we have managers in blackberry. implement toolbar on blackberry screen can use verticalfieldmanager , horizontalfieldmanager. if want toolbar show @ bottom can use verticalfieldmanager contains 1 fixed size verticalfieldmanager , 1 horizontalfieldmanager. can have toolbar buttons in horizontalfieldmanager , add parent manager.. this.

verticalfieldmanager parent =      new verticalfieldmanager(manager.use_all_height|manager.use_all_width); verticalfieldmanager vfm = new verticalfieldmanager(){     public void sublayout(int width, int height) {         super.sublayout(display.getwidth(), 300);         //force extent of our manager.         //this force height of object         //where above super.sublayout() call         //set width.         setextent(display.getwidth(), 300);     } };  /*  * add fields vfm  * buttonfield button = new buttonfield("button");  * vfm.add(button);  * ...  */ parent.add(vfm); horizontalfieldmanager hfm = new horizontalfieldmanager(); /*  * add toolbar buttons hfm  * hfm.add(icon1);  * hfm.add(icon2);  * ...  *   */ parent.add(hfm);
