Returns the QModelIndex associated with the given item.

Note: In Qt versions prior to 5.10, this function took a non-const item.

Inserts an empty column into the table at column.

Inserts an empty row into the table at row.

Returns whether a persistent editor is open for item item.

See also openPersistentEditor() and closePersistentEditor().

Returns the item for the given row and column if one has been set; otherwise returns nullptr.

See also setItem().

This signal is emitted when the specified item has been activated

Returns a pointer to the item at the given point, or returns nullptr if point is not covered by an item in the table widget.

See also item().

Returns the item at the position equivalent to QPoint(ax, ay) in the table widget's coordinate system, or returns nullptr if the specified point is not covered by an item in the table widget.

See also item().

This signal is emitted whenever the data of item has changed.

This signal is emitted whenever an item in the table is clicked. The item specified is the item that was clicked.

This signal is emitted whenever an item in the table is double clicked. The item specified is the item that was double clicked.

This signal is emitted when the mouse cursor enters an item. The item is the item entered.

This signal is only emitted when mouseTracking is turned on, or when a mouse button is pressed while moving into an item.

Returns a pointer to the QTableWidgetItem associated with the given index.

This signal is emitted whenever an item in the table is pressed. The item specified is the item that was pressed.

Returns the item prototype used by the table.

See also setItemPrototype().

This signal is emitted whenever the selection changes.

See also selectedItems() and QTableWidgetItem::isSelected().

Returns a list of pointers to the items contained in the data object. If the object was not created by a QTreeWidget in the same process, the list is empty.

Returns an object that contains a serialized description of the specified items. The format used to describe the items is obtained from the mimeTypes() function.

If the list of items is empty, nullptr is returned rather than a serialized empty list.

Returns a list of MIME types that can be used to describe a list of tablewidget items.

See also mimeData().

Opens an editor for the give item. The editor remains open after editing.

See also closePersistentEditor() and isPersistentEditorOpen().

Removes the widget set on the cell indicated by row and column.

Removes the column column and all its items from the table.

Removes the row row and all its items from the table.

Returns the row for the item.

Returns the number of rows.

Note: Getter function for property rowCount.

See also setRowCount().

Scrolls the view if necessary to ensure that the item is visible. The hint parameter specifies more precisely where the item should be located after the operation.

Returns a list of all selected items.

This function returns a list of pointers to the contents of the selected cells. Use the selectedIndexes() function to retrieve the complete selection including empty cells.

See also selectedIndexes().

Returns a list of all selected ranges.

See also QTableWidgetSelectionRange.

Sets the given widget to be displayed in the cell in the given row and column, passing the ownership of the widget to the table.

If cell widget A is replaced with cell widget B, cell widget A will be deleted. For example, in the code snippet below, the QLineEdit object will be deleted.

See also cellWidget().

Sets the number of columns in this table's model to columns. If this is less than columnCount(), the data in the unwanted columns is discarded.

Note: Setter function for property columnCount.

See also columnCount() and setRowCount().

Sets the current cell to be the cell at position (row, column).

Depending on the current selection mode, the cell may also be selected.

See also setCurrentItem(), currentRow(), and currentColumn().

Sets the current cell to be the cell at position (row, column), using the given command.

See also setCurrentItem(), currentRow(), and currentColumn().

Sets the current item to item.

Unless the selection mode is NoSelection, the item is also selected.

See also currentItem() and setCurrentCell().

Sets the current item to be item, using the given command.

See also currentItem() and setCurrentCell().

Sets the horizontal header item for column column to item. If necessary, the column count is increased to fit the item. The previous header item (if there was one) is deleted.

See also horizontalHeaderItem().

Sets the horizontal header labels using labels.

Sets the item for the given row and column to item.

The table takes ownership of the item.

Note that if sorting is enabled (see sortingEnabled) and column is the current sort column, the row will be moved to the sorted position determined by item.

If you want to set several items of a particular row (say, by calling setItem() in a loop), you may want to turn off sorting before doing so, and turn it back on afterwards; this will allow you to use the same row argument for all items in the same row (i.e. setItem() will not move the row).

See also item() and takeItem().

Sets the item prototype for the table to the specified item.

The table widget will use the item prototype clone function when it needs to create a new table item. For example when the user is editing in an empty cell. This is useful when you have a QTableWidgetItem subclass and want to make sure that QTableWidget creates instances of your subclass.

The table takes ownership of the prototype.

See also itemPrototype().

Selects or deselects the range depending on select.

Sets the number of rows in this table's model to rows. If this is less than rowCount(), the data in the unwanted rows is discarded.

Note: Setter function for property rowCount.

See also rowCount() and setColumnCount().

Sets the vertical header item for row row to item.

See also verticalHeaderItem().

Sets the vertical header labels using labels.

Sorts all the rows in the table widget based on column and order.

Returns the drop actions supported by this view.

See also Qt::DropActions.

Removes the item at row and column from the table without deleting it.

Removes the vertical header item at row from the header without deleting it.

Returns the vertical header item for row row.

See also setVerticalHeaderItem().

Returns the visual column of the given logicalColumn.

Returns the rectangle on the viewport occupied by the item at item.

Returns the visual row of the given logicalRow.
