D=get(gca,'Children')

Please post such messages as text. Is this the complete message?
What does "I have a figure" exactly mean? A fig file or the code which creates the figure?

The error message looks like you are opening a .fig file but you do not have the required SizeChangeFcn. Then you can redefine the SizeChangeFcn at first:
FigH = openfig('File.fig');
FigH.SizeChangeFcn = [];
