I'm working on Vattery, a battery meter for the systray, which is written in Vala. It seems that the Double class in Vala lacks a to_int() method, so to cast a double to an int I've been using Double.to_string().to_int(). Surely there's a better way? The Vala reference manual is woefully incomplete.

Perhaps this is a dumb suggestion, but won't a caste do it?

a = (int) b;

...or, doesn't casting extend to this type of conversion?

Maybe you can help me with another Vala problem.

When I compile with Vala I get this error:
Code:

/root/vattery/vattery-retro-jemimah-patches/main.vala:309: undefined reference to `gtk_status_icon_set_tooltip_text'


The correct code for our version of Gtk is 'gtk_status_icon_set_tooltip'. I've been killing the build script halfway though so I can fix the generated C code, and then finishing the build by hand.

Is there a permanent way to fix this?

Heh heh, no that was just a lucky stab at it the last time. I wouldn't have a clue how to fix that gtk problem!
