116: #include <petscoptions.h>
117: PetscErrorCode PetscOptionsBegin(MPI_Comm comm,const char prefix[],const char title[],const char mansec[])
119: Collective
121: Input Parameters:
122: + comm - communicator that shares GUI
123: . prefix - options prefix for all options displayed on window (optional)
124: . title - short descriptive text, for example "Krylov Solver Options"
125: - mansec - section of manual pages for options, for example KSP (optional)
127: Level: intermediate
129: Notes:
130: The set of queries needs to be ended by a call to PetscOptionsEnd().
132: One can add subheadings with PetscOptionsHead().
134: Developer Notes:
135: PetscOptionsPublish is set in PetscOptionsCheckInitial_Private() with -saws_options. When PetscOptionsPublish is set the
136: loop between PetscOptionsBegin() and PetscOptionsEnd() is run THREE times with PetscOptionsPublishCount of values -1,0,1.
137: Otherwise the loop is run ONCE with a PetscOptionsPublishCount of 1.
138: + \-1 - PetscOptionsInt() etc. just call PetscOptionsGetInt() etc.
139: . 0 - The GUI objects are created in PetscOptionsInt() etc. and displayed in PetscOptionsEnd() and the options
140: database updated with user changes; PetscOptionsGetInt() etc. are also called.
141: - 1 - PetscOptionsInt() etc. again call PetscOptionsGetInt() etc. (possibly getting new values), in addition the help message and
142: default values are printed if -help was given.
143: When PetscOptionsObject.changedmethod is set this causes PetscOptionsPublishCount to be reset to -2 (so in the next loop iteration it is -1)
144: and the whole process is repeated. This is to handle when, for example, the KSPType is changed thus changing the list of
145: options available so they need to be redisplayed so the user can change the. Changing PetscOptionsObjects.changedmethod is never
146: currently set.
