Normally qooxdoo uses selection managers for this things.
This means "getManager" on your gallery instance should give
you the selection manager. Then you can use getSelectedItems
to get a list of selected elements.
D'oh! I should have guessed this from the ListView example.
As it turns out, getting the selectedItem from the SelectionManager
of a Gallery is not all that interesting -- it is a DIV object.
So here's a quick rundown of how I work with the selection:
- when you build your array to initialize the gallery, keep a
reference to this array
- when you want to get the selected image out of the gallery,
do this:
var mgr = gal.getManager();
var browseimgs = mgr.getItems();
for (i = 0; i < browseimgs.length; i++)
{
var itm = browseimgs[i];
if (mgr.getItemSelected(itm))
{
selected_image = gallery_images[i];
}
}
(this assumes that the QxGallery is in a variable "gal", and the
array used to initialize gal is "gallery_images")
Follow-up question: how can you add or remove images from a gallery
or a gallery list? My current solution involves building a new gallery,
but that seems horribly inefficient.
Take a look at the "update" methods of QxGallery. If you think there is
missing something or you need some more features please feel free to
submit patches to this list.
