Constructor Detail

DrawableSymbol

protected DrawableSymbol()

Konstruktor.

DrawableSymbol

public DrawableSymbol(int px,
                      int py,
                      java.lang.String presName)

Konstruktor für Symbol.

Parameters:

px - x-Koordinate

py - y-Koordinate

presName - Name des Darstellungsobjekts

DrawableSymbol

public DrawableSymbol(int x,
                      int y,
                      java.lang.String presName,
                      int pMinScale,
                      int pMaxScale)

pMaxScale - Maximal-Maßstab zum Zeichnen

Method Detail

drawProtected

protected void drawProtected(java.awt.Graphics g,
                             int scale,
                             int mode,
                             int pvalue)

Zeichnet das Symbol im Graphic Context g, vorausgesetzt der aktuelle Maßstab wird eingehalten.

Specified by:

drawProtected in class Drawable

Parameters:
