Hi all,
sometimes it is useful to attach data to qooxdoo widgets which is not
represented by the native properties, for example in a tree, information
about the tree element owner, write protection, description of the tree
node, etc. etc. Now I can go ahead and attach any property I want to the
widget. But in order to prevent clashes with property names of future
versions of the widget, it would make sense to me to have a native
method getUserData() and setUserData() available in all widgets which
lets me store such data without worrying about conflicts.
This is super-easy and painless to implement, and I would like to
request to include it in the next release:
QxWidget.prototype.getUserData = function()
{
return this._userData;
}
QxWidget.prototype.setUserData = function(data)
{
this._userData = data;
}
Hi Christian,
I have just removed our old methods addData and removeData from QxObject
as they are far to complex. I have no added these methods to CVS which
should allow you to have a nice, fast interface to store some data to
your objects.
Compared to your solution, I found it useful to handle the different
fields inside the class.
proto.setUserData(vKey, vValue)
{
if (!this._userData) {
this._userData = {};
};
this._userData[vKey] = vValue;
};
proto.getUserData(vKey)
{
if (!this._userData) {
return null;
};
return this._userData[vKey];
};
You can now do a myTreeFolder.setUserData("readOnly", true);
Hope you like it.
Regards,
Sebastian
thank you.
Christian
