3 The changeme_dialog_Open ingFcn centers the Text Change dialog box

over the main GUI, using the passed-in handle to that figure. So, if the

main figu re is moved and the d ialog box is invoked, it opens in the same

relative position instead of always in a fixed locatio n.

eventdata, ha ndle s, varargin)

mainGuiInput = find(strcmp(varargin, 'changeme_main'));

handles.changeMeMain = varargin {mainGuiInput+1};

% Position to be relative to parent:

parentPosition = getpixelposition(handles.changeMeMain );

currentPosition = get(hObject, 'Position');

% Sets the position to be directly centere d on the main figu re

newX = parentPosition(1) + (parentPosition(3)/2 ...

- currentPositi on(3 )/2);

newY = parentPosition(2) + (parentPosition(4)/2 ...

- currentPositi on(4 )/2);

newW = currentPosition(3);

newH = currentPosition(4);
