2.16.2.1.8 Arrow element

The arrow display element draws a horizontal or a vertical line and optionally an arrowhead. The line's color is selectable. Strictly speaking the Line / Arrow element is a rectangle with only one or two sides drawn.

The attributes listed below may be configured to customize a display element of this type:

• Message ID: The message ID addresses the parameter the element shall display or edit. The message ID consists of the MNC name, device name followed by a colon and the name of the parameter.ANT.11.XMIT-1.tx.on for example addresses the variable tx.on at a device named XMIT-1 at MNC.
• Color: The color to be used to draw the line unless a use variable line color is specified. Colors may be specified by using a hexadecimal RGB notation. You may click to the color example field in order to open a color chooser dialog and select the color from there.
• Arrows and lines: You can choose the arrow or line from options. Simply click the option.
• Use variable line color: Check this checkbox to let draw the line with a color specified by the value of the variable specified by 'message ID'. Unless you check the mark 'use color translation table'.
• Use color translation table: Checking this checkbox enables a color translation table which works much like the variable background color feature for entry elements. Depending on the actual value of the variable addressed by 'message ID', the element's line color and thickness is set using the translation table shown in the lower left corner of the dialog. If the actual value of the variable does not match any of the table entries or if no message ID is specified, the first color in the list is used to draw the element's background.
  • Value: The parameter value of the actually selected table entry.
  • Color: The color specification of the actually selected table entry. Clicking to this opens a color chooser dialog which lets you select/compose the the color to your needs.
  • Bold: Specifies the line width of the currently selected table entry. If the checkmark is checked, the line is drawn 3 pixels wide, if the checkbox is not checked, the line width is 1 pixel.
  • Add: To add a new value / color pair to the list, fill the value and color fields.
  • Set: To change the color assigned to a given parameter value, first select the table entry of interest, change the color value.
  • Delete: To delete a value / color pair from the list, first select the table entry then click delete.
