[zathura] Float selection

[Igor Almeida]

Hi,

I'd like to implement a 'float selection' functionality, to be able
to extract some selected region (maybe with right-click, to distinguish
from current behavior?) to a separate window.
This would be useful for keeping a diagram visible while I read its
description along the original document's text, for example. With a long
enough text, eventually you need to scroll and lose sight of what the
document is referring to.

Can anyone offer hints as to how I could implement that with zathura?

Today, I can mimic that by opening a second instance and shrinking the
window to fit only what I want to see, which is far from ideal.

I'm not really sure if this needs to be specific to the PDF plugin, but
that's my main goal for now.

Any help is appreciated.

So, there is already code to store the text of a selected area in the
clipboard. I think you can adapt the code to just copy parts of the
rendered image instead of the text.

See page-widget.c for details. In particular
cb_zathura_page_widget_button_release_event.

Let me know if you need more info.
