Detailed Description

This class makes it easy to add a search line for filtering the items in a iconview based on a simple text search.

No changes to the application other than instantiating this class with an appropriate QIconView should be needed.

Since:

Constructor & Destructor Documentation

KIconViewSearchLine::KIconViewSearchLine	(	QWidget *	parent = 0,
		QIconView *	iconView = 0,
		const char *	name = 0
	)

Constructs a KIconViewSearchLine with iconView being the QIconView to be filtered.

If iconView is null then the widget will be disabled until a iconview is set with setIconView().

Definition at line 57 of file kiconviewsearchline.cpp.

KIconViewSearchLine::KIconViewSearchLine	(	QWidget *	parent,
		const char *	name
	)

Constructs a KIconViewSearchLine without any QIconView to filter.

The QIconView object has to be set later with setIconView().

Definition at line 66 of file kiconviewsearchline.cpp.

KIconViewSearchLine::~KIconViewSearchLine

(

)

[virtual]

Destroys the KIconViewSearchLine.

Member Function Documentation

void KIconViewSearchLine::activateSearch

(

)

[protected, slot]

When the timer started with queueSearch() expires this slot is called.

If there has been another timer started then this slot does nothing. However if there are no other pending searches this starts the icon view search.

queueSearch()

Definition at line 254 of file kiconviewsearchline.cpp.

bool KIconViewSearchLine::caseSensitive

(

)

const

Returns true if the search is case sensitive.

This defaults to false.

setCaseSensitive()

Definition at line 79 of file kiconviewsearchline.cpp.

void KIconViewSearchLine::clear

(

)

[virtual, slot]

Clear line edit and empty hiddenItems, returning elements to iconView.

Reimplemented from KLineEdit.

Definition at line 137 of file kiconviewsearchline.cpp.

void KIconViewSearchLine::hideItem

(

QIconViewItem *

item

)

[protected]

Hide item.

Definition at line 222 of file kiconviewsearchline.cpp.

QIconView * KIconViewSearchLine::iconView

(

)

const

Returns the iconview that is currently filtered by the search.

See also:

setIconView()

Definition at line 84 of file kiconviewsearchline.cpp.

void KIconViewSearchLine::init

(

QIconView *

iconView = 0

)

[protected]

Do initialization common to both constructors.

Definition at line 202 of file kiconviewsearchline.cpp.

bool KIconViewSearchLine::itemMatches	(	const QIconViewItem *	item,
		const QString &	s
	)			const [protected, virtual]

Returns true if item matches the search s.

This will be evaluated based on the value of caseSensitive(). This can be overridden in subclasses to implement more complicated matching schemes.

Definition at line 190 of file kiconviewsearchline.cpp.

void KIconViewSearchLine::queueSearch

(

const QString &

s

)

[protected, slot]

When keys are pressed a new search string is created and a timer is activated.

The most recent search is activated when this timer runs out if another key has not yet been pressed.

This method makes

Parameters:

s

the most recent search and starts the timer.

Together with activateSearch() this makes it such that searches are not started until there is a short break in the users typing.

Definition at line 247 of file kiconviewsearchline.cpp.

void KIconViewSearchLine::setCaseSensitive

(

bool

cs

)

[slot]

Make the search case sensitive or case insensitive.

See also:

caseSenstive()

Definition at line 164 of file kiconviewsearchline.cpp.

void KIconViewSearchLine::setIconView

(

QIconView *

iv

)

[slot]

Sets the QIconView that is filtered by this search line.

If lv is null then the widget will be disabled.

iconView()

Definition at line 169 of file kiconviewsearchline.cpp.

void KIconViewSearchLine::showItem

(

QIconViewItem *

item

)

[protected]

Show item.

Just unhide it, doesn't necessary show it on screen, for that use iconView->ensureItemVisible()

Definition at line 231 of file kiconviewsearchline.cpp.

void KIconViewSearchLine::updateSearch

(

const QString &

s = QString::null

)

[virtual, slot]

Updates search to only make visible the items that match s.

If s is null then the line edit's text will be used.
