<hr><a name="details"></a><h2>Detailed Description</h2>
The TQTable class provides a flexible editable table widget.
<p>
<p> TQTable is easy to use, although it does have a large API because
of the comprehensive functionality that it provides. TQTable
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>. TQTable also provides in-place editing and
<a href="dnd.html">drag and drop</a>, as well as a useful set of
<a href="#signals">signals</a>. TQTable efficiently supports very
large tables, for example, tables one million by one million cells
are perfectly possible. TQTable is economical with memory, using
none for unused cells.
<p> <pre>
TQTable *table = new TQTable( 100, 250, this );
table-><a href="#setPixmap">setPixmap</a>( 3, 2, pix );
table-><a href="#setText">setText</a>( 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 <em>same</em> <a href="#cells">cell</a>, with the pixmap appearing to the
left of the text. TQTable cells can be populated with
<a href="qtableitem.html">TQTableItem</a>s, <a href="tqcombotableitem.html">TQComboTableItem</a>s or by <a href="tqchecktableitem.html">TQCheckTableItem</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 TQTable begin at 0.)
<p> If you want to use mouse tracking call <a href="tqwidget.html#setMouseTracking">setMouseTracking</a>( TRUE ) on
the <em>viewport</em>; (see <a href="tqscrollview.html#allviews">TQScrollView</a>).
<p> <center><img src="qtableitems.png" alt="Table Items"></center>
<p> <a name="headers"></a>
<h3> Headers
</h3>
<a name="1"></a><p> TQTable 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="ntqheader.html#setLabel">TQHeader::setLabel</a>() on the pointers returned by
<a href="#verticalHeader">verticalHeader</a>() and <a href="#horizontalHeader">horizontalHeader</a>() respectively. The vertical
header is displayed within the table's left margin whose width is
set with <a href="#setLeftMargin">setLeftMargin</a>(). The horizontal header is displayed
within the table's top margin whose height is set with
<a href="#setTopMargin">setTopMargin</a>(). The table's grid can be switched off with
<a href="#setShowGrid">setShowGrid</a>(). If you want to hide a horizontal header call
<a href="tqwidget.html#hide">hide</a>(), and call setTopMargin( 0 ) so that the area the header
would have occupied is reduced to zero size.
<p> Header labels are indexed via their section numbers. Note that the
default behavior of <a href="ntqheader.html">TQHeader</a> 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.
<p> <a name="columnsrows"></a>
<h3> Rows and Columns
</h3>
<a name="1-1"></a><p> Row and column sizes are set with <a href="#setRowHeight">setRowHeight</a>() and
<a href="#setColumnWidth">setColumnWidth</a>(). If you want a row high enough to show the
tallest item in its entirety, use <a href="#adjustRow">adjustRow</a>(). Similarly, to make
a column wide enough to show the widest item use <a href="#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="#setRowStretchable">setRowStretchable</a>() and <a href="#setColumnStretchable">setColumnStretchable</a>().
<p> Rows and columns can be hidden and shown with <a href="#hideRow">hideRow</a>(),
<a href="#hideColumn">hideColumn</a>(), <a href="#showRow">showRow</a>() and <a href="#showColumn">showColumn</a>(). New rows and columns are
inserted using <a href="#insertRows">insertRows</a>() and <a href="#insertColumns">insertColumns</a>(). Additional rows
and columns are added at the bottom (rows) or right (columns) if
you set <a href="#setNumRows">setNumRows</a>() or <a href="#setNumCols">setNumCols</a>() to be larger than <a href="#numRows">numRows</a>()
or <a href="#numCols">numCols</a>(). Existing rows and columns are removed with
<a href="#removeRow">removeRow</a>() and <a href="#removeColumn">removeColumn</a>(). Multiple rows and columns can be
removed with <a href="#removeRows">removeRows</a>() and <a href="#removeColumns">removeColumns</a>().
<p> Rows and columns can be set to be moveable using
<a href="#rowMovingEnabled">rowMovingEnabled</a>() and <a href="#columnMovingEnabled">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="ntqheader.html">TQHeader</a>
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.
<p> The table can be sorted using <a href="#sortColumn">sortColumn</a>(). Users can sort a
column by clicking its header if <a href="#setSorting">setSorting</a>() is set to TRUE. Rows
can be swapped with <a href="#swapRows">swapRows</a>(), columns with <a href="#swapColumns">swapColumns</a>() and
cells with <a href="#swapCells">swapCells</a>().
<p> For editable tables (see <a href="#setReadOnly">setReadOnly</a>()) you can set the read-only
property of individual rows and columns with <a href="#setRowReadOnly">setRowReadOnly</a>() and
<a href="#setColumnReadOnly">setColumnReadOnly</a>(). (Whether a cell is editable or read-only
depends on these settings and the cell's <a href="qtableitem.html#wheneditable">TQTableItem::EditType</a>.)
<p> The row and column which have the focus are returned by
<a href="#currentRow">currentRow</a>() and <a href="#currentColumn">currentColumn</a>() respectively.
<p> Although many TQTable functions operate in terms of rows and
columns the <a href="#indexOf">indexOf</a>() function returns a single integer
identifying a particular cell.
<p> <a name="cells"></a>
<h3> Cells
</h3>
<a name="1-2"></a><p> All of a TQTable's cells are empty when the table is constructed.
<p> There are two approaches to populating the table's cells. The
first and simplest approach is to use TQTableItems or <a href="qtableitem.html">TQTableItem</a>
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.
<p> To put a string in a cell use <a href="#setText">setText</a>(). 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 <a href="tqlineedit.html">TQLineEdit</a>. A pixmap may be put in a cell with <a href="#setPixmap">setPixmap</a>(),
which also creates a table item if required. A cell may contain <em>both</em> 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
<a href="#setItem">setItem</a>().
<p> If you want cells which contain comboboxes use the <a href="tqcombotableitem.html">TQComboTableItem</a>
class. Similarly if you require cells containing checkboxes use
the <a href="tqchecktableitem.html">TQCheckTableItem</a> class. These table items look and behave just
like the combobox or checkbox widgets but consume far less memory.
<p>
<pre> for ( int j = 0; j < numRows; ++j )
<a name="x2445"></a> table.<a href="#setItem">setItem</a>( j, 1, new <a href="tqchecktableitem.html">TQCheckTableItem</a>( &table, "Check me" ) );
</pre>In the example above we create a column of TQCheckTableItems and
insert them into the table using setItem().
<p> 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 <a href="#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="#swapCells">swapCells</a>()).
<p> 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 <a href="qtableitem.html#wheneditable">TQTableItem::EditType</a>. If you
want fine control over editing see <a href="#beginEdit">beginEdit</a>() and <a href="#endEdit">endEdit</a>().
<p> The contents of a cell can be retrieved as a <a href="qtableitem.html">TQTableItem</a> using
<a href="#item">item</a>(), or as a string with <a href="#text">text</a>() or as a pixmap (if there is
one) with <a href="#pixmap">pixmap</a>(). A cell's bounding rectangle is given by
<a href="#cellGeometry">cellGeometry</a>(). Use <a href="#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="#clearCell">clearCell</a>(). The table can be forced to scroll to
show a particular cell with <a href="#ensureCellVisible">ensureCellVisible</a>(). The <a href="#isSelected">isSelected</a>()
function indicates if a cell is selected.
<p> It is possible to use your own widget as a cell's widget using
<a href="#setCellWidget">setCellWidget</a>(), but subclassing TQTableItem might be a simpler
approach. The cell's widget (if there is one) can be removed with
<a href="#clearCellWidget">clearCellWidget</a>().
<p> <!-- index notes on large tables --><a name="notes-on-large-tables"></a><a name="bigtables"></a>
<h4> Large tables
</h4>
<a name="1-2-1"></a><p> For large, sparse, tables using TQTableItems or other widgets is
inefficient. The solution is to <em>draw</em> the cell as it should
appear and to create and destroy cell editors on demand.
<p> This approach requires that you reimplement various functions.
Reimplement <a href="#paintCell">paintCell</a>() to display your data, and <a href="#createEditor">createEditor</a>()
and <a href="#setCellContentFromEditor">setCellContentFromEditor</a>() to support in-place editing. It
is very important to reimplement <a href="#resizeData">resizeData</a>() to have no
functionality, to prevent TQTable from attempting to create a huge
array. You will also need to reimplement <a href="#item">item</a>(), <a href="#setItem">setItem</a>(),
<a href="#takeItem">takeItem</a>(), <a href="#clearCell">clearCell</a>(), and <a href="#insertWidget">insertWidget</a>(), <a href="#cellWidget">cellWidget</a>() and
<a href="#clearCellWidget">clearCellWidget</a>(). In almost every circumstance (for sorting,
removing and inserting columns and rows, etc.), you also need
to reimplement <a href="#swapRows">swapRows</a>(), <a href="#swapCells">swapCells</a>() and <a href="#swapColumns">swapColumns</a>(), including
header handling.
<p> 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 <a href="table-bigtable-main-cpp.html">table/bigtable/main.cpp</a> example.)
<p> For more information on cells see the <a href="qtableitem.html">TQTableItem</a> documenation.
<p> <a name="selections"></a>
<h3> Selections
</h3>
<a name="1-3"></a><p> TQTable's support single selection, multi-selection (multiple
cells) or no selection. The selection mode is set with
<a href="#setSelectionMode">setSelectionMode</a>(). Use <a href="#isSelected">isSelected</a>() to determine if a particular
cell is selected, and <a href="#isRowSelected">isRowSelected</a>() and <a href="#isColumnSelected">isColumnSelected</a>() to
see if a row or column is selected.
<p> TQTable's support many simultaneous selections. You can
programmatically select cells with <a href="#addSelection">addSelection</a>(). The number of
selections is given by <a href="#numSelections">numSelections</a>(). The current selection is
returned by <a href="#currentSelection">currentSelection</a>(). You can remove a selection with
<a href="#removeSelection">removeSelection</a>() and remove all selections with
<a href="#clearSelection">clearSelection</a>(). Selections are <a href="qtableselection.html">TQTableSelection</a> objects.
<p> To easily add a new selection use <a href="#selectCells">selectCells</a>(), <a href="#selectRow">selectRow</a>() or
<a href="#selectColumn">selectColumn</a>().
<p> Alternatively, use addSelection() to add new selections using
TQTableSelection objects. The advantage of using TQTableSelection
objects is that you can call <a href="qtableselection.html#expandTo">TQTableSelection::expandTo</a>() to resize
the selection and can query and compare them.
<p> 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().
<p> <a name="signals"></a>
<h3> Signals
</h3>
<a name="1-4"></a><p> When the user clicks a cell the <a href="#currentChanged">currentChanged</a>() signal is
emitted. You can also connect to the lower level <a href="#clicked">clicked</a>(),
<a href="#doubleClicked">doubleClicked</a>() and <a href="#pressed">pressed</a>() signals. If the user changes the
selection the <a href="#selectionChanged">selectionChanged</a>() signal is emitted; similarly if
the user changes a cell's value the <a href="#valueChanged">valueChanged</a>() signal is
emitted. If the user right-clicks (or presses the appropriate
platform-specific key sequence) the <a href="#contextMenuRequested">contextMenuRequested</a>() signal
is emitted. If the user drops a drag and drop object the <a href="#dropped">dropped</a>()
signal is emitted with the drop event.

<h3 class=fn><a href="tqwidget.html">TQWidget</a> * <a name="createEditor"></a>TQTable::createEditor ( int row, int col, bool initFromCell ) const<tt> [virtual protected]</tt>
</h3>
This function returns the widget which should be used as an editor
for the contents of the cell at <em>row</em>, <em>col</em>.
<p> If <em>initFromCell</em> 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 <em>initFromCell</em> 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> The default functionality is as follows: if <em>initFromCell</em> is
TRUE or the cell has a <a href="qtableitem.html">TQTableItem</a> and the table item's
<a href="qtableitem.html#isReplaceable">TQTableItem::isReplaceable</a>() is FALSE then the cell is asked to
create an appropriate editor (using <a href="qtableitem.html#createEditor">TQTableItem::createEditor</a>()).
Otherwise a <a href="tqlineedit.html">TQLineEdit</a> is used as the editor.
<p> If you want to create your own editor for certain cells, implement
a custom TQTableItem subclass and reimplement
TQTableItem::createEditor().
<p> If you are not using <a href="qtableitem.html">TQTableItem</a>s and you don't want to use a
TQLineEdit as the default editor, subclass TQTable and reimplement
this function with code like this:
<pre>
<a href="qtableitem.html">TQTableItem</a> *i = <a href="#item">item</a>( row, col );
if ( initFromCell || ( i && !i-><a href="qtableitem.html#isReplaceable">isReplaceable</a>() ) )
// If we had a TQTableItem ask the base class to create the editor
return TQTable::createEditor( row, col, initFromCell );
else
return ...(create your own editor)
</pre>
Ownership of the editor widget is transferred to the caller.
<p> If you reimplement this function return 0 for read-only cells. You
will need to reimplement <a href="#setCellContentFromEditor">setCellContentFromEditor</a>() to retrieve
the data the user entered.
<p> <p>See also <a href="qtableitem.html#createEditor">TQTableItem::createEditor</a>().

</h3>
Paints the cell at <em>row</em>, <em>col</em> on the painter <em>p</em>. The painter
has already been translated to the cell's origin. <em>cr</em> describes
the cell coordinates in the content coordinate system.
<p> If <em>selected</em> is TRUE the cell is highlighted.
<p> <em>cg</em> is the colorgroup which should be used to draw the cell
content.
<p> If you want to draw custom cell content, for example right-aligned
text, you must either reimplement <a href="#paintCell">paintCell</a>(), or subclass
<a href="qtableitem.html">TQTableItem</a> and reimplement <a href="qtableitem.html#paint">TQTableItem::paint</a>() to do the custom
drawing.
<p> If you're using a TQTableItem subclass, for example, to store a
data structure, then reimplementing TQTableItem::paint() 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="qtableitem.html">TQTableItem</a>s, you must reimplement other functions: see the
<a href="ntqtable.html#notes-on-large-tables">notes on large tables</a>.
<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( <a href="#cellRect">cellRect</a>(row, col), TQPainter::CoordPainter );
//... your drawing code
p->setClipping( FALSE );

<h3 class=fn>void <a name="setCellContentFromEditor"></a>TQTable::setCellContentFromEditor ( int row, int col )<tt> [virtual protected]</tt>
</h3>
This function is called to replace the contents of the cell at <em>row</em>, <em>col</em> with the contents of the cell's editor.
<p> If there already exists a <a href="qtableitem.html">TQTableItem</a> for the cell,
it calls <a href="qtableitem.html#setContentFromEditor">TQTableItem::setContentFromEditor</a>() on this TQTableItem.
<p> If, for example, you want to create different <a href="qtableitem.html">TQTableItem</a>s
depending on the contents of the editor, you might reimplement
this function.
<p> If you want to work without <a href="qtableitem.html">TQTableItem</a>s, you will need to
reimplement this function to save the data the user entered into
your data structure. (See the <a href="ntqtable.html#notes-on-large-tables">notes on large tables</a>.)
<p> <p>See also <a href="qtableitem.html#setContentFromEditor">TQTableItem::setContentFromEditor</a>() and <a href="#createEditor">createEditor</a>().
<h3 class=fn>void <a name="setCellWidget"></a>TQTable::setCellWidget ( int row, int col, <a href="tqwidget.html">TQWidget</a> * e )<tt> [virtual]</tt>
</h3>
Sets the widget <em>e</em> to the cell at <em>row</em>, <em>col</em> and takes care of
placing and resizing the widget when the cell geometry changes.
<p> By default widgets are inserted into a vector with <a href="#numRows">numRows</a>() *
<a href="#numCols">numCols</a>() elements. In very large tables you will probably want to
store the widgets in a data structure that consumes less memory (see
the <a href="ntqtable.html#notes-on-large-tables">notes on large tables</a>). To support the use of your own data
structure this function calls <a href="#insertWidget">insertWidget</a>() to add the widget to
the internal data structure. To use your own data structure
reimplement insertWidget(), <a href="#cellWidget">cellWidget</a>() and <a href="#clearCellWidget">clearCellWidget</a>().
<p> Cell widgets are created dynamically with the <tt>new</tt> operator. The
cell widgets are destroyed automatically once the table is
destroyed; the table takes ownership of the widget when using
setCellWidget.

</h3>
If <em>ro</em> is TRUE, column <em>col</em> is set to be read-only; otherwise
the column is set to be editable.
<p> Whether a cell in this column is editable or read-only depends on
the cell's EditType, and this setting:

column <em>col</em>, and repaints the cell. If a table item already
exists in this cell it is deleted and replaced with <em>item</em>. The
table takes ownership of the table item.
<p> If you don't use <a href="qtableitem.html">TQTableItem</a>s you may need to reimplement this
