Detailed Description

Item delegate for rendering items in Plasma menus implemented with item views.

The delegate makes use of its own data roles that are: SubTitleRole: the text of the subtitle SubTitleMandatoryRole: if the subtitle is to always be displayed (as default the subtitle is displayed only on mouse over) NOTE: if model doesn't return a valid data for SubTitleMandatoryRole (i.e. if it returns QVaraint()) then subtitles will be shown for adjasent items with the same content and not shown otherwise.

ColumnTypeRole: if the column is a main column (with title and subtitle) or a secondary action column (only a little icon that appears on mouse over is displayed)

Member Function Documentation

QRect Plasma::Delegate::emptyRect	(	const QStyleOptionViewItem &	option,
		const QModelIndex &	index
	)		const

protected

Returns the empty area after both the title and the subtitle.

The height is the height of the item. It can be used by subclasses that wants to paint additional data

Parameters

option	options for the title and subtitle text
index	model index that we want to compute the free area

Definition at line 207 of file delegate.cpp.

void Plasma::Delegate::paint	(	QPainter *	painter,
		const QStyleOptionViewItem &	option,
		const QModelIndex &	index
	)		const

virtual

Definition at line 218 of file delegate.cpp.

QRect Plasma::Delegate::rectAfterSubTitle	(	const QStyleOptionViewItem &	option,
		const QModelIndex &	index
	)		const

protected

Returns the empty area after the subtitle.

The height is the height of the subtitle. It can be used by subclasses, that wants to paint additional data.

Parameters

option	options for the subtitle text
index	model index that we want to compute the free area

Definition at line 188 of file delegate.cpp.

QRect Plasma::Delegate::rectAfterTitle	(	const QStyleOptionViewItem &	option,
		const QModelIndex &	index
	)		const

protected

Returns the empty area after the title.

The height is the height of the subtitle. It can be used by subclasses that wants to paint additional data after calling the paint function of the superclass.

Parameters

option	options for the title text
index	model index that we want to compute the free area

Definition at line 169 of file delegate.cpp.

int Plasma::Delegate::roleMapping ( SpecificRoles role ) const

Definition at line 164 of file delegate.cpp.

void Plasma::Delegate::setRoleMapping	(	SpecificRoles	role,
		int	actual
	)

Maps an arbitrary role to a role belonging to SpecificRoles.

Using this function you can use any model with this delegate.

Parameters

role	a role belonging to SpecificRoles
actual	an arbitrary role of the model we are using

Definition at line 159 of file delegate.cpp.

bool Plasma::Delegate::showToolTip ( ) const

Returns: true if a tooltip should be shown

Definition at line 485 of file delegate.cpp.

QSize Plasma::Delegate::sizeHint	(	const QStyleOptionViewItem &	option,
		const QModelIndex &	index
	)		const
