This question could be made clearer and with less code attached. Are you asking how to display a string on a pushbutton control? Or you want a string to be used as an input in a pushbutton callback? Or something else?

Answer 2

[Fakhar Alam]

global x;

[a, b]=uigetfile();

x = strcat(b, a);

x = imread(x);

You can use also global variable .

call it against Pushbutton
