Any number of widgetsmay be controlled.<p> To show a <a href="qlistbox.html">QListBox</a>, a <a href="qlistview.html">QListView</a> and a <a href="qtextedit.html">QTextEdit</a> side by side:<p> <pre> QSplitter *split = new QSplitter( parent ); <a href="qlistbox.html">QListBox</a> *lb = new <a href="qlistbox.html">QListBox</a>( split ); <a href="qlistview.html">QListView</a> *lv = new <a href="qlistview.html">QListView</a>( split ); <a href="qtextedit.html">QTextEdit</a> *ed = new <a href="qtextedit.html">QTextEdit</a>( split ); </pre> <p> In QSplitter the boundary can be either horizontal or vertical. Thedefault is horizontal (the children are side by side) but youcan use <a href="#setOrientation">setOrientation</a>( QSplitter::Vertical ) to set it to vertical.<p> By default, all widgets can be as large or as small as the userwishes, down to <a href="qwidget.html#minimumSizeHint">minimumSizeHint()</a>. You can also use <a href="qwidget.html#setMinimumSize">setMinimumSize</a>() and<a href="qwidget.html#setMaximumSize">setMaximumSize</a>() on the children. Use <a href="#setResizeMode">setResizeMode</a>() to specifythat a widget should keep its size when the splitter is resized.<p> Although QSplitter normally resizes the children only at the end of aresize operation, if you call <a href="#setOpaqueResize">setOpaqueResize</a>( TRUE ) thewidgets are resized as often as possible.<p> The initial distribution of size between the widgets is determinedby the initial size of each widget. You can also use <a href="#setSizes">setSizes</a>() toset the sizes of all the widgets. The function <a href="#sizes">sizes</a>() returns thesizes set by the user.<p> If you <a href="qwidget.html#hide">hide</a>() a child its space will be distributed among the otherchildren. It will be reinstated when you <a href="qwidget.html#show">show</a>() it again. It is alsopossible to reorder the widgets within the splitter using<a href="#moveToFirst">moveToFirst</a>() and <a href="#moveToLast">moveToLast</a>().<p> <img src=qsplitter-m.png> <img src=qsplitter-w.png><p> <p>See also <a href="qtabbar.html">QTabBar</a> and <a href="organizers.html">Organizers</a>.<hr><h2>Member Type Documentation</h2><h3 class=fn><a name="ResizeMode-enum"></a>QSplitter::ResizeMode</h3> <p> This enum type describes how QSplitter will resize each of its child widgets.
