[TSF-IME] Page size

Question

Hi,
i got a question about Text Service Framework, the pages /pagesize and selection index.

Do i understand it right that based the the selected candidate the page is set ?
Is there a way to get all candidates of the currentpage and/or set a different size of a page ?
Or simply disabling the pageing so i retrieve just all candidates and handle the stuff myself ?

Also is there a limit of retriving candidates ?
With https://learn.microsoft.com/en-us/windows/win32/api/msctf/nf-msctf-itfcandidatelistuielement-getcount i get a count if over 1000
but iterating over https://learn.microsoft.com/en-us/windows/win32/api/msctf/nf-msctf-itfcandidatelistuielement-getstring
retrieves always just 100

Hello,

Is there a way to get all candidates of the currentpage and/or set a different size of a page ?

ITfDocumentMgr interface seems what you are looking for. Through it you can get ITfContextView interface which implements ITfContextView::GetWnd function. Through the window handle you can do what you want to do.

Or simply disabling the pageing so i retrieve just all candidates and handle the stuff myself ?

Refer to TextInputCtrl.cpp for how to manage the window by yourself.

Also is there a limit of retriving candidates ?

The behavior of candidate list UI can be controlled by the application like this: limit the candidate list count to MAX_CAND_STR 50. So for getting all candidates you can try ITfCandidateList::GetCandidateNum.

Thank you!
