Detailed Description

A custom proxy model for sorting items in views.

The CustomProxyModel class provides a custom proxy model for sorting items in views, such as QTreeView or QListView. It extends QSortFilterProxyModel and adds custom behavior like sorting mount points before non-mount points on the desktop.

Constructor & Destructor Documentation

CustomProxyModel()

CustomProxyModel::CustomProxyModel

(

QObject *

parent = nullptr

)

Constructs a CustomProxyModel object.

Parameters

parent

The parent QObject.

Member Function Documentation

filterAcceptsRow()

bool CustomProxyModel::filterAcceptsRow ( int  sourceRow, const QModelIndex &  sourceParent  ) const

overrideprotected

Returns whether the item in the row indicated by the given source row and source parent should be included in the model or whether it should be filtered out.

Parameters

sourceRow	The source row.
sourceParent	The source parent.

Returns

True if the item should be included; otherwise returns false.

lessThan()

bool CustomProxyModel::lessThan ( const QModelIndex &  left, const QModelIndex &  right  ) const

override

Returns whether the item referred to by the given index is less than the item referred to by the given other index. Used for sorting. Sorts mount points before non-mount points.

Parameters

left	The left index.
right	The right index.

Returns

True if the item referred to by the left index is less than the item referred to by the right index; otherwise returns false. Mount points come before non-mount points on the desktop.

setFilteringEnabled()

void CustomProxyModel::setFilteringEnabled

(

bool

enable

)

Toggles the filtering behavior on/off.

Parameters

enable

True to enable filtering, false to disable it.

setSourceModel()

void CustomProxyModel::setSourceModel ( QAbstractItemModel *  sourceModel )

override

Sets the source model for the proxy model to sourceModel. We override this because we read the hidden file names from the .hidden file when the source model is set.

Parameters

sourceModel

The source model.
