-
- The SPX_MOS unit provides routines for reading the mouse inputs.
-
- ───────────────────────────────────────────────────────────────────────────
- Global Variables:
-
- visible TRUE if the mouse pointer is visiable.
- mousehere TRUE is a mouse is connected and the driver is installed
- mousewason TRUE if the mouse was on before the procedure MOUSEOFF was called
- nomouse same as MOUSEHERE (for compatability)
- mseshp SPX default small mouse pointer shape
-
- m1,m2,m3,m4 : integer; { scratch variables, can use for any purpose }
-
- ───────────────────────────────────────────────────────────────────────────
- procedure mset(var m1,m2,m3,m4:integer);
-
- For users who are familar with the mouse driver interrupt number, they
- can use this procedure for direct interrupt mouse calls.
-
- m1 = register AX
- m2 = register BX
- m3 = register CX
- m4 = register DX
-
- ───────────────────────────────────────────────────────────────────────────
- function mousereset:integer;
-
- Resets the mouse. Must be called first to use any of the other
- functions. Returns 0 if successful
- ───────────────────────────────────────────────────────────────────────────
- procedure mouseon;
-
- Turns on the mouse. (display)
- ───────────────────────────────────────────────────────────────────────────
- function mouseoff:boolean;
-
- Turns off the mouse. (hide)
- ───────────────────────────────────────────────────────────────────────────
- procedure getmouse(var m2,m3,m4:integer);
-
- Gets the mouse inputs
-
- m2 Mouse button mask. Bit set indicates mouse button is down.
- bit 0 set - button 1
- bit 1 set - button 2
- bit 2 set - button 3
- m3 Mouse current X position
- m4 Mouse current Y position
- ───────────────────────────────────────────────────────────────────────────
- procedure setmouse(m3,m4:integer);
-
- Move the mouse to a location.
-
- m3,m4 (x,y) position (in pixels) to move the mouse.
- ───────────────────────────────────────────────────────────────────────────
- procedure getmousepresses(var m2,m3,m4:integer);
-
- Get the number of mouse button presses. Since last call
-
- m2 number of presses.
- m3,m4 Mouse (x,y) position
- ───────────────────────────────────────────────────────────────────────────
- procedure getmousereleases(var m2,m3,m4:integer);
-
- Get the number of mouse button releases. Since last call
-
- m2 number of releases.
- m3,m4 Mouse (x,y) position
- ───────────────────────────────────────────────────────────────────────────
- procedure getmousemotion(var m3,m4:integer);
-
- Get the mouse motion
-
- m3 mouse horzontal speed. 0 = not moving horzontally
- m4 mouse vertical speed. 0 = not moving vertically
- ───────────────────────────────────────────────────────────────────────────
- procedure setmousecursor(m2,m3:integer; var mask);
-
- Set the mouse to a new shape.
-
- m2,m3 (x,y) offset of the mouse hot spot.
- mask 64 bytes describing the mouse shape. Maximum size of a cursor is
- 32x32. The first 32 bytes is a bit level mask. The next 32 bytes
- is the cursor shape. A bit set in the mask defines transparency. A
- bit set in the cursor shape defines white.
-
- ───────────────────────────────────────────────────────────────────────────
- procedure setmouseratio(m3,m4:integer);
-
- Set the mouse movement speed.
-
- m3 Set the horzontal speed
- m3 Set the vertical speed
- ───────────────────────────────────────────────────────────────────────────
- procedure setmouseoff(x1,y1,x2,y2:integer);
-
- Set a rectangular region which the mouse will not be displayed (if on)
-
- x1,y1 top-left position of rectangle
- x2,y2 bottom-right position of rectangle
- ───────────────────────────────────────────────────────────────────────────
- procedure setmousepage(f:byte);
-
- Sets the visual page of the mouse. (Does not work in 320x200x256 mode)
- ───────────────────────────────────────────────────────────────────────────
- procedure cleanmouse;
-
- Waits until not mouse button is pressed
- ───────────────────────────────────────────────────────────────────────────
- procedure chkmouseon;
-
- Displays the mouse if it was turned off by the procedure MOUSEOFF
- ───────────────────────────────────────────────────────────────────────────
- procedure setdefptr;
-
- Sets the mouse shape to the SPX default cursor arrow
- ───────────────────────────────────────────────────────────────────────────
