    - "acceptDrops"
      Specifies whether drop events are enabled for this object.
    - "addRange"
      Adds a time bar to the scheduler ewo.
    - "backgroundOrigin"
      Returns the origin of the widget`s background. This attribute only makes a difference if the widget has a background pixmap, in which case positioning matters. You can also set the origin.
    - "cloneDay"
      Copies the time bar of a specific day to another day.
    - "color"
      Sets the color of the timeline or day header of the scheduler ewo.
    - "focus"
      The attribute "focus"; returns TRUEif the object has the focus.
    - "focusEnabled"
      Indicates whether the widget accepts keyboard focus.
    - "getDayColor"
      Returns the color of a scheduler ewo time bar.
    - "getDayText"
      Returns the title (text) of a specific day.
    - "getRangeColor"
      Returns the rangeColor of a scheduler time range (time bar).
    - "getRangeData"
      Returns the range data of a scheduler time range (time bar).
    - "getRangeDay"
      Returns the range day of a scheduler time range (time bar).
    - "getRangeEnd"
      Returns the range end of a scheduler time range (time bar).
    - "getRangeReadOnly";
      Returns either TRUE (a scheduler time range is read only) or FALSE (it is not read only).
    - "getRangeStart"
      Returns the range start of a scheduler time range (time bar).
    - "getRangeText"
      Returns the range text of a scheduler time range (time bar).
    - "header"
      Sets the header of a scheduler.ewo.
    - "inhibitOverlap"
      If this function is set to TRUE it prevents two overlapping time bars to be created.
    - "isActiveWindow"
      The attribute "isActiveWindow"; returns TRUE if this widget is the active window, otherwise FALSE.
    - "numDays";
      Sets the number of days for a scheduler ewo.
    - "numRanges";
      Returns the number of time ranges (time bar) for a scheduler ewo.
    - "ownCursor";
      The attribute "ownCursor" returns TRUE if an object (for example a textEdit, a tree widget, a slider, a zoom navigator or a thumb wheel) uses its own cursor. If the value is FALSE, the object uses its parent widget`s cursor.
    - "ownFont";
      The attribute "ownFont"; returns TRUE if an object (for example, a textEdit, a slider, a zoom navigator or a tree widget) uses its own font. If the value is FALSE, the object uses its parent widget`s font.
    - "position";
      Sets the position (X, Y) of a scheduler ewo.
    - "readOnly"
      Sets the scheduler ewo to read only (TRUE) or not to read only (FALSE).
    - "removeAllRanges"
      Deletes all available time ranges (time bars).
    - "removeRange"
      Deletes a specific time range (time bar).
    - "setDayColor"

    - "setDayText"
      Sets the text of a day for the scheduler ewo.
    - "setRangeColor"
      Sets the rangeColor of a scheduler time range (time bar).
    - "setRangeData"
      Sets the data of a scheduler time range (time bar).
    - "setRangeDay"

    - "tooltipDuration"
      Specifies how long a tooltip is shown.
    - "underMouse"
      Returns TRUE if a widget (textEdit, slider, thumb wheel, tree widget, zoom navigator, LCD number or progress bar) is beneath the cursor.
    - "updatesEnabled"
      This attribute specifies whether updates of a widget (for example, a textEdit, slider, progress bar, zoom navigator, LCD number or thumb wheel) have been enabled.
    - "x", "y"
      The attributes x and y return the coordinate of an object (e.g. a textEdit, a progress bar, a slider, a zoom navigator, an LCD number or a thumb wheel). x returns the X coordinate of an object. y returns the Y coordinate of an object.
