Re: [ve-dev] Create Visual Class Wizard - new design for review
|
Yes. I
think we should set the height of the tree listbox so that it fits the
three default styles (SWT, Swing, and AWT) without scrolling.
Ideally we would
want to expand all by default. This would work fine with the 3 default
styles (since it's a small set). However, it the set is augmented
with other styles, this would result in a large tree that would force a
scroll bar by default. Since we want to avoid scrolling as much as
possible, I would recommend expanding by default the first style in the
list (SWT) and collapsing the rest.
So ideally then, the Visual Editor - as downloaded from eclipse.org -
would only support these three on default (or whatever is deemed
appropriate by the Visual Editor team). We provide the contribution
interface, and if someone wrote a contribution to one of these styles
(say for example a company, if they released their own eclipse brand),
they would add it after the fact? I like the idea of expanding one node
on open, and leaving the other closed. I guess that pretty much solves
the scrolling issue.
2) If the list size is larger than the treeview, a vertical scrollbar
will be appended to the right side of the treeview?
<LS>
Yes. I
think we want to minimize the likelihood of a scroll bars since it will
eat into the available width.
</LS>
Ok. Sound sensible. So if they do go ahead and open all nodes, a
scrollbar would appear there.
3) Will there be, or does there need to be, further nesting in the tree
view, other than the single level we have now?
(ie we have SWT->Composite, will there be
SWT->FOO->BAR->Control)
<LS>
My assumption
was that there wouldn't be additional nesting. I set up the width
to accommodate just one level. Further levels would lead to a
horizontal
scrollbar (which I think want to avoid)
</LS>
I'm not sure if there would be or not either. If it would be
explicitly disallowed or not. Is there a use case for having multiple
nesting?
4) How will we control the extent of horizontal dimension of the
treeview? (Add a horizontal scrollbar or limits size of entries)?
<LS>
If possible, I wouldn't
display the horizontal bar until the width of the entries force
scrolling.
We should try to set the width of the treelist box so that there
is no horizontal scrolling with the default set of styles (with some
room
for string expansion in translation).
</LS>
I think the treeview is a good idea, though I do understand the
concerns it might not be ideal. It does allow for expansion beyond the
current static ui, and if the list of styles did get rather long the
treeview can compensate with scrolling within the pane, even if that is
not desirable. It does break the flow a bit (the top part of the class
is top->bottom flow, the bottom half (the treeview and options) is
left->right flow) but thats kind of minor, and nothing too bad.

Very nicely done!
Some minor questions:
1) On the treeview, will all the elements be automatically expanded as
shown in the screenshot?
2) If the list size is larger than the treeview, a vertical scrollbar
will be appended to the right side of the treeview?
3) Will there be, or does there need to be, further nesting in the tree
view, other than the the single level we have now?
(ie we have SWT->Composite, will there be
SWT->FOO->BAR->Control)
4) How will we control the extent of horizontal dimension of the
treeview? (Add a horizontal scrollbar or limits size of entries)?
