The icons referenced by the file association are managed by the Icon Dictionary; this guarantees that each icon is loaded only once into memory. The associations are determined by the information by the FOX Registry settings; each entry under the FILETYPES registry section comprises the command line, extension name, large icon, small icon, and mime type:
command ';' extension ';' bigicon [ ':' bigiconopen ] ';' icon [ ':' iconopen ] ';' mime [ ';' flags ]
For example, the binding for "jpg" could be:
xv s &;JPEG Image;bigimage.xpm;miniimage.xpm;image/jpeg;term
The association for a file name is determined by first looking at the entire file name, then at the whole extension, and then at sub-extensions. For example, "name.tar.gz", "tar.gz", and "gz" can each be given a different file association. Directory names may also be given associations; there is no command-line association for a directory, however. The association for a directory is found by first checking the whole pathname, then checking the pathname less the first component, and so on. So, "/usr/local/include", "/local/include", and "/include" can each be given their own file associations. If the above lookup procedure has not found a file association, the system uses a fallback associations: for files, the fallback association is determined by the binding "defaultfilebinding". For directories, the "defaultdirbinding" is used, and for executables the "defaultexecbinding" is used. The flags field is used for a number of bit-flags; two flags are currently defined: 'cd' and 'term'. The first one is intended to cause a launcher to execute the application in the shown directory; the second one is meant to indicate that the application is to be ran inside a new terminal.

Construct a dictionary mapping file-extension to file associations, using the application registry settings as a source for the bindings. The pointer to the application class is passed down to the icon source which is inside the icon dictionary. |
|
||||||||||||
|
Construct a dictionary mapping file-extension to file associations, using the specified settings database as a source for the bindings. The pointer to the application class is passed down to the icon source which is inside the icon dictionary. |

Destructor.
|
|
|
Change settings database.
|
|
|
Return settings database.
|
|
|
Change icon dictionary.
|
|
|
Return icon dictionary.
|
|
|
Set icon search path; the initial search path is determined by the "iconpath" registry setting in the SETTINGS section.
|
|
|
Return current icon search path.

Replace file association. The new association is written into the settings database under the FILETYPES section; the format of the association is as follows: <extension> = "<command> ; <type> ; <bigicon> [ : <bigopenicon> ] ; <smallicon> [ : <smalliconopen> ] ; <mimetype>" Where <command> is the command used to launch the application (e.g. "xv %s &"), and <type> is the file type string (e.g. "GIF Image"), <bigicon> and <bigiconopen> are the large icons shown in "Icons" mode, <smallicon> and <smalliconopen> are the small icons shown in "Details" mode, and <mimetype> is the RFC2045 mime type of the file. For example: [FILETYPES] gif="xv s &;GIF Image;big.xpm:bigopen.xpm;mini.xpm:miniopen.xpm;image/gif" /home/jeroen=";Home;home.xpm;minihome.xpm;application/x-folder" |
|
|
Remove file association.
Reimplemented from FX::FXDict. |
|
|
Find file association from registry.
|
|
|
Determine binding for the given file. The default implementation tries the whole filename first, then tries the extensions. For example, for a file "source.tar.gz": "source.tar.gz", "tar.gz", "gz" are tried in succession. If no association is found the key "defaultfilebinding" is tried as a fallback association. A NULL is returned if no association of any kind is found. |
|
|
Find directory binding from registry. The default implementation tries the whole pathname first, then tries successively smaller parts of the path. For example, a pathname "/usr/people/jeroen": "/usr/people/jeroen" "/people/jeroen" "/jeroen" are tried in succession. If no bindings are found, the key "defaultdirbinding" is tried as a fallback association. A NULL is returned if no association of any kind is found. |
|
|
Determine binding for the given executable. The default implementation returns the fallback binding associated with the key "defaultexecbinding". A NULL is returned if no association of any kind is found. |
|
|
Save to stream.
Reimplemented from FX::FXObject. |
|
|
Load from stream.
Reimplemented from FX::FXObject. |
|
|
Registry key used to find fallback executable icons.
|
|
|
Registry key used to find fallback directory icons.
|
|
|
Registry key used to find fallback document icons.
