Swing - JSplitPane setDividerLocation(double) problem

[nik_meback]

I need to set the divider location of my JSplitPane as a percentage of its size.

To divide the splitpane into two equal halves, I tried using:
mySplitPane.setDividerLocation((double)0.5);

but it just doesn't have any effect on the existing divider location.

Have you read the API for that method?
If the split pane is not correctly realized and on screen, this method will have no effect

To get better help sooner, post a SSCCE (Short, Self Contained, Compilable and Executable) example that demonstrates the problem.

If I may ask, what does it mean to get a pane "realized"? Is it something related to its visibility? Thanks.

realized: made real. As I understand it, a GUI component is realized when it is attached to native resources. For lightweight (Swing) components, this happens when the top-level window is either pack()ed or setVisible(true). The component will return to the unrealzed state if the containing window is dispose()d.
