Method Details

[hide private]

init(self, *args, **kwargs)
(Constructor)

x.__init__(...) initializes x; see help(type(x)) for signature

Overrides: object.__init__: (inherited documentation)

sizeHint(self, option, index)

Return the size hint for the element at the specified index

Note that this is only called if the view resizes rows to fit elements

Parameters:

option (QtGui.QStyleOptionViewItemV4) - The option to modify with cached information
index (QtCore.QModelIndex) - The index in the model

Returns: QSizeHint

The size hint for the element with height appropriately adjusted

Overrides: PyQt4.QtGui.QAbstractItemDelegate.sizeHint

getScaledValue(self, index)

Return the value scaled for the height of the bar

The value will be 0 if the data is None or if the range is None or 0.

Parameters:

index (QtCore.QModelIndex) - The index in the model

Returns: float

The value scaled appropriately to the full height of the bar

getBarCoordinates(self, option, index)

Returns the coordinates for the bar to be drawn in the element at the specified index

Parameters:

option (QtGui.QStyleOptionViewItemV4) - The option to modify with cached information
index (QtCore.QModelIndex) - The index in the model

Returns: tuple of QtCore.QPointF

The top left and bottom right coordinates of the bar

paint(self, painter, option, index)

Paint a bar with the specified painter in the location specified by option that matches the data at the specified index in the model

If the data at the index cannot be converted to a bar, the parent's paint method is called

Parameters:

option (QtGui.QStyleOptionViewItemV4) - The option to modify with cached information
index (QtCore.QModelIndex) - The index in the model

Overrides: PyQt4.QtGui.QAbstractItemDelegate.paint

element_height

Return the height of the element. Bar rows are twice the default.

rtype: float return: The height of the element

Get Method:: unreachable.element_height(self) - Return the height of the element.
