wnck_screen_get_default() in panel plugin

[Dani]

Hi Simon,

First, very thanks!

I agree, it's a better feature for a standalone application.



I would love to know how to make standalone applications but my 
knowledge in this field are not what I would like.

I currently use brigtside, which is very old and disappears in debian 
buster ... it has gnomeui dependencies.

My idea is to migrate to gtk3 also brigtside, precisely from what you 
comment (standalone app), i'm trying it harder without help i don't know 
if i will get it.


The problem line is in hotcorner.c
line 771
WnckScreen *screenwnck = wnck_screen_get_default ();


For test
$ git clone https://github.com/damufo/xfce4-hotcorner-plugin.git
$ cd xfce4-hotcorner-plugin
$ cmake -DCMAKE_INSTALL_PREFIX=/usr .
$ sudo make install

then I should appear to add to the panel but before adding it, I open a 
terminal and put:
$ xfce4-panel -q
$ PANEL_DEBUG = 1 xfce4-panel

and this is when I add the hotcorner-plugin to the panel.

Very thanks!!
