wx.FileHistory and wx.Config

[Steven Sproat]

Hi,

I'm trying to get my file history to read/write to a wx config file. I
currently using the external python module ConfigObj for my
configuration files, but it seems wx has a way for the file history to
work with wx.config automatically, so that seems the easiest route to take.

self.filehistory = wx.FileHistory(5)
self.config = wx.Config("Whyteboard")
self.config.SetPath(os.path.join(get_home_directory,
"directories.list"))
self.filehistory.Load(self.config)

At this point, no config file exists, but I thought wx would auto-create
it or something, can't find too many examples of config
And in my file open handler:

def handle_files(self, path):
self.directory = os.path.dirname(path)
self.filehistory.AddFileToHistory(path)
self.filehistory.Save(self.config)

if path.endswith(".wtbd"):
self.util.load_wtbd(path)
else:
self.util.temp_file = path
self.util.load_file()

And my "utility" function:

def get_home_dir(extra_path=None):
std_paths = wx.StandardPaths.Get()
path = wx.StandardPaths.GetUserLocalDataDir(std_paths)
if extra_path:
path = os.path.join(path, extra_path, "") # "" forces slash at end

if not os.path.isdir(path):
os.makedirs(path)
return path

I was hoping that the x many "last remembered" files in
self.filehistory's constructor would be auto-written into the config
file every time I loaded a file, but it's not the case. I'm not sure if
I have to explicitly write the changes, or even explicitly create the
config file, as it doesn't get created.
regards,

Hi all,

2009/12/28 Steven Sproat <spr...@gmail.com>

I've now fixed the issue, with much less code. I wasn't adding the existing files to the menu.

def __init__(self):
        self.filehistory = wx.FileHistory(8)       
        self.config = wx.Config("Whyteboard",style=wx.CONFIG_USE_LOCAL_FILE)
        self.filehistory.Load(self.config)

        recent = wx.Menu()
        self.filehistory.UseMenu(recent)
        self.filehistory.AddFilesToMenu()

def on_open(self, path):
        self.filehistory.AddFileToHistory(path)
        self.filehistory.Save(self.config)
 

Here's hoping it comes in handy to someone. Cheers!

SetPath does not set the path or filename of the file used to store the
config data. It sets the name of the active group within the config
data. (Hierarchical groups are allowed, that's why it allows the use of
path syntax.)

Unless you explicitly use wx.FileConfig then on Windows it will actually
put the stuff in the registry. Look under HKCU/Software/Whyteboard

ah right. However, this doesn't work under gtk (python 2.6.2, wx
2.8.10.1 - is there anytyhing linux-specific that I'm not doing? all is
well on winxp sp3

Try specifying the vendor name in addition to the app name. If that
still has problems then you can use wx.FileConfig and also specify the
filename to use.

Here is my code using wx.FileConfig

self.filehistory = wx.FileHistory(9)
self.fileConfig = wx.FileConfig(appName="ApplicationName",
vendorName="VendorName",
localFilename="file.cfg",
style=wx.CONFIG_USE_LOCAL_FILE)
self.filehistory.Load(self.fileConfig)
self.filehistory.UseMenu(file_menu)
self.filehistory.AddFilesToMenu()

Where is the location of the file "file.cfg"?

Two files are added to .cfg. Once application starts, It shows
complete file path in menu. Either open another file or click file
menu item, all the file menu items suddenly changes to short file name
(name.ext). Is there something wrong here?

On Windows If you have HOME set in the environment then it will go
there. Otherwise it is under your "c:\Documents and Settings\userName"
folder, but I don't remember exactly where. Try searching for it with
Explorer.

No. The paths are shown relative to the current working directory, so
if that changes to the same location as the files then they are shown
with no path.
