Where to call Qt Extcap dialog

[Roland Knall <rknall () gmail com>]

Hi

I am currently implementing a Qt Dialog for the extcap interfaces. The
dialog part is rather simple and mostly tricky because of the different
kinds of interface options for extcap interfaces. But I ran into an issue,
which is irritating.

How should the extcap interface options be shown?

On Gtk, when you double-click on the interface in the interface list, the
capture options dialog opens. In Qt, if you do the same, the capture
starts. So, my next idea was a tab in the "Capture Interfaces -> Options"
dialog, which I threw out, because you could select more than one extcap
interface, which would result in the need of more than one tab-page. Also
you would have the whole issue of hiding the tab pages, and selecting the
extcap interface on a single extcap tab page (maybe via combobox) is not
very UI-friendly, because you would have selected the interfaces in the
first options page already.

So, for now, I've come up with the following solutions:

Add a new column in the "Capture Interfaces -> Options" dialog, which
includes a button a user can press to open the specific configuration
dialog for a specific extcap interface with a start button, to start the
capture immediately from the dialog.

Additionally, a Ctrl->Click on the interface in the main window list, would
open the same options dialog, with a start button to start the capture
immediately as well.

Is this solution plausible, or should there be another method? Because
otherwise, I would prepare a patch for the end of this week.

regards,
Roland
