single-column list in which either no item or -one item is selected, but it can also be used in many other ways. -<p> TQListBox will add scroll bars as necessary, but it isn't intended -for <em>really</em> big lists. If you want more than a few thousand -items, it's probably better to use a different widget mainly -because the scroll bars won't provide very good navigation, but -also because TQListBox may become slow with huge lists. (See -<a href="qlistview.html">TQListView</a> and <a href="qtable.html">TQTable</a> for possible alternatives.) -<p> There are a variety of selection modes described in the -TQListBox::SelectionMode documentation. The default is <a href="#SelectionMode-enum">Single</a> -selection mode, but you can change it using <a href="#setSelectionMode">setSelectionMode</a>(). -(<a href="#setMultiSelection">setMultiSelection</a>() is still provided for compatibility with TQt -1.x. We recommend using setSelectionMode() in all code.) -<p> Because TQListBox offers multiple selection it must display -<a href="focus.html#keyboard-focus">keyboard focus</a> and selection state separately. Therefore there are -functions both to set the selection state of an item, i.e. -<a href="#setSelected">setSelected</a>(), and to set which item displays keyboard focus, i.e. -<a href="#setCurrentItem">setCurrentItem</a>(). -<p> The list box normally arranges its items in a single column and -adds a vertical scroll bar if required. It is possible to have a -different fixed number of columns (<a href="#setColumnMode">setColumnMode</a>()), or as many -columns as will fit in the list box's assigned screen space -(setColumnMode(FitToWidth)), or to have a fixed number of rows -(<a href="#setRowMode">setRowMode</a>()) or as many rows as will fit in the list box's -assigned screen space (setRowMode(FitToHeight)). In all these -cases TQListBox will add scroll bars, as appropriate, in at least -one direction. -<p> If multiple rows are used, each row can be as high as necessary -(the normal setting), or you can request that all items will have -the same height by calling <a href="#setVariableHeight">setVariableHeight</a>(FALSE). The same -applies to a column's width, see <a href="#setVariableWidth">setVariableWidth</a>(). -<p> The TQListBox's items are <a href="qlistboxitem.html">TQListBoxItem</a> objects. TQListBox provides -methods to insert new items as strings, as pixmaps, and as -TQListBoxItem * (<a href="#insertItem">insertItem</a>() with various arguments), and to -replace an existing item with a new string, pixmap or TQListBoxItem -(<a href="#changeItem">changeItem</a>() with various arguments). You can also remove items -singly with <a href="#removeItem">removeItem</a>() or <a href="#clear">clear</a>() the entire list box. Note that -if you create a TQListBoxItem yourself and insert it, TQListBox -takes ownership of the item. -<p> You can also create a TQListBoxItem, such as <a href="qlistboxtext.html">TQListBoxText</a> or -<a href="qlistboxpixmap.html">TQListBoxPixmap</a>, with the list box as first parameter. The item -will then append itself. When you delete an item it is -automatically removed from the list box. -<p> The list of items can be arbitrarily large; TQListBox will add -scroll bars if necessary. TQListBox can display a single-column -(the common case) or multiple-columns, and offers both single and -multiple selection. TQListBox does not support multiple-column -items (but <a href="qlistview.html">TQListView</a> and <a href="qtable.html">TQTable</a> do), or tree hierarchies (but -TQListView does). -<p> The list box items can be accessed both as <a href="qlistboxitem.html">TQListBoxItem</a> objects -(recommended) and using integer indexes (the original TQListBox -implementation used an array of strings internally, and the API -still supports this mode of operation). Everything can be done -using the new objects, and most things can be done using indexes. -<p> Each item in a TQListBox contains a TQListBoxItem. One of the items -can be the current item. The <a href="#currentChanged">currentChanged</a>() signal and the -<a href="#highlighted">highlighted</a>() signal are emitted when a new item becomes current, -e.g. because the user clicks on it or <a href="#setCurrentItem">TQListBox::setCurrentItem</a>() -is called. The <a href="#selected">selected</a>() signal is emitted when the user -double-clicks on an item or presses Enter on the current item. -<p> If the user does not select anything, no signals are emitted and -<a href="#currentItem">currentItem</a>() returns -1. -<p> A list box has <a href="qwidget.html#FocusPolicy-enum">WheelFocus</a> as a default <a href="qwidget.html#focusPolicy">focusPolicy</a>(), i.e. it -can get keyboard focus by tabbing, clicking and through the use of -the mouse wheel. -<p> New items can be inserted using <a href="#insertItem">insertItem</a>(), <a href="#insertStrList">insertStrList</a>() or -<a href="#insertStringList">insertStringList</a>(). <a href="#inSort">inSort</a>() is obsolete because this method is -quite inefficient. It's preferable to insert the items normally -and call <a href="#sort">sort</a>() afterwards, or to insert a sorted <a href="qstringlist.html">TQStringList</a>(). -<p> By default, vertical and horizontal scroll bars are added and -removed as necessary. <a href="qscrollview.html#setHScrollBarMode">setHScrollBarMode</a>() and <a href="qscrollview.html#setVScrollBarMode">setVScrollBarMode</a>() -can be used to change this policy. -<p> If you need to insert types other than strings and pixmaps, you -must define new classes which inherit <a href="qlistboxitem.html">TQListBoxItem</a>. -<p> <b>Warning:</b> The list box assumes ownership of all list box items and -will delete them when it does not need them any more. -<p> <img src=qlistbox-m.png> <img src=qlistbox-w.png> -<p> <p>See also <a href="qlistview.html">TQListView</a>, <a href="qcombobox.html">TQComboBox</a>, <a href="qbuttongroup.html">TQButtonGroup</a>, <a href="guibooks.html#fowler">GUI Design Handbook: List Box (two - sections)</a>, and <a href="advanced.html">Advanced Widgets</a>. - -<hr><h2>Member Type Documentation</h2> -<h3 class=fn><a name="LayoutMode-enum"></a>TQListBox::LayoutMode</h3> - -<p> This enum type is used to specify how TQListBox lays out its rows -and columns. -<ul> -<li><tt>TQListBox::FixedNumber</tt> - There is a fixed number of rows (or columns). -<li><tt>TQListBox::FitToWidth</tt> - There are as many columns as will fit -on-screen. -<li><tt>TQListBox::FitToHeight</tt> - There are as many rows as will fit on-screen. -<li><tt>TQListBox::Variable</tt> - There are as many rows as are required by the -column mode. (Or as many columns as required by the row mode.) -</ul><p> Example: When you call <a href="#setRowMode">setRowMode</a>( FitToHeight ), <a href="#columnMode">columnMode</a>() -automatically becomes <a href="#LayoutMode-enum">Variable</a> to accommodate the row mode -you've set. - -<h3 class=fn><a name="SelectionMode-enum"></a>TQListBox::SelectionMode</h3> - -<p> This enumerated type is used by TQListBox to indicate how it reacts -to selection by the user. -<ul> -<li><tt>TQListBox::Single</tt> - When the user selects an item, any already-selected -item becomes unselected and the user cannot unselect the selected -item. This means that the user can never clear the selection, even -though the selection may be cleared by the application programmer -using <a href="#clearSelection">TQListBox::clearSelection</a>(). -<li><tt>TQListBox::Multi</tt> - When the user selects an item the selection status -of that item is toggled and the other items are left alone. Also, -multiple items can be selected by dragging the mouse while the -left mouse button is kept pressed. -<li><tt>TQListBox::Extended</tt> - When the user selects an item the selection is -cleared and the new item selected. However, if the user presses -the Ctrl key when clicking on an item, the clicked item gets -toggled and all other items are left untouched. And if the user -presses the Shift key while clicking on an item, all items between -the current item and the clicked item get selected or unselected, -depending on the state of the clicked item. Also, multiple items -can be selected by dragging the mouse while the left mouse button -is kept pressed. -<li><tt>TQListBox::NoSelection</tt> - Items cannot be selected. -</ul><p> In other words, <a href="#SelectionMode-enum">Single</a> is a real single-selection list box, <a href="#SelectionMode-enum">Multi</a> is a real multi-selection list box, <a href="#SelectionMode-enum">Extended</a> is a list -box in which users can select multiple items but usually want to -select either just one or a range of contiguous items, and <a href="#SelectionMode-enum">NoSelection</a> is for a list box where the user can look but not -touch. - -<hr><h2>Member Function Documentation</h2> -<h3 class=fn><a name="TQListBox"></a>TQListBox::TQListBox ( <a href="qwidget.html">TQWidget</a> * parent = 0, const char * name = 0, WFlags f = 0 ) -</h3> -Constructs a new empty list box called <em>name</em> and with parent <em>parent</em>. -<p> Performance is boosted by modifying the widget flags <em>f</em> so that -only part of the <a href="qlistboxitem.html">TQListBoxItem</a> children is redrawn.
