WinCC OA EWOs

This chapter describes the different WinCC OA EWOs.

BackgroundCover.ewo

This is an easy to use "External Widget Object" that can be placed on top of other widgets (for example, buttons, check boxes, tabs) in order to cover them if necessary. You can find the EWO in wincc_oa_path//bin/widgets/.

Scheduler.ewo

The Scheduler.ewo is located in wincc_oa_path//bin/widgets/. It is required for the functionality of WinCC OA scheduler and is provided by the WinCC OA installation.

Figure 1. Scheduler.ewo

The scheduler ewo contains the following special properties:

  • backgroundOrigin: This property holds the origin of the object's background. The origin is either WidgetOrigin (the default), ParentOrigin, WindowOrigin or AncestorOrigin. This only makes a difference if the object has a background pixmap where case positioning matters.

  • header: the header of the object (in the figure above "Week schedule").

  • inhibitOverlap: If this property has been set to TRUE it will prevent two overlapping time bars being created.

  • numDays: number of the days shown in the schedule.

  • readOnly: TRUE or FALSE. By default, FALSE meaning that time bars can be drawn at runtime.

  • snapMinutes: Specifies a raster that allows a user to only draw or drag a bar within the set period (raster).

GIS Viewer EWO

The WinCC OA GIS Viewer EWO allows displaying and managing ESRI shapes files. You can display maps and add shapes to your maps.

The viewer was tailor-made to fit in with WinCC OA. Therefore, the GIS viewer provides various functions like:

  • Loading WinCC OA colorDB files. Therefore, the viewer understands WinCC OA colors including blinking colors,

  • A shape layer can be tied to WinCC OA _SumAlertPanel data point. Therefore, a shape will blink in case of an alarm of this data point,

  • The viewer understands the function dpQueryConnectSingle() and can perform a dpQueryconnect query and feed the results directly into the viewer.

The WinCC OA GIS Viewer does not come with any maps. ETM does not provide, or can not assist you, in getting ESRI shapes files. You may find free maps on the Internet or may have to purchase a map containing the appropriate information.

Figure 2. The WinCC OA GIS Viewer

See the chapter Introduction to GIS_Viewer for an introduction to the GIS viewer. You will find a list of all available GIS viewer functions at the end of the chapter Introduction to the GIS Viewer.

AttentionEffect.ewo

The AttentionEffect.ewo offers four different effects (animations) to draw the attention of a user at a given point in a panel.

The AttentionEffect.ewo you can find in your WinCC OA installation directory under /bin/widgets/.

With the extended attribute color1 the color (with/without "alpha"-transparency) of the effect can be set.

With the extended attribute effectType the effect type can be selected.

For an AttentionEffect.ewo three types of events can be defined: clicked(), doubleClicked(), rightMousePressed().

There are four effect types available, which are displayed in an endless loop in the panel:

WaterDrop
Sphere
FlashLight
RotatingRect
Note:

Under certain circumstances performance problems can occur if the AttentionEffectEWO is used. In this case, use the following config entries in the [attentionEffectEWO] section of the config file.

[attentionEffectEWO]
updateIntervalWaterDrop = 100
updateIntervalSphere = 150
updateIntervalFlashLight = 200
updateIntervalRotatingRect = 100

The values are specified in milliseconds. The minimum value is 40 milliseconds. 40 is also the default value. All values that are smaller than 40 milliseconds are automatically set to the default value of 40 milliseconds.

If not all of these config entries are set, the default value (40 milliseconds) is used for the missing entry. If the config entries are not specified or the section (attentionEffectEWO) is missing, the default value (40 milliseconds) is used.

Note:

When the AttentionEffect.ewo is added to a panel this is transparent. In the running panel the animation is not started until the start() command is called (see below). Therefore, add the object which should draw the attention of a user in the back of the EWO. In the figures above such an object is the rectangle.

Starting and stopping animations

In a running panel the animation is not started until the "start" command is called.

Example of a code for a Clicked event of a button to start all effects of a panel

main()
{
  dyn_string shapes = getShapes(myModuleName(), myPanelName(), "shapeType", "AttentionEffect_ewo");

  for (int i = 1; i <= dynlen(shapes); i++)
  {
    shape s = getShape(shapes[i]);
    s.start();
  }
}

An effect can be stopped with the stop() command.

Example of a code for a Clicked event of a button to stop all effects of a panel

main()
{
  dyn_string shapes = getShapes(myModuleName(), myPanelName(), "shapeType", "AttentionEffect_ewo");

  for (int i = 1; i <= dynlen(shapes); i++)
  {
    shape s = getShape(shapes[i]);
    s.stop();
  }
}

Figure 4. Example of a panel with stopped AttentionEffect.ewo EWOs

PictureFlow.ewo

The PictureFlow EWO provides the animated display of pictures and panels (strictly speaking the pictures of the panels). The pictures and panels are arranged in form of slides in the PictureFlow. The main slide is always in the middle. With a mouse click on a slide on the left hand side or on the right hand side of the main slide, the slides flow in the appropriate direction, and the next or previous slide becomes the main slide. A direct "jumping" to the e.g. third-next slide is not supported, i.e. the slide group on the right must be clicked three times to bring the third-next slide to front.

The PictureFlow.ewo you can find in your WinCC OA installation directory under /bin/widgets/.

Figure 5. Example of a PictureFlow EWO

The following example demonstrates the use of the available CTRL functions for the PictureFlow EWO. If you copy this script to the Initialize event of your PictureFlow EWO, and add a primitive text with the name "panelFileName" below the EWO, you will get the same PictureFlow as shown in the figure above.

dyn_string names;

main()
{
  //Defines the size of a slide in pixel
  this.slideSize = makeDynInt(150, 200);

  for (int i = 0; i < 1; i++)
  {

    /*Adds a new slide with a picture to the PictureFlow. The path to the picture is
    required, starting at the /pictures directory*/
    this.addSlide("PlantIcons/binocular_2.gif");

    /*Appends the path to the dynamic field names for later display in the "panelFileName" text field.*/
    dynAppend(names, "PlantIcons/binocular_2.gif");
    this.addSlide("PlantIcons/binocular_3.gif");
    dynAppend(names, "PlantIcons/binocular_3.gif");
    this.addSlide("PlantIcons/binocular_4.gif");
    dynAppend(names, "PlantIcons/binocular_4.gif");
    this.addSlide("PlantIcons/globe_1.gif");

    dynAppend(names, "PlantIcons/globe_1.gif");
    this.addSlide("PlantIcons/globe_2.gif");

    dynAppend(names, "PlantIcons/globe_2.gif");
    this.addSlide("PlantIcons/globe_3.gif");

    dynAppend(names, "PlantIcons/globe_3.gif");
    this.addSlide("PlantIcons/globe_4.gif");

    dynAppend(names, "PlantIcons/globe_4.gif");
  }

  //An empty slide without picture is added.
  anytype any;
  this.addSlide(any);
  dynAppend(names, "-empty-");

  /*Function call of addPanels() for integration of panel pictures from the /panels and /panels/examples directories */
  addPanels("");
  addPanels("examples");

  /*Defines the index of the slide (beginning with 0) which will be shown as main slide (i.e. in the middle) when the PictureFlow EWO is opened */
  this.centerIndex = 3;

  //Passes the stored path information to the text field
  panelFileName.text = names[1];
}

addPanels(string dir)
{
  anytype pixmap;

  //Determines the absolute path to the panel directories specified in main()
  string path = getPath(PANELS_REL_PATH, dir, getActiveLang(), SEARCH_PATH_LEN);

  //Stores the panel names
  dyn_string files = getFileNames(path);


  /*The picture of each panel is stored in the cache and added to separate slides of the PictureFlow EWO*/
  for (int i = 1; i <= dynlen(files); i++)
  {
    string cached = getPath(PICTURES_REL_PATH, "panel-cache/" + dir + "/" + files[i] + ".png");

    if ( cached == "" )
    {
      DebugN(i, dir + "/" + files[i], getPanelPreview(pixmap, dir + "/" + files[i], 0.5));
      mkdir(getPath(PICTURES_REL_PATH, "panel-cache/") + dir);
      imageToFile(pixmap, "panel-cache/" + dir + "/" + files[i] + ".png");
    }
    else
    pixmap = QVarPicture("panel-cache/" + dir + "/" + files[i] + ".png");
    
    dynAppend(names, dir + "/" + files[i]);
    this.addSlide(pixmap);
  }
}

CONTROL Functions

DateTimeEdit.ewo

The DateTimeEdit.ewo provides a widget for editing dates and times.

The DateTimeEdit.ewo allows the user to edit dates by using the keyboard or the arrow keys to increase and decrease date and time values. The arrow keys can be used to move from section to section.

You can find the DateTimeEdit.ewo in your WinCC OA installation directory under /bin/widgets/.

Figure 6. DateTimeEdit.ewo

Using the calenderPopup property of the DateTimeEdit.ewo it is possible to enable or disable the calender popup, which can be used to select a specific date (see figure "DateTimeEdit.ewo + calender popup").

Figure 7. DateTimeEdit.ewo + calender popup

The values of the DateTimeEdit.ewo (date and time) are internally stored as "time" data type.

The DateTimeEdit.ewo provides special properties that are described in the following:

  • date: Returns the selected date. The time value equals 0.

  • time: Returns the selected time. The date value equals the 1.1..1970. Caution: This property can only be used with getValue().

  • dateTime: Returns date and time.

  • displayFormat: Allows to define the output format of date and time.

  • todayDisplayFormat: Allows to define the output format of the "Today" value inside the calender popup.

  • calenderPopup: Allows to display the calender popup. A value of "true" means, that the popup will be displayed whereas a value of "false" indicates that the popup will not be used.

Note:

Please note that the calender popup is only displayed if a valid date format is stated which allows the selection of day/month/year.

Additionally for displaying the "Go to Today" button the calenderPopup must be explicitly set to "true" after changing the display format to a valid date format. Otherwise this button is not available.

Note: The date / time format of the DateTimeEdit.ewo differs from the format that is used inside of CTRL.

In the following the format expressions for the DateTimeEdit.ewo are described.

EWO Events

Following Events are available for the EWO:

Event EWO Specific Behavior
initialized() -
acknowledge() -
keyboardFocusIn() -
keyboardFocusOut() -
langChanged() -
mouseOver(bool enter) -
changed(double dValue, bool bFinished) The event is triggered while changing the value either via the buttons or keyboard input. The event is triggered for each change and the passed dValue is updated accordingly while the bFinished is only changed to true if the mouse has been released, the keyboard focus has changed to a different object or the changes have been finished by using the enter key. The up and down key of the keyboard can also be used to increase/decrease the value. In this case releasing the corresponding key returns a true for bFinished. Also the mouse wheel can be used to change values. Note: If the value is set using CTRL then the event is not triggered!
doubleClicked(mapping event) -
rightMousePressed(mappig event) -
