Support translatable strings for placeholder text in widgets
Last modified: 2014-04-26 03:52:40 UTC
If I have a gtk entry with placeholder text, there is no UI in Glade to mark it as translatable (and I'd say it should be translatable by default anyway). And if you hack the gtkbuilder xml file to force it: <property name="placeholder_text" translatable="yes">Search...</property> ...next time you open that file in Glade, it will just reset it to take out the ' translatable="yes"' part.
seems to work fine here, in a quick test with 3.18.1
