Method Detail

isMenubarCircular

public boolean isMenubarCircular()

Description copied from interface: DSEngine

tells to DSMenubar which policy to choose to draw the border of the menubar

Specified by:

isMenubarCircular in interface DSEngine

transformTable

public AffineTransform transformTable(double d,
                                      double alpha,
                                      double beta,
                                      double scale,
                                      double tangle,
                                      double tzoom,
                                      int elType,
                                      int userid)

Description copied from interface: DSEngine

Return an AffineTransform object to apply to a Graphics2D before drawing an element.

Specified by:

transformTable in interface DSEngine

Parameters:

d - the distance from the center of the table to the center of the element. 0.5 means between the center and the border

alpha - the angle of the element. Angle around the center of the table (trigonometric system)

beta - angle around the center of the element

scale - the scale factor. may be modified by a blackhole or fisheye technique

tangle - the angle of the whole table to add it to Alpha. 0 when dragged and = angle of the view otherwise

tzoom - the scale of the whole table

elType - element type tells if the element is metalic or not then subject to magnetization !

userid - user id of the owner of element to transform

Returns:

a transformation matrix decribing the element rotations, scale, translation according to the parameter values

getDefMode

public int getDefMode()

setDefMode

public void setDefMode(int defMode)
