9.6 Refresh image
Gtkdialog can refresh an image in a <pixmap> widget without restarting the gui. Since the <input file> is static, we must change its content (by copy another file), and then refresh.export MAIN=' <window> <pixmap> <variable>IMAGE</variable> <input file>/root/image1.png</input> </pixmap> <button> <label>Change image</label> <action>cp -f /root/image2.png /root/image1.png</action> <action type="refresh">IMAGE</action> </button> </window>' gtkdialog --center --program=MAIN
