The Radio Buttons in 0.8.3pre do not allow you set a user defined value.
getValue() returns either true/false. setValue(userVal) throws an error if
userVal is not a boolean.
Assertion error! Invalid incoming value for property 'value' of class
'qx.ui.form.RadioButton': Expected value to be a boolean but found XXXX
The new selection API makes them much harder to use and a lot less
intuitive.
The Radiobutton Demos show using the Label for a value, but this is less
than optimal for translated applications.
Given the following:
var bnt1 = new qx.ui.form.RadioButton(this.tr("Green"));
var bnt2 = new qx.ui.form.RadioButton(this.tr("Blue"));
var colorGroup = new qx.ui.form.RadioGroup(btn1, btn2);
this.colorGroup.addListener("changeSelection", this.onChangeColor, this);
...
onChangeType : function(event) {
var value = event.getData()[0].getLabel();
if (value == this.tr("Green")) {
//This does not work - probably because it is comparing localized string
objects - not string characters
alert("You are looking at the grass");
}
else {
alert("You are looking at the sky");
}
++++
I can do the following
onChangeType : function(event) {
var value = event.getData()[0].getLabel().toString();
if (value == this.tr("Green").toString()) {
alert("You are looking at the grass");
}
else {
alert("You are looking at the sky");
}
++++
But it would be much simpler and more intuitive to allow user defined
values.
var bnt1 = new qx.ui.form.RadioButton(this.tr("Green"));
btn1.setUserValue("green");
var bnt2 = new qx.ui.form.RadioButton(this.tr("Blue"));
btn2.setUserValue("blue");
var colorGroup = new qx.ui.form.RadioGroup(btn1, btn2);
this.colorGroup.addListener("changeSelection", this.onChangeColor, this);
...
onChangeType : function(event) {
var value = event.getData()[0].getUserValue();
if (value == "green")) {
alert("You are looking at the grass");
}
else {
alert("You are looking at the sky");
}
The previous approach (pre 0.8.3) was much more intuitive where the
RadioButton had a label and a user defined value.
