|
|
|
|
|
|
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="qcombotableitem.html">TQComboTableItem</a>s or by <a href="qchecktableitem.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="ntqwidget.html#setMouseTracking">setMouseTracking</a>( TRUE ) on
|
|
the <em>viewport</em>; (see <a href="ntqscrollview.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="ntqwidget.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="ntqlineedit.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="qcombotableitem.html">TQComboTableItem</a>
|
|
class. Similarly if you require cells containing checkboxes use
|
|
the <a href="qchecktableitem.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="qchecktableitem.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>().

|
|
<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>
|
|
This function is called to start in-place editing of the cell at

complete <a href="#endEdit">endEdit</a>() will be called to replace the cell's content
|

</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="ntqlineedit.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.

|
|
</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 );

|
|
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>() *

|
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
