All,
I'm trying implement a complicated inmethod DataGrid table and I would
like a sanity check as to the solution I came up with. The table is
multiple selectable, but in the case of the "name" column, I want to
have a hyperlink that forwards the user to a new view. In the case of
other columns I want the DataGrid to perform it's multiple selection as
normal.
The problem is that DataGrid's as far as I can see, only allows text
output for each cell, and don't allow you to render a new component such
as a panel or a link with a label.
I've attempted to intercept "cellClicked" method, but attempting to
redirect to a new view within that method causes a error in wicket.
I've thought about overriding "public Component newCell", but that never
gets called, and the IRenderable version of newCell isn't any use.
I've also tried to wrap WicketColumnAdapter and then use a standard
wicket PropertyColumn and the populateItem method to create a link with
a label, but as expected this fails as per the advice given in the
WicketColumnAdapter javadoc.
I've come up with this solution, but it seems like a horrific hack, and
I wonder if there isn't a better way of doing it, that makes more sense.
In all honesty, I totally chanced upon this solution;
columns.add(
new WicketColumnAdapter( "displayName",
new
org.apache.wicket.extensions.markup.html.repeater.data.table.PropertyCol
umn(
new Model<String>("name"), "surname", "
displayName" ) ) {
@Override
public Component newCell(WebMarkupContainer parent, String
componentId, IModel rowModel) {
Object object = rowModel.getObject();
LinkPanel panel = new LinkPanel( componentId,
object );
return panel;
}
}
);
By wrapping a Wicket PropertyColumn in a WicketColumnAdaptor, the
newCell method on the adaptor gets called, and hence we can populate the
component.
Cheers,
Col.
