TTkTable

class TTkTable(*, tableWidget: TTkTableWidget = None, tableModel: TTkAbstractTableModel = None, vSeparator: bool = True, hSeparator: bool = True, vHeader: bool = True, hHeader: bool = True, sortingEnabled=False, dataPadding=1, **kwargs)

Bases: TTkAbstractScrollArea

TTkTable is a container widget which place TTkTableWidget in a scrolling area with on-demand scroll bars.

A TTkTableWidget implements a table view that displays items from a model.

The TTkTableWidget class is one of the Model/View Classes and is part of TermTk’s model/view framework.

TTkTableWidget implements the methods to allow it to display data provided by models derived from the TTkAbstractTableModel class.

Navigation

You can navigate the cells in the table by clicking on a cell with the mouse, or by using the arrow keys, you can also hit Tab and Backtab to move from cell to cell.

Visual Appearance

The table has a vertical header that can be obtained using the verticalHeader() function, and a horizontal header that is available through the horizontalHeader() function. The height of each row in the table can be set using setRowHeight(); similarly, the width of columns can be set using setColumnWidth().

They can be selected with selectRow() and selectColumn(). The table will show a grid depending on the setHSeparatorVisibility() setVSeparatorVisibility() methods.

The items shown in a table view, like those in the other item views, are rendered and edited using standard delegates. However, for some tasks it is sometimes useful to be able to insert widgets in a table instead. Widgets are set for particular indexes with the setIndexWidget() function, and later retrieved with indexWidget().

By default, the cells in a table do not expand to fill the available space. You can make the cells fill the available space by stretching the last header section.

To distribute the available space according to the space requirement of each column or row, call the view’s resizeColumnsToContents() or resizeRowsToContents() functions.

Parameters:

tableWidget (TTkTableWidget, optional) – a custom Table Widget to be used instead of the default one.
