Screen

A pointer to a Screen structure

Flags

Set to one of SPOS_RELATIVE, SPOS_ABSOLUTE, or SPOS_MAKEVISIBLE. You may additionally set SPOS_FORCEDRAG if you need. Use SPOS_RELATIVE (zero) for normal use (move screen a relative amount expressed by x1,y1). Set the SPOS_ABSOLUTE flag if you wish x1 and y1 to be absolute coordinates to move the screen to. Set SPOS_MAKEVISIBLE to position an oversized scrolling screen so that the rectangle described by (x1,y1)-(x2,y2) is on the visible part of the display. (A word-processor may wish to support autoscrolling as the user types. In that case, it could call ScreenPosition() with the SPOS_MAKEVISIBLE flag and a rectangle that encompasses the cursor with some space around it. In addition to any one of the above choices, you can additionally set SPOS_FORCEDRAG if you wish to reposition a screen that was opened with the [SA_Draggable, False] attribute.

X1

Absolute position or change in position you wish to apply to the screen, when using SPOS_ABSOLUTE or SPOS_RELATIVE.

Y1

When using SPOS_MAKEVISIBLE, these variables describe the upper-left corner of the rectangle you would like to ensure is on the visible part of a scrolling screen.

X2

Ignored when using SPOS_ABSOLUTE or SPOS_RELATIVE. When using SPOS_MAKEVISIBLE, these variables describe the lower-right corner of the rectangle you would like to ensure is on the visible part of a scrolling screen.

Y2

Note that these coordinates are in the same resolution as the screen.

MoveScreen

Attempt to move the screen by the increments provided.
