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) 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 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

bool Plasma::Delegate::showToolTip | ( | ) | const |
- Returns:
- true if a tooltip should be shown
