makVre::DtRecursiveFileModel Class Reference

Detailed Description

DtRecursiveFileModel is a Qt model class that provides a list of files to QML list views. It manages a collection of file entries and exposes them through the Qt model-view framework, making them accessible to the UI.

Member Enumeration Documentation

FileModelRoles

enum makVre::DtRecursiveFileModel::FileModelRoles

Defines the custom roles used to access different aspects of the file entries.

Enumerator
FileNameRole	Role for accessing the file name.
FilePathRole	Role for accessing the file path.

Constructor & Destructor Documentation

DtRecursiveFileModel()

makVre::DtRecursiveFileModel::DtRecursiveFileModel

(

QObject *

parent = 0

)

Constructor.

Parameters

parent

Optional parent QObject for memory management

Creates a new empty file model.

Member Function Documentation

addFile()

virtual void makVre::DtRecursiveFileModel::addFile ( const DtFileEntry & entry )

virtual

Adds a file entry to the model.

Parameters

entry

File entry to add

Adds a new file entry to the end of the model's file list.

clear()

virtual void makVre::DtRecursiveFileModel::clear ( )

virtual

Clears all file entries from the model.

Removes all file entries from the model, leaving it empty.

sort()

virtual void makVre::DtRecursiveFileModel::sort ( int column, Qt::SortOrder order = Qt::AscendingOrder )

overridevirtual

Sorts the file entries.

Parameters

column	Column index to sort by (ignored in this implementation)
order	Sort order (ascending or descending)

Sorts the file entries case-insensitively using QCollator. This ensures proper alphabetical sorting regardless of locale.

removeRows()

virtual bool makVre::DtRecursiveFileModel::removeRows ( int row, int column = 0, const QModelIndex & parent = QModelIndex() )

overridevirtual

Removes rows from the model.

Parameters

row	Starting row index
column	Number of columns to remove (ignored in this implementation)
parent	Parent model index (ignored in this implementation)

Returns

True if rows were successfully removed

Implementation of QAbstractItemModel::removeRows for removing file entries.

rowCount()

virtual int makVre::DtRecursiveFileModel::rowCount ( const QModelIndex & parent = QModelIndex() ) const

overridevirtual

Gets the number of rows in the model.

Parameters

parent

Parent model index (ignored in this implementation)

Returns

Number of file entries in the model

Implementation of QAbstractItemModel::rowCount that returns the number of file entries.

data()

virtual QVariant makVre::DtRecursiveFileModel::data ( const QModelIndex & index, int role = Qt::DisplayRole ) const

overridevirtual

Gets data for a specific index and role.

Parameters

index	Model index to get data for
role	Data role to retrieve

Returns

Requested data as a QVariant

Implementation of QAbstractItemModel::data that provides access to file entry data.

setData()

virtual bool makVre::DtRecursiveFileModel::setData ( const QModelIndex & index, const QVariant & value, int role )

overridevirtual

Sets data for a specific index and role.

Parameters

index	Model index to set data for
value	New value to set
role	Data role to set

Returns

True if data was successfully set

Implementation of QAbstractItemModel::setData for updating file entry data.

roleNames()

virtual QHash< int, QByteArray > makVre::DtRecursiveFileModel::roleNames ( ) const

overrideprotectedvirtual

Gets the mapping from role IDs to role names.

Returns

Hash mapping role IDs to their name strings

Implementation of QAbstractItemModel::roleNames that provides the mapping from role enum values to the string names used in QML.

Member Data Documentation

myFiles

QList<DtFileEntry> makVre::DtRecursiveFileModel::myFiles

protected
