    Pkg View for QDirStat

Idea

New view to display information about installed packages from the package manager.
Very much like the normal tree view and treemap, but the top level would be packages.
foo.deb
  usr
    bin
      foo
    share
      lib
        foo
          foo-list.dat
          foo-users.dat
bar_i386.deb
  usr
    lib32
      libbar.so.42
      libbar.so.42.1.0
bar_amd64.deb
  usr
    lib
      libbar.so.42
      libbar.so.42.1.0

Implementation

class PkgInfo: public DirInfo
class PkgReadJob: public DirReadJob


Get a list of all installed packages from the system's package manager
Iterate over all those packages: For each one

Put it into a DirTree
Get a file list for that package; for each entry

create the directory nodes under the package node

lstat() for the entry
create a FileInfo for the entry


Dpkg Commands

Get a list of all installed packages

dpkg -l

(Poor formatting)
Better:

Get the file list for a package

dpkg -L <pkg-name>
dpkg --listfiles <pkg-name>

Rpm Commands

rpm -qa --queryformat ...

Get the file list for a package

rpm -ql <pkg-name>
