Feature: save and restore edit point #35

Open quozl opened 5 years ago

At the moment, the edit point is always set to the start of document.

It is common for word processor programs to open a document and position the edit point to the most recent edit point. We might do the same.

[ ] how common is this? Survey existing word processor programs and assess,
[ ] gather user experience opinions,
[ ] save the edit point with the document, restore on resume, yet continue to accept documents that do not have the saved edit point.

@quozl I looked through all the functions of Abi.Widget from here, but did not find any methods suitable to store the last edit position. However, would it be a good feature to store the last edited page number in the document and restore the same page on opening the activity again?

Thanks!

Thanks, but no. Save and restore edit point position to the exact letter, not the page,

you're jumping ahead, there are other development tasks in this issue to be done first,
there are hundreds of AbiWord functions available behind the the invoke and _invokeex methods; search the source code of the Write activity for those that are used now, and read the source code of AbiWord to see the functions we are not using yet,
when collaborating, the edit position of the other user is shown (using a caret cursor), so it should be possible to obtain it by some means; AbiCollab_Import.cpp mentions a data type PT_DocPosition, and functions getEndOfDoc and getPos.

@quozl Thanks I shall look into the methods you've mentioned above. I wasn't aware of _invoke and invokeex methods of AbiWidget before
