@BeanProperty(description="The location of the divider.")
public void setDividerLocation (double proportionalLocation)

Sets the divider location as a percentage of the JSplitPane's size.

This method is implemented in terms of setDividerLocation(int). This method immediately changes the size of the split pane based on its current size. If the split pane is not correctly realized and on screen, this method will have no effect (new divider location will become (current size * proportionalLocation) which is 0).

Parameters:
proportionalLocation    a double-precision floating point value that specifies a percentage, from zero (top/left) to 1.0 (bottom/right)

Exceptions:
IllegalArgumentException    if the specified location is < 0 or > 1.0
