I have a few list boxes in a GUI. It seems the default selection color is blue and when the list box is de-selected (clicking somewhere else), the selected text becomes gray.

Is there a way to have both of them remain blue without using "undocumented" matlab properties. Thanks in advance.

This cannot be done using documented features. Here's the undocumented way to do it:

1. Download my FindJObj utility from the File Exchange: http://www.mathworks.com/matlabcentral/fileexchange/14317-findjobj-find-java-handles-of-matlab-graphic-objects

2. Place the following in your Matlab code, when the focus is on the listbox:
jListbox = findjobj(hListbox);
jListbox=jListbox.getViewport.getComponent(0);
jListbox.setSelectionAppearanceReflectsFocus(0);

Note that action #2 "freezes" the current selection color, so if your listbox is not in focus when you run it, the gray selection color will remain even when the listbox is back in focus...
