Detailed Description

The FileInfoProvider class is such an abstract class that using in CCIMXFileSystemModel to provide the file information, which, we can modify the file information provide easily in the model.

Constructor & Destructor Documentation

FileInfoProvider()

FileInfoProvider::FileInfoProvider ( CCIMXFileSystemModel *  models )

inline

Parameters

models

Member Function Documentation

currentHandlePath()

QString FileInfoProvider::currentHandlePath ( )

inline

currentHandlePath get the current handle path

Returns

the current handle path

data()

virtual std::pair< bool, QVariant > FileInfoProvider::data ( const QModelIndex &  index, int  role  )

pure virtual

functions provide what to display

Parameters

index	the model index
role	the role of the index

Returns

returns the data of the index, if the data is not available, it will return with {false, {}}

Note

for developers re-develop the sessions, you can modified to the implements with std::optional<QVariant>, QVariant itself invalid means something in model that is meaningful, so, QVariant's invalid don't mean the data itself invalid

Implemented in DirentSizeCounter, FileCountInfo, FileNameProviders, and FileTypeInfo.

provide_section_name()

virtual QString FileInfoProvider::provide_section_name ( )

inlinepure virtual

One InfoProvider for one section header name, the function do the case :)

Returns

the section name

Implemented in DirentSizeCounter, FileCountInfo, FileNameProviders, and FileTypeInfo.

setCurrentHandlePath()

void FileInfoProvider::setCurrentHandlePath ( const QString &  path )

inline

setCurrentHandlePath set the current handle path

Parameters

path	the path to be set
