This driver writes to a QPicture graphics metafile. The frame() call of this class invokes a modal dialog QDisplayDialog that "plays" the metafile in the display window.
Usage:
A program that uses this driver is required to include the two header files QTsupport.h and Qdriver.h
The program must be linked to the EclipseConsoleGraphics library.

Draws a connected set of line segments. The segment endpoints are specified by (X[0],Y[0]), (X[1],Y[1]), ..., (X[npoints-1],Y[npoint-1]).
| X | A double array of the x-coordinates of the segment endpoints (values in [0,1]) | |
| Y | A double array of the y-coordinates of the segment endpoints (values in [0,1]) | |
| npoints | The number of segment endpoints (typically the size of the X and Y arrays). | |
| dash_pattern | One of the enumerated dash constants. A value of 0 (default) for dash_pattern corresponds to a solid line. If equal to USER_DASH then the parameter user_pattern sets the dash pattern. | |
| user_pattern | The last two bytes of this parameter are used to represent the dash pattern if dash_pattern = USER_DASH. | |
| width | The width of the line as a fraction of the drawing window width. For example, in the PostScript representation the default is 0.001. Passing a value of 0 for width causes the default to be used. | |
| color | One of the enumerated color constants values specifying the color of the line. If color == 0 the default color is used. If color == USER_RGB then the parameter RGB is used to set the color. | |
| RGB | A three element double array with values between 0 and 255 specifying the red, green and blue components of the color. |

Draws the character c at a collection of points. The coordinates of the points are specfied by the values in the X and Y arrays; e.g. (X[0],y[0]), (X[1],Y[1]), ..., (X[npoint-1],Y[npoints-1]).
| X | A double array of the x-coordinates of point locations (values in [0,1]) | |

Draws the string s at the reference point (x,y).
| x | The x-coordinate of the point (a value in [0,1]) | |
| y | The y-coordinate of the point (a value in [0,1]) | |
| s | A character string containing the characters to be drawn. | |
| font | A character string specifying the font to be used. If font == 0 the default font is used. | |
| size | The relative size of the characters with respect to the drawing window. If size == 0, the default size value is used. | |
| rotation | The rotation of the string about the reference point in a counterclockwise direction. The angle is specified in degrees. | |
| horiz_just | The horizontal alignment of the string about the reference point. A values of 0 causes the string to be horizontally centered about the reference point. A value of -1 causes the left edge of the string to be lined up with the reference point, a value of 1 lines up the right edge, and any other value the interpolation of these. For example, -0.5 causes the reference point to be located a forth of the string from the left edge of the string. Alignment is performed before any rotation. | |
| vert_just | The vertical alignment of the string about the reference point. A values of 0 causes the string to be vertically centered about the reference point. A value of -1 causes the top edge of the string to be lined up with the reference point, a value of 1 lines up the bottom edge, and any other value the interpolation of these. For example, -0.5 causes the reference point to be located a forth of the string from the top edge of the string. Alignment is performed before any rotation. | |
