XF_ALLOW_VARLINK
Setting this extended flag allows all edit fields in the dialog box to allow the
°
key to be activated within the dialog box and to paste results to the
edit field. If this flag or XF_VARLINK_SELECT_ONLY is not set, then when
°
is pressed in a dialog box, the dialog box will be closed and VAR-LINK
will be activated.
XF_NO_ALPHA_LOCK
On the TI
-
89, Alpha-Lock is turned on for all dialog boxes with edit fields. Setting
this extended flag disables this feature.
XF_VARLINK_SELECT_ONLY
This flag is similar to XF_ALLOW_VARLINK except that the user may not make
any variable changes inside VAR-LINK (like deleting, copying, renaming, or
locking variables).
11.4.3. Dialog Flags
Each dialog field has a flag byte that provides additional features explained in the
table below.
Flag Useable with these fields
DF_TAB_ELLIPSES EDIT, POPUP — Draw ‘. . .’ between label and
pop-up/edit box.

region when redrawn.

area underneath the dialog box when it is started,
DB_MEMFUL returned if it cannot.
