[Pharo Trick: #0006] - Run code from a button window

-----------------------------------------------------------------------------------
[Pharo Trick: #0006] - Run code from a standalone button window
-----------------------------------------------------------------------------------
Works in: Pharo 2.0, 3.0, ...

In Pharo there is a class called ButtonModel - it is a model used for buttons when
building UI's with the Spec framework. But it can be used also standalone
to open a button window with an action block:

|b|
b := ButtonModel new.
b openWithSpec;
label: 'Run my code';
action: [ Transcript open ]

So you just have to click to run some code.

[Pharo Trick: #0007] - Write UI prototype in a workspace

In Morphic, there is no way to quickly prototype a UI.

But in Spec there is a Dynamic class supporting this, so one can try different things

directly from a Workspace

An example:

m := DynamicComposableModel new.

m instantiateModels: #( button ButtonModel list ListModel).

m list items: #(1 2 3 4 5).

m button

label: 'Plip';

action: [ self halt ].

m openWithSpecLayout: (SpecLayout composed

newColumn: [: c | c add: #list ; add: #button height: 26 ];

yourself).
