That appears to not be possible with simple property settings. Maybe there
should be a selectionMode:"none" but there isn't.
The code I reviewed to find a possible answer were qx.ui.form.List, which
includes qx.ui.core.MMultiSelectionHandling which creates a selection
manager based on this.SELECTION_MANAGER. Since MMultiSelectionHandling is a
mixin, 'this' refers to the object of the class that included the mixin,
which was List. List does, in fact, define SELECTION_MANAGER to be
qx.ui.core.selection.ScrollArea. The ScrollArea manager has an _isSelectable
method that could be overridden.
So one way to accomplish what you're after seems to be to extend
qx.ui.core.selection.ScrollArea to, for example,
custom.MySelectionScrollArea and override the _isSelectable method. It
doesn't appear that instantiating a list does anything with a selection
manager, so you can probably simply instantiate your list: var list = new
qx.ui.form.List(); and then set the selection manager to be your selection
subclass: list.SELECTION_MANAGER = custom.MySelectionScrollArea;
I never tried this, but hopefully it'll work for you, or put you on a path
towards something that works.
You might post an enhancement bug to bugzilla requesting a
selectionMode:"none". Then again, there may be an easier way to do what
you're looking for that I didn't come across in my research. If so, someone
will point it out.
