<h2>Detailed Description</h2>
<p>The Q3Table class provides a flexible editable table widget.</p>
<p>Q3Table is easy to use, although it does have a large API because of the comprehensive functionality that it provides. Q3Table includes functions for manipulating <a href="#headers">headers</a>, <a href="#columnsrows">rows and columns</a>, <a href="#cells">cells</a> and <a href="#selections">selections</a>. Q3Table also provides in-place editing and drag and drop, as well as a useful set of <a href="#signals">signals</a>. Q3Table efficiently supports very large tables, for example, tables one million by one million cells are perfectly possible. Q3Table is economical with memory, using none for unused cells.</p>
<pre> Q3Table *table = new Q3Table(100, 250, this);
table->setPixmap(3, 2, pix);
table->setText(3, 2, "A pixmap");</pre>
<p>The first line constructs the table specifying its size in rows and columns. We then insert a pixmap and some text into the <i>same</i> <a href="#cells">cell</a>, with the pixmap appearing to the left of the text. Q3Table cells can be populated with <a href="q3tableitem.html">Q3TableItem</a>s, <a href="q3combotableitem.html">Q3ComboTableItem</a>s or by <a href="q3checktableitem.html">Q3CheckTableItem</a>s. By default a vertical header appears at the left of the table showing row numbers and a horizontal header appears at the top of the table showing column numbers. (The numbers displayed start at 1, although row and column numbers within Q3Table begin at 0.)</p>
<p>If you want to use mouse tracking call setMouseTracking(true) on the <i>viewport</i>.</p>
<p align="center"><img src="images/qtableitems.png" alt="Table Items" /></p><a name="headers"></a><a name="headers"></a>
<h3>Headers</h3>
<p>Q3Table supports a header column, e.g. to display row numbers, and a header row, e.g to display column titles. To set row or column labels use <a href="q3header.html#setLabel">Q3Header::setLabel</a>() on the pointers returned by <a href="q3table.html#verticalHeader">verticalHeader</a>() and <a href="q3table.html#horizontalHeader">horizontalHeader</a>() respectively. The vertical header is displayed within the table's left margin whose width is set with <a href="q3table.html#setLeftMargin">setLeftMargin</a>(). The horizontal header is displayed within the table's top margin whose height is set with <a href="q3table.html#setTopMargin">setTopMargin</a>(). The table's grid can be switched off with <a href="q3table.html#showGrid-prop">setShowGrid</a>(). If you want to hide a horizontal header call <a href="qwidget.html#hide">hide</a>(), and call setTopMargin(0) so that the area the header would have occupied is reduced to zero size.</p>
<p>Header labels are indexed via their section numbers. Note that the default behavior of <a href="q3header.html">Q3Header</a> regarding section numbers is overriden for Q3Table. See the explanation below in the Rows and Columns section in the discussion of moving columns and rows.</p>
<a name="columnsrows"></a><a name="rows-and-columns"></a>
<h3>Rows and Columns</h3>
<p>Row and column sizes are set with <a href="q3table.html#setRowHeight">setRowHeight</a>() and <a href="q3table.html#setColumnWidth">setColumnWidth</a>(). If you want a row high enough to show the tallest item in its entirety, use <a href="q3table.html#adjustRow">adjustRow</a>(). Similarly, to make a column wide enough to show the widest item use <a href="q3table.html#adjustColumn">adjustColumn</a>(). If you want the row height and column width to adjust automatically as the height and width of the table changes use <a href="q3table.html#setRowStretchable">setRowStretchable</a>() and <a href="q3table.html#setColumnStretchable">setColumnStretchable</a>().</p>
<p>Rows and columns can be hidden and shown with <a href="q3table.html#hideRow">hideRow</a>(), <a href="q3table.html#hideColumn">hideColumn</a>(), <a href="q3table.html#showRow">showRow</a>() and <a href="q3table.html#showColumn">showColumn</a>(). New rows and columns are inserted using <a href="q3table.html#insertRows">insertRows</a>() and <a href="q3table.html#insertColumns">insertColumns</a>(). Additional rows and columns are added at the bottom (rows) or right (columns) if you set <a href="q3table.html#numRows-prop">setNumRows</a>() or <a href="q3table.html#numCols-prop">setNumCols</a>() to be larger than <a href="q3table.html#numRows-prop">numRows</a>() or <a href="q3table.html#numCols-prop">numCols</a>(). Existing rows and columns are removed with <a href="q3table.html#removeRow">removeRow</a>() and <a href="q3table.html#removeColumn">removeColumn</a>(). Multiple rows and columns can be removed with <a href="q3table.html#removeRows">removeRows</a>() and <a href="q3table.html#removeColumns">removeColumns</a>().</p>
<p>Rows and columns can be set to be movable using <a href="q3table.html#rowMovingEnabled-prop">rowMovingEnabled</a>() and <a href="q3table.html#columnMovingEnabled-prop">columnMovingEnabled</a>(). The user can drag them to reorder them holding down the Ctrl key and dragging the mouse. For performance reasons, the default behavior of <a href="q3header.html">Q3Header</a> section numbers is overridden by Q3Table. Currently in Q3Table, 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 <a href="q3header.html">Q3Header</a>. The Q3Table <a href="q3header.html">Q3Header</a> classes do not provide a mechanism for indexing independently of the user interface ordering.</p>
<p>The table can be sorted using <a href="q3table.html#sortColumn">sortColumn</a>(). Users can sort a column by clicking its header if <a href="q3table.html#sorting-prop">setSorting</a>() is set to true. Rows can be swapped with <a href="q3table.html#swapRows">swapRows</a>(), columns with <a href="q3table.html#swapColumns">swapColumns</a>() and cells with <a href="q3table.html#swapCells">swapCells</a>().</p>
<p>For editable tables (see <a href="q3table.html#readOnly-prop">setReadOnly</a>()) you can set the read-only property of individual rows and columns with <a href="q3table.html#setRowReadOnly">setRowReadOnly</a>() and <a href="q3table.html#setColumnReadOnly">setColumnReadOnly</a>(). (Whether a cell is editable or read-only depends on these settings and the cell's <a href="q3tableitem.html">Q3TableItem</a>.</p>
<p>The row and column which have the focus are returned by <a href="q3table.html#currentRow">currentRow</a>() and <a href="q3table.html#currentColumn">currentColumn</a>() respectively.</p>
<p>Although many Q3Table functions operate in terms of rows and columns the <a href="q3table.html#indexOf">indexOf</a>() function returns a single integer identifying a particular cell.</p>
<a name="cells"></a><a name="cells"></a>
<h3>Cells</h3>
<p>All of a Q3Table's cells are empty when the table is constructed.</p>
<p>There are two approaches to populating the table's cells. The first and simplest approach is to use Q3TableItems or <a href="q3tableitem.html">Q3TableItem</a> subclasses. The second approach doesn't use Q3TableItems 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.</p>
<p>To put a string in a cell use <a href="q3table.html#setText">setText</a>(). This function will create a new <a href="q3tableitem.html">Q3TableItem</a> 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 <a href="qlineedit.html">QLineEdit</a>. A pixmap may be put in a cell with <a href="q3table.html#setPixmap">setPixmap</a>(), which also creates a table item if required. A cell may contain <i>both</i> a pixmap and text; the pixmap is displayed to the left of the text. Another approach is to construct a <a href="q3tableitem.html">Q3TableItem</a> or <a href="q3tableitem.html">Q3TableItem</a> subclass, set its properties, then insert it into a cell with <a href="q3table.html#setItem">setItem</a>().</p>
<p>If you want cells which contain comboboxes use the <a href="q3combotableitem.html">Q3ComboTableItem</a> class. Similarly if you require cells containing checkboxes use the <a href="q3checktableitem.html">Q3CheckTableItem</a> class. These table items look and behave just like the combobox or checkbox widgets but consume far less memory.</p>
<p>Q3Table takes ownership of its Q3TableItems and will delete them when the table itself is destroyed. You can take ownership of a table item using <a href="q3table.html#takeItem">takeItem</a>() 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, <a href="q3table.html#swapCells">swapCells</a>()).</p>
<p>In-place editing of the text in Q3TableItems, and the values in Q3ComboTableItems and Q3CheckTableItems works automatically. Cells may be editable or read-only, see <a href="q3tableitem.html#EditType-enum">Q3TableItem::EditType</a>. If you want fine control over editing see <a href="q3table.html#beginEdit">beginEdit</a>() and <a href="q3table.html#endEdit">endEdit</a>().</p>
<p>The contents of a cell can be retrieved as a <a href="q3tableitem.html">Q3TableItem</a> using <a href="q3table.html#item">item</a>(), or as a string with <a href="q3table.html#text">text</a>() or as a pixmap (if there is one) with <a href="q3table.html#pixmap">pixmap</a>(). A cell's bounding rectangle is given by <a href="q3table.html#cellGeometry">cellGeometry</a>(). Use <a href="q3table.html#updateCell">updateCell</a>() to repaint a cell, for example to clear away a cell's visual representation after it has been deleted with <a href="q3table.html#clearCell">clearCell</a>(). The table can be forced to scroll to show a particular cell with <a href="q3table.html#ensureCellVisible">ensureCellVisible</a>(). The <a href="q3table.html#isSelected">isSelected</a>() function indicates if a cell is selected.</p>
<p>It is possible to use your own widget as a cell's widget using <a href="q3table.html#setCellWidget">setCellWidget</a>(), but subclassing <a href="q3tableitem.html">Q3TableItem</a> might be a simpler approach. The cell's widget (if there is one) can be removed with <a href="q3table.html#clearCellWidget">clearCellWidget</a>().</p>
<a name="notes-on-large-tables"></a><a name="bigtables"></a><a name="large-tables"></a>
<h4>Large tables</h4>
<p>For large, sparse, tables using Q3TableItems or other widgets is inefficient. The solution is to <i>draw</i> the cell as it should appear and to create and destroy cell editors on demand.</p>
<p>This approach requires that you reimplement various functions. Reimplement <a href="q3table.html#paintCell">paintCell</a>() to display your data, and <a href="q3table.html#createEditor">createEditor</a>() and <a href="q3table.html#setCellContentFromEditor">setCellContentFromEditor</a>() to support in-place editing. It is very important to reimplement <a href="q3table.html#resizeData">resizeData</a>() to have no functionality, to prevent Q3Table from attempting to create a huge array. You will also need to reimplement <a href="q3table.html#item">item</a>(), <a href="q3table.html#setItem">setItem</a>(), <a href="q3table.html#takeItem">takeItem</a>(), <a href="q3table.html#clearCell">clearCell</a>(), and <a href="q3table.html#insertWidget">insertWidget</a>(), <a href="q3table.html#cellWidget">cellWidget</a>() and <a href="q3table.html#clearCellWidget">clearCellWidget</a>(). In almost every circumstance (for sorting, removing and inserting columns and rows, etc.), you also need to reimplement <a href="q3table.html#swapRows">swapRows</a>(), <a href="q3table.html#swapCells">swapCells</a>() and <a href="q3table.html#swapColumns">swapColumns</a>(), including header handling.</p>
<p>If you represent active cells with a dictionary of Q3TableItems and QWidgets, i.e. only store references to cells that are actually used, many of the functions can be implemented with a single line of code.</p>
<p>For more information on cells see the <a href="q3tableitem.html">Q3TableItem</a> documenation.</p>
<a name="selections"></a><a name="selections"></a>
<h3>Selections</h3>
<p>Q3Table's support single selection, multi-selection (multiple cells) or no selection. The selection mode is set with <a href="q3table.html#selectionMode-prop">setSelectionMode</a>(). Use <a href="q3table.html#isSelected">isSelected</a>() to determine if a particular cell is selected, and <a href="q3table.html#isRowSelected">isRowSelected</a>() and <a href="q3table.html#isColumnSelected">isColumnSelected</a>() to see if a row or column is selected.</p>
<p>Q3Table's support many simultaneous selections. You can programmatically select cells with <a href="q3table.html#addSelection">addSelection</a>(). The number of selections is given by <a href="q3table.html#numSelections-prop">numSelections</a>(). The current selection is returned by <a href="q3table.html#currentSelection">currentSelection</a>(). You can remove a selection with <a href="q3table.html#removeSelection">removeSelection</a>() and remove all selections with <a href="q3table.html#clearSelection">clearSelection</a>(). Selections are <a href="q3tableselection.html">Q3TableSelection</a> objects.</p>
<p>To easily add a new selection use <a href="q3table.html#selectCells">selectCells</a>(), <a href="q3table.html#selectRow">selectRow</a>() or <a href="q3table.html#selectColumn">selectColumn</a>().</p>
<p>Alternatively, use <a href="q3table.html#addSelection">addSelection</a>() to add new selections using <a href="q3tableselection.html">Q3TableSelection</a> objects. The advantage of using <a href="q3tableselection.html">Q3TableSelection</a> objects is that you can call <a href="q3tableselection.html#expandTo">Q3TableSelection::expandTo</a>() to resize the selection and can query and compare them.</p>
<p>The number of selections is given by <a href="q3table.html#numSelections-prop">numSelections</a>(). The current selection is returned by <a href="q3table.html#currentSelection">currentSelection</a>(). You can remove a selection with <a href="q3table.html#removeSelection">removeSelection</a>() and remove all selections with <a href="q3table.html#clearSelection">clearSelection</a>().</p>
<a name="signals"></a><a name="signals"></a>
<h3>Signals</h3>
<p>When the user clicks a cell the <a href="q3table.html#currentChanged">currentChanged</a>() signal is emitted. You can also connect to the lower level <a href="q3table.html#clicked">clicked</a>(), <a href="q3table.html#doubleClicked">doubleClicked</a>() and <a href="q3table.html#pressed">pressed</a>() signals. If the user changes the selection the <a href="q3table.html#selectionChanged">selectionChanged</a>() signal is emitted; similarly if the user changes a cell's value the <a href="q3table.html#valueChanged">valueChanged</a>() signal is emitted. If the user right-clicks (or presses the appropriate platform-specific key sequence) the <a href="q3table.html#contextMenuRequested">contextMenuRequested</a>() signal is emitted. If the user drops a drag and drop object the <a href="q3table.html#dropped">dropped</a>() signal is emitted with the drop event.</p>

<p>This function returns the widget which should be used as an editor for the contents of the cell at <i>row</i>, <i>col</i>.</p>
<p>If <i>initFromCell</i> is true, the editor is used to edit the current contents of the cell (so the editor widget should be initialized with this content). If <i>initFromCell</i> is false, the content of the cell is replaced with the new content which the user entered into the widget created by this function.</p>
<p>The default functionality is as follows: if <i>initFromCell</i> is true or the cell has a <a href="q3tableitem.html">Q3TableItem</a> and the table item's <a href="q3tableitem.html#isReplaceable">Q3TableItem::isReplaceable</a>() is false then the cell is asked to create an appropriate editor (using <a href="q3tableitem.html#createEditor">Q3TableItem::createEditor</a>()). Otherwise a <a href="qlineedit.html">QLineEdit</a> is used as the editor.</p>
<p>If you want to create your own editor for certain cells, implement a custom <a href="q3tableitem.html">Q3TableItem</a> subclass and reimplement <a href="q3tableitem.html#createEditor">Q3TableItem::createEditor</a>().</p>
<p>If you are not using <a href="q3tableitem.html">Q3TableItem</a>s and you don't want to use a <a href="qlineedit.html">QLineEdit</a> as the default editor, subclass <a href="q3table.html">Q3Table</a> and reimplement this function with code like this:</p>
<pre> Q3TableItem *i = item(row, col);
if (initFromCell || (i && !i->isReplaceable()))
<span class="comment">// If we had a Q3TableItem ask the base class to create the editor</span>
return Q3Table::createEditor(row, col, initFromCell);
else
return ...(create your own editor)</pre>
<p>Ownership of the editor widget is transferred to the caller.</p>
<p>If you reimplement this function return 0 for read-only cells. You will need to reimplement <a href="q3table.html#setCellContentFromEditor">setCellContentFromEditor</a>() to retrieve the data the user entered.</p>

<p>If the cell is not being edited or <i>accept</i> is false the function returns and the cell's contents are left unchanged.</p>
<p>If <i>accept</i> is true the content of the editor must be transferred to the relevant cell. If <i>replace</i> is true the current content of this cell should be replaced by the content of the editor (this means removing the current <a href="q3tableitem.html">Q3TableItem</a> of the cell and creating a new one for the cell).

<p>Paints the cell at <i>row</i>, <i>col</i> on the painter <i>p</i>. The painter has already been translated to the cell's origin. <i>cr</i> describes the cell coordinates in the content coordinate system.</p>
<p>If <i>selected</i> is true the cell is highlighted.</p>
<p><i>cg</i> is the colorgroup which should be used to draw the cell content.</p>
<p>If you want to draw custom cell content, for example right-aligned text, you must either reimplement paintCell(), or subclass <a href="q3tableitem.html">Q3TableItem</a> and reimplement <a href="q3tableitem.html#paint">Q3TableItem::paint</a>() to do the custom drawing.</p>
<p>If you're using a <a href="q3tableitem.html">Q3TableItem</a> subclass, for example, to store a data structure, then reimplementing <a href="q3tableitem.html#paint">Q3TableItem::paint</a>() may be the best approach. For data you want to draw immediately, e.g. data retrieved from a database, it is probably best to reimplement paintCell(). Note that if you reimplement paintCell(), i.e. don't use <a href="q3tableitem.html">Q3TableItem</a>s, you must reimplement other functions: see the notes on large tables.</p>
<p>Note that the painter is not clipped by default in order to get maximum efficiency. If you want clipping, use code like this:</p>
<pre> p->setClipRect(cellRect(row, col), QPainter::CoordPainter);

<h3 class="fn"><a name="swapCells"></a>void Q3Table::swapCells ( int <i>row1</i>, int <i>col1</i>, int <i>row2</i>, int <i>col2</i> ) <tt> [virtual slot]</tt></h3>
<p>Swaps the contents of the cell at <i>row1</i>, <i>col1</i> with the contents of the cell at <i>row2</i>, <i>col2</i>.</p>
<p>This function is also called when the table is sorted.</p>
<p>If you don't use <a href="q3tableitem.html">Q3TableItem</a>s and want your users to be able to swap cells, you will need to reimplement this function. (See the notes on large tables.)</p>

<h3 class="fn"><a name="swapColumns"></a>void Q3Table::swapColumns ( int <i>col1</i>, int <i>col2</i>, bool <i>swapHeader</i> = false ) <tt> [virtual slot]</tt></h3>
<p>Swaps the data in <i>col1</i> with <i>col2</i>.</p>
<p>This function is used to swap the positions of two columns. It is called when the user changes the order of columns (see <a href="q3table.html#columnMovingEnabled-prop">setColumnMovingEnabled</a>(), and when columns are sorted.</p>
<p>If you don't use <a href="q3tableitem.html">Q3TableItem</a>s and want your users to be able to swap columns you will need to reimplement this function. (See the notes on large tables.)</p>
<p>If <i>swapHeader</i> is true, the columns' header contents is also swapped.</p>

<p>Swaps the data in <i>row1</i> and <i>row2</i>.</p>
<p>This function is used to swap the positions of two rows. It is called when the user changes the order of rows (see <a href="q3table.html#rowMovingEnabled-prop">setRowMovingEnabled</a>()), and when rows are sorted.</p>
<p>If you don't use <a href="q3tableitem.html">Q3TableItem</a>s and want your users to be able to swap rows, e.g. for sorting, you will need to reimplement this function. (See the notes on large tables.)</p>
<p>If <i>swapHeader</i> is true, the rows' header contents is also swapped.</p>
<p>This function will not update the <a href="q3table.html">Q3Table</a>, you will have to do this manually, e.g. by calling <a href="q3scrollview.html#updateContents">updateContents</a>().</p>
