Hi,
I need your help in writing a simple kio slave to display contents of
a xml file (xml file follows a structure like a filesystem though
there will only be folders).
API documentation has not proved much useful. The easiest
example/source of kio slave implementation I could find was
'applications' slave.
>From there I am getting the impression that get() is the first method
called when the url is opened in e.g. konqueror. Here is how I do it:
-
void SKioSlave::get(const KUrl& url){
error( KIO::ERR_IS_DIRECTORY, url.prettyUrl() ); // We only have
folders in the tree
}
I'm not sure in which cases and when stat() and listDir() are called.
Here is my implementation of them (created just to get hold of
things).
void SKioSlave::stat(const KUrl& url){
KIO::UDSEntry entry;
if(url.path().size() == 0){ //base folder
createFolderEntry(entry, "Sparkle", "");
statEntry(entry);
finished();
return;
}
statEntry(entry);//Must be either Catalogue or invalid folder,
ignore for now
finished();
}
void SKioSlave::listDir(const KUrl& url){
KIO::UDSEntry entry;
if(url.path().size() != 0){// Category or invalid folder, mark them empty
listEntry(entry, true);
totalSize(0);
finished();
return;
}
//Base folder, we have only one sub folder i.e. Catalogue
createFolderEntry(entry, "Catalogue", "");
listEntry(entry, false);
listEntry(entry, true);
totalSize(1);
finished();
}
The problem is that when I open sparkle: in konqueror, it is forever
in loading state and it shows nothing. If I right click -> Properties
-> Calculate then correct number of subfolders (1) is shown, also name
of base folder (Sparkle) is shown.
What could be the problem here? What happens after I signal error in
the get() function?
Please help.

Yogesh Marwaha
