Is there a way to use Keybuf with default widgets like Edit or know the cursor position?

[leelavg]

I have a functionality with each keypress the line in Edit is autocompleted based on the existing history, however due to unavailability of key-press events on Multiline or Single Edit I'm not able to determine the position when the user input is ended.

Are there any plans for supporting Keybuf other than for View? (or) possible to know the cursor position in the Widget (will be much more helpful)?

Simplifying further, for immediate issue (ultimately keybuf as I need to capture more than printable chars), is it possible to know the last position in the Edit?

I tried to isolate the requirement as below (at the end I wanted to store cd support/ but can't since the cursor position isn't available unlike from OnFilter), let me know if more info is required, thanks!

Hi! The easy way to know the cursor position when the input in EditBox has finished, is to use the cpos field in EvText struct of edit_OnChange() event. At the moment, this field is set to UINT32_MAX, but can be implemented easily.

Yes, I saw that it only sets text, I'm trying a lot to refrain from hacking through the sdk even though it's quite understandable for a beginner like me it takes away the little time I get to develop my app 😅.

Do you've any pointers on how this can be done, I remember (after looking at code) it isn't straightforward (for me) and can give a try based on some guidance.

I'll try to upload a patch this week that fixes this as well.

Since the main requirement is met I'm closing the discussion, as Keybuf isn't the correct tool, will raise a separate issue/discussion when required.
