Any application can use the popup CDEF (not just connection/terminal/file transfer tools). It is CDEF 63 with appropriate variation codes as defined in the documentation. Also, when the control is created, the values specified as parameters to NewControl or in the template for GetNewControl for the control minimum, maximum, value, and refcon take on special meanings. On page 173 of the preliminary draft of the CommToolbox documentation (that went out with 1.0b2 of the software through APDA) in the Comm Toolbox Utilities section, there is a description of these fields. contrlValue - controls how the popup label/title is displayed (stylistic variations plus justification in the popup label/title area) contrlMin - resource ID of the menu to be "popped" up contrlMax - width of the popup title/label area procID - variation code plus CDEF ID * 16 (as per Control Manager specifications) variation codes 1 - constant control width - do not dynamically resize popup control if the menu resizes. Text will be truncated and ellipsized as appropriate 2 - use color QD if available. If there are mctb's in the system they will be used. If the control owner is a classic grafport and not a color grafport, the popup CDEF will create and destroy a color grafport to draw the colors without the annoying conversion to classic QD colors 4 - use the control refcon field as a resource type to do an AddResMenu to the menu 8 - use the window's font and size for drawing the popup control in its quiescent state as well as for drawing the menu. Hope this helps... +-------------------------------------------------------------------------+ | Disclaimer: Apple has no connection with my postings. | +-------------------------------------------------------------------------+ Byron Han, CommToolbox Designer "DeAnza 3 - R.I.P. - 10/17/89 5:04PM" Apple Computer, Inc. -------------------------------- 20525 Mariani Ave, MS 69L Internet: han@apple.COM Cupertino, CA 95014 UUCP:{sun,voder,nsc,decwrl}!apple!han -------------------------------- GENIE:BYRONHAN CompuServe:72167,1664 ATTnet: 408-974-6450 Applelink:HAN1 HAN1@applelink.apple.COM ---------------------------------------------------------------------------
