If this method is called after the component has been drawn/initialized: Updates the second cubic Bézier control point.- Parameters:
controlPoint2- left coordinate for control point, in pixels. Default value is [0,100]- Returns:
DrawCurveinstance, for chaining setter calls
-
getControlPoint2
Second cubic bezier control point.- Returns:
- Current controlPoint2 value. Default value is [0,100]
-
setEndPoint
End point of the curve
If this method is called after the component has been drawn/initialized: Update the endPoint- Parameters:
endPoint- left coordinate for end point, in pixels. Default value is [100,100]- Returns:
DrawCurveinstance, for chaining setter calls
-
getEndPoint
End point of the curve- Returns:
- Current endPoint value. Default value is [100,100]
-
setKnobs
Array of control knobs to display for this item. EachKnobTypespecified in this will turn on UI element(s) allowing the user to manipulate this DrawCurve. To update the set of knobs at runtime useDrawItem.showKnobs()andDrawItem.hideKnobs().DrawCurve supports the
KnobType.STARTPOINT,KnobType.ENDPOINT,KnobType.CONTROLPOINT1, andKnobType.CONTROLPOINT2knob types.- Overrides:
setKnobsin classDrawItem- Parameters:
knobs- New knobs value. Default value is null- Returns:
DrawCurveinstance, for chaining setter calls- Throws:
IllegalStateException- this property cannot be changed after the component has been created- See Also:
-

setShowTitleLabelBackground
public DrawCurve setShowTitleLabelBackground(boolean showTitleLabelBackground) throws IllegalStateException If thetitleLabelis showing, should thetitleLabelBackgroundbe created and placed behind thetitleLabel?This defaults to true for
DrawSectors and shapes that are not commonly filled (e.g.DrawLines).Note : This is an advanced setting

setShowTitleLabelBackgroundin classDrawItem- Parameters:
showTitleLabelBackground- New showTitleLabelBackground value. Default value is true- Returns:
DrawCurveinstance, for chaining setter calls- Throws:
IllegalStateException- this property cannot be changed after the component has been created

getShowTitleLabelBackgroundin classDrawItem- Returns:
- Current showTitleLabelBackground value. Default value is true

DrawCurveinstance, for chaining setter calls
-
getStartPoint
Start point of the curve- Returns:

-
getCenter
Get the center point of the rectangle from the curve'sstartPointto theendPoint. -
moveBy
public void moveBy(int x, int y) Increment start, end and control points of this curve -
moveStartPointTo
Move the start point, end point, and control points of the curve such that thestartPointends up at the specified coordinates and the shape of the curve is unchanged.- Parameters:
x- new x coordinate in pixelsy- new y coordinate in pixels
-
setDefaultProperties
Class level method to set the default properties of this class. If set, then all existing and subsequently created instances of this class will automatically have default properties corresponding to the properties set on the SmartGWT class instance passed to this function before its underlying SmartClient JS object was created. This is a powerful feature that eliminates the need for users to create a separate hierarchy of subclasses that only alter the default properties of this class. Can also be used for skinning / styling purposes.Note: This method is intended for setting default attributes only and will affect all instances of the underlying class (including those automatically generated in JavaScript). This method should not be used to apply standard EventHandlers or override methods for a class - use a custom subclass instead. Calling this method after instances have been created can result in undefined behavior, since it bypasses any setters and a class instance may have already examined a particular property and not be expecting any changes through this route.
- Parameters:
drawCurveProperties- properties that should be used as new defaults when instances of this class are created- See Also:
-
setLogicalStructure
Setter implementing theLogicalStructureinterface, which supports Eclipse's logical structure debugging facility. -
getLogicalStructure
Getter implementing theLogicalStructureinterface, which supports Eclipse's logical structure debugging facility.- Specified by:
getLogicalStructurein interfaceLogicalStructure- Overrides:
getLogicalStructurein classDrawItem
