Detailed Description

Qt model for displaying recent capture files.

This is a thin wrapper over WorkspaceState — it does not store data, but provides a Qt model interface for views.

Thread safety: Assumes single-threaded access (UI thread only).

Member Enumeration Documentation

RecentFileRoles

enum RecentCaptureFilesListModel::RecentFileRoles

Custom data roles for RecentCaptureFilesListModel.

Enumerator
FilenameRole	QString — absolute path of the capture file.
FileSizeRole	qint64 — file size in bytes; -1 if unknown.
AccessibleRole	bool — true if the file exists and is readable.

Constructor & Destructor Documentation

RecentCaptureFilesListModel()

RecentCaptureFilesListModel::RecentCaptureFilesListModel ( QObject *  parent = nullptr )

explicit

Constructs the model and connects it to WorkspaceState change notifications.

Parameters

parent

Optional parent QObject.

Member Function Documentation

data()

QVariant RecentCaptureFilesListModel::data ( const QModelIndex &  index, int  role = Qt::DisplayRole  ) const

override

Returns data for the given index and role.

Parameters

index	Model index of the requested item.
role	Qt item data role or a RecentFileRoles value.

Returns

QVariant with the requested data, or an invalid QVariant if unavailable.

flags()

Qt::ItemFlags RecentCaptureFilesListModel::flags ( const QModelIndex &  index ) const

override

Returns item flags for the given index.

Inaccessible files are returned as non-enabled so they cannot be opened.

Parameters

index

Model index to query.

Returns

Qt::ItemIsEnabled | Qt::ItemIsSelectable for accessible files; Qt::ItemIsSelectable only for inaccessible ones.

rowCount()

int RecentCaptureFilesListModel::rowCount ( const QModelIndex &  parent = QModelIndex() ) const

override

Returns the number of recent capture file entries.

Parameters

parent

Unused; pass a default QModelIndex for list models.

Returns

Number of entries in WorkspaceState's recent file list.
