Lingo Dictionary 171
The cast member that you specify must be a 1-bit cast member. If the cast member is larger
than 16 by 16 pixels, Director crops it to a 16-by-16-pixel square, starting in the upper left
corner of the image. The cursor’s hot spot is still the registration point of the cast member.

Use the syntax
cursor whichCursor
to specify default system cursors. The term
whichCursor
must be one of the following integer values:
•
Use the syntax
cursor (member whichCursorCastMember )
for the custom cursors available
through the Cursor Xtra.
Be sure not to confuse the syntax
cursor 1
with
cursor [1]
. The first selects the I-beam from
the system cursor set; the second uses cast member 1 as the custom cursor.
Note: Although the Cursor Xtra allows cursors of different cast types, text cast members cannot be used as cursors.
During system events such as file loading, the operating system may display the watch cursor and
then change to the pointer cursor when returning control to the application, overriding the
cursor
command settings from the previous movie. To use
cursor
at the beginning of any new
movie that is loaded in a presentation using a custom cursor for multiple movies, store any special
cursor resource number as a global variable that remains in memory between movies.
Cursor commands can be interrupted by an Xtra or other external agent. If the cursor is set to a
value in Director and an Xtra or external agent takes control of the cursor, resetting the cursor to
the original value has no effect because Director doesn’t perceive that the cursor has changed. To
work around this, explicitly set the cursor to a third value and then reset it to the original value.
Example
This statement changes the cursor to a watch cursor on the Macintosh, and hourglass in
Windows, whenever the value in the variable named status equals 1:
if status = 1 then cursor 4
This handler checks whether the cast member assigned to the variable is a 1-bit cast member and
then uses it as the cursor if it is:
on myCursor someMember
if the depth of member someMember = 1 then
cursor[someMember]
else
beep
end if
end
