I've got a dialog box that contains several static and edit text fields that I'd like to "grey out" or show normally depending on what user selects from a set of radio buttons. Is there a simple equivalent to HiliteControl that can be used with text fields? If it would be easier, I'd be willing to make the text fields visible or invisible. Would it be "cheating" to arrange for these fields to have the last N item numbers and include or omit them from the DITL by setting the item count in the first two bytes of the DITL resource? If this approach works, is it possible to patch the DITL while the dialog is active? Any tips, suggestions, code fragments, etc. will be greatly appreciated.

There are a couple of ways I can think of off-hand. Either: 1) Stick a userItem around the text to be greyed (one for each text Item). Then when you want to grey that item, just use a FillRect on the userItem's rect with penmode patBic with grey. That should "dim" the text. 2) Use the Dialog Manager's routines Hide/Show DItem documented in IM IV I believe. These routines just hide the item (by moving them out of the dialog's visRgn). > Thanks, Barry Wolman You're welcome, Dan /-------------------------------------------------------------------------\ | Dan Weisman - University of Miami - Florida | || || || || | |--------------------------------------------------| || || ||\ /|| | | INTERNET -----> dweisman@umiami.IR.Miami.edu | || || || | || | | BITNET -----> dweisman@umiami | ||||||| || | || | |-------------------------------------------------------------------------| | "...the fact is- this friction will only be worn by persistance." -RUSH | \_________________________________________________________________________/

If the item is an editText item you should also change its type to a static text item. This should prevent a tab from moving the insertion point to the grayed out or invisible item; notice that it may be a little trickier do keep the item from responding to tabs than just changing its type. The routines Hide/Show DItem don't move an item out of the dialog's visRgn, they move it out of the dialog's portRect.
