle Note: If a dynamic angle of rotation is also configured in the property Absolute movement ‣ Internal rotation, then the static and dynamic angles of rotation are added in runtime mode. The static angle of rotation acts as an offset.

Element property ‘Text properties’

The properties contain fixed values for the text properties.

Horizontal alignment	Horizontal alignment of the text within the element.
Vertical alignment	Vertical alignment of the text within the element.
Text format	Definition for displaying texts that are too long Default: The long text is truncated. Line break: The text is split into parts. Ellipsis: The visible text ends with “…” indicating that it is not complete.
Font	Example: Default : The Font dialog box opens. : Drop-down list with style fonts.
Font color	Example: Black : The Color dialog box opens. : Drop-down list with style colors.
Transparency	Whole number (value range from 0 to 255). This determines the transparency of the respective color. Example: 255: The color is opaque. 0: The color is completely transparent. Please note: If the color is a style color and already has a transparency value, then this property is write-protected.

Element property ‘Absolute movement’

The properties contain IEC variables for controlling the position of the element dynamically. The reference point is the upper left corner of the element. In runtime mode, the entire element is moved.

Movement
X	Variable (numeric data type). Defines the X position (in pixels). Example: PLC_PRG.iPos_X. Increasing this value in runtime mode moves the element to the right.
Y	Variable (numeric data type). Defines the Y position (in pixels). Example: PLC_PRG.iPos_Y. Increasing this value in runtime mode moves the element downwards.
Rotation	Variable (numeric data type). Defines the angle of rotation (in pixels). Example: PLC_PRG.iAngle1. The midpoint of the element rotates at the Center point. This rotation point is shown as the symbol. in runtime mode, the alignment of the element remains the same with respect to the coordinate system of the visualization. Increasing the value rotates the element to the right.
Scaling	Variable (integer data type). Causes centric stretching. Example: PLC_PRG.iScaling. The reference point is the Center property. The value 1 shrinks the element by a factor of 0.001. The value 1000 returns the element to its original size.
Internal rotation	Variable (numeric data type). Defines the angle of rotation (in pixels). Example: PLC_PRG.iAngle2. In runtime mode, the element rotates about the point of rotation specified in Center according to the value of the variable. In addition, the alignment of the element rotates according to the coordinate system of the visualization. Increasing the value in the code rotates clockwise. The rotation point is shown as the symbol. Note: If a static angle of rotation is specified in the property Position ‣ Angle, then the static angle of rotation is added to the variable angle of rotation (offset) when the visualization is executed.
Use REAL values	Note: Only available if the device supports the use of REAL coordinates. : The properties of the absolute movement are interpreted as REAL values. The values are not rounded. The option allows for the individual fine-tuning of drawing the element, for example for the visualization of a smoother rotation. Tip: If a horizontal or vertical line is drawn blurry on a specific visualization platform, then this can be corrected by an offset of 0.5px in the direction of the line thickness.

Note

You can link the variables to a unit conversion.

Element property ‘Relative movement’

The properties contains variables for moving the element. The reference point is the position of the element (Position property). The shape of the element can change.

Movement point[0] X Y	Variable (numeric data type). It contains the number (in pixels) that the starting point of the line is moved. Incrementing the X value moves the element to the right. Incrementing the Y value moves the element to the down.
Movement point[1] X Y	Variable (numeric data type). It contains the number (in pixels) that the end point of the line is moved. Incrementing the X value moves the element to the right. Incrementing the Y value moves the element to the down.

Element property ‘Text variables’

These properties are variables with contents that replace a format definition.

Text variable

Variable (data type compliant with the format definition). It contains what is printed instead of the format definition. Example: PLC_PRG.iAccesses Note: The format definition is part of the text in the property Texts ‣ Text. Note: If you specify a variable of type enumeration with text list support, then the name of the enumeration data type is added automatically in angle brackets after the variable name. Example: PLC_PRG.enVar <myEnum>. Then the symbolic value of the enumeration component is printed instead of the numeric value when text is printed. Refer to the help page for the DUT object.

Tooltip variable

Variable (data type compliant with the format definition). It contains what is printed instead of the format definition. Example: PLC_PRG.iAccessesInTooltip Note: The format definition is part of the text in the property Texts ‣ Tooltip.

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.

Element property ‘Line width variable’

Dynamic definition of the weight of a line element using a variable.

Integer value

Variable (integer data type). Defines the line weight of the element (in pixels). This overwrites the fixed value that is defined in Appearance ‣ Line weight. Note: The value 0 codes the same as 1 and sets the line weight to one pixel.

Element property ‘Line style variable’

Integer value

Variable (integer data type). Defines the appearance of the line at runtime. 1: Solid 2: Dashes 3: Dots 4: Dash Dot 5: Dash Dot Dot 6: Invisible: The line is not drawn.

Element property ‘Input configuration’

The properties contain the configurations for the user input when using the mouse or keyboard. A user input defines an event and one or more actions that are executed when an event occurs.

The Configure button opens the Input configuration dialog box for creating or modifying a user input. Configured user inputs are briefly listed below the events. They each include the action that is triggered and the setting in short form. Example: Execute ST code: PLC_PRG.i_x := 0;
OnDialogClosed	Input event: The user closes the dialog box.
OnMouseClick	Input event: The user clicks the mouse button completely. The mouse button is clicked and released.
OnMouseDown	Input event: The user clicks down on the mouse button.
OnMouseEnter	Input event: The user drags the mouse pointer to the element.
OnMouseLeave	Input event: The user drags the mouse pointer away from the element.
OnMouseMove	Input event: The user moves the mouse pointer over the element area.
OnMouseUp	Input event: The user releases the mouse button over the element area.

Tap	When a mouse click event occurs, the variable defined in Variable is described in the application. The coding depends on the options Tap FALSE and Tap on enter if captured.
Variable	Variable (BOOL) that is set on mouse click. Example: PLC_PRG.bIsTapped TRUE: A mouse click event exists. It lasts while the user presses the mouse button over the element. It ends when the button is released. FALSE: A mouse click event does not exist. Requirement: The Tap FALSE option is not activated.
Tap FALSE	: The mouse click event leads to a complementary value in Variable. TRUE: A mouse click event does not exist. FALSE: While the mouse click event exists.
Tap on enter if captured	: During user input, it is also taken into consideration whether the mouse pointer is dragged within the element area or not while the mouse button is pressed. TRUE: While the mouse click event exists and the mouse pointer is moved over the element area. FALSE: A mouse click event does not exist. Or the user moves the mouse pointer outside of the element area while the mouse button is pressed. The value is TRUE again as soon as the user moves the pointer back to the element area. The mouse is then captured.

Shift	With the onset of a mouse click event, the variable is set; when the mouse click event is completed, the variable is reset.
Variable	Variable (BOOL). Its value toggled when the mouse click event is ended. This is when the user releases the mouse button while the mouse pointer is over the element area. If the user releases the mouse button while the mouse pointer is outside of the element area, then the mouse click event is not ended and the value is not toggled. Tip: The user can cancel a started toggle input by dragging the mouse pointer out of the element area.
Toggle on up if captured	: The value toggles regardless of where the mouse pointer is when the mouse button is released. The mouse is then captured.

Keyboard shortcuts	Keyboard shortcut on the element for triggering specific input actions. When the keyboard shortcut event occurs, the input actions in the Event(s) property are triggered. In this way, it is not the input action itself that leads to this input action, but the mouse input action.
Key	Key pressed for input action. Example: T Note: The following properties appear when a key is selected.
Event(s)	None Mouse down: Pressing the key triggers the input actions that are configured in the OnMouseDown property. Mouse up: Releasing the key triggers the input actions that are configured in the OnMouseUp property. Mouse down/up: Pressing and releasing the key triggers the input actions that are configured in the OnMouseDown property and the OnMouseUp property.
Shift	: Combination with the Shift key Example: Shift+T.
Control	: Combination with the Ctrl key Example: Ctrl+T.
Alt	: Combination with the Alt key Example: Alt+T.

Note

All keyboard shortcuts and their actions that are configured in the visualization are listed in the Keyboard configuration tab.
