Hi!

The following code is used to create a list with checkBoxes. When I run the simulation the list and all the information related to the list are indicated on the workspace.

% First create the data model 
jList = java.util.ArrayList;  % any java.util.List will be ok 
jList.add(0,'First'); 
jList.add(1,'Second'); 
jList.add(2,'Third'); 
jList.add(3,'Forth'); 
jList.add(4,'Fifth'); 
jList.add(5,'Sixth'); 
jList.add(6,'and last'); 
% Next prepare a CheckBoxList component within a scroll-pane 
jCBList = com.mathworks.mwswing.checkboxlist.CheckBoxList(jList); 
jScrollPane = com.mathworks.mwswing.MJScrollPane(jCBList);
% Now place this scroll-pane within a Matlab container (figure or panel) 
[jhScroll,hContainer] = javacomponent(jScrollPane,[10,10,100,100],gcf); 
% Update some items' state programmatically 
% jCBModel = jCBList.getCheckModel; 
% jCBModel.checkAll; 
% jCBModel.uncheckIndex(1); 
% jCBModel.uncheckIndex(3); 
% % Respond to checkbox update events 
% jhCBModel = handle(jCBModel, 'CallbackProperties'); 
% set(jhCBModel, 'ValueChangedCallback', @myMatlabCallbackFcn);

I want to display the list by clicking on a pushbutton, so I add the above code to the function of a pushbutton as follows:

function pushbutton1_Callback(hObject, eventdata, handles) 
% First create the data model 
jList = java.util.ArrayList;  % any java.util.List will be ok 
jList.add(0,'First'); 
jList.add(1,'Second'); 
jList.add(2,'Third'); 
jList.add(3,'Forth'); 
jList.add(4,'Fifth'); 
jList.add(5,'Sixth'); 
jList.add(6,'and last'); 
assignin('base', 'jList', jlist); 
% Next prepare a CheckBoxList component within a scroll-pane 
jCBList = com.mathworks.mwswing.checkboxlist.CheckBoxList(jList); 
jScrollPane = com.mathworks.mwswing.MJScrollPane(jCBList);
