Protected Attributes | |
QY2DiskUsageList * | _diskUsageList |
Abstract base class for one partition ( mount point ) to display in a QY2DiskUsageList.
This class contains pure virtuals, so it cannot be used directly.
Definition at line 96 of file QY2DiskUsageList.h.
QY2DiskUsageListItem::QY2DiskUsageListItem | ( | QY2DiskUsageList * | parent | ) | [protected] |
Constructor.
Call updateData() after the constructor for the initial display update. Unfortunately, this cannot be done automatically in the constructor since it uses virtual methods that are not available yet at this point.
Definition at line 219 of file QY2DiskUsageList.cc.
QY2DiskUsageListItem::~QY2DiskUsageListItem | ( | ) | [protected, virtual] |
Destructor.
Definition at line 228 of file QY2DiskUsageList.cc.
virtual QString QY2DiskUsageListItem::deviceName | ( | ) | const [inline, virtual] |
The device name of this partition.
Derived classes may choose to reimplement this method. This default implementation returns an empty std::string.
Definition at line 166 of file QY2DiskUsageList.h.
FSize QY2DiskUsageListItem::freeSize | ( | ) | const [virtual] |
The current free size of this partition.
Derived classes can choose reimpmenent this if it is less expensive than calculating this value each time from usedSize() and totalSize() which is the default implementation.
Definition at line 269 of file QY2DiskUsageList.cc.
void QY2DiskUsageListItem::init | ( | bool | allFields | ) | [protected] |
( Re- ) initialize fields - all displayed fields ( if 'allFields' is 'true' ) or only the varying fields ( used, free, percentage ).
Definition at line 237 of file QY2DiskUsageList.cc.
virtual QString QY2DiskUsageListItem::name | ( | ) | const [pure virtual] |
The name to display for this partition. It makes most sense to use the mount point here ( but this is not a requirement ). This is what will be displayed in the "Name" column.
Derived classes need to implement this method.
bool QY2DiskUsageListItem::operator< | ( | const QTreeWidgetItem & | otherListViewItem | ) | const [virtual] |
Comparison function used for sorting the list. Reimplemented from QTreeWidgetItem
Reimplemented from QY2ListViewItem.
Definition at line 309 of file QY2DiskUsageList.cc.
void QY2DiskUsageListItem::paintPercentageBar | ( | QPainter * | painter, |
QStyleOptionViewItem | option, | ||
const QColor & | fillColor | ||
) |
Paint method.
Reimplemented from QY2ListViewItem. Paint a percentage bar into a QListViewItem cell. 'width' is the width of the entire cell. 'indent' is the number of pixels to indent the bar.

void QY2DiskUsageListItem::setText | ( | int | column, |
const QString & | text | ||
) | [inline] |
Re-declare ordinary setText() method so the compiler doesn't get confused which one to use.
Definition at line 189 of file QY2DiskUsageList.h.
void QY2DiskUsageListItem::setText | ( | int | column, |
const FSize & | size | ||
) |
Set a column text via FSize.
Definition at line 261 of file QY2DiskUsageList.cc.
virtual FSize QY2DiskUsageListItem::totalSize | ( | ) | const [pure virtual] |
The total size of this partition.
Derived classes need to implement this method.
void QY2DiskUsageListItem::updateData | ( | ) | [virtual] |
Update this item's data completely. Triggered by QY2ListView::updateAllItemData().
Reimplemented from QY2ListViewItem.
Reimplemented from QY2ListViewItem.
Definition at line 295 of file QY2DiskUsageList.cc.
void QY2DiskUsageListItem::updateStatus | ( | ) | [virtual] |
Update this item's status ( here: the numeric fields ). Triggered by QY2ListView::updateAllItemStates().
Reimplemented from QY2ListViewItem.
Reimplemented from QY2ListViewItem.
Definition at line 288 of file QY2DiskUsageList.cc.
int QY2DiskUsageListItem::usedPercent | ( | ) | const [virtual] |
The currently used percentage ( 0..100 ) of this partition.
Derived classes can choose reimpmenent this if it is less expensive than calculating this value each time from usedSize() and totalSize() which is the default implementation.
Definition at line 276 of file QY2DiskUsageList.cc.
virtual FSize QY2DiskUsageListItem::usedSize | ( | ) | const [pure virtual] |
The currently used size of this partition.
Derived classes need to implement this method.
