XgrConvertWindowToDisplay() converts window coordinates (xWin,yWin) to display coordinates (xDisp,yDisp) for the window that contains grid .

XgrConvertWindowToGrid() converts window coordinates (xWin,yWin) to (xGrid,yGrid) grid coordinates for grid . 

XgrConvertWindowToGrid() converts window coordinates (xWin,yWin) to (x,y) local coordinates for grid . 

XgrConvertWindowToScaled() converts window coordinates (xWin,yWin) into (x#,y#) scaled coordinates for grid . 

XgrCreateGrid() creates a new grid in window, returns its grid number, initializes its settings to default values, then initializes its (gridType,parent,func) settings.

The upper-left corner of grid is set to:

(x,y) Local Coordinates of parent grid/window (locates grid-box)
(0,0) Local Coordinates
(0,0) Grid Coordinates 
(0#,0#) Scaled Coordinates

while the lower-right corner of grid is set to:

(width-1, height-1) Local Coordinates
(width-1, height-1) Grid Coordinates
(1#, 1#) Scaled Coordinates

XgrDestroyGrid() destroys grid, and make the grid number available. If grid is bufferGrid in other grids, bufferGrid is set to 0 in those grids. If grid is an image grid type, its memory image is freed.

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

XgrGetGridBorderOffset() returns the current border offset from the left , top , right , and bottom of grid that controls where the border is drawn by the XgrDrawBorder() functions.

XgrGetGridBox() returns the display coordinates of the upper-left and lower-right corners of the grid-box for grid in (x1Disp,y1Disp:x2Disp,y2Disp) . 

XgrGetGridBoxGrid() returns the grid coordinates of the upper-left and lower-right corners of the grid-box for grid in (x1Grid,y1Grid:x2Grid,y2Grid) . 

XgrGetGridBoxLocal() returns local coordinates of the upper-left and lower-right corners of the grid-box for grid in (x1,y1:x2,y2) . 

XgrGetGridBoxScaled() returns the scaled coordinates of the upper-left and lower-right corners of the grid-box for grid in (x1#,y1#:x2#,y2#) . 

XgrGetGridBoxWindow() returns the window coordinates of the upper-left and lower-right corners of the grid-box for grid in (x1Win,y1Win:x2Win,y2Win) . 

XgrGetGridBuffer() returns in bufferGrid the image grid that is currently performing automatic buffering for grid . bufferGrid=0 if automatic buffering is not being performed. 

XgrGetGridCharacterMapArray() returns a copy of the character map array for the specified grid .

XgrGetGridCoords() returns parents local coordinates of the upper-left corner of grid in x,y, and the local coordinates of the (upper-left:lower-right) corners of grid in (x1,y1:x2,y2) .

XgrGetDrawingMode() returns the current drawingMode for grid, including (lineStyle,lineWidth) . 

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.

XgrGetGridFont() returns the font currently assigned to grid . font determines the typeface, character size, and drawing angle for text drawn in grid .

XgrGetGridFunction() returns the func address of the grid function currently assigned to grid . This is the function called by XgrProcessMessages() when it processes grid messages for grid .

XgrGetGridParent() returns the parent currently assigned to grid . Grids with parent=0 have no parent. Parentless grids are the only grids whose grid functions are called and sent Redraw messages by XgrRedrawWindow() .

XgrGetGridPositionAndSize() returns the local coordinates in its parent of the upper-left corner of the grid-box of grid in (x,y), and the width and height of the grid-box in (width,height) . 

XgrGetGridState() returns the state currently assigned to grid . state=0 disables grid . 

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.

XgrGetGridType() returns the gridType of grid . 

XgrGetGridWindow() returns the window that contains grid .
