Code highlight

Hi everyione,

When one selects piece of code in any code editor pane, every other same
piece is highlighted with less bright color.
I'm using spec to build a UI and would like to know which event is
responsible for this highlihts.
For example, in TextModel there is one event that probably is related to my
problem, but I'm not sure: #whenReadSelectionIsChanged:
So, what I want is to use the event which is invoked when selection of code
is changed - probably it is the name of event :)

This is in TextMorphForEditView>>#selectionChanged.

Recognizing this change and searching/updating other selections are only
handled between the TextMorph and the Text Paragraph (Paragraph>>#displayExtraSelectionOn:)

I don't think Spec (or  the TextModel class) is aware of this property.

(The same for findAndReplace-search results).

I’m not sure that this is what you need, but have you tried changing the read selection block? ( TextModel>>readSelectionBlock: aBlock ) I would imagine that that is the block that is called when a selection is changed.

Ok, I see. That's not good, but thanks.

However, TextModel has selection as instance variable, so maybe I could implement event that I need?

I had a quick look. I confirm that TextModel keeps a value holder on the current selection interval, in the instance variable named ‘selection', but apparently there is no API to register to notifications to that. I consider that a missing feature, so I think it is best that you add a bug report for that.

Exactly! I think so too: it's just missing, and has to be fixed. I'll open an issue

Thanks

 

In the mean time, I’m sure you could hack something together that registers your application for notifications of the value holder that is in ‘selection’ ;-)

At least I can try to figure it out.
