Hi!
I am really enjoin using of UIBinder! But still some of my code looks
a bit strange and unpleasant in comparison with what I would like to
see... I'll explain in details:
Imagine I have a UIBinder component with some Label inside:
...
<g:Label ui:field="label">
...
In that case I can set a value to this label in java code like this:
@UiField
Label l;
...
l.setText("....");
...
Imagine I want to bind this panel to some object. As a result if this
data object has a lot of properties I end up with huge list of
@UiField declarations and setText methods, and after a while it get's
really hard to find out what property where should be displayed.
I would another approach that allows me to bind to some properties
inside the UI directly:
<ui:with field='dataContext' type='com.toi.client.DataObject'/>
...
<g:Label text={dataContext.getValue}>
Now this code looks already better, because now I can clearly see
where and what properties are displayed. I also don't need so many
setText methods in java class any more... But this approach solves
only one problem - bind UI to data object when UI control is
created...
What else do I need from it?
1. First, I would like to have a refresh method, so when I want to
display another object in the same control I will simple use
this.dataObject = newDataObject; refreshUI(); and trigger all
connected labels, textboxes etc. to call setText and other methods
again (In that case I won't need to re-create UI when new object comes
- only reloaded properties...)
2. Second. I also would like to have bi-directional link. Which means
- if I say <g:TextBox text={dataContext.Value}> not only text from
dataobject is loaded into textbox during initialization, BUT also data
object value is changed when somebody edits TextBox.
Maybe somebody could help me with this problem? Maybe somebody knows
some framework or workaround that could be used in that case?
Or maybe somebody could show me the way to somehow catch events from
my UIBinder object, so I can bind them manually to properties on base
class implementation?
Thanks!
Artem
