Stupid Question

I am exploring Morphs and I tried the following code:

|sm ws|
    ws := WideString new: 5.
    ws wordAt: 1 put: 16r2264.
    ws wordAt: 2 put: 16r22C5.
    ws wordAt: 3 put: 16r2211.
    ws wordAt: 4 put: 16r2219.
    ws wordAt: 5 put: 16r221A.
    sm := SimpleSwitchMorph new.
    sm label: ws font: (LogicalFont familyName: 'Cambria Math' pointSize: 15).
    sm openInWorld.

Now in the upper left corner of the World screen I have a button that shows the math symbols, LTE, dot, Summation, large-dot and SQRT, and will change backcolor from gray to light-red. Exactly what I wanted; however, how do I get rid of the morph? The class documentation is full of examples of this kind so there must be a way to clean up the World as It persists through a quit and save and then open.

Thanks.

Re: Stupid Question

Bring the halo menu.
In Windows: Alt+Shift+Left click over the morph

Hello,

On Mac, I press Cmd + shift + mouse click and while keeping all these pressed I move the mouse, and it automatically create a rectangle selecting all the morphs inside. It allows to select multiple morphs which is much better in some cases.

There's also a setting (search for "easy selection") which let's you just click and drag, without the game of Twister [1] ;)

Alt-Shift-Left click does indeed initiate the halo under Windows.

But...

In my testing, I used AthensDemoMorph new openInWorld

When I use the Move element of the halo, I get "MessageNotUnderstood: AthensDemoMorph>>passenger"

I'm a novice, but that seems unusual.

Athens is a work in progress… that is a bug

Re: Stupid Question

The halo works on morphs. If you have an athens surface which is not in a morph, the halo does not work.

Anyway this is a bug.
