resizing views programatically

How do I resize a view programmatically?  I have tried a few variations such
as setting the extent, & using show, invalidating the rectangle, but so far
have not come across the one that works.  Note that the views I am trying to
resize are typically in container views.
--thanks in advance

hmmm... if your containers have layout managers,
you might consult with them for resizing the views,
as they are the ones that are responsible for placement
issues. mostly.

what kind of layout do you have? The subview-tree (lower left
corner of view editor) and a listing of the layoutmanagers in use
would be helpful here.

shhhh ... I can't hear my code!

My first attempt was to look at how the splitter resized the 2 views.  I
then figured out how to access the views it was using & called the
proportional layout managers #reposition:to: method.  But this had no
effect, although curiously looking at the normal execution of the method, vs
my call to it, all the values seem to be the same.  So it may have something
to do with the windows calls higher in the stack.

I then decided to use the 'miss' method (make it simpler, stupid), and
simply tried to resize a button in one of the container views.  From what I
can tell the container view should not have impacted any of the methods I
was using, and as I had an inspecton on the button itself, there was no
question of the methods ending up at the right receiver.  So after trying a
number of experiments unsuccessfully, I figured that someone in the group
probably already had the answer.

still clueless in colorado

Gary,

Using a ClassBrowser as an example. Evaluate a line at a time.

Show a CHB
c := ClassBrowserShell show.

Resize it's classes (top left tree) view. Nothing happens visually.
(c view viewNamed: 'classes') arrangement: 2.

Force a redraw of the whole view. View updated.
c view invalidate

So if the parent view has a LayoutManager you change the arrangement aspect
of your sub view and then get everything redrawn

Buttons should be resizable if there is no LayoutManager involved. Evaluate
the first three lines to create a Shell with a PushButton ...

s := Shell show.
s view addSubView: (p := PushButton new).
p position: 100@100.

... then resize it

p extent: 10@10

Regards

It's still not clear what you are trying to do. If you have views that are
under the control of a layout manager (i.e. the are the children of a
container with a non-nil layout manager) then you shouldn't be trying to
resize them manually. Try this in a workspace:

parent := ShellView new show.
button := parent addSubView: PushButton new.
button position: 50@50.
button extent: 100@100.

Now what could be simpler than that!

Are you trying too hard?

If they are not in a container view, then it works just as you have shown
below.  What I was after was having a couple of toggle buttons that would
either maximize or mininimize a grid view, and a text view, along with using
a splitter between the 2.  But its not absolutely necessary, and now I know
why I have not seen this before!
Thanks for the input,

Maybe the package http://xss.de/dolphin/MaximizingEditor.pac gets you started.

btw: do we have some central place for putting up code snippets?
