add/remove buttons dynamically from gridFieldManager

[ Edited ]

before&laterHi there, i am trying to erase one button and add 2 new ones, in griedfieldManager but when i add tow new buttons, all fields inside the manager get moved to the right and that is the problems here is the code:

 

private void setChangeListener_btnSuscribe() {

		for (int i = 0; i < _listGridMngr.size(); i++) {

			final CustomImageButton _btnAddAux = (CustomImageButton) _listBtnAdd
					.elementAt(i);
			final GridFieldManager gridMgrAux = (GridFieldManager) _listGridMngr.elementAt(i);
			final CustomImageButton _btnFreeAux = (CustomImageButton) _listBtnFreeze
					.elementAt(i);
			final CustomImageButton _btnStopAux = (CustomImageButton) _listBtnStop
					.elementAt(i);
		//	final HorizontalFieldManager _hfmAux = (HorizontalFieldManager)_listHfmForGrid.elementAt(i);
			
			_btnAddAux.setChangeListener(new FieldChangeListener() {

				public void fieldChanged(Field field, int context) {
					gridMgrAux.deleteAll();
					//TODO sobreescribiendo la referencia quei esta el detalle,  ahy que modifiarla
					// o obenter el lugar donde esta contenida esta referencia para crear una nueva,
					gridMgrAux.add(new LabelField("name alert.."));
					gridMgrAux.add(_btnStopAux);
					gridMgrAux.add(_btnFreeAux);				

					gridMgrAux.setColumnProperty(0, GridFieldManager.FIXED_SIZE,
							(Display.getWidth() - (3 * Constants.IMG_SIZE) +5 ));

					gridMgrAux.setColumnProperty(1, GridFieldManager.FIXED_SIZE,
							Constants.IMG_SIZE);

					gridMgrAux.setColumnProperty(2, GridFieldManager.FIXED_SIZE,
							Constants.IMG_SIZE);

					gridMgrAux.setRowProperty(0, GridFieldManager.PREFERRED_SIZE,
							Constants.IMG_SIZE);
					gridMgrAux.invalidate();
					
				}
			});

		}
		// new RemoteApi().addLoyappty(serviceVo, _userId);

	}

Re: add/remove buttons dynamically from gridFieldManager

i think you should set the new size
exp:
the grid only has 2 place to insert field.
if you delete 1 field and insert another 2 field it will become 3 field but the grid only has 2 field...
maybe because of that.

and your image above dont show. i can see how you make it

Re: add/remove buttons dynamically from gridFieldManager

nop is alread have 3 slots, check the code 

gridMgr = new GridFieldManager(1, 3, 0);
		_listGridMngr.addElement(gridMgr);
		_hfmAlert = new HorizontalFieldManager(USE_ALL_WIDTH);
		_listHfmForGrid.addElement(_hfmAlert);
		gridMgr.add(_lblName);
		gridMgr.setColumnProperty(0, GridFieldManager.FIXED_SIZE,
				(Display.getWidth() - 3 * Constants.IMG_SIZE));

		gridMgr.setColumnProperty(1, GridFieldManager.FIXED_SIZE,
				Constants.IMG_SIZE);

		gridMgr.setColumnProperty(2, GridFieldManager.FIXED_SIZE,
				Constants.IMG_SIZE);

		gridMgr.setRowProperty(0, GridFieldManager.PREFERRED_SIZE,
				Constants.IMG_SIZE);
