PetscViewerDrawOpen#
Opens a PetscDraw window for use as a PetscViewer with type PETSCVIEWERDRAW. 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
Input Parameters#
comm - communicator that will share window
display - the X display on which to open, or
NULLfor the local machinetitle - the title to put in the title bar, or
NULLfor no titlex - horizontal screen coordinate of the upper left corner of window, or use
PETSC_DECIDEy - vertical screen coordinate of the upper left corner of window, or use
PETSC_DECIDEw - window width in pixels, or may use
PETSC_DECIDEorPETSC_DRAW_FULL_SIZE,PETSC_DRAW_HALF_SIZE,PETSC_DRAW_THIRD_SIZE,PETSC_DRAW_QUARTER_SIZEh - window height in pixels, or may use
PETSC_DECIDEorPETSC_DRAW_FULL_SIZE,PETSC_DRAW_HALF_SIZE,PETSC_DRAW_THIRD_SIZE,PETSC_DRAW_QUARTER_SIZE
Output Parameter#
viewer - the
PetscViewer
Format Options#
PETSC_VIEWER_DRAW_BASIC- displays with basic formatPETSC_VIEWER_DRAW_LG- displays using a line graph
Options Database Keys#
-draw_type - use x or null
-nox - Disables all x-windows output
-display
- Specifies name of machine for the X display-geometry <x,y,w,h> - allows setting the window location and size
-draw_pause
- Sets time (in seconds) that the program pauses after PetscDrawPause() has been called (0 is default, -1 implies until user input).
Fortran Note#
Whenever indicating null character data in a Fortran code,
PETSC_NULL_CHARACTER must be employed; using NULL is not
correct for character data! Thus, PETSC_NULL_CHARACTER can be
used for the display and title input parameters.
