      This attribute sets the space between the groove.
    - "contextMenuPolicy"
      Defines how the respective widgets shows the context menu.
    - "events" (obsolete)
      Gets all events that are available for a shape. Obsolete, use scriptNames instead.
    - "focus"
      The attribute "focus"; returns TRUEif the object has the focus.
    - "font"
      Sets the font of an object.
    - "frameShadow"
      The attribute "frameShadow" specifies the frame effect (3D effect) of an object (textEdit, progress bar, tree widget, thumb wheel, LCD number, DpTreeView or zoom navigator).
    - "frameShape"
      The attribute "frameShape" sets the style of an object frame (textEdit frame, a thumb wheel, a tree widget, a zoom navigator , an LCD number or a progress bar).
    - "frameWidth"
      The attribute "frameWidth"; returns the width of a frame (a textEdit, a tree widget, a zoom navigator, LCD number, a thumb wheel etc.)
    - "height"
      The attribute "height" returns the height of an object (textEdit, progress bar, tree widget, zoom navigator, LCD number or a thumb wheel.)
    - "invertedAppearance"
      Changes the direction of the slider into top = minimum value and bottom = maximum value.
    - "invertedControls"

    - "margin" - obsolete with version 3.12
      The attribute "margin" specifies the distance between the innermost pixel of the frame and the outermost pixel of the rectangle inside the frame.
    - "maximum"
      Defines the upper limit of the value range.
    - "maxValue";
      The attribute "maxValue"; sets the maximum value, which is returned when a slider is moved to maximum position. In case of thumb wheel the thumb wheel is moved between the minimum and maximum value.
    - "minimum"
      Defines the lower limit of the value range.
    - "minValue"
      The attribute "minValue"; sets the minimum value, which is returned when a slider is moved to minimum position. In case of thumb wheel the thumb wheel is moved between the minimum and maximum value.
    - "orientation";
      Sets the orientation of a slider, a thumb wheel, a progress bar or a spacer.
    - "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.

    - "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.
    - "value"
      Sets the current value of a thumb wheel.
    - "wrapsAround "
      Specifies that when the minimum of a thumb wheel is reached, the thumb wheel starts from the maximum.
    - "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.

Parameters


Parameter	Description
shape	Name of the object
limit	TRUE = the drag operation is stopped when the mouse is outside the widget's boundary FALSE = the drag operation is possible outside the widget's boundary
