Method Details

[hide private]

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
