ManyMouse

There doesn't seem to have been much in the way of interfaces for using ManyMouse - which as the name suggests, allows you to use more than one mouse in a program - hence this post.

I've got a small C interface up and running for use in BlitzMax, as well as using the original routines for initialising the interface.

First, the test program :

SuperStrict

Import "manymouse.c"
Import "macosx_hidmanager.c"
Import "macosx_hidutilities.c"
Import "windows_wminput.c"
Import "linux_evdev.c"
Import "x11_xinput.c"
Import "BlitzMaxManyMouseInterface.c"

Const MANYMOUSE_EVENT_ABSMOTION:Int = 0
Const MANYMOUSE_EVENT_RELMOTION:Int=1
Const MANYMOUSE_EVENT_BUTTON:Int=2
Const MANYMOUSE_EVENT_SCROLL:Int=3
Const MANYMOUSE_EVENT_DISCONNECT:Int=4
Const MANYMOUSE_EVENT_MAX:Int=5

Extern
	Function ManyMouse_Init:Int()
	Function ManyMouse_Quit()
	Function ManyMouse_DeviceName:Byte Ptr(index:Int)
	Function manyMouse_BMInterface_PollEvent:Byte()
	Function manyMouse_BMInterface_ReturnDeviceID:Int()
	Function manyMouse_BMInterface_ReturnItem:Int()
	Function manyMouse_BMInterface_ReturnValue:Int()
	Function manyMouse_BMInterface_ReturnType:Int()
EndExtern

Local numMice:Int
Local loop:Int
Local device:Int
Local eType:Int
Local item:Int
Local value:Int

Graphics 640,480,32

numMice=ManyMouse_Init()

Print "Number Of Mice:"+numMice

For loop=0 To numMice-1
	Print deviceNameToString(loop)
	'Print "Mouse Name : "+ManyMouse_DeviceName(loop)
Next

While Not KeyHit(KEY_ESCAPE)
	Cls
	
	While manyMouse_BMInterface_PollEvent()
		device=manyMouse_BMInterface_ReturnDeviceID()
		eType=manyMouse_BMInterface_ReturnType()
		item=manyMouse_BMInterface_ReturnItem()
		value=manyMouse_BMInterface_ReturnValue()
		Select eType
			Case MANYMOUSE_EVENT_ABSMOTION
									DrawText "Mouse "+device+" absolute motion ",0,0
									If item=0
										DrawText "X:"+value,0,16
									Else
										DrawText "Y:"+value,0,16
									EndIf
			Case MANYMOUSE_EVENT_RELMOTION
									DrawText "Mouse "+device+" relative motion ",0,32
									If item=0
										DrawText "X:"+value,0,48
									Else
										DrawText "Y:"+value,0,48
									EndIf
			
			Case MANYMOUSE_EVENT_BUTTON
									DrawText "A Button has been pressed ("+device+"/"+item+")",0,64
									If value
										DrawText "Down",0,64+16
									Else
										DrawText "Up",0,64+16
									EndIf
									
			Case MANYMOUSE_EVENT_SCROLL
									DrawText "Scroll wheel on mouse "+device,0,128
									If item=0
										DrawText "Vertical",0,128+16
										If value>0 
											DrawText "Up",0,128+32
										Else
											DrawText "Down",0,128+32
										EndIf
									Else
										DrawText "Horizontal",0,128+16
										If value>0
											DrawText "Right",0,128+32
										Else
											DrawText "Left",0,128+32
										EndIf
									EndIf
									
									
		EndSelect
	EndWhile
	
	Flip
EndWhile
ManyMouse_Quit()
End

Function deviceNameToString:String(index:Int)
Local temp:Byte Ptr
Local result:String
Local index2:Int
	
	result=""
	temp=ManyMouse_DeviceName(index)
	index2=0
	While temp[index2]<>0
		result:+Chr$(temp[index2])
		index2:+1
	EndWhile
	
	Return result
EndFunction

And the C interface program :

#include "ManyMouse.h"
#include "stdio.h"
#include "stdlib.h"

#ifndef TRUE
#define TRUE 1
#endif

#ifndef FALSE
#define FALSE 0
#endif

ManyMouseEvent event;

void manyMouse_BMInterface_Clear(void)
{
	memset(&event,(char) 0,sizeof(event));
}

char manyMouse_BMInterface_PollEvent(void)
{
	if (ManyMouse_PollEvent(&event))
	{
		return TRUE;
	}
	
	return FALSE;
}

int manyMouse_BMInterface_ReturnDeviceID(void)
{
	return event.device;
}

int manyMouse_BMInterface_ReturnItem(void)
{
	return event.item;
}

int manyMouse_BMInterface_ReturnValue(void)
{
	return event.value;
}

int manyMouse_BMInterface_ReturnType(void)
{
	return event.type;
}

ManyMouse works on Windows and Mac (Intel and should work on PPC). It should also work on Linux, but I haven't tried it yet.

ManyMouse itself can only be retrieved using SVN (unfortunately), but is availiable at http://icculus.org/manymouse/
