Selection indicator in treeview

jjfabian — Thu, 08 Dec 2011 13:01:40 GMT

Hi everyone,

when showing a hierarchy as a treeview as a listbox, I am getting some unwanted behaviour.

When I select a node from my treeview, the selection indicator only appears on the right side of my listbox. This seems to be due to the fact, that QlikView is somehow aware of how many leaves or subnodes seem to be available.

If I click all the way through my treeview, seeing the actual fields is no problem.

For me this is no problem. However, my users which I'm building this App for don't always drill down to the actual field, usually only the top nodes are selected

(e.g. Node 1 as in my example).

Now the problem with that is, is as mentioned, the selction indicator. Due to the depth of my treeview, it is not clearly visible for those who don't know where to look for it.

Is there a way to make the indicator visible as suggested in my example, or is there another alternative?

Your help is very much appreciated,

Jakob

Any feedback? Alternate suggestions would also be appreciated.

I am not sure there is a way to actually move the green dot to the other side, but I find that the main issue here is that the green dot will not appear at all when using AJAX client when horizontal scroll bar exists. So you either need to size your list box width so that it is wide enough to handle the completely expanded list OR in the list box properties --> Presentation tab, select Suppress Horizontal Scroll Bar. Either of these methods will keep the green dot viewable to the end user.

Hi Aaron,

while suppresing the horizontal scrollbars kind of gives me what I want (seeing the green dots at any time), it is unsuitable for my specific example. The treeview that I'm displaying contains so much depth that suppressing the scrollbars makes it completely unusable.

The width isn't really an option either. Because of my treeview depth the listbox would just become huge...

Understood. So, it might be possible to create a trigger on the path field (field level triggers found in document settings) to select all the children when the parent is selected. This would result in the green selection bar all the way down rather than the green dot. But I have yet to get this to work effectively in an application (I was working on a similar tree view issue the other day). But it is an idea worth exploring. If anyone else has success getting this to work seamlessly, please jump in
