In situations where you need to create very large tables you may prefer an alternative approach to using QTableItems: see the <a href="qtable.html#notes-on-large-tables">notes on large tables</a>. <p> A QTableItem contains a cell's data, by default, a string and a pixmap. The table item also holds the cell's display size and how the data should be aligned. The table item specifies the cell's <a href="#EditType-enum">EditType</a> and the editor used for in-place editing (by default a <a href="qlineedit.html">QLineEdit</a>). If you want checkboxes use <a href="qchecktableitem.html">QCheckTableItem</a>, and if you want comboboxes use <a href="qcombotableitem.html">QComboTableItem</a>. The <a href="#EditType-enum">EditType</a> (set in the constructor) determines whether the cell's contents may be edited. <p> If a pixmap is specified it is displayed to the left of any text. You can change the text or pixmap with <a href="#setText">setText</a>() and <a href="#setPixmap">setPixmap</a>() respectively. For text you can use <a href="#setWordWrap">setWordWrap</a>(). <p> When sorting table items the <a href="#key">key</a>() function is used; by default this returns the table item's <a href="#text">text</a>(). Reimplement key() to customize how your table items will sort. <p> Table items are inserted into a table using <a href="qtable.html#setItem">QTable::setItem</a>(). If you insert an item into a cell that already contains a table item the original item will be deleted. <p> Example: <pre> for ( int row = 0; row < table->numRows(); row++ ) { for ( int col = 0; col < table->numCols(); col++ ) { table->setItem( row, col, new QTableItem( table, QTableItem::<a href="#EditType-enum">WhenCurrent</a>, QString::number( row * col ) ) ); } } </pre> <p> You can move a table item from one cell to another, in the same or a different table, using <a href="qtable.html#takeItem">QTable::takeItem</a>() and QTable::setItem() but see also <a href="qtable.html#swapCells">QTable::swapCells</a>(). <p> Table items can be deleted with delete in the standard way; the table and cell will be updated accordingly. <p> Note, that if you have a table item that is not currently in a table then anything you do to that item other than insert it into a table will result in undefined behaviour. <p> Reimplement <a href="#createEditor">createEditor</a>() and <a href="#setContentFromEditor">setContentFromEditor</a>() if you want to use your own widget instead of a <a href="qlineedit.html">QLineEdit</a> for editing cell contents. Reimplement <a href="#paint">paint</a>() if you want to display custom content. <p> It is important to ensure that your custom widget can accept the <a href="focus.html#keyboard-focus">keyboard focus</a>, so that the user can use the tab key to navigate the table as normal. Therefore, if the widget returned by createEditor() does not itself accept the keyboard focus, it is necessary to nominate a child widget to do so on its behalf. For example, a <a href="qhbox.html">QHBox</a> with two child QLineEdit widgets may use one of them to accept the keyboard focus: <p> <pre> QWidget* MyTableItem::createEditor() const { <a href="qhbox.html">QHBox</a>* hbox = new <a href="qhbox.html">QHBox</a>( <a href="#table">table</a>()->viewport() ); hbox-><a href="qwidget.html#setFocusProxy">setFocusProxy</a>(new <a href="qlineedit.html">QLineEdit</a>( hbox )); new <a href="qlineedit.html">QLineEdit</a>( hbox ); return hbox; } </pre> <p> By default, table items may be replaced by new QTableItems during the lifetime of a <a href="qtable.html">QTable</a>. Therefore, if you create your own subclass of QTableItem, and you want to ensure that this does not happen, you must call <a href="#setReplaceable">setReplaceable</a>(FALSE) in the constructor of your subclass. <p> <center><img src="qtableitems.png" alt="Table Items"></center> <p> <p>See also <a href="qchecktableitem.html">QCheckTableItem</a>, <a href="qcombotableitem.html">QComboTableItem</a>, and <a href="advanced.html">Advanced Widgets</a>. <p> <hr><h2>Member Type Documentation</h2> <h3 class=fn><a name="EditType-enum"></a>QTableItem::EditType</h3> <p> <a name="wheneditable"></a> This enum is used to define whether a cell is editable or read-only (in conjunction with other settings), and how the cell should be displayed. <ul> <li><tt>QTableItem::Always</tt> - The cell always <em>looks</em> editable. </ul><p> Using this EditType ensures that the editor created with <a href="#createEditor">createEditor</a>() (by default a <a href="qlineedit.html">QLineEdit</a>) is always visible. This has implications for the alignment of the content: the default editor aligns everything (even numbers) to the left whilst numerical values in the cell are by default aligned to the right. <p> If a cell with the edit type <a href="#EditType-enum">Always</a> looks misaligned you could reimplement createEditor() for these items. <ul> <li><tt>QTableItem::WhenCurrent</tt> - The cell <em>looks</em> editable only when it has <a href="focus.html#keyboard-focus">keyboard focus</a> (see <a href="qtable.html#setCurrentCell">QTable::setCurrentCell</a>()). <li><tt>QTableItem::OnTyping</tt> - The cell <em>looks</em> editable only when the user types in it or double-clicks it. It resembles the <a href="#EditType-enum">WhenCurrent</a> functionality but is, perhaps, nicer. </ul><p> The <a href="#EditType-enum">OnTyping</a> edit type is the default when QTableItem objects are created by the convenience functions <a href="qtable.html#setText">QTable::setText</a>() and <a href="qtable.html#setPixmap">QTable::setPixmap</a>(). <ul> <li><tt>QTableItem::Never</tt> - The cell is not editable. </ul><p> The cell is actually editable only if <a href="qtable.html#isRowReadOnly">QTable::isRowReadOnly</a>() is FALSE for its row, <a href="qtable.html#isColumnReadOnly">QTable::isColumnReadOnly</a>() is FALSE for its column, and <a href="qtable.html#isReadOnly">QTable::isReadOnly</a>() is FALSE. <p> QComboTableItems have an isEditable() property. This property is used to indicate whether the user may enter their own text or are restricted to choosing one of the choices in the list.

Use <a href="qtable.html#updateCell">QTable::updateCell</a>() to repaint the cell's contents. <p> <p>See also <a href="qtable.html#setText">QTable::setText</a>(), <a href="#text">text</a>(), <a href="#setPixmap">setPixmap</a>(), and <a href="qtable.html#updateCell">QTable::updateCell</a>(). <p>Example: <a href="statistics-example.html#x2788">table/statistics/statistics.cpp</a>. <h3 class=fn>void <a name="setWordWrap"></a>QTableItem::setWordWrap ( bool b )<tt> [virtual]</tt> </h3> If <em>b</em> is TRUE, the cell's text will be wrapped over multiple lines, when necessary, to fit the width of the cell; otherwise the text will be written as a single line. <p> <p>See also <a href="#wordWrap">wordWrap</a>(), <a href="qtable.html#adjustColumn">QTable::adjustColumn</a>(), and <a href="qtable.html#setColumnStretchable">QTable::setColumnStretchable</a>(). <h3 class=fn><a href="qsize.html">QSize</a> <a name="sizeHint"></a>QTableItem::sizeHint () const<tt> [virtual]</tt> </h3> This virtual function returns the size a cell needs to show its entire content. <p> If you subclass QTableItem you will often need to reimplement this function. <h3 class=fn><a href="qtable.html">QTable</a> * <a name="table"></a>QTableItem::table () const </h3> <p> Returns the <a href="qtable.html">QTable</a> the table item belongs to. <p> <p>See also <a href="qtable.html#setItem">QTable::setItem</a>() and <a href="#QTableItem">QTableItem</a>(). <h3 class=fn><a href="qstring.html">QString</a> <a name="text"></a>QTableItem::text () const<tt> [virtual]</tt> </h3> Returns the text of the table item or <a href="qstring.html#QString-null">QString::null</a> if there is no text. <p> To ensure that the current value of the editor is returned, <a href="#setContentFromEditor">setContentFromEditor</a>() is called: <ol type=1> <li> if the editMode() is <a href="#EditType-enum">Always</a>, or <li> if editMode() is <em>not</em> <a href="#EditType-enum">Always</a> but the editor of the cell is active and the editor is not a <a href="qlineedit.html">QLineEdit</a>. </ol> <p> This means that <a href="#text">text</a>() returns the original text value of the item if the editor is a line edit, until the user commits an edit (e.g. by pressing Enter or Tab) in which case the new text is returned. For other editors (e.g. a combobox) setContentFromEditor() is always called so the currently display value is the one returned. <p> <p>See also <a href="#setText">setText</a>() and <a href="#pixmap">pixmap</a>(). <h3 class=fn>bool <a name="wordWrap"></a>QTableItem::wordWrap () const </h3> Returns TRUE if word wrap is enabled for the cell; otherwise returns FALSE. <p> <p>See also <a href="#setWordWrap">setWordWrap</a>(). <!-- eof --> <hr><p> This file is part of the <a href="index.html">Qt toolkit</a>.
