XgrGridTypeNameToNumber() returns the gridType number previously assigned to gridType$ . If gridType$ was never registered, -1 is returned in gridType . 

XgrGridTypeNumberToName() converts gridType into the corresponding gridType$ . If gridType has not been assigned, an empty string is returned in gridType$ .

gridType=0 is "Coordinate" and gridType=1 is "Image".

XgrRegisterGridType() registers gridType$, assigns it a grid type number, and returns it in gridType . If gridType$ already exists, XgrRegisterGridType() returns the already established grid type number.

XgrSetGridBorder() sets the current grid border attribute that specifies the border style in the XgrDrawBorder() functions, plus additional border values borderUp , borderDown , borderFlags .

XgrSetGridBorderOffset() sets the current border offset from the left , top , right , and bottom of grid. These values determine how far the grid border is drawn from the edge of the grid by the XgrDrawBorder() functions.

XgrSetGridBox() sets the (upper-left:lower-right) of the grid-box to grid coordinates (x1Grid,y1Grid:x2Grid,y2Grid) . This does not change the position or size of the grid, and values of x2Grid,y2Grid that are inconsistent with grid width and height are adjusted to make them so.

XgrSetGridBoxScaled() sets the (upper-left:lower-right) corners of the grid-box to scaled coordinates (x1#,y1#:x2#,y2#) .

This does not change the position or size of the grid.

XgrSetGridBuffer() sets bufferGrid as the image grid to perform automatic buffering for grid . The grid type of bufferGrid must be image grid, which is 1 . bufferGrid = 0 means no buffer. 

XgrSetGridCharacterMapArray() sets the character map array for the specified grid .

XgrSetGridDrawingMode() sets drawMode for grid .

0 in drawingMode means SET drawing mode, where pixels are drawn with the specified color. 1 means XOR drawing mode, where pixels are drawn with the color generated by a bitwise XOR of the current pixel color and the specified color.

lineWidth,lineStyle may not be implemented.

XgrSetGridFont() sets the font that controls the typeface, point size, and drawing angle of text drawn in grid . 

XgrSetGridFunction() sets the func address of the grid function assigned to grid . XgrProcessMessages() calls this function when it processes a message for grid . 

XgrSetGridPositionAndSize() positions and resizes grid . The upper-left corner of its grid-box is set to parent local coordinates (x,y), and its (x2Grid,y2Grid) grid coordinates are adjusted if the size is changed.

XgrSetGridState() sets the disable/enable state of grid to state . state=0 disables grids.

GraphicsDesigner does not consider disabled grids in its search to find the grid to send mouse messages to, which effectively makes disabled grids invisible or non-existent to the mouse.

XgrSetGridTimer() sets a millisecond timer for grid to interval . When the timer counts down to zero it stops and a Timer message for grid is added to the message queue.

XgrSetGridType() sets the gridType of grid . This has no effect on the functionality of GraphicsDesigner, except that gridType=0 and gridType=1 grids do not receive event messages.
