Classes developing

[andr213]

I am using:
SmartClient version 8.1.
Mozilla FireFox

I make the SmsHLayout class with some method and smartclient classes inside.

isc.defineClass("SmsHLayout", "HLayout");
isc.SmsHLayout.addProperties({
	testFunction: function (param){isc.say(param)},
	initWidget: function () {
		this.Super("initWidget", arguments);
		this.addMember(
			isc.IButton.create({
				size: 24,
				showRollOver: true,
				showDisabled: false,
				showDown: true,
				prompt: "RefreshData",
				hoverWrap: false,
				click: function (){SmsHLayout.testFunction('TESTFUNCTION');}
			})
		);
	}
});

I want to call the function "testFunction" by pressing the IButton. I tried using "this.testFunction()", "testFunction()", "SmsHLayout.testFunction()". But always
"TypeError: this.testFunction is not a function @ .../SmsLayout.js:676"

How can I Call "testFunction" function inside the class?

The problem seems to be inside function body, try to add semicolon:
testFunction: function (param){isc.say(param) ; },

The way you call it is on the class, not on the instance, what would need the method to be static (see addClassProperties). However, in your case, I assume you would rather have something like:

isc.defineClass("SmsHLayout", "HLayout");
isc.SmsHLayout.addProperties({
	testFunction: function (param){isc.say(param);},
	initWidget: function () {
		var me = this;

		this.members = [
			isc.IButton.create({
				size: 24,
				showRollOver: true,
				showDisabled: false,
				showDown: true,
				prompt: "RefreshData",
				hoverWrap: false,
				click: function (){ me.testFunction('TESTFUNCTION'); }
			})
		];

		this.Super("initWidget", arguments);
	}
});
