[Panel-devel] Plasma: Proposing some changes (for Aaron mostly)

[Ivan Čukić]

Maybe I do not see the whole picture, and I'm missing something that already 
exists but here it goes:

1. Add a function for resetting all data for Plasma::DataSource
Since the file/directory watching engine I'm working on needs to pass 
different sets of data for files and for directories, I need to reset the 
data that was set earlier. DataSource has data() function but it can not be 
used to change the data since it returns a const DataEngine::Data. I could 
override it by getting the list of set values and resetting them, but it 
would be slower than just being able to call the clear() method of QHash 
(DataEngine::Data)

2. Possible background issues
If the designer of the "standard background" wants to add some fancy border to 
it, the thickness of that border would be different for differently sized 
applets. Even more, if an applet is 400px wide and 200px high, the side 
borders would be twice as thick as the top and bottom borders which would 
look ugly.

3. Applets to register for certain mimetypes
I didn't find this in the docs so I suppose that it doesn't exist. :) I think 
it would be a good thing to have the ability to set acceptable mimetypes for 
applets so when a user drops a file on the desktop, the plasma would know 
which applet to load to display that file. If there are multiple choices, a 
menu could be shown.

'Nuf said for the moment, cheers
Ivan
