Okay, there is at least one more fallacy. If I add a method like the
following to the DateWrapper to increase the date by x days, the
label-binding wouldn't call the converter because the wrong key is listened.
But if I am setting the binding-key to gameData.date.date, the converter
would run but fail because the data-value is the date-property itself which
has no getFormattedDate-function...
The changed DateWrapper-class for completeness:
qx.Class.define("mkss.data.DateWrapper", {
extend: qx.core.Object,
properties: {
date: {
check: "Date",
event: "changeDate"
}
},
construct: function (date, format) {
this.base(arguments);
this.setDate(date);
this.dateFormat = new qx.util.format.DateFormat(format);
this._intDateFormat = new qx.util.format.DateFormat("yyyy-MM-dd");
},
members: {
getFormattedDate: function () {
return this.dateFormat.format(this.getDate());
},
addDays: function (incDays) {
// found here: http://jsfiddle.net/sparebytes/XrWzq/
var tmpDate = new Date(this.getDate());
tmpDate.setDate(this.getDate().getDate() + incDays);
this.setDate(tmpDate);
}
}
});
