@hovercraftfullofeels helped create code, what best way add button selects of ellipses , changes color inactive_color active_color.
my approach add button button panel , define action performed.
trying add functionality drawpanel2 class not accessible. possible best way this?
as always, other suggested improvements appreciated, thanks.

because can have multiple drawpanel2 instances , each 1 contained within it's own "tab", need find selected tab , extract drawpanel2 instance it, example
private class activateallaction extends abstractaction { public activateallaction(string name) { super(name); int mnemonic = (int) name.charat(1); putvalue(mnemonic_key, mnemonic); } @override public void actionperformed(actionevent e) { //add code performing action here component comp = tabbedpane.getselectedcomponent(); if (comp instanceof drawpanel2) { drawpanel2 drawpanel = (drawpanel2) comp; } } } this first checks see if selected tab component instance of drawpanel2, before casts it.
next, need way change state of ellipses...
to end, added activateall method drawpanel2 class, add 1 allows pass boolean sets the state instead
public void activateall() { (ellipse2d ellipse : ellipses) { ellipsecolormap.put(ellipse, active_color); } repaint(); } then action, called it
//... drawpanel2 drawpanel = (drawpanel2) comp; drawpanel.activateall();
