The advantage of using TQComboTableItems rather than real comboboxes is that a TQComboTableItem uses far less resources than real comboboxes in <a href="ntqtable.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="qtableitem.html#EditType-enum">WhenCurrent</a> (see <a href="qtableitem.html#EditType-enum">EditType</a>). The TQComboTableItem's list of items is provided by a <a href="ntqstringlist.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="ntqtable.html#setItem">TQTable::setItem</a>(). <p> TQComboTableItems may be deleted with <a href="ntqtable.html#clearCell">TQTable::clearCell</a>(). <p> TQComboTableItems can be distinguished from <a href="qtableitem.html">TQTableItem</a>s and <a href="qchecktableitem.html">TQCheckTableItem</a>s using their Run Time Type Identification number (see <a href="#rtti">rtti</a>()). <p> <center><img src="qtableitems.png" alt="Table Items"></center> <p> <p>See also <a href="qchecktableitem.html">TQCheckTableItem</a>, <a href="qtableitem.html">TQTableItem</a>, <a href="ntqcombobox.html">TQComboBox</a>, and <a href="advanced.html">Advanced Widgets</a>. <hr><h2>Member Function Documentation</h2> <h3 class=fn><a name="TQComboTableItem"></a>TQComboTableItem::TQComboTableItem ( <a href="ntqtable.html">TQTable</a> * table, const <a href="ntqstringlist.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="qtableitem.html#isReplaceable">isReplaceable</a>() returns FALSE by default. <p> <p>See also <a href="ntqtable.html#clearCell">TQTable::clearCell</a>() and <a href="qtableitem.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="ntqstring.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="qtableitem.html#rtti">TQTableItem::rtti</a>(). <p>Reimplemented from <a href="qtableitem.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="ntqstring.html">TQString</a> & s )<tt> [virtual]</tt> </h3> This is an overloaded member function, provided for convenience.
