Constructor Detail

MultiLineLabel

public MultiLineLabel(String label,
                      int margin_width,
                      int margin_height,
                      int alignment)

                      int margin_height)

Method Detail

setLabel

public void setLabel(String label)

setFont

public void setFont(Font f)

setForeground

public void setForeground(Color c)

setAlignment

public void setAlignment(int a)

setMarginWidth

public void setMarginWidth(int mw)

setMarginHeight

public void setMarginHeight(int mh)

getLabel

public String getLabel()

getAlignment

public int getAlignment()

getMarginWidth

public int getMarginWidth()

getMarginHeight

public int getMarginHeight()

getPreferredSize

public Dimension getPreferredSize()

This method is called by a layout manager when it wants to know how big we'd like to be.

getMinimumSize

public Dimension getMinimumSize()

This method is called when the layout manager wants to know the bare minimum amount of space we need to get by.

paint

public void paint(Graphics g)

This method draws the label (same method that applets use). Note that it handles the margins and the alignment, but that it doesn't have to worry about the color or font--the superclass takes care of setting those in the Graphics object we're passed.

newLabel

protected void newLabel()

This internal method breaks a specified label up into an array of lines. It uses the StringTokenizer utility class.

measure

protected void measure()

This internal method figures out how the font is, and how wide each line of the label is, and how wide the widest line is.
