2.16.2.1.3 Display element

The display element also known as read-only-parameter element is used to display M&C parameters as read-only. It looks much alike the parameter element, but never allows to change the parameter it displays.

• 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.

• Label: The label text is drawn above the element.

• Draw frameless with transparent background: Activate this option so that the element is drawn without an input field frame and with a transparent background. With this option, the read-only parameter element can be used as a label that changes its text with the value of a variable. Please note that you cannot use the color (Variable background color) option (described below) together with the frameless / transparent background option.

• Font: Font contains two options:

  • Font: The font attribute applies to the text shown in the parameter field itself. The label text is shown with the standard ("plain") font size for all font selections except the smallest one. In the latter case the label is drawn using this small font size, too.
  • color: The color attribute of a parameter element sets the color of the label shown above the entry field. The text in the parameter field itself always is shown in the default text color of the selected look & feel. 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.

• Conditionally enable widget: Parameter fields may be locked to read only state unless another parameter matches a given value. For instance, changing the position of a wave guide switch may be inhibited while the carrier is switched on. Check this to activate this feature.

  • Enable ID: This field defines the ID for the enabling parameter.
  • Enable value: The value belonging to the parameter above. The actual value of the parameter

• Color: Checking this mark enables the variable background color feature for this screen element. Depending on the actual value of the variable addressed by color id, the element's background is set using the translation table. If the actual value of the color id variable does not match any of the table entries or if no color id is specified, the first color in the list is used to draw the element's background.The buttons Add/Set/Delete along with the value and color fields are used to edit the color translation table.

  • Color ID: The message ID of the parameter which controls the background color of this element.
  • 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.
  • Value: The parameter value of the actually selected table entry.
  • Bold: Draws the text bold if the parameter value matches.
  • 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.
