Method Detail

setUpdateRoot

public void setUpdateRoot(int ur)

set update root layer, i.e. the first layer that has to be updated via paintLayer(java.awt.Graphics, int). Note that after resize full repaint of all layers is done but updateRoot is not changed. It is safe (and sensible) to set the update root higher than the last layer; this will cause full repaint only on resize. such behavior is useful when the underlying paint doesn't change except for resizes. common practice is to the update root to # of layers at the end of the paintLayer function and use setUpdateRoot in the remaining program only where content of the painted are has to be explicitely changed. also note that changing update root during the update itself has no effect on the current update.

Specified by:

Parameters:

ur - root layer, i.e. the layer to start repaining from
