Constructor & Destructor Documentation
KExtendableItemDelegate::KExtendableItemDelegate | ( | QAbstractItemView * | parent | ) |
Create a new KExtendableItemDelegate that belongs to parent
.
In contrast to generic QAbstractItemDelegates, an instance of this class can only ever be the delegate for one instance of af QAbstractItemView subclass.

Member Function Documentation
void KExtendableItemDelegate::contractAll | ( | ) |
Close all extenders and delete all extender widgets.
Definition at line 120 of file kextendableitemdelegate.cpp.
void KExtendableItemDelegate::contractItem | ( | const QModelIndex & | index | ) |
Remove the extender of item at index
from the view.
The extender widget will be deleted.
Definition at line 101 of file kextendableitemdelegate.cpp.
QPixmap KExtendableItemDelegate::contractPixmap | ( | ) | [protected] |
Return the pixmap that is displayed to contract an item.
Definition at line 435 of file kextendableitemdelegate.cpp.
void KExtendableItemDelegate::extenderCreated | ( | QWidget * | extender, | |
const QModelIndex & | index | |||
) | [signal] |
This signal indicates that the item at index
was extended with extender
.
void KExtendableItemDelegate::extenderDestroyed | ( | QWidget * | extender, | |
const QModelIndex & | index | |||
) | [signal] |
This signal indicates that the extender
belonging to index
has emitted the destroyed() signal.
QRect KExtendableItemDelegate::extenderRect | ( | QWidget * | extender, | |
const QStyleOptionViewItem & | option, | |||
const QModelIndex & | index | |||
) | const [protected] |
Reimplement this function to fine-tune the position of the extender.
option.rect
will be a rectangle that is as wide as the viewport and as high as the usual item height plus the extender size hint's height. Its upper left corner will be at the upper left corner of the usual item. You can place the returned rectangle of this function anywhere inside that area.
Definition at line 309 of file kextendableitemdelegate.cpp.
void KExtendableItemDelegate::extendItem | ( | QWidget * | extender, | |
const QModelIndex & | index | |||
) |
Insert the extender
for item at index
into the view.
If you need a parent for the extender at construction time, use the itemview's viewport(). The delegate takes ownership of the extender; the extender will also be reparented and resized to the viewport.
Definition at line 76 of file kextendableitemdelegate.cpp.
QPixmap KExtendableItemDelegate::extendPixmap | ( | ) | [protected] |
Return the pixmap that is displayed to extend an item.
Definition at line 429 of file kextendableitemdelegate.cpp.
bool KExtendableItemDelegate::isExtended | ( | const QModelIndex & | index | ) | const |
Return whether there is an extender that belongs to index
.
Definition at line 162 of file kextendableitemdelegate.cpp.
void KExtendableItemDelegate::paint | ( | QPainter * | painter, | |
const QStyleOptionViewItem & | option, | |||
const QModelIndex & | index | |||
) | const [virtual] |
Re-implemented for internal reasons.
API not affected.
Definition at line 188 of file kextendableitemdelegate.cpp.
void KExtendableItemDelegate::setContractPixmap | ( | const QPixmap & | pixmap | ) | [protected] |
The pixmap that is displayed to contract an item.
pixmap
must have the same size as the pixmap in setExtendPixmap.
Definition at line 423 of file kextendableitemdelegate.cpp.
void KExtendableItemDelegate::setExtendPixmap | ( | const QPixmap & | pixmap | ) | [protected] |
The pixmap that is displayed to extend an item.
pixmap
must have the same size as the pixmap in setContractPixmap.
Definition at line 417 of file kextendableitemdelegate.cpp.
QSize KExtendableItemDelegate::sizeHint | ( | const QStyleOptionViewItem & | option, | |
const QModelIndex & | index | |||
) | const [virtual] |
Re-implemented for internal reasons.
API not affected.
Definition at line 168 of file kextendableitemdelegate.cpp.
void KExtendableItemDelegate::updateExtenderGeometry | ( | QWidget * | extender, | |
const QStyleOptionViewItem & | option, | |||
const QModelIndex & | index | |||
) | const [virtual] |
Reimplement this function to adjust the internal geometry of the extender.
The external geometry of the extender will be set by the delegate.
