button and popup list. +<p> + +<p> A combobox is a selection widget which displays the current item +and can pop up a list of items. A combobox may be editable in +which case the user can enter arbitrary strings. +<p> Comboboxes provide a means of showing the user's current choice +out of a list of options in a way that takes up the minimum amount +of screen space. +<p> TQComboBox supports three different display styles: Aqua/Motif 1.x, +<a href="motif-extension.html#Motif">Motif</a> 2.0 and Windows. In Motif 1.x, a combobox was called +XmOptionMenu. In Motif 2.0, OSF introduced an improved combobox +and named that XmComboBox. TQComboBox provides both. +<p> TQComboBox provides two different constructors. The simplest +constructor creates an "old-style" combobox in Motif (or Aqua) +style: +<pre> + TQComboBox *c = new TQComboBox( this, "read-only combobox" ); + </pre> + +<p> The other constructor creates a new-style combobox in Motif style, +and can create both read-only and editable comboboxes: +<pre> + TQComboBox *c1 = new TQComboBox( FALSE, this, "read-only combobox" ); + TQComboBox *c2 = new TQComboBox( TRUE, this, "editable combobox" ); + </pre> + +<p> New-style comboboxes use a list box in both Motif and Windows +styles, and both the content size and the on-screen size of the +list box can be limited with <a href="#sizeLimit">sizeLimit</a>() and <a href="#setMaxCount">setMaxCount</a>() +respectively. Old-style comboboxes use a popup in Aqua and Motif +style, and that popup will happily grow larger than the desktop if +you put enough data into it. +<p> The two constructors create identical-looking comboboxes in +Windows style. +<p> Comboboxes can contain pixmaps as well as strings; the +<a href="#insertItem">insertItem</a>() and <a href="#changeItem">changeItem</a>() functions are suitably overloaded. +For editable comboboxes, the function <a href="#clearEdit">clearEdit</a>() is provided, +to clear the displayed string without changing the combobox's +contents. +<p> A combobox emits two signals, <a href="#activated">activated</a>() and <a href="#highlighted">highlighted</a>(), when +a new item has been activated (selected) or highlighted (made +current). Both signals exist in two versions, one with a <a href="ntqstring.html">TQString</a> argument and one with an <tt>int</tt> argument. If the user +highlights or activates a pixmap, only the <tt>int</tt> signals are +emitted. Whenever the text of an editable combobox is changed the +<a href="#textChanged">textChanged</a>() signal is emitted. +<p> When the user enters a new string in an editable combobox, the +widget may or may not insert it, and it can insert it in several +locations. The default policy is is <a href="#Policy-enum">AtBottom</a> but you can change +this using <a href="#setInsertionPolicy">setInsertionPolicy</a>(). +<p> It is possible to constrain the input to an editable combobox +using <a href="ntqvalidator.html">TQValidator</a>; see <a href="#setValidator">setValidator</a>(). By default, any input is +accepted. +<p> If the combobox is not editable then it has a default +<a href="ntqwidget.html#focusPolicy">focusPolicy</a>() of <a href="ntqwidget.html#FocusPolicy-enum">TabFocus</a>, i.e. it will not grab focus if +clicked. This differs from both Windows and Motif. If the combobox +is editable then it has a default focusPolicy() of <a href="ntqwidget.html#FocusPolicy-enum">StrongFocus</a>, +i.e. it will grab focus if clicked. +<p> A combobox can be populated using the insert functions, +<a href="#insertStringList">insertStringList</a>() and <a href="#insertItem">insertItem</a>() for example. Items can be +changed with <a href="#changeItem">changeItem</a>(). An item can be removed with +<a href="#removeItem">removeItem</a>() and all items can be removed with <a href="#clear">clear</a>(). The text +of the current item is returned by <a href="#currentText">currentText</a>(), and the text of +a numbered item is returned with <a href="#text">text</a>(). The current item can be +set with <a href="#setCurrentItem">setCurrentItem</a>() or <a href="#setCurrentText">setCurrentText</a>(). The number of items +in the combobox is returned by <a href="#count">count</a>(); the maximum number of +items can be set with <a href="#setMaxCount">setMaxCount</a>(). You can allow editing using +<a href="#setEditable">setEditable</a>(). For editable comboboxes you can set auto-completion +using <a href="#setAutoCompletion">setAutoCompletion</a>() and whether or not the user can add +duplicates is set with <a href="#setDuplicatesEnabled">setDuplicatesEnabled</a>(). +<p> <img src="qcombo1-m.png">(Motif 1, read-only)<br clear=all> +<img src="qcombo2-m.png">(Motif 2, editable)<br clear=all> +<img src="qcombo3-m.png">(Motif 2, read-only)<br clear=all> +<img src="qcombo1-w.png">(Windows style) +<p> Depending on the style, TQComboBox will use a <a href="ntqlistbox.html">TQListBox</a> or a +<a href="ntqpopupmenu.html">TQPopupMenu</a> to display the list of items. See <a href="#setListBox">setListBox</a>() for +more information. +<p> <p>See also <a href="ntqlineedit.html">TQLineEdit</a>, <a href="ntqlistbox.html">TQListBox</a>, <a href="ntqspinbox.html">TQSpinBox</a>, <a href="ntqradiobutton.html">TQRadioButton</a>, <a href="ntqbuttongroup.html">TQButtonGroup</a>, <a href="guibooks.html#fowler">GUI Design Handbook: Combo Box</a>, <a href="guibooks.html#fowler">GUI Design Handbook: Drop-Down List Box</a>, and <a href="basic.html">Basic Widgets</a>. + +<hr><h2>Member Type Documentation</h2> +<h3 class=fn><a name="Policy-enum"></a>TQComboBox::Policy</h3> + +<p> This enum specifies what the TQComboBox should do when a new string +is entered by the user. +<ul> +<li><tt>TQComboBox::NoInsertion</tt> - the string will not be inserted into the +combobox. +<li><tt>TQComboBox::AtTop</tt> - insert the string as the first item in the combobox. +<li><tt>TQComboBox::AtCurrent</tt> - replace the previously selected item with the +string the user has entered. +<li><tt>TQComboBox::AtBottom</tt> - insert the string as the last item in the +combobox. +<li><tt>TQComboBox::AfterCurrent</tt> - insert the string after the previously +selected item. +<li><tt>TQComboBox::BeforeCurrent</tt> - insert the string before the previously +selected item. +</ul><p> <a href="#activated">activated</a>() is always emitted when the string is entered. +<p> If inserting the new string would cause the combobox to breach its +content size limit, the item at the other end of the list is +deleted.
