Feature/click through

[mortoray]

adds --click-through to pass mouse input through the window
adds --keep-above to move window to top of others

[phillipberndt]

Thanks! As mentioned in the other thread, I'm not overly eager to add any X11-specifc features to pqiv, but I'll leave this PR open for others to find.

[hyperdoxical]

This is exactly what I wanted!

[Heath123]

It gives me this error:

/usr/bin/ld: pqiv.o: in function `window_configure_callback':
/home/heath/pqiv/pqiv.c:6641: undefined reference to `gdk_x11_window_get_xid'
collect2: error: ld returned 1 exit status
make: *** [GNUmakefile:170: pqiv] Error 1

[mortoray]

Try installing the x11 or gdk dev libraries (libgtk-dev perhaps). I'm not clear on which one it was, since I have so many installed on my machine.

[Heath123]

Installing libgtk-3-dev didn't work

[Heath123]

Do you have binaries maybe?

[mortoray]

I do have the binary I use. I used ldd on it and it lists these libraries:

[Heath123]

OK, mine seems to be using GTK2 instead of GTK3

[Heath123]

Forcing GTK3 seems to have fixed it

[Heath123]

Yay, it works, thanks for the help (I realised the GTK version was different from the libraries). I had to do ./configure --gtk-version=3

[Hello1024]

This branch has no support for Wayland. Neither the click through nor the keep above features seem to work correctly.

(pqiv:374267): Gdk-WARNING **: 16:45:06.250: ../../../../../gdk/x11/gdkwindow-x11.c:5650 drawable is not a native X11 window
Segmentation fault (core dumped)

It can be worked around by setting an environment variable like this:

GDK_BACKEND=x11 pqiv --click-through --transparent-background --hide-info-box --keep-above  alphatest.png 

Although then the click-through support behaves... oddly... Sometimes a click will go through multiple windows and end up clicking some background window. I suspect it's some XWayland bug.

[parkerlreed]

Tried this out but unfortunately seems to fail compiling at the libav step.

Got this working by ignoring libav!
