|
|
Converts Glade files into XML files which can be loaded with GtkBuilder.
|
|
The [INPUT] file is
|
|
|
|
-w, --skip-windows Convert everything but GtkWindow subclasses.
|
|
-r, --root Convert only widget named root and its children
|
|
-h, --help display this help and exit
|
|
|
|
When OUTPUT is -, write to standard output.
