Re: [cdt-debug-dev] CDT debugger features

[Gregery G Adair <gadair@xxxxxxxxxx>]

Is anybody working on this?  It sounds
like this would allow me to view the contents of an icu4c UnicodeString
in the debugger, which would be extremely valueable for myself and several
over developers in the office.  

thank you,

Samantha,

Ah, ok. Great. So the client can both provide specialized rendering and
the UI mechanism that allows the user to switch to that rendering. Thanks
for the details. I'm sure they'll save us some time when we implement this.

John -

I think this is achievable in the CDT layer. CDT can provide a custom 
text 
rendering by extending AbstractTextRendering.
This rendering takes a 
code 
page when it is constructed. It also has
an API to allow clients to 
change 
its code page after it is created.

In addition, CDT can contribute actions to this custom text rendering 
via 
object contrbution.  CDT can contribute
an action that allows user to
switch between the different display modes on the fly.  When the user

has 
switched to a different display mode, the
action could change the code 
page 
on the custom text rendering. Finally, the
action would have to tell 
the 
rendering to update by calling AbstractTableRendering#updateLabel().

This 
would not cause the rendering to reget its
content. It simply 
re-renders 
its current content.

Thanks..

Samantha,

One thing that occurs to me. While the physical rendering of the bytes

in 
the Memory View as UNICODE (rather
than ASCII) is doable from the CDT
layer, we would nonetheless need to give the user the ability to switch

to 
this display mode. In other words, the Memory
view doesn't know whether 
a 
block of memory represents UNICODE or not.
It's up to the user to tell 
the 
Memory view to switch to this alternate
rendering mode. So, unless the
client layer (CDT) can add this UI switch to the view, this feature

still 
implies some work at the platform level,
no?

John
