I have installed glade in linux mint 18 and 17.1, and in both versions I have the same problem. Glade doesn't seem to recognize the '.' as the separator for the decimal part; it recognizes the ',' character.
Since I am in Spain, I am working with the Spanish keyboard layout, but I have setup the OS so that the numerical format recognizes '.' as the decimal separator character. Other applications, such as OpenOffice, work fine and recognize the '.' character.
This is a problem when I load the example.tch file that comes with glade because any of the numerical values inside the file is properly read.
Does anyone has a similar problem? Is this configurable in any way from glade?
Thanks and regards
