Constructor & Destructor Documentation
ExpandingWidgetModel::ExpandingWidgetModel | ( | QWidget * | parent | ) |
Definition at line 42 of file expandingwidgetmodel.cpp.
ExpandingWidgetModel::~ExpandingWidgetModel | ( | ) | [virtual] |
Definition at line 47 of file expandingwidgetmodel.cpp.
Member Function Documentation
int ExpandingWidgetModel::basicRowHeight | ( | const QModelIndex & | index | ) | const [protected] |
Definition at line 353 of file expandingwidgetmodel.cpp.
void ExpandingWidgetModel::cacheIcons | ( | ) | const [protected] |
Definition at line 437 of file expandingwidgetmodel.cpp.
bool ExpandingWidgetModel::canCollapseCurrentItem | ( | ) | const |
- Returns:
- whether the current item can be collapsed
bool ExpandingWidgetModel::canExpandCurrentItem | ( | ) | const |
The following three are convenience-functions for the current item that could be replaced by the later ones.
- Returns:
- whether the current item can be expanded
void ExpandingWidgetModel::clearExpanding | ( | ) |
Unexpand all rows and clear all cached information about them(this includes deleting the expanding-widgets).
Definition at line 121 of file expandingwidgetmodel.cpp.
void ExpandingWidgetModel::clearMatchQualities | ( | ) |
Definition at line 110 of file expandingwidgetmodel.cpp.
virtual int ExpandingWidgetModel::contextMatchQuality | ( | const QModelIndex & | index | ) | const [protected, pure virtual] |
- Returns:
- the context-match quality from 0 to 10 if it could be determined, else -1
Implemented in KateArgumentHintModel, and KateCompletionModel.
QVariant ExpandingWidgetModel::data | ( | const QModelIndex & | index, | |
int | role = Qt::DisplayRole | |||
) | const [virtual] |
Does not request data from index, this only returns local data like highlighting for expanded rows and similar.
Reimplemented in KateArgumentHintModel, and KateCompletionModel.
Definition at line 86 of file expandingwidgetmodel.cpp.
QWidget * ExpandingWidgetModel::expandingWidget | ( | const QModelIndex & | row | ) | const |
- Returns:
- the expanding-widget for the given row, if available. Expanding-widgets are in best case available for all expanded rows. This does not return the partially-expand widget.
Definition at line 427 of file expandingwidgetmodel.cpp.
int ExpandingWidgetModel::expandingWidgetsHeight | ( | ) | const |
Returns the total height added through all open expanding-widgets.
Definition at line 416 of file expandingwidgetmodel.cpp.
virtual bool ExpandingWidgetModel::indexIsItem | ( | const QModelIndex & | index | ) | const [pure virtual] |
Should return true if the given row should be painted like a contained item(as opposed to label-rows etc.).
Implemented in KateArgumentHintModel, and KateCompletionModel.
bool ExpandingWidgetModel::isExpandable | ( | const QModelIndex & | index | ) | const |
- Returns:
- whether the row given through index is expandable
Definition at line 286 of file expandingwidgetmodel.cpp.
bool ExpandingWidgetModel::isExpanded | ( | const QModelIndex & | row | ) | const |
ExpandingWidgetModel::ExpansionType ExpandingWidgetModel::isPartiallyExpanded | ( | const QModelIndex & | index | ) | const |
Returns whether the given index is currently partially expanded. Does not do any other checks like calling models for data.
Definition at line 135 of file expandingwidgetmodel.cpp.
uint ExpandingWidgetModel::matchColor | ( | const QModelIndex & | index | ) | const |
Returns the match-color for the given index, or zero if match-quality could not be computed.
Definition at line 56 of file expandingwidgetmodel.cpp.
QRect ExpandingWidgetModel::partialExpandRect | ( | const QModelIndex & | row | ) | const |
Returns the rectangle for the partially expanded part of the given row.
Definition at line 247 of file expandingwidgetmodel.cpp.
QString ExpandingWidgetModel::partialExpandText | ( | const QModelIndex & | row | ) | const |
Definition at line 240 of file expandingwidgetmodel.cpp.
QModelIndex ExpandingWidgetModel::partiallyExpandedRow | ( | ) | const |
Returns the first row that is currently partially expanded.
Definition at line 114 of file expandingwidgetmodel.cpp.
int ExpandingWidgetModel::partiallyExpandWidgetHeight | ( | ) | const |
Amount by which the height of a row increases when it is partially expanded.
- Todo:
- use font-metrics text-height*2 for 2 lines
Definition at line 149 of file expandingwidgetmodel.cpp.
void ExpandingWidgetModel::partiallyUnExpand | ( | const QModelIndex & | index | ) | [protected] |
Definition at line 142 of file expandingwidgetmodel.cpp.
void ExpandingWidgetModel::placeExpandingWidget | ( | const QModelIndex & | row | ) |
Places and shows the expanding-widget for the given row, if it should be visible and is valid.
Also shows the partial-expanding-widget when it should be visible.
Definition at line 366 of file expandingwidgetmodel.cpp.
void ExpandingWidgetModel::placeExpandingWidgets | ( | ) | [slot] |
Place or hides all expanding-widgets to the correct positions. Should be called after the view was scrolled.
Definition at line 410 of file expandingwidgetmodel.cpp.
void ExpandingWidgetModel::rowSelected | ( | const QModelIndex & | row | ) | [virtual] |
Notifies underlying models that the item was selected, collapses any previous partially expanded line, checks whether this line should be partially expanded, and eventually does it.
Does nothing when nothing needs to be done. Does NOT show the expanding-widget. That is done immediately when painting by ExpandingDelegate, to reduce flickering.
- See also:
- showPartialExpandWidget()
- Parameters:
-
row The row
- Todo:
- allow multiple partially expanded rows
Reimplemented in KateCompletionModel.
Definition at line 153 of file expandingwidgetmodel.cpp.
void ExpandingWidgetModel::setCurrentItemExpanded | ( | bool | ) |
Expand/collapse the current item.
void ExpandingWidgetModel::setExpanded | ( | QModelIndex | index, | |
bool | expanded | |||
) |
Change the expand-state of the row given through index. The display will be updated.
Definition at line 307 of file expandingwidgetmodel.cpp.
virtual QTreeView* ExpandingWidgetModel::treeView | ( | ) | const [pure virtual] |
Implemented in KateArgumentHintModel.
