[Pgu-devel] FileDialog questions / enhancements.

[Russell S. <se...@cs...>]

I noticed some usability problems with FileDialog in pgu-0.9.  Do you
want patches for any of these?

(1) The user must click on the file name input field before typing a
file name.

To work around this, I open the dialog like this:

d = FileDialog(...)
...
d.input_file.container.focus(d.input_file)
d.open()

(2) There is no way to ask the file dialog to refresh itself.  I create
the dialog once, and then call open() and close() on it so that it
remembers its state from invocation to invocation.  If you save to a new
file, it won't show up the next time you open a file dialog!

To work around this, I do this before I call open():

d.list.clear()
d._list_dir_()

(This might belong in its own method, otherwise, it should probably be
added to open())

(3) Pressing enter doesn't dismiss the file dialog

To work around this, I call:

d._button_okay_clicked_(None)

from my game's event loop.  Should FileDialog listen for the keyboard event?

(4) escape doesn't work

Same as (3), except you need to call d.close()

There are a few more annoyances that I don't have work arounds for:

- <tab> doesn't behave as expected (it cycles to 'ok' before cycling to
the file list, and then cycles through the visible list elements, and
then breaks)
- <shift-tab> behaves like tab
- the arrow keys don't work in the file list

I don't understand enough about dialog's handling of <tab> to fix these.
 Any ideas?

Thanks,
Rusty
