/* sendmydlg - SFPGetFIle item hit filter for "send file" dialog.
 *
 * This filter is called by SFPGetFile to let the programmer handle hits
 * on his custom items.  Our items are 2 sets of buttons for selecting
 * the fork (data or resource) and the transfer mode (binary or text).
 * Also we have an EditText item for filling in the AS name.
 *
 * The buttons are set when the user clicks, but they also are given
 * values depending on the selection of a file.  If the file's type is
 * "APPL" then controls "Resource" and "Binary" are automaticlly set,
 * otherwise the controls "Data" and "Text" are set.  SF-File keeps the
 * SFReply upto date when a file name is selected, but...  unfortunately
 * we are called before the SFReply is updated and so when we notice
 * "getNmList" is hit we defer our update for one cycle.
 *
 * Our other item, the TextEdit item to set the "AS" file name, can be
 * enabled or disabled to allow the selection of a file name by typing a
 * character (standard SFGetFile stuff).  By using the global flag
 * sendasflg and an event filter we switch between sending the chars to
 * SF-File for filename selection and to ModalDialog for TextEdit of our
 * AS name.  Since it would be nice to get rid of that blinking cursor
 * in the TextEdit item our DITL has an invisible EditText item which
 * becomes active for this purpose. 
 *
 * At startup the AS field is disabled (the invisible EditText is
 * current and sndasflg is FALSE).  The user can make AS active by
 * clicking in it.  The user can toggle by clicking on the StatText
 * "AS" -- though I won't tell anybody if you don't.
