Getting Scintilla Aucomplete Box Width

[Stefano Mtangoo]

I wonder if there is a way to get current Scintilla AC Box width, after
Autocomplete List is loaded.
I modified sources to add function to emit a signal when Autocomplete
selected Item changes and have a need to know the width.
Also if you are interested in new signal I can provide a patch

TIA,
Stefano

Scintilla does not expose an API to retrieve this information.

Its likely the information can be derived using platform calls. The list will be a window and platforms provide calls to retrieve their positions such as the win32 call GetClientRect as used by the platform interface method GetClientPosition.

Between core Scintilla and the platforms is a 'platform interface' which is supposed to remain stable. Its likely that adding a new signal will require updating this interface, breaking current implementations. Implementations of the signal would (eventually) be required for all platforms. There may even be problems with implementing this on some platforms.

Its worthwhile publishing a patch but adding this to Scintilla will require some person or group to design and implement a cross platform API along with platform-specific implementations.

Is it possible to get this information in ScintillaBase? If yes any
direction?
Am new to Scintilla internals and I get a bit of problems in understanding
some issues!

I see. Its useless anyway apart from my personal uses :)

You should step through the display of an autocompletion box in a debugger or by reading the code.

Its likely other people will want item selection notifications but if they do, they should now be volunteering to help implement it.
