MATLAB: Dialog box’s Parent

Question

function tri
    f=figure(...
    'MenuBar','none',...   
    'Position',[400 200 600 445]...
);
m_file=uimenu('Label','File');
uimenu(m_file,'Label','New','Accelerator','N','Callback',{@new,f});
end
function new(hObject, eventdata, handle)
    d=dialog('Name','OPEN');
end

I want to set the d's parent as f figure. I wrote

d=dialog('Parent',handle,'Name','OPEN');

instead of this:

d=dialog('Name','OPEN');

But i'm getting an error:

Error using figure
While setting the 'Parent' property of Figure:
Figure parent must be the root.
Error in dialog (line 84)
hDialog = figure('ButtonDownFcn'    ,btndown   , ...
Error in den>new (line 10)
    d=dialog('Parent',handle,'Name','OPEN'); 
Error while evaluating Menu Callback

How can I fix this error and reach my aim?

Answer 1

You cannot do that. Dialog boxes are figures; you cannot set a figure (the dialog box) to be a child of another figure.
