Current directory field cannot take input larger than field UI width

[Samuel Leslie]

When setting the Current Directory for tftpd64 you cannot paste in a path which exceeds the visible size of the field. At least on my system, the tftpd64 window is quite small on launch and so needs to be resized before I can paste in a path longer than ~32 characters.

Reproduction steps

1. Launch tftpd64
2. Attempt to set the Current Directory to a reasonably long path by pasting it in to the field
3. Observe the path will be truncated to be no longer than the visible width of the field

Workaround

Resize the application window so the Current Directory field is wide enough to fit the entire path to be pasted in.
