/*@C

367

PetscViewerDrawOpen - Opens a window for use as a PetscViewer. If you want to

368

do graphics in this window, you must call PetscViewerDrawGetDraw() and

369

perform the graphics on the PetscDraw object.

370

371

Collective

372

373

Input Parameters:

374

+ comm - communicator that will share window

375

. display - the X display on which to open, or null for the local machine

376

. title - the title to put in the title bar, or null for no title

377

. x, y - the screen coordinates of the upper left corner of window, or use PETSC_DECIDE

378

- w, h - window width and height in pixels, or may use PETSC_DECIDE or PETSC_DRAW_FULL_SIZE, PETSC_DRAW_HALF_SIZE,

379

PETSC_DRAW_THIRD_SIZE, PETSC_DRAW_QUARTER_SIZE

380

381

Output Parameters:

382

. viewer - the PetscViewer

383

384

Format Options:

385

+ PETSC_VIEWER_DRAW_BASIC - displays with basic format

386

- PETSC_VIEWER_DRAW_LG - displays using a line graph

387

388

Options Database Keys:

389

PetscViewerDrawOpen() calls PetscDrawCreate(), so see the manual page for

390

PetscDrawCreate() for runtime options, including

391

+ -draw_type x or null

392

. -nox - Disables all x-windows output

393

. -display <name> - Specifies name of machine for the X display

394

. -geometry <x,y,w,h> - allows setting the window location and size

395

- -draw_pause <pause> - Sets time (in seconds) that the

396

program pauses after PetscDrawPause() has been called

397

(0 is default, -1 implies until user input).

Note for Fortran Programmers:

402

Whenever indicating null character data in a Fortran code,

403

PETSC_NULL_CHARACTER must be employed; using NULL is not

404

correct for character data! Thus, PETSC_NULL_CHARACTER can be

405

used for the display and title input parameters.
