MATLAB: Variable amount of checkboxes in listbox (programmatic GUI)

checkboxguilistboxvariable

I have in my programmatic GUI the following listbox:

        h.listbox = uicontrol('style','listbox','units','pixels',...
                              'position',[10,175,200,200],...
                              'string',components_index);

The entire program gives me the following output:

What I now want, is that in front of every stock, I have a checkbox. Keep in mind that the amount of stocks is variable.

Can anyone point towards a solution?

Thanks in advance,

Jonathan

I don't think that is possible with Matlab UI controls. However, if you don't mind doing some experimentation with undocumented controls, the following information on Yair Altman's excellent blog may help:

% Convert to a callback-able reference handle
jListbox = handle(jListbox, 'CallbackProperties');
% Set the mouse-movement event callback
set(jListbox, 'MouseMovedCallback', {@mouseMovedCallback,hListbox});
 
% Mouse-movement callback
function mouseMovedCallback(jListbox, jEventData, hListbox)
   % Get the currently-hovered list-item
   mousePos = java.awt.Point(jEventData.getX, jEventData.getY);
   hoverIndex = jListbox.locationToIndex(mousePos) + 1;
   listValues = get(hListbox,'string');
   hoverValue = listValues{hoverIndex};
 
   % Modify the tooltip based on the hovered item
   msgStr = sprintf('<html>item #%d: <b>%s</b></html>', hoverIndex, hoverValue);
   set(hListbox, 'Tooltip',msgStr);
end  % mouseMovedCallback

MATLAB: How to put a javacomponent in the app designer

Java components are not supported by AppDesigner or uifigures. This is not a temporary limitation - it is a fundamental outcome from the radically different technology of uifigures (browser webpages that display HTML and JavaScript components) compared to legacy figures (which where essensially Java windows and so could contain Java components). Because of this, this limitation is not expected to be resolved. EVER. You will need to find a non-Java component to fit your needs in AppDesigner/uifigures. Unfortunately, there is no simple replacement for the CheckBoxList that I am aware of. You might try to find a JavaScript component that implements this and then add it to the uifigure using the new uihtml function (R2019b). Alternatively, you could use javacomponent in a legacy figure, but note that this is expected to stop working in some not-too-distant future Matlab release.
