PetscViewerDrawOpen

Opens a window for use as a PetscViewer. If you want to do graphics in this window, you must call PetscViewerDrawGetDraw() and perform the graphics on the PetscDraw object.

Synopsis

#include "petscdraw.h" 
#include "petscviewer.h" 
PetscErrorCode  PetscViewerDrawOpen(MPI_Comm comm,const char display[],const char title[],int x,int y,int w,int h,PetscViewer *viewer)
Collective on MPI_Comm

Input Parameters

comm - communicator that will share window
display - the X display on which to open, or null for the local machine
title - the title to put in the title bar, or null for no title
x, y - the screen coordinates of the upper left corner of window, or use PETSC_DECIDE
w, h - window width and height in pixels, or may use PETSC_DECIDE or PETSC_DRAW_FULL_SIZE, PETSC_DRAW_HALF_SIZE, PETSC_DRAW_THIRD_SIZE, PETSC_DRAW_QUARTER_SIZE

Output Parameters

viewer -the PetscViewer

Format Options

PETSC_VIEWER_DRAW_BASIC - displays with basic format
PETSC_VIEWER_DRAW_LG - displays using a line graph

Options Database Keys

PetscViewerDrawOpen() calls PetscDrawCreate(), so see the manual page for PetscDrawCreate() for runtime options, including
-draw_type x or null- . -nox - Disables all x-windows output
-display <name> - Specifies name of machine for the X display
-geometry <x,y,w,h> - allows setting the window location and size
-draw_pause <pause> - Sets time (in seconds) that the program pauses after PetscDrawPause() has been called (0 is default, -1 implies until user input).

Note for Fortran Programmers

Whenever indicating null character data in a Fortran code, NULL_CHARACTER must be employed; using NULL is not correct for character data! Thus, NULL_CHARACTER can be used for the display and title input parameters.
