[Cuis-dev] For the Cuis Cookbook

[H. Hirzel]

Hi Ken

I have realized that the construction you used in the recipe

https://github.com/DrCuis/Workbench/blob/main/Morphic/How_to_create_screenshots.md

is very compact. In particular

|clickArea (which is a BorderedBoxMorph object) has a property ||#'mouseButton1Up:localPosition:' which is set to a code block. |
|setProperty: #handlesMouseDown: toValue: true; is necessary to activate 
this behavior. If you put mouseButton1Up:localPosition: into a 
workspace, put the cursor in it and hit CMD-M. You get a list of morphs 
which implement this and indeed class morph uses this property 
mouseButton1Up: aMouseButtonEvent localPosition: localEventPosition 
"Handle a mouse button 1 up event. This message will only be sent to 
Morphs that answer true to #handlesMouseDown:" "Allow instances to 
dynamically use properties for handling common events." self 
valueOfProperty: #'mouseButton1Up:localPosition:' ifPresentDo: [ 
:handler | handler value: aMouseButtonEvent value: localEventPosition ] |

So the whole code is a nice example of getting instance specific behavior.

I think this should be captured in a notes or remarks section in the 
recipe for the cookbook.

Not sure how the note/remark should look exactly.

And when the recipe is finished we need to move it to a folder in

https://github.com/DrCuis/How-to-guides

either into an existing folder or a new one.

And the entry

https://github.com/DrCuis/Workbench/blob/main/Morphic/How_to_create_screenshots.md

deleted.

This does not need to be done immediately ; this is why there is a 
workbench repository.
