I recently did some testing with trees in Web Dynpro...
...and encountered some problems.
What I want to do is simulating some kind of context menu in a tree structure
to enable the user to trigger actions like "Detail-view (for a leaf)", "Add new node"
or "Delete current node". Is there a UI element that can be used to do this?
Because I didn't find such a popup (or equivalent element), I tried to simulate
it otherwise: In this second scenario I wanted to use the mouse-click of the
user to select an entry in the tree. The different actions would be triggered by
clicking on additional buttons on the screen (one button per action).
Here I encountered the problem, that the selection in the tree is displayed
only by a (nearly invisible) border around this element. Is there a different
way to modify the appearance of a node in a tree (ie. make the text bold)?
Moreover I wanted to have icons displayed in the tree. I therefore specified
file://doc.ico as IconSource for my nodes (TreeItemType) with no effect
(except the error-msg: IconSource is not implemented on CSF_WDTreeItemType: LDCN.TreeView.level1). What / where do I have to specify / implement
the icon source?
When specifying the same URL as defaultIconItemSource at root-level
there are at least placeholders (with red cross) showing that there is some
icon which cannot be displayed. In this case there is no error-msg.
(doc.ico is available under mime...).
My system specs are:
Version: Sneak Preview 2.0.0
Build id: 20030515144
I would be pleased if someone could give me some hints... ;o)
