phoenix_title wx.FileConfig

wx.FileConfig implements wx.ConfigBase interface for storing and retrieving configuration information using plain text files.

The files have a simple format reminiscent of Windows INI files with lines of the form "key = value" defining the keys and lines of special form "[group]" indicating the start of each group.

This class is used by default for Config on Unix platforms but may also be used explicitly if you want to use files and not the registry even under Windows.

method_summary Methods Summary

__init__

Constructor allowing to choose the file names to use.

DeleteAll

Delete the whole underlying object (disk file, registry key, …).

DeleteEntry

Deletes the specified entry and the group it belongs to if it was the last key in it and the second parameter is True.

DeleteGroup

Delete the group (with all subgroups).

DisableAutoSave

Prevent this object from saving data to the disk file when it is destroyed.

EnableAutoSave

Enables saving data to the disk file when this object is destroyed.

Flush

Permanently writes all changes (otherwise, they’re only written from object’s destructor).

GetGlobalFileName

GetLocalFileName

GetNumberOfEntries

Get number of entries in the current group.

GetNumberOfGroups

Get number of entries/subgroups in the current group, with or without its subgroups.

GetPath

Retrieve the current path (always as absolute path).

HasEntry

HasGroup

RenameEntry

Renames an entry in the current group.

RenameGroup

Renames a subgroup of the current group.

Save

Saves all config data to the given stream, returns True if data was saved successfully or False on error.

SetPath

Set current path: if the first character is ‘/’, it is the absolute path, otherwise it is a relative path.

SetUmask

Allows setting the mode to be used for the config file creation.

class wx.FileConfig(ConfigBase)

Possible constructors:

FileConfig(appName="", vendorName="",
           localFilename="", globalFilename="",
           style=CONFIG_USE_LOCAL_FILE|CONFIG_USE_GLOBAL_FILE)

FileConfig(is)

FileConfig implements ConfigBase interface for storing and retrieving configuration information using plain text files.


Methods

__init__(self, *args, **kw)

overload Overloaded Implementations:



__init__ (self, appName=””, vendorName=””, localFilename=””, globalFilename=””, style=CONFIG_USE_LOCAL_FILE|CONFIG_USE_GLOBAL_FILE)

Constructor allowing to choose the file names to use.

If localFilename and/or globalFilename are explicitly specified, they are used as the names of the user and system-wide configuration files (the latter is only read by the program while the former is read from and written to). Otherwise the behaviour depends on style parameter. If it includes CONFIG_USE_LOCAL_FILE, then the local file name is constructed from the information in appName and vendorName arguments in a system-dependent way. If CONFIG_USE_GLOBAL_FILE is not specified at all (and globalFilename is empty) then the system-wide file is not used at all. Otherwise its name and path are also constructed in the way appropriate for the current platform from the application and vendor names.

Parameters:
  • appName (string) –

  • vendorName (string) –

  • localFilename (string) –

  • globalFilename (string) –

  • style (long) –



__init__ (self, is)

Read the config data from the specified stream instead of the associated file, as usual.

Parameters:

is (wx.InputStream) –

Save





DeleteAll(self)

Delete the whole underlying object (disk file, registry key, …).

Primarily for use by uninstallation routine.

Return type:

bool



DeleteEntry(self, key, bDeleteGroupIfEmpty=True)

Deletes the specified entry and the group it belongs to if it was the last key in it and the second parameter is True.

Parameters:
  • key (string) –

  • bDeleteGroupIfEmpty (bool) –

Return type:

bool



DeleteGroup(self, key)

Delete the group (with all subgroups).

If the current path is under the group being deleted it is changed to its deepest still existing component. E.g. if the current path is "/A/B/C/D" and the group C is deleted, the path becomes "/A/B" .

Parameters:

key (string) –

Return type:

bool



DisableAutoSave(self)

Prevent this object from saving data to the disk file when it is destroyed.

By default, changes to this object are only saved permanently when Flush is explicitly called or when it is destroyed. If this method is called, Flush won’t be called automatically from the destructor, meaning that any non-explicitly-flushed changes will be lost.

New in version 4.1/wxWidgets-3.1.3.



EnableAutoSave(self)

Enables saving data to the disk file when this object is destroyed.

This is the default behaviour and this function doesn’t need to be called explicitly unless DisableAutoSave had been previously called.

New in version 4.1/wxWidgets-3.1.3.



Flush(self, bCurrentOnly=False)

Permanently writes all changes (otherwise, they’re only written from object’s destructor).

Parameters:

bCurrentOnly (bool) –

Return type:

bool



static GetGlobalFileName(szFile)
Parameters:

szFile (string) –

Return type:

string



static GetLocalFileName(szFile, style=0)
Parameters:
  • szFile (string) –

  • style (int) –

Return type:

string



GetNumberOfEntries(self, bRecursive=False)

Get number of entries in the current group.

Parameters:

bRecursive (bool) –

Return type:

int



GetNumberOfGroups(self, bRecursive=False)

Get number of entries/subgroups in the current group, with or without its subgroups.

Parameters:

bRecursive (bool) –

Return type:

int



GetPath(self)

Retrieve the current path (always as absolute path).

Return type:

string



HasEntry(self, strName)
Parameters:

strName (string) –

Return type:

bool

Returns:

True if the entry by this name exists.



HasGroup(self, strName)
Parameters:

strName (string) –

Return type:

bool

Returns:

True if the group by this name exists.



RenameEntry(self, oldName, newName)

Renames an entry in the current group.

The entries names (both the old and the new one) shouldn’t contain backslashes, i.e. only simple names and not arbitrary paths are accepted by this function.

Parameters:
  • oldName (string) –

  • newName (string) –

Return type:

bool

Returns:

False if oldName doesn’t exist or if newName already exists.



RenameGroup(self, oldName, newName)

Renames a subgroup of the current group.

The subgroup names (both the old and the new one) shouldn’t contain backslashes, i.e. only simple names and not arbitrary paths are accepted by this function.

Parameters:
  • oldName (string) –

  • newName (string) –

Return type:

bool

Returns:

False if oldName doesn’t exist or if newName already exists.



Save(self, os)

Saves all config data to the given stream, returns True if data was saved successfully or False on error.

Return type:

bool



SetPath(self, strPath)

Set current path: if the first character is ‘/’, it is the absolute path, otherwise it is a relative path.

‘..’ is supported. If strPath doesn’t exist, it is created.

Parameters:

strPath (string) –



SetUmask(self, mode)

Allows setting the mode to be used for the config file creation.

For example, to create a config file which is not readable by other users (useful if it stores some sensitive information, such as passwords), you could use SetUmask(0077) .

This function doesn’t do anything on non-Unix platforms.

Parameters:

mode (int) –
