Method Details

[hide private]

_getScalingFactor(self, min_val, max_val)

Get a scaling factor to adjust a data value by.

Parameters:

min_val (float) - Minimum value
max_val (float) - Max value

Returns: float

Scaling factor

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 (QtWidgets.QStyleOptionViewItem) - 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

_getSelectionText(self, index)

Return the selection text

Subclasses can override this for custom selection behavior

Parameters:

index - The index in the model

Returns: basestr @return The text representation of the value or an empty string if None

Overrides: BaseRowDelegate._getSelectionText

(inherited documentation)

_paintWithBrush(self, painter, option, index, background_brush)

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 (QtWidgets.QStyleOptionViewItem) - The option to modify with cached information
index (QtCore.QModelIndex) - The index in the model
background_brush (QtGui.QBrush) - The brush to use

_paintSelection(self, painter, option, index)

We want the selection painted in the default way, but without colors

Parameters:

painter - The painter for the cell
option - The option for the cell
index - The index in the table

Overrides: BaseRowDelegate._paintSelection

_paintDefault(self, painter, option, index)

Paints the default (non-selected) cell using the specified painter, option, and index

Note: This method is overridden in subclasses and should not be merged into paint().

Parameters:

painter - The painter for the cell
option - The option for the cell
index - The index in the table
selection_brush - The brush to use in painting

Overrides: BaseRowDelegate._paintDefault
