An example of a pointer displayer displayed in process the D2000 HI process:

To create the pointer displayer

...

Each pointer displayer can display the values of as many as 12 objects. So the tab Objects contains input edit boxes to define 12 objects. To define the objects either entering enter their names or select them from a list opened after clicking the button placed right from the input box.

...

If you define more than one object for the displayer, the displayer will consist of several subdisplayers. Number The number of the subdisplayers depends on the number of defined connected objects. However, the subdisplayers are not individual graphic objects and therefore all configuration parameters are common for all the subdisplayers. Then the pointer displayer, in dependence on its height and width, is sectioned either vertically or horizontally.

Color for displaying a given object is defined by clicking the button placed left from the input box.

For an object of Structured variable type, you must define the column name (the parameter Column) and row number (the parameter Row). For an object of Value arraytype, you must define a an item (the button L), whose value will be displayed.

...

The parameters placed on the tab are identical with to the parameters on the tab Control of the Connect object palette.

...

Specifies the name of the displayer in the form of a reference variable for use in the picture script.

...

Assignment of application data (metadata) to a graphic object. If the object contains some metadata, the name of the first record will be displayed in on the button. Multiple records are indicated by ",...".

Event

The listbox allows the user to select an active picture event for the displayer. The listbox contains the following active picture events:

...

Text to display as a tooltip when the user points the mouse cursor to the displayer in the picture opened in process the D2000 HI process.

Parameters

...

Descr.

Input the edit box to enter a description of the pointer displayer. In this box, it is possible to use so-called format masks, which allow to display displaying individual attributes of the complex value values of the D2000 system object. In this way, an a description can display e.g. current value of the connected object. For more information see the topic Format masks.
Possibility to use the Dictionary (to open press CTRL+L).

...

Note: By using a format mask in a description of the pointer displayer containing of several connected objects, there will be displayed an attribute for each connected object - the parameters Object nr. 1 up to Object nr. 12.

...

Clicking on the color sample opens the color palette. Selected The selected color will be used for a defined description of the pointer displayer.

...

The parameters Major and Minor defines a define the number of ticks of the pointer displayer scale. The parameter Label on every defines a density of labelinglabelling. Number The number of decimal places for can be defined in the parameter Decimals.
