DialogName
is the name given to the dialog box structure. The generated .h file
is included to reference the dialog box from a C program.
DialogWidth
and
DialogHeight
define the width and height of the dialog box in pixels. If either or
both is zero, then the system will set them to the maximum values used by the
dialog box at the time the dialog box is executed.
CallBackRoutine
is the name of
the call-back function used for the dialog box. See section
11.4.4. Dialog
Call-Backs
for a description of call-backs.
Each item within the dialog structure has a
Flags
byte and an (x, y) coordinate of
the upper left pixel of the field. All coordinates in a dialog box are relative to the
upper left corner of the dialog box.
