You can show a black and opaque dialog. Save the attached file to
$FG_ROOT/Nasal/ and call it from any Nasal context, for example:
<key n="96">
<name>Backtick</name>
<desc>Toggle blackout.</desc>
<binding>
<command>nasal</command>
<script>black.beauty()</script>
</binding>
</key>
m.
dialog = nil;
beauty = func {
name = "boohoo";
if (dialog != nil) {
fgcommand("dialog-close", props.Node.new({ "dialog-name" : name
}));
dialog = nil;
return;
}
dialog = gui.Widget.new();
dialog.set("name", name);
dialog.set("width", props.globals.getNode("/sim/startup/xsize"));
dialog.set("height", props.globals.getNode("/sim/startup/ysize"));
color = dialog.prop().getNode("color", 1);
color.getNode("red", 1).setValue(0);
color.getNode("green", 1).setValue(0);
color.getNode("blue", 1).setValue(0);
color.getNode("alpha", 1).setValue(1);
fgcommand("dialog-new", dialog.prop());
gui.showDialog(name);
}
