Detailed Description

Customize the proxy model to display search results.

Features:

This has been tested with QTreeView and QTableView.
Manages expansion of nested items through DataRole::TO_EXPAND when applicable
Items with DataRole::TYPE == "title" are ignored

Member Function Documentation

◆ filterAcceptsRow()

bool filterAcceptsRow	(	const int	_srcRow,
		const QModelIndex &	_srcParent
	)		const

virtual

Overloaded Qt method. Customize so we accept rows where:

Each of the words can be found in its ancestors or itself, but not necessarily all words on the same row, or
One of its descendants matches rule 1, or
One of its ancestors matches rule 1.

For example this structure:

a – b – c — d
A search of "a" will display all rows.
A search of "b" or "a b" will display "a" and "b".
A search of "c", "d", "a c", "a d", "a c d" or "c d" will display "a", "c" and "d".
A search of "a b c d", "b c" or "b d" will display nothing.

Parameters

[in]	_srcRow	Row on the source model.
[in]	_srcParent	Parent on the source model.

Returns: True if row is accepted.

Reimplemented from QSortFilterProxyModel.

◆ FilterAcceptsRowItself()

bool FilterAcceptsRowItself	(	const int	_srcRow,
		const QModelIndex &	_srcParent,
		const QString &	_word
	)		const

Check if row contains the word on itself.

Parameters

[in]	_srcRow	Row on the source model.
[in]	_srcParent	Parent on the source model.
[in]	_word	Word to be checked.

Returns: True if row matches.

◆ HasAcceptedChildren()

bool HasAcceptedChildren	(	const int	_srcRow,
		const QModelIndex &	_srcParent
	)		const

Check if any of the children is fully accepted.

Parameters

[in]	_srcRow	Row on the source model.
[in]	_srcParent	Parent on the source model.

Returns: True if any of the children match.

◆ HasChildAcceptsItself()

bool HasChildAcceptsItself	(	const QModelIndex &	_srcParent,
		const QString &	_word
	)		const

Check if any of the children accepts a specific word.

Parameters

[in]	_srcParent	Parent on the source model.
[in]	_word	Word to be checked.

Returns: True if any of the children match.

◆ SetSearch()

void SetSearch ( const QString & _search )

Set a new search value.

Parameters

[in] _search Full search string.
