<hr><a name="details"></a><h2>Detailed Description</h2>
The TQComboTableItem class provides a means of using
comboboxes in TQTables.
<p>
<p> A TQComboTableItem is a table item which looks and behaves like a
combobox. The advantage of using TQComboTableItems rather than real
comboboxes is that a TQComboTableItem uses far less resources than
real comboboxes in <a href="tqtable.html">TQTable</a>s. When the cell has the focus it
displays a real combobox which the user can interact with. When
the cell does not have the focus the cell <em>looks</em> like a
combobox. Only text items (i.e. no pixmaps) may be used in
TQComboTableItems.
<p> TQComboTableItem items have the edit type <a href="tqtableitem.html#EditType-enum">WhenCurrent</a> (see
<a href="tqtableitem.html#EditType-enum">EditType</a>). The TQComboTableItem's list of items is provided by
a <a href="tqstringlist.html">TQStringList</a> passed to the constructor.
<p> The list of items may be changed using <a href="#setStringList">setStringList</a>(). The
current item can be set with <a href="#setCurrentItem">setCurrentItem</a>() and retrieved with
<a href="#currentItem">currentItem</a>(). The text of the current item can be obtained with
<a href="#currentText">currentText</a>(), and the text of a particular item can be retrieved
with <a href="#text">text</a>().
<p> If <a href="#isEditable">isEditable</a>() is TRUE the TQComboTableItem will permit the user
to either choose an existing list item, or create a new list item
by entering their own text; otherwise the user may only choose one
of the existing list items.
<p> To populate a table cell with a TQComboTableItem use
<a href="tqtable.html#setItem">TQTable::setItem</a>().
<p> TQComboTableItems may be deleted with <a href="tqtable.html#clearCell">TQTable::clearCell</a>().
<p> TQComboTableItems can be distinguished from <a href="tqtableitem.html">TQTableItem</a>s and
<a href="tqchecktableitem.html">TQCheckTableItem</a>s using their Run Time Type Identification
number (see <a href="#rtti">rtti</a>()).

<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="TQComboTableItem"></a>TQComboTableItem::TQComboTableItem ( <a href="tqtable.html">TQTable</a> * table, const <a href="tqstringlist.html">TQStringList</a> & list, bool editable = FALSE )
</h3>
Creates a combo table item for the table <em>table</em>. The combobox's
list of items is passed in the <em>list</em> argument. If <em>editable</em> is
TRUE the user may type in new list items; if <em>editable</em> is FALSE
the user may only select from the list of items provided.
<p> By default TQComboTableItems cannot be replaced by other table
items since <a href="tqtableitem.html#isReplaceable">isReplaceable</a>() returns FALSE by default.
<p> <p>See also <a href="tqtable.html#clearCell">TQTable::clearCell</a>() and <a href="tqtableitem.html#EditType-enum">EditType</a>.
<h3 class=fn><a name="~TQComboTableItem"></a>TQComboTableItem::~TQComboTableItem ()
</h3>
TQComboTableItem destructor.
<h3 class=fn>int <a name="count"></a>TQComboTableItem::count () const
</h3>
Returns the total number of list items in the combo table item.
<h3 class=fn>int <a name="currentItem"></a>TQComboTableItem::currentItem () const
</h3>
Returns the index of the combo table item's current list item.
<p> <p>See also <a href="#setCurrentItem">setCurrentItem</a>().
<h3 class=fn><a href="tqstring.html">TQString</a> <a name="currentText"></a>TQComboTableItem::currentText () const
</h3>
Returns the text of the combo table item's current list item.
<p> <p>See also <a href="#currentItem">currentItem</a>() and <a href="#text">text</a>().
<h3 class=fn>bool <a name="isEditable"></a>TQComboTableItem::isEditable () const
</h3>
Returns TRUE if the user can add their own list items to the
combobox's list of items; otherwise returns FALSE.
<p> <p>See also <a href="#setEditable">setEditable</a>().
<h3 class=fn>int <a name="rtti"></a>TQComboTableItem::rtti () const<tt> [virtual]</tt>
</h3>
<p> Returns 1.
<p> Make your derived classes return their own values for <a href="#rtti">rtti</a>()to
distinguish between different table item subclasses. You should
use values greater than 1000, preferably a large random number, to
allow for extensions to this class.
<p> <p>See also <a href="tqtableitem.html#rtti">TQTableItem::rtti</a>().
<p>Reimplemented from <a href="tqtableitem.html#rtti">TQTableItem</a>.
<h3 class=fn>void <a name="setCurrentItem"></a>TQComboTableItem::setCurrentItem ( int i )<tt> [virtual]</tt>
</h3>
Sets the list item <em>i</em> to be the combo table item's current list
item.
<p> <p>See also <a href="#currentItem">currentItem</a>().
<p>Example: <a href="small-table-example-example.html#x2797">table/small-table-demo/main.cpp</a>.
<h3 class=fn>void <a name="setCurrentItem-2"></a>TQComboTableItem::setCurrentItem ( const <a href="tqstring.html">TQString</a> & s )<tt> [virtual]</tt>
</h3>
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
<p> Sets the list item whose text is <em>s</em> to be the combo table item's
current list item. Does nothing if no list item has the text <em>s</em>.
<p> <p>See also <a href="#currentItem">currentItem</a>().
<h3 class=fn>void <a name="setEditable"></a>TQComboTableItem::setEditable ( bool b )<tt> [virtual]</tt>
</h3>
If <em>b</em> is TRUE the combo table item can be edited, i.e. the user
may enter a new text item themselves. If <em>b</em> is FALSE the user may
may only choose one of the existing items.
<p> <p>See also <a href="#isEditable">isEditable</a>().
<h3 class=fn>void <a name="setStringList"></a>TQComboTableItem::setStringList ( const <a href="tqstringlist.html">TQStringList</a> & l )<tt> [virtual]</tt>
</h3>
Sets the list items of this TQComboTableItem to the strings in the
string list <em>l</em>.
<h3 class=fn><a href="tqstring.html">TQString</a> <a name="text"></a>TQComboTableItem::text ( int i ) const
</h3>
Returns the text of the combo's list item at index <em>i</em>.
<p> <p>See also <a href="#currentText">currentText</a>().
