Method Detail

setMinimumSize

public void setMinimumSize(java.awt.Dimension size)

setMaximumSize

public void setMaximumSize(java.awt.Dimension size)

Set the largest size at which this Widget can reasonably be drawn. When a WidgetContainer lays out its contents, it will attempt never to make this Widget larger than its maximum size.

setPreferredSize

public void setPreferredSize(java.awt.Dimension size)

Set the preferred size at which this Widget will look best. When a WidgetContainer lays out its contents, it will attempt to make this Widget as close as possible to its preferred size.

isOpaque

public boolean isOpaque()

setOpaque

public void setOpaque(boolean opaque)

Set whether this Widget should be opaque. If true, then it will be filled with its background color before RepaintEvents are sent out. If false, the parent container will show through.
