Help with NSButtonCell

Scripting Forums AppleScriptObjC and Xcode

I have a button cell that displays a graphic and then is duplicated horizontally and vertically based on numbers entered in a text field. My questions is, how to I reset the NSButtonCell image to nothing? I have added a button to clear and I am trying to use

myCell's setImage_()

but no luck.

Here is my code that works for setting the image and its parameters.

set myCell to current application's NSButtonCell's alloc()'s init()
		myCell's setBordered_(0)
		myCell's setBackgroundColor_(current application's NSColor's whiteColor())
		set newImpoImage to NSImage's alloc()'s initWithContentsOfFile_(ImageFile) --(ImpoImageFill)
		myCell's setImage_(newImpoImage)
		myCell's setImageScaling_(0)
		set stepVforPreview to (stepV's stringValue() as real)
		set stepHforPreview to (stepH's stringValue() as real)
		set StepMatrix to current application's NSMatrix's alloc()'s initWithFrame_mode_prototype_numberOfRows_numberOfColumns_({{0, 0}, {147, 142}}, 0, myCell, stepVforPreview, stepHforPreview)
		StepMatrix's setAutosizesCells_(1) --Makes the cells fill the whole frame of the matrix set in the init method
		myCell's setImageScaling_(0)
		StepMatrix's setTarget_(me)
		StepMatrix's setAction_("click")
		StepMatrix's setBackgroundColor_(current application's NSColor's lightGrayColor())
		StepMatrix's setDrawsBackground_(1)
		cView's addSubview_(StepMatrix)

If a method takes an argument, like setImage:, you can’t just leave the argument out – put missing value in there.
