 Posted: Wed Jul 11, 2007 11:16 pm Post subject: How to detect if a particular mouse button is present? |
 |
|
I want the script that I'm writing to be prepared for all possible mouse buttons 1, 2, 3, 4.. that might be available.
The problem I have is that if I run my script and the particular mouse button I wrote a hotkey for is not present AHK will report a message box with an error.
Is there a way to either suppress these errors or check to see if the key is present before assigning the hotkey? |

perhaps you can use GetKeyState to see if its there. It should return blank for keys it can't get the state of.

You could place an interogation of the mouse with a check for errorlevel
You could nest these checks to determine which mouse to support and then branch to that form

Are you sure? My hotkey script uses XButton1 and XButton2 (among many others), and I have never had problems running it on systems that don't physically have these buttons. As long as you use the correct key/button names, you shouldn't get an error message. Although: | help: key list wrote: | Supported only in Windows 2000/XP or later:
XButton1 - a button that appears only on certain mice
XButton2 - a button that appears only on certain mice |
engunneer, GetKeyState returns blank only if the keyname can't be associated with a virtual key code (i.e. it's invalid, or not a recognized key name.) XButton1 and 2 are defined in the AHK source code, so GetKeyState will return 0 when they aren't pressed, even if they don't physically exist on the mouse.
If you're interested, key names are mapped to virtual keycodes by using the array g_key_to_vk, which is initialized in globaldata.cpp (of the AHK source code.)
| Code: | MsgBox, % "Your mouse has " . GetNumMouseButtons() . " buttons."
GetNumMouseButtons()
{
static SM_CMOUSEBUTTONS = 43
return DllCall("GetSystemMetrics", "int", SM_CMOUSEBUTTONS)
} |
Adapted from a VB example.  |

thanks for the clarification. It makes sense. I wonder what error the OPP was getting?

Running that code on my laptop produces 5 buttons, when I only have 3.
But I do have two mouse1's and two mouse2's which add up to five, but they are not 5 individual separate keys.

I had a feeling that wouldn't work... oh well. I thought to try DirectInput, but that reports 7 mouse buttons for me.  |
