Hi Alexei,
Hello, List
Is there any way to access the qooxdoo widget somehow except the direct
approach (by name in the code)?
Here the example:
// Application main function
qx.Proto.main = function(e) {
var layout = new qx.ui.core.VerticalBoxLayout();
layout.addToDocument();
var btnTest = new qx.ui.form.Button("Test");
layout.add(btnTest);
}
Question:
Is there some call like this:
qx.core.some_ns.someGlobalCall()....
to access layout and btnTest?
I have written a simple widget registry mixin for the api viewer. this
mixin adds an 'id' property to each widget and a 'getWidgetById' method.
qx.Class.include(qx.ui.core.Widget, apiviewer.MWidgetRegistry);
...
var btn = new qx.ui.form.Button("OK");
btn.setId("okBtn");
...
var btn = this.getWidgetById("okBtn");
// or
var btn = apiviewer.MWidgetRegistry.getWidgetById("okBtn");
I think, it would be easy to implement something like this for your 0.6 app.
Best Fabian
qx.Mixin.define("apiviewer.MWidgetRegistry",
{
properties :
{
id : {
check : "String",
apply : "_applyId",
nullable : true,
init : null
}
},
members :
{
_applyId : function(id, oldId)
{
var statics = apiviewer.MWidgetRegistry;
if (oldId) {
statics.unregister(this, oldId);
}
if (id) {
statics.register(this, id);
}
},
getWidgetById : function(id)
{
return apiviewer.MWidgetRegistry.getWidgetById(id);
}
},
statics :
{
__objectDb : {},
/**
* Returns the widget registered under the given id by [EMAIL PROTECTED]
#register}
*
* @param id {String} the id of the widget
* @return {qx.ui.core.Widget} the widget.
*/
getWidgetById : function(id)
{
return this.__objectDb[id];
},
/**
* Registers a widget under the given widget id to be used with
* [EMAIL PROTECTED] #getWidgetById}.
*
* @param widget {qx.ui.core.Widget} the widget to register
* @param id {String} the id of the widget.
*/
register : function(object, id)
{
if (this.__objectDb[id]) {
throw new Error("An object with the id '"+id+"' already exists.");
}
this.__objectDb[id] = object;
},
unregister : function(object, id)
{
if (this.__objectDb[id] !== object) {
throw new Error("The object is not registered with the id '"+id+"'.");
}
delete(this.__objectDb[id]);
}
}
});
