问题
After having a look at firefox's history window, i saw something which i want to implement to my own entry:
How can I make the default text in the entry faded like that?
回答1:
In GTK+ it's called placeholder text, available in GtkEntry since GTK+ 3.2.
回答2:
Here's an implementation for GTK versions earlier than 3.2:
