 Posted: Sun Apr 17, 2005 8:04 am Post subject: Functions in non-expression parameters |
 |
|
I know that you could do something like
to call functions from non-expression parameters, but how do I do if there comes any parameters after the non-expression parameter, like:
| Code: |
Tooltip, % Add(3, 2), 200, 300
|
I know that functions is a very new part of AHK, so maybe I should do something more simple...

I guess you could put them in quotes "".

Hi GoG,
sorry, but I can't see your problem. Your tooltip example works pretty good 
| Code: | Tooltip, % Add(3, 2), 200, 300
Msgbox, test
Return
Add(x,y)
{
Return x+y
} |
The tooltip appears at the given postion and shows the result of the Add function.
Can you give me more details to understand your problem?
NiWi. |

Yes, the "% " prefix is designed to work on a per-parameter basis. Other (normal) parameters can follow it, and if you want, you can use "% " in more than one parameter of the same command.
The "% " prefix can also be used even when not required, which is useful in case you don't want to look up in the help file whether a certain parameter accepts expressions. In general, any parameter that always expects a pure number is expression-capable and doesn't require the "% " prefix. |

If it's true that you're saying, why doesn't this line work?
| Code: |
ToolTip, % (sin(A_Index) * r) + 400, % (cos(A_Index) * r) + 400, % (sin(A_Index) * r) + 400
|
Maybe it has something to do with my AHK version.
I have 1.0.31.00

try it like this, I got far enough through the errors that it was telling me it was trying to call a non-exsistant function so it will probably work for you since you have those functions.
| Code: | | ToolTip, (sin(A_Index)*r)+400, (cos(A_Index)*r)+400, (sin(A_Index)*r)+400 |
I think it was the extra spaces and % signs you had in there |

I don't want to be impolite, but that didn't work either.
The tooltip shows "(sin(A_Index)*r)+400" in stead of the result of the equation. 
ThanX anyway

| Since the first parameter of ToolTip is the text to be displayed, to use an expression in it you must include a "% " prefix. By contrast, its other parameters do not need the prefix (though it doesn't hurt to have it). |
