In situations where you need + to create very large tables you may prefer an alternative approach + to using TQTableItems: see the notes on large tables. + + A TQTableItem contains a cell's data, by default, a string and a + pixmap. The table item also holds the cell's display size and how + the data should be aligned. The table item specifies the cell's + \l EditType and the editor used for in-place editing (by default a + TQLineEdit). If you want checkboxes use \l{TQCheckTableItem}, and if + you want comboboxes use \l{TQComboTableItem}. The \l EditType (set + in the constructor) determines whether the cell's contents may be + edited. + + If a pixmap is specified it is displayed to the left of any text. + You can change the text or pixmap with setText() and setPixmap() + respectively. For text you can use setWordWrap(). + + When sorting table items the key() function is used; by default + this returns the table item's text(). Reimplement key() to + customize how your table items will sort. + + Table items are inserted into a table using TQTable::setItem(). If + you insert an item into a cell that already contains a table item + the original item will be deleted. + + Example: + \code + for ( int row = 0; row < table->numRows(); row++ ) { + for ( int col = 0; col < table->numCols(); col++ ) { + table->setItem( row, col, + new TQTableItem( table, TQTableItem::WhenCurrent, TQString::number( row * col ) ) ); + } + } + \endcode + + You can move a table item from one cell to another, in the same or + a different table, using TQTable::takeItem() and TQTable::setItem() + but see also TQTable::swapCells(). + + Table items can be deleted with delete in the standard way; the + table and cell will be updated accordingly. + + Note, that if you have a table item that is not currently in a table + then anything you do to that item other than insert it into a table + will result in undefined behaviour. + + Reimplement createEditor() and setContentFromEditor() if you want + to use your own widget instead of a TQLineEdit for editing cell + contents. Reimplement paint() if you want to display custom + content. + + It is important to ensure that your custom widget can accept the + keyboard focus, so that the user can use the tab key to navigate the + table as normal. Therefore, if the widget returned by createEditor() + does not itself accept the keyboard focus, it is necessary to + nominate a child widget to do so on its behalf. For example, a + TQHBox with two child TQLineEdit widgets may use one of them to + accept the keyboard focus: + + \code + TQWidget* MyTableItem::createEditor() const + { + TQHBox* hbox = new TQHBox( table()->viewport() ); + hbox->setFocusProxy(new TQLineEdit( hbox )); + new TQLineEdit( hbox ); + return hbox; + } + \endcode + + By default, table items may be replaced by new TQTableItems + during the lifetime of a TQTable. Therefore, if you create your + own subclass of TQTableItem, and you want to ensure that + this does not happen, you must call setReplaceable(FALSE) + in the constructor of your subclass. + + \img tqtableitems.png Table Items + + \sa TQCheckTableItem TQComboTableItem + +*/ + +/*! + \fn TQTable *TQTableItem::table() const + + Returns the TQTable the table item belongs to. + + \sa TQTable::setItem() TQTableItem() +*/ + +/*! + \enum TQTableItem::EditType + + \target wheneditable + This enum is used to define whether a cell is editable or + read-only (in conjunction with other settings), and how the cell + should be displayed. + + \value Always + The cell always \e looks editable. + + Using this EditType ensures that the editor created with + createEditor() (by default a TQLineEdit) is always visible.

The horizontal header is displayed + within the table's top margin whose height is set with + setTopMargin(). The table's grid can be switched off with + setShowGrid(). If you want to hide a horizontal header call + hide(), and call setTopMargin( 0 ) so that the area the header + would have occupied is reduced to zero size. + + Header labels are indexed via their section numbers. Note that the + default behavior of TQHeader regarding section numbers is overriden + for TQTable. See the explanation below in the Rows and Columns + section in the discussion of moving columns and rows. + + \target columnsrows + \section1 Rows and Columns + + Row and column sizes are set with setRowHeight() and + setColumnWidth(). If you want a row high enough to show the + tallest item in its entirety, use adjustRow(). Similarly, to make + a column wide enough to show the widest item use adjustColumn(). + If you want the row height and column width to adjust + automatically as the height and width of the table changes use + setRowStretchable() and setColumnStretchable(). + + Rows and columns can be hidden and shown with hideRow(), + hideColumn(), showRow() and showColumn(). New rows and columns are + inserted using insertRows() and insertColumns(). Additional rows + and columns are added at the bottom (rows) or right (columns) if + you set setNumRows() or setNumCols() to be larger than numRows() + or numCols(). Existing rows and columns are removed with + removeRow() and removeColumn(). Multiple rows and columns can be + removed with removeRows() and removeColumns(). + + Rows and columns can be set to be moveable using + rowMovingEnabled() and columnMovingEnabled(). The user can drag + them to reorder them holding down the Ctrl key and dragging the + mouse. For performance reasons, the default behavior of TQHeader + section numbers is overridden by TQTable. Currently in TQTable, when + a row or column is dragged and reordered, the section number is + also changed to its new position. Therefore, there is no + difference between the section and the index fields in TQHeader. + The TQTable TQHeader classes do not provide a mechanism for indexing + independently of the user interface ordering. + + The table can be sorted using sortColumn(). Users can sort a + column by clicking its header if setSorting() is set to TRUE. Rows + can be swapped with swapRows(), columns with swapColumns() and + cells with swapCells(). + + For editable tables (see setReadOnly()) you can set the read-only + property of individual rows and columns with setRowReadOnly() and + setColumnReadOnly(). (Whether a cell is editable or read-only + depends on these settings and the cell's \link + tqtableitem.html#wheneditable TQTableItem::EditType\endlink.) + + The row and column which have the focus are returned by + currentRow() and currentColumn() respectively. + + Although many TQTable functions operate in terms of rows and + columns the indexOf() function returns a single integer + identifying a particular cell. + + \target cells + \section1 Cells + + All of a TQTable's cells are empty when the table is constructed. + + There are two approaches to populating the table's cells. The + first and simplest approach is to use TQTableItems or TQTableItem + subclasses. The second approach doesn't use TQTableItems at all + which is useful for very large sparse tables but requires you to + reimplement a number of functions. We'll look at each approach in + turn. + + To put a string in a cell use setText(). This function will create + a new TQTableItem for the cell if one doesn't already exist, and + displays the text in it. By default the table item's widget will + be a TQLineEdit. A pixmap may be put in a cell with setPixmap(), + which also creates a table item if required. A cell may contain \e + both a pixmap and text; the pixmap is displayed to the left of the + text. Another approach is to construct a TQTableItem or TQTableItem + subclass, set its properties, then insert it into a cell with + setItem(). + + If you want cells which contain comboboxes use the TQComboTableItem + class. Similarly if you require cells containing checkboxes use + the TQCheckTableItem class. These table items look and behave just + like the combobox or checkbox widgets but consume far less memory. + + \quotefile table/small-table-demo/main.cpp + \skipto int j + \printuntil TQCheckTableItem + In the example above we create a column of TQCheckTableItems and + insert them into the table using setItem(). + + TQTable takes ownership of its TQTableItems and will delete them + when the table itself is destroyed. You can take ownership of a + table item using takeItem() which you use to move a cell's + contents from one cell to another, either within the same table, + or from one table to another. (See also, swapCells()). + + In-place editing of the text in TQTableItems, and the values in + TQComboTableItems and TQCheckTableItems works automatically. Cells + may be editable or read-only, see \link + tqtableitem.html#wheneditable TQTableItem::EditType\endlink. If you + want fine control over editing see beginEdit() and endEdit(). + + The contents of a cell can be retrieved as a TQTableItem using + item(), or as a string with text() or as a pixmap (if there is + one) with pixmap(). A cell's bounding rectangle is given by + cellGeometry(). Use updateCell() to repaint a cell, for example to + clear away a cell's visual representation after it has been + deleted with clearCell(). The table can be forced to scroll to + show a particular cell with ensureCellVisible(). The isSelected() + function indicates if a cell is selected. + + It is possible to use your own widget as a cell's widget using + setCellWidget(), but subclassing TQTableItem might be a simpler + approach. The cell's widget (if there is one) can be removed with + clearCellWidget(). + + \keyword notes on large tables + \target bigtables + \section2 Large tables + + For large, sparse, tables using TQTableItems or other widgets is + inefficient. The solution is to \e draw the cell as it should + appear and to create and destroy cell editors on demand. + + This approach requires that you reimplement various functions. + Reimplement paintCell() to display your data, and createEditor() + and setCellContentFromEditor() to support in-place editing. It + is very important to reimplement resizeData() to have no + functionality, to prevent TQTable from attempting to create a huge + array. You will also need to reimplement item(), setItem(), + takeItem(), clearCell(), and insertWidget(), cellWidget() and + clearCellWidget(). In almost every circumstance (for sorting, + removing and inserting columns and rows, etc.), you also need + to reimplement swapRows(), swapCells() and swapColumns(), including + header handling. + + If you represent active cells with a dictionary of TQTableItems and + TQWidgets, i.e. only store references to cells that are actually + used, many of the functions can be implemented with a single line + of code. (See the \l table/bigtable/main.cpp example.) + + For more information on cells see the TQTableItem documenation. + + \target selections + \section1 Selections + + TQTable's support single selection, multi-selection (multiple + cells) or no selection. The selection mode is set with + setSelectionMode(). Use isSelected() to determine if a particular + cell is selected, and isRowSelected() and isColumnSelected() to + see if a row or column is selected. + + TQTable's support many simultaneous selections. You can + programmatically select cells with addSelection(). The number of + selections is given by numSelections(). The current selection is + returned by currentSelection(). You can remove a selection with + removeSelection() and remove all selections with + clearSelection(). Selections are TQTableSelection objects. + + To easily add a new selection use selectCells(), selectRow() or + selectColumn(). + + Alternatively, use addSelection() to add new selections using + TQTableSelection objects. The advantage of using TQTableSelection + objects is that you can call TQTableSelection::expandTo() to resize + the selection and can query and compare them. + + The number of selections is given by numSelections(). The current + selection is returned by currentSelection(). You can remove a + selection with removeSelection() and remove all selections with + clearSelection(). + + \target signals + \section1 Signals + + When the user clicks a cell the currentChanged() signal is + emitted.
