POSN

Description

Position Cursor X,Y or +X or +Y or X, Y, Name/Page. The cursor can be positioned on the display using absolute co-ordinates or moved in relation to its current position by using +/- offset values. The origin is located at the top left of the screen. Re-position a previously placed entity by specifying the new coo-ordinates and it's name. This can be useful for indicator bars, simple movement animations and moving text. It may be necessary to place the cursor on another page to create a new entity.


Syntax/Parameters POSN(X,Y,Name/Page)

  • IMG(name,src,style,x,y);
  • TEXT(name,text,style,x,y);
  • KEY(name,func,width,height,style,x,y); KEY(name,downFunc,upFunc,width,height,style,x,y); KEY(name,downFunc,upFunc,repFunc,width,height,style,x,y);
Example:
POSN(+25,+0);  moves the cursor 25 pixels to the right.
POSN(236,48); absolute position of x=236, y=48.
