NSColor opacity

[kel1]

Hi,

I’ve been trying many ways of changing a colors opacity with:

[NSColor colorWithDeviceRed:0.0 green:0.0 blue:1.0 alpha:0.5]

The current one I’m trying is:

set ac to current application’s NSColor’s colorWithDeviceRed_(0.3)green(1.0)blue(0.3)alpha(0.5)

What is the right way to write this in cocoa-applescript?

Here’s the whole handler:

on applicationDidFinishLaunching_(aNotification)
mainWindow’s setOpaque_(false)
set ac to current application’s NSColor’s colorWithDeviceRed_(0.3)green(1.0)blue(0.3)alpha(0.5)
mainWindow’s setBackgroundColor_(ac)
–mainWindow’s setAlphaValue_(0.5)
return
end applicationDidFinishLaunching_

Thanks,
kel

Took a short nap and think this might be it:

set ac to current application’s NSColor’s colorWithDeviceRed_green_blue_alpha_({0.3,1.0,0.3,0.5})

I’ll have to try it when I get back.

Wish me luck,

the parameters must not be a list

set ac to current application's NSColor's colorWithDeviceRed_green_blue_alpha_(0.3, 1.0, 0.3, 0.5)

Hi Stefan,

Yes, I rushed home to try it out and it works!

on applicationDidFinishLaunching_(aNotification)
        mainWindow's setOpaque_(false)
        set ac to current application's NSColor's colorWithDeviceRed_green_blue_alpha_(0.2,0.3,1.0,0.5)
        mainWindow's setBackgroundColor_(ac)
        --mainWindow's setAlphaValue_(0.5)
        return
    end applicationDidFinishLaunching_

Nice stuff.

Thanks,
