Hi all,
something puzzled me with qx 0.6.2 and I couldn't find anything related in
bugzilla:
A function creates a button and adds an event listener (in this "anonymous
inner method"-way, or whatever you'd call that in JavaScript). Now the event
handler modifies a variable 'tableModel' defined in the same function.
In the source tree everything works fine no matter if I declare 'tableModel'
before or after adding the listener (why that should work at all, I don't
know, since I don't come to terms with variable-scope in JavaScript :). The
build version, however, only works if I declare 'tableModel' *before* adding
the listener to the button.
Here's the code:
qx.OO.defineClass("bug1.Application", qx.component.AbstractApplication,
function () {
qx.component.AbstractApplication.call(this);
});
createTestPanel = function() {
// create a button with an event listener modifying a table model
var submit = new qx.ui.form.Button("Submit");
submit.addEventListener("execute", function(e) {
tableModel.setData([[1,"Company 1","City 1","Street 1"],
[2,"Company 2","City 2","Street 2"]]);
}, this);
// Define the table model and a table on top of it.
// FIX the problem by moving the next line of code
// before the definition of the button listener
var tableModel = new qx.ui.table.SimpleTableModel();
tableModel.setColumns(["Id","Name","City","Street"]);
var table = new qx.ui.table.Table(tableModel);
with (table) {
setWidth("100%");
setHeight(qx.constant.Core.FLEX);
setBorder(qx.renderer.border.BorderPresets.getInstance().thinInset);
};
// layout the widgets
var panel = new qx.ui.layout.VerticalBoxLayout();
with(panel) {
set({ left:10, top:10, right:10, bottom:10 });
setSpacing(10);
add(submit);
add(table);
}
return(panel);
}
qx.Proto.main = function(e) {
var d = qx.ui.core.ClientDocument.getInstance();
var panel = createTestPanel();
d.add(panel);
};
Regards,
Martin
