/* The following class is the base class for all of the archive types.
|
|
* In order for it to work properly with the TDEProcess, you have to
|
|
* connect the ProcessExited signal appropriately before spawning
|
|
* the core operations. Then the signal that the process exited can
|
|
* be intercepted by the viewer (in ark, ArkWidget) and dealt with
|
|
* appropriately. See LhaArch or ZipArch for a good model. Don't use
|
|
* TarArch or CompressedFile as models - they're too complicated!
|
|
*
|
|
* Don't forget to set m_archiver_program and m_unarchiver_program
|
|
* and add a call to
|
|
* verifyUtilityIsAvailable(m_archiver_program, m_unarchiver_program);
|
|
* in the constructor of your class. It's OK to leave out the second argument.
|
|
*
|
|
* To add a new archive type:
|
|
* 1. Create a new header file and a source code module
|
|
* 2. Add an entry to the ArchType enum in arch.h.
|
|
* 3. Add appropriate types to buildFormatInfo() in archiveformatinfo.cpp
|
|
* and archFactory() in arch.cpp
