If I erase axes(handles.axes2), the image appear in a new figure that opens independently from the project ! I want the image to remain in the same project ...
Function Button error : Not enough input arguments.

Hello
I have the following button:
%--------------Button-----------------------
btLinePropsPos = [0.81,0.08,0.12,0.1];
btLineprops = com.mathworks.mwswing.MJButton('Done');
btLineprops.setBorder([]);
btLineprops.setBackground( java.awt.Color.black);
btLineprops.setForeground(java.awt.Color.red)
btLineprops.setFont(java.awt.Font('Vivaldi',java.awt.Font.PLAIN,30))
btLineprops.setCursor(java.awt.Cursor(java.awt.Cursor.HAND_CURSOR));
btLineprops.setFlyOverAppearance(true);
btLineprops.setToolTipText('Create Truss');
[dummy,btContainer] = javacomponent(btLineprops,[0 0 1 1]); %#ok
set(btContainer, 'Units','Norm', 'Position',btLinePropsPos);
set(btLineprops, 'ActionPerformedCallback',@DoneCallback);
set(btContainer, 'Units','Norm', 'Position',btLinePropsPos);
-----------------------------------------
Then I click it : the followiing funtion should be done :
function DoneCallback(hObject, eventdata, handles)
global S
switch S
case 'Sloped Truss'
axes(handles.axes2);
imshow('shadedTruss.jpg');
case 'Vertical Truss'
axes(handles.axes2);
imshow('shadedTruss.jpg');
end
------------------------------
I am having the following error when axes(...) is reached :
*Error using Truss>DoneCallback (line 113)
Not enough input arguments.*
axes2 is created from outside, the problem here seems to be with handles because the variable S was a handles than when I turned it to global it worked but the error wasn't solved
any help ?
thank you

MATLAB never automatically passes handles to callbacks. GUIDE goes to the trouble of adding the handles parameter by setting the callback to a string that when executed fetches the handles and passes the two automatic parameters and the handles as well.
If you know that the button is on the same figure as the main gui, then code it with only two parameters, and then as the first thing in the callback do
handles = guidata(hObject);

As some temporary diagnostic code, before the imshow() call, add
fprintf(1, 'axes2 is %.16f, handle? %f, figure %.16f\n', h.axes2, ishandle(h.axes2), ancestor(h.axes2, 'figure'));
and after the imshow() add
drawnow()
and then run and tell us what the output is.

The position in pixels of -280 is asking to position a corner of the axes outside of the figure.
