Is it possible to get the window to resize at plugin startup? If I put it to any of the codes executed at startup (_start() function, dockables.xml bean shell code etc) I get a null pointer exception for view.getDockableWindowManager().getDockableWindow.(XYZPlugin.NAME).

I even tried capturing PluginUpdate message with another plugin, but that gives me the same exception.

Is there a way to get the handle of the window frame just after startup? In other words - is there a piece of code which gets executed after plugin initialization (where the handle is already available)?

Ok I finally did that.

JComponent c = view.getDockableWindowManager().getDockable(SideViewPlugin.NAME);
c.getTopLevelAncestor().setLocation(x,y);
//for maximizing
((JFrame)c.getTopLevelAncestor()).setExtendedState(JFrame.MAXIMIZED_BOTH);
