Qgrid API Documentation

Qgrid is an Jupyter notebook widget which uses SlickGrid to render pandas DataFrames as interactive grid controls.

qgrid Module

class qgrid.QgridWidget(df=None, grid_options=None, precision=None, show_toolbar=None)

The widget class which is instantiated by the ‘show_grid’ method, and can also be constructed directly. All of the parameters listed below can be read/updated after instantiation via attributes of the same name as the parameter (since they’re implemented as traitlets).

When new values are set for any of these options after instantiation (such as df, grid_options, etc), the change takes effect immediately by regenerating the SlickGrid control.

Parameters:
  • df (DataFrame) – The DataFrame that will be displayed by this instance of QgridWidget.
  • grid_options (dict) – Options to use when creating the SlickGrid control (i.e. the interactive grid). See the Notes section below for more information on the available options, as well as the default options that this widget uses.
  • precision (integer) – The number of digits of precision to display for floating-point values. If unset, we use the value of pandas.get_option(‘display.precision’).
  • show_toolbar (bool) – Whether to show a toolbar with options for adding/removing rows. Adding/removing rows is an experimental feature which only works with DataFrames that have an integer index.

Notes

The following dictionary is used for grid_options if none are provided explicitly:

{
    'fullWidthRows': True,
    'syncColumnCellResize': True,
    'forceFitColumns': True,
    'rowHeight': 28,
    'enableColumnReorder': False,
    'enableTextSelectionOnCells': True,
    'editable': True,
    'autoEdit': False
}

See the SlickGrid documentation for information about these options.

See also

set_defaults
Permanently set global defaults for the parameters of the QgridWidget constructor, with the exception of the df parameter.
set_grid_option
Permanently set global defaults for individual SlickGrid options. Does so by changing the default for the grid_options parameter of the QgridWidget constructor.
df

DataFrame – Get/set the DataFrame that’s being displayed by the current instance. This DataFrame will NOT reflect any sorting/filtering/editing changes that are made via the UI. To get a copy of the DataFrame that does reflect sorting/filtering/editing changes, use the get_changed_df() method.

grid_options

dict – Get/set the SlickGrid options being used by the current instance.

precision

integer – Get/set the precision options being used by the current instance.

show_toolbar

bool – Get/set the show_toolbar option being used by the current instance.

add_row()

Append a row at the end of the dataframe by duplicating the last row and incrementing it’s index by 1. The feature is only available for DataFrames that have an integer index.

get_changed_df()

Get a copy of the DataFrame that was used to create the current instance of QgridWidget which reflects the current state of the UI. This includes any sorting or filtering changes, as well as edits that have been made by double clicking cells.

Return type:DataFrame
get_selected_rows()

Get the currently selected rows.

Return type:List of integers
remove_row()

Remove the current row from the table.

qgrid.enable(dataframe=True, series=True)

Automatically use qgrid to display all DataFrames and/or Series instances in the notebook.

Parameters:
  • dataframe (bool) – Whether to automatically use qgrid to display DataFrames instances.
  • series (bool) – Whether to automatically use qgrid to display Series instances.
qgrid.disable()

Stop using qgrid to display DataFrames and Series instances in the notebook. This has the same effect as calling enable with both kwargs set to False (and in fact, that’s what this function does internally).

qgrid.set_defaults(show_toolbar=None, precision=None, grid_options=None)

Set the default qgrid options. The options that you can set here are the same ones that you can pass into QgridWidget constructor, with the exception of the df option, for which a default value wouldn’t be particularly useful (since the purpose of qgrid is to display a DataFrame).

See the documentation for QgridWidget for more information.

Notes

This function will be useful to you if you find yourself setting the same options every time you create a QgridWidget. Calling this set_defaults function once sets the options for the lifetime of the kernel, so you won’t have to include the same options every time you instantiate a QgridWidget.

See also

QgridWidget()
The widget whose default behavior is changed by set_defaults.
qgrid.set_grid_option(optname, optvalue)

Set the default value for one of the options that gets passed into the SlickGrid constructor.

Parameters:
  • optname (str) – The name of the option to set.
  • optvalue (object) – The new value to set.

Notes

The options you can set here are the same ones that you can set via the grid_options parameter of the set_defaults or show_grid functions. See the SlickGrid documentation for the full list of available options.

qgrid.show_grid(data_frame, show_toolbar=None, precision=None, grid_options=None)

Renders a DataFrame or Series as an interactive qgrid, represented by an instance of the QgridWidget class. The QgridWidget instance is constructed using the options passed in to this function. The data_frame argument to this function is used as the df kwarg in call to the QgridWidget constructor, and the rest of the parameters are passed through as is.

If the data_frame argument is a Series, it will be converted to a DataFrame before being passed in to the QgridWidget constructor as the df kwarg.

See the QgridWidget documentation for descriptions of all of the options that can be set via it’s constructor.

Return type:QgridWidget
