You could add a button "Select this" to all open figures:
function pushbutton15_Callback(hObject, eventdata, handles)
openFig = get(groot, 'Children');
hButton = gobjects(1, numel(openFig));
hFig = ancestor(hObject, 'Figure');
for k = 1:numel(openFig)
hButton(k) = uicontrol(openFig(k), 'Style', 'PushButton', ...
'String', 'Select', ...
'Callback', {@selectBtn_Callback, handles, hFig});
end
setappdata(hFig, 'SelectButton', hButton);
end
function selectBtn_Callback(hObject, eventdata, handles, hFig)
hSelectedFigure = ancestor(hObject, 'Figure');
hButton = getappdata(hFig, 'SelectButton');
delete(hButton);
setappdata(hFig, 'SelectButton', []);
... do with hSelectedFigure what you want now
end
