Programatically insert text at cursor position in TextView

[leelavg]

I misunderstood the docs If start == end the caret is moved to the position, deselecting all text. and spent a good amount of time assuming my app has an issue only to realize the feature of inserting at cursor doesn't exist after looking at the implementation. (I'm on gtk and mostly the implementation is same for other platforms)

Reproducer:

1. After cut, move cursor to position 10 <-- works
2. At position 10, string something should be printed <-- doesn't work (I suppose the feature doesn't exist? something like, `textview_printf_at_cursor?)

I'm loosing implementing this and I've worked out most of the pieces.

I can duplicate this into a issue if required, pls let me know, thanks!

Maybe tableview is better suited for my usecase (there is a overhead though), I'll change to it if textview will not provide the feature.

Hi @leelavg!
Indeed, textview_writef() and textview_printf() add the text to the end of the control. I'm sorry the documentation isn't explicit about this. As you say, the best solution is to add textview_writef_at_cursor() and textview_printf_at_cursor() to avoid breaking the current operation. Please open a ticket in the issue section so other users can be aware. It doesn't seem complicated to implement.
