Create a custom checkbox component
Hi!
I need to display a checkbox in a webpage. This checkbox work as a node
in a treeview, so i need to save in the checkbox tag which node is his
parent and which node are his children.
I tried to simply add two attributes to the checkbox tag like this
<input id="test" type="checkbox" parent="parent" children="children" />
it works just fine in I.E but firefox doesn't recognize the parent and
children attributes, thats why i'm trying to solve this creating a
component that has those attributes.
I'm a beginner using tapestry so i'm clueless about how to create a
component that works the this way.
Can any one send me some material or explain me how to create this
component?
Thanks in advance

Yes, there's a "value" parameter you can bind some page method to so
that you can easily get/set the !Object in the hidden field from the
page (you'll have to cast the object obviously).
I think you'll have all your checkboxes inside a For component so I
guess you'll iterate over a collection and have something like
<component id="userList" type="For">
<binding name="source" value="nodes"/>
<binding name="value" value="currentNode"/>
</component>
<component id="nodeCheckBox" type="Checkbox">
<binding name="value" value="currentNode.selected"/>
</component>
<component id="nodeParent" type="Hidden">
<binding name="value" value="currentNode.parent"/>
</component>
<component id="nodeChild" type="Hidden">
<binding name="value" value="currentNode.child"/>
</component>
Well I think guessed too much but as you haven't provided much information :-)
Depending on your model and on what you have to achieve things could
be even simpler as maybe you already have parent/child informations in
node itself

I like the idea!!
But when the browser render this component will I be able to access
those attributes?

I think you could just make a component using a normal checkbox PLUS
two Hidden components (
http://tapestry.apache.org/tapestry4.1/components/form/hidden.html)
containing the parent/child references.
Just extend BaseComponent and use one Checkbox plus two Hidden in your
new component.
Adding strange, non standard, attributes to tags your browsers will
see is never a good idea :-)
