Member Enumeration Documentation
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 117 of file kextendableitemdelegate.cpp.
void KExtendableItemDelegate::contractItem | ( | const QModelIndex & | index | ) |
Close the extender that logically belongs to index
from the view.
The extender widget will be deleted.
Definition at line 104 of file kextendableitemdelegate.cpp.
QPixmap KExtendableItemDelegate::contractPixmap | ( | ) | [protected] |
Return the pixmap that is displayed to contract an item.
Definition at line 422 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 304 of file kextendableitemdelegate.cpp.
void KExtendableItemDelegate::extendItem | ( | QWidget * | extender, | |
const QModelIndex & | index | |||
) |
Insert the extender
that logically belongs to index
into the view.
If you need a parent for the extender at construction time, use the itemview's viewport(). The extender will be reparented and resized to the viewport by this function.
Definition at line 80 of file kextendableitemdelegate.cpp.
QPixmap KExtendableItemDelegate::extendPixmap | ( | ) | [protected] |
Return the pixmap that is displayed to extend an item.
Definition at line 416 of file kextendableitemdelegate.cpp.
bool KExtendableItemDelegate::isExtended | ( | const QModelIndex & | index | ) | const |
Return whether there is an extender that belongs to index
.
Definition at line 163 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 187 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 410 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 404 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 169 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.
