Hello,
Inside the Palette there is a Recorder<T> which is basically a
customized HiddenField that holds the id of each selected element.
/**
* Returns recorder component. Recorder component is a form
component used to track the
* selection of the palette. It receives <code>onchange</code>
javascript event whenever a
* change in selection occurs.
*
* @return recorder component
*/
public final Recorder<T> getRecorderComponent()
{
return recorderComponent;
}
So myPalette.getRecorderComponent().add(new
FormComponentUpdatingBehavior("onchange"){
protected void onUpdate(AjaxRequestTarget
target) {
/**
I imagine something like this should do
the trick, but i can't find anything like it:
Media m = getSelectedItem();
imgPanel.setFilname(m.getFileName());
*/
Iterator selectedChoices =
myPalette.getSelectedChoices();
// let the image panel do something with
the selected choices.
target.addComponent(imgPanel);
});
This should give you what you want.
Regards,
Mike
i have some trouble to access the currently selected item of a Palette
component. By selected i mean the item which is highlighted if a user
clicks on any of the items within the palette. i need that access
because i want to update an Image component which renders an image
which reflects the selected item
here is the (simplified) piece of code i use to get notified if the
palette is clicked:
final Palette palette = new Palette("palette", mediaModel,
paletteModel , renderer, 10, true) {
private static final long serialVersionUID =
-5683120408447757525L;
@Override
protected void onBeforeRender() {
super.onBeforeRender();
getChoicesComponent().add(new
AjaxFormComponentUpdatingBehavior("onclick") {
private static final long serialVersionUID =
-6216894553871444828L;
@Override
protected void onUpdate(AjaxRequestTarget
target) {
/**
I imagine something like this should do
the trick, but i can't find anything like it:
Media m = getSelectedItem();
imgPanel.setFilname(m.getFileName());
*/
target.addComponent(imgPanel);
}
});
}
};
