6.4 Designing and implementing the visualization primitives

At this stage it is planned to implement the data models UI.VCAEngine and shapes of the Vision visualizer Vision, WebVision for all the basic elements: "ElFigure", "FormEl", "Text", "Media", "Diagram", "Protocol", "Document", "Function", "Box", "Link".

6.4.1 Elementary figure primitive (ElFigure)

The implementation on the data-model side (UI.VCAEngine) describes into the document's part 4.12.

UI.Vision


Support of the following elementary figures is provided: lines, elliptical arcs, Bézier curves and fill of the closed circuit with the color and/or image. For the elementary figures the following operations are provided:

Figure shows a part of the screen with a frame containing the elementary figures.


Realization of the basic elementary figures in Vision (10 )

The figures underlying this widget, containing the points (the start and end ones) that can be connected with the according points of other figures; and the points with the help of which the geometry of the figure can be changed.


It is possible to add the figure using the mouse:

  1. Select the desired figure from the context menu.
  2. Set with the left mouse-button start and end points (for line with the SHIFT key hold its orthogonal drawing is made).

The deleting of the figure(s) it is possible by pressing "Del", having selected figure(s).


The copying of the figure(s) it is possible by pressing keys "Ctrl"+"C", having selected figure(s).


Moving/resizing of the figure it is possible by using the mouse or keyboard:

  1. Select the figure, by clicking on it with the left mouse button.
  2. Drag (with the help of mouse or control keys) the figure or one of its control points in the desired location and release the mouse button (key).

It is possible to move several figures, selected by means of holding "Ctrl" and clicking on the desired figures (this option works when the button Connections (Connections) is disabled) or by mouse selection.


The connection of the figures with each other it is possible by the following way:

  1. Press the Connections button.
  2. Select one of the figures and move its start or end point to the desired start or end point of the other figure so that it will get to the appeared circle, release the left mouse button. Connected figures are moving as well as the individual, the general point is moved for all connected figures, to which it refers(priority is given to the arc, two arcs can't be connected directly with each other ).

To fill the closed circuit from the figures it is possible with the following way:

  1. Press the Connections button.
  2. Create the closed circuit.
  3. Make the double-click of the left mouse button inside of it.

To delete the fill of the closed circuit it is possible from the context menu of the widget; by braking the closed circuit or by double-click of the left mouse button on the already existing filled space.


Rotation of the figure is made around the center of the widget.

6.4.5 Primitive of the construction of diagrams/graphs (Diagram)

The implementation on the data-model side (UI.VCAEngine) describes into the document's part 4.12.

UI.Vision


The diagrams construction element releases for types "Graph", "Spectrum" and "XY" with properties:


The module of visualizer provides and uses set of specific attributes of the generic means, its information are into next table. Theses attributes create by the visualizer, on its lack, at a first start.

Id Name Appointment
sclWin Scaling of a window selected part, by the mouse. It is logical type attribute created by the user manually at needs. The "true" value enables the scaling of a window selected part, by the mouse.

Support element of the report formation with the following properties is provided:


The basis of any document is XHTML-template. XHTML-template is the tag "body" of the WEB-page which contains the document's static in the standard XHTML 1.0 and elements of the executable instructions in one of the languages of the user programming of OpenSCADA in the form of <?dp {procedure} ?>. The resulting document is formed by the execution of procedures and insert of their result into the document.


The source for values of the executable instructions are the attributes of the widget of the primitive, as well as all the mechanisms of the user programming language. Attributes may be added by the user and they can be linked to the actual attributes or parameters or they can be autonomous, values of which will be formed in the script of the widget. In the case of linked attributes the values can be extracted from the history, archive.
