Can Lister-plugin catch File > Reload File event?

[little-brother]

I supposed that on F2 Lister recreates viewport by similar way when user switch from Nultimedia to Text view.
But it doesn't happen. Also I didn't find in a manual how to react on this. Is it possible?

What exactly do you mean by viewport? I only know viewport as a directive in html files

viewport = a window (form) to a file content in memory (an opened file).

Here the window of the Lister.
little-brother wants to enable F2 -support for his XML view plugin.

I open a XML file in xmltab, that file is modified in the meantime, I want to use F2 to reload the changed file on the fly...


I have heart about that while learning VIM , googling now I found this explanation:

Hmm, it seems to be a restriction of plugins when using the "4 Image/Multimedia" view. If I view an .rtf file using Listers build in function for that (*), then F2 does update the view when the file is changed externally, but not if I view the same file with a plugin.

(*) - Using Listers RTF view is shown in Listers menu as "4 Image/Multimedia"

However if I view an image (.bmp, .gif, .jpg, .png) in lister without using a plugin the F2 has no effect when changing the image externally.

Thanks for this research. Maybe it's a bug?
I can catch F2 and then call ListCloseWindow and ListLoad function to emulate Reload behaviour (it's not fine but should work).
But I also want to menu F2 will work.
P.S. This doesn't work because Lister window lost context (handle of child window).
