Hi Martin and many thanks for your reply! It took me a while before I noticed
it, better late than never though :).
I gave up the idee of using the Gallery as a source of inspiration. Instead
I've been taken a look at the following classes:
qx.ui.form.List
qx.ui.form.ListItem
qx.data.controller.List
...and renamed it to Desktop instead of Gallery.
The tree controllers store is bound to the new controller through:
treeController.bind("selection[0].folders", desktopController, "model");
The results of my effort can be seen http://www.trawiki.net/UMC/build/ here
.
To mark the items as selected in the right pane I made a new Appearence I
named "desktopitem". Is this the correct way to go?
I want the tree root content to be initially loaded into the right pane. I
tried this, but with no result:
store.addListener("loaded", function(ev) {
tree.getRoot().setOpen(true);
tree.addToSelection(tree.getRoot());
treeController.bind("selection[0].folders", desktopController, "model");
}, this);
I want the user to be able to navigate through all the arrow keys, not just
left/right. Any Ideas?
I guess it must have something to do with:
orientation :
{
check : ["horizontal", "vertical"],
init : "horizontal",
apply : "_applyOrientation"
},
...
...
_applyOrientation : function(value, old)
{
// Configure spacing
this._applySpacing(this.getSpacing());
},
...I would like to use "both" ;).
And, my last question (for now). Is it possible to mark a folder as "leaf"
in the model?
I do not want the deepest level to be visible in the tree if it is "files"
and not "folders".
In other words: Automobil.se -> Subfolder 1 (leaf).
...but still, the content inside of subfolder 1 will be rendered in the
desktop container (right pane).
grateful for any feedback I can get!
Best regards
Rickard
