Need help using the Class DwtCheckbox

[ankurankan]

I am unable to insert a checkbox using DwtCheckbox class and am not sure how to do that. If someone could explain how to do that or just write an example code.
Thank you.

This is the code that treat as view params in zmdialog

var container = new DwtListView({parent:this.getShell(),noMaximize:false});
container.setSize("250", "150");
container.setScrollStyle(Dwt.SCROLL);
container.setPosition(DwtControl.RELATIVE_STYLE);

var view1 = new DwtComposite(container);
view1.setSize("250", "100");
view1.getHtmlElement().style.overflow = "auto";
view1.getHtmlElement().innerHTML = this._createSendDialogView();

this.check = new DwtCheckbox({parent:container,
						name:"approverSendEmaildialog_check",
						checked:true,
						posStyle:Dwt.RELATIVE_STYLE,
						id:"approverSendEmaildialog_check",
						index:1
						});
this.check.setText(locale_text_approverSendEmaildialog_check_value[this.localeId]);
this.check.setEnabled(false);
