Just remove the "()" to hand over the function itself (not the result of the function). --snip-- // the line win.form.bntLoginSubmit.addListener("execute", this.openKmpWin(),this); // has to be win.form.bntLoginSubmit.addListener("execute", this.openKmpWin, this); --snip-- since the "addListener" method expects a function as second parameter. In the line above you do *call* the function directly and end up with the result of the function which is "undefined" because your function does not have a return value. cheers, Alex > my source looks like this: > > makeLoginWin : function() > { > var win = new qx.ui.window.Window("Login", > "icon/16/apps/office-calendar.png"); > this.root.add(win); > win.form = new qx.ui.container.Composite(new qx.ui.layout.Grid(3,2)); > win.form.bntLoginSubmit = new qx.ui.form.Button("Login"); > win.form.bntLoginSubmit.addListener("execute", this.openKmpWin(),this); > win.form.add(win.form.bntLoginSubmit, {row: 2, column: 1}); > win.add(win.form); > return win; > }, > > openKmpWin : function() > { > alert("DEBUG"); > > }, > > I can't figure it out. > > regards > Mustafa Sak ------------------------------------------------------------------------------ Check out the new SourceForge.net Marketplace.
