◆ actionRequested

void Digikam::DCategoryDrawer::actionRequested	(	int	action,
		const QModelIndex &	index
	)

signalinherited

Emit this signal on your subclass implementation to notify that something happened. Usually this will be triggered when you have received an event, and its position matched some "hot spot".

You give this action the integer you want, and having connected this signal to your code, the connected slot can perform the needed changes (view, model, selection model, delegate...)

◆ categoryHeight()

int Digikam::ItemCategoryDrawer::categoryHeight	(	const QModelIndex &	index,
		const QStyleOption &	option
	)		const

overridevirtual

Returns: The category height for the category represented by index index with style options option.

Reimplemented from Digikam::DCategoryDrawer.

◆ collapseOrExpandClicked

void Digikam::DCategoryDrawer::collapseOrExpandClicked ( const QModelIndex & index )

signalinherited

This signal becomes emitted when collapse or expand has been clicked.

◆ drawCategory()

void Digikam::ItemCategoryDrawer::drawCategory	(	const QModelIndex &	index,
		int	sortRole,
		const QStyleOption &	option,
		QPainter *	painter
	)		const

overridevirtual

This method purpose is to draw a category represented by the given

Parameters

index	with the given
sortRole	sorting role

Note: This method will be called one time per category, always with the first element in that category

Reimplemented from Digikam::DCategoryDrawer.

◆ mouseButtonDoubleClicked()

void Digikam::DCategoryDrawer::mouseButtonDoubleClicked	(	const QModelIndex &	index,
		const QRect &	blockRect,
		QMouseEvent *	event
	)

protectedvirtualinherited

Method called when the mouse button has been double clicked.

Parameters

index	The representative index of the block of items.
blockRect	The rect occupied by the block of items.
event	The mouse event.

Warning: You explicitly have to determine whether the event has been accepted or not. You have to call event->accept() or event->ignore() at all possible case branches in your code.

◆ mouseButtonPressed()

void Digikam::DCategoryDrawer::mouseButtonPressed	(	const QModelIndex &	index,
		const QRect &	blockRect,
		QMouseEvent *	event
	)

protectedvirtualinherited

Method called when the mouse button has been pressed.

Parameters

index	The representative index of the block of items.
blockRect	The rect occupied by the block of items.
event	The mouse event.

Warning: You explicitly have to determine whether the event has been accepted or not. You have to call event->accept() or event->ignore() at all possible case branches in your code.

◆ mouseButtonReleased()

void Digikam::DCategoryDrawer::mouseButtonReleased	(	const QModelIndex &	index,
		const QRect &	blockRect,
		QMouseEvent *	event
	)

protectedvirtualinherited

Method called when the mouse button has been released.

Parameters

index	The representative index of the block of items.
blockRect	The rect occupied by the block of items.
event	The mouse event.

Warning: You explicitly have to determine whether the event has been accepted or not. You have to call event->accept() or event->ignore() at all possible case branches in your code.

◆ mouseLeft()

void Digikam::DCategoryDrawer::mouseLeft	(	const QModelIndex &	index,
		const QRect &	blockRect
	)

protectedvirtualinherited

Method called when the mouse button has left this block.

Parameters

index	The representative index of the block of items.
blockRect	The rect occupied by the block of items.

◆ mouseMoved()

void Digikam::DCategoryDrawer::mouseMoved	(	const QModelIndex &	index,
		const QRect &	blockRect,
		QMouseEvent *	event
	)

protectedvirtualinherited

Method called when the mouse has been moved.

Parameters

index	The representative index of the block of items.
