//  This routine puts up an alert using the StandardAlert routine. It first

//  requests information via a dialog. It uses a 'dlog' resource for this

//  dialog and has embedding enabled. After reviewing the DITL in ResEdit

//  and looking at the code below, it should provide some good clues as to

//  how you can take advantage of embedding features. You'll notice that I've

//  used it implicity below when I disable the contents of the secondary

//  groups containing the 'Use Default' check box and the button name edit

//  text box. This allows me to properly save the state of the Use Default

//  check box when checking and unchecking the 'Button <n>' check boxes. If I

//  had the 'Use Default' check box off when I click the Button 2 check box

//  off, the next time I turn the Button 2 check box on, the Use Default button

//  will still be enabled.

//

//  You'll also notice just how easy it is to disable edit text fields here.

//  Its just a call to the utility to enable/disable a dialog item. When in

//  embedding mode, all items are controls, so you can treat everything the

//  same way!

//

//  This routine also shows an example of the SetControlFontStyle routine,

//  which allows you to set the font of any control that supports font

//  styles. All new controls delivered with appearance that display text

//  obey the new font style doodad. Alternatively, we could have created a

//  'dftb' resource to set the font styles.
