Each widget (or other box) +will get at least its minimum size and at most its maximum size. +Any excess space is shared according to the stretch factors (more +about that below). +<p> <center><img src="qvbox-m.png" alt="Vertical box with five child widgets"></center> +<p> If the TQBoxLayout's orientation is <a href="qt.html#Orientation-enum">Vertical</a>, the boxes are +placed in a column, again with suitable sizes. +<p> The easiest way to create a TQBoxLayout is to use one of the +convenience classes, e.g. <a href="qhboxlayout.html">TQHBoxLayout</a> (for <a href="qt.html#Orientation-enum">Horizontal</a> boxes) or +<a href="qvboxlayout.html">TQVBoxLayout</a> (for <a href="qt.html#Orientation-enum">Vertical</a> boxes). You can also use the +TQBoxLayout constructor directly, specifying its direction as <a href="#Direction-enum">LeftToRight</a>, <a href="#Direction-enum">Down</a>, <a href="#Direction-enum">RightToLeft</a> or <a href="#Direction-enum">Up</a>. +<p> If the TQBoxLayout is not the top-level layout (i.e. it is not +managing all of the widget's area and children), you must add it +to its parent layout before you can do anything with it. The +normal way to add a layout is by calling +parentLayout->addLayout(). +<p> Once you have done this, you can add boxes to the TQBoxLayout using +one of four functions: +<p> <ul> +<li> <a href="#addWidget">addWidget</a>() to add a widget to the TQBoxLayout and set the +widget's <a href="layout.html#stretch-factor">stretch factor</a>. (The stretch factor is along the row of +boxes.) +<p> <li> <a href="#addSpacing">addSpacing</a>() to create an empty box; this is one of the +functions you use to create nice and spacious dialogs. See below +for ways to set margins. +<p> <li> <a href="#addStretch">addStretch</a>() to create an empty, stretchable box. +<p> <li> <a href="#addLayout">addLayout</a>() to add a box containing another <a href="qlayout.html">TQLayout</a> to the row +and set that layout's stretch factor. +</ul> +<p> Use <a href="#insertWidget">insertWidget</a>(), <a href="#insertSpacing">insertSpacing</a>(), <a href="#insertStretch">insertStretch</a>() or +<a href="#insertLayout">insertLayout</a>() to insert a box at a specified position in the +layout. +<p> TQBoxLayout also includes two margin widths: +<p> <ul> +<li> <a href="qlayout.html#setMargin">setMargin</a>() sets the width of the outer border. This is the width +of the reserved space along each of the TQBoxLayout's four sides. +<li> <a href="qlayout.html#setSpacing">setSpacing</a>() sets the width between neighboring boxes. (You +can use <a href="#addSpacing">addSpacing</a>() to get more space at a particular spot.) +</ul> +<p> The margin defaults to 0. The spacing defaults to the same as the +margin width for a top-level layout, or to the same as the parent +layout. Both are parameters to the constructor. +<p> To remove a widget from a layout, call <a href="qlayout.html#remove">remove</a>(). Calling +<a href="qwidget.html#hide">TQWidget::hide</a>() on a widget also effectively removes the widget +from the layout until <a href="qwidget.html#show">TQWidget::show</a>() is called. +<p> You will almost always want to use <a href="qvboxlayout.html">TQVBoxLayout</a> and <a href="qhboxlayout.html">TQHBoxLayout</a> +rather than TQBoxLayout because of their convenient constructors. +<p> <p>See also <a href="qgrid.html">TQGrid</a>, <a href="layout.html">Layout Overview</a>, <a href="appearance.html">Widget Appearance and Style</a>, and <a href="geomanagement.html">Layout Management</a>. + +<hr><h2>Member Type Documentation</h2> +<h3 class=fn><a name="Direction-enum"></a>TQBoxLayout::Direction</h3> + +<p> This type is used to determine the direction of a box layout. +<ul> +<li><tt>TQBoxLayout::LeftToRight</tt> - Horizontal, from left to right +<li><tt>TQBoxLayout::RightToLeft</tt> - Horizontal, from right to left +<li><tt>TQBoxLayout::TopToBottom</tt> - Vertical, from top to bottom +<li><tt>TQBoxLayout::Down</tt> - The same as <a href="#Direction-enum">TopToBottom</a> +<li><tt>TQBoxLayout::BottomToTop</tt> - Vertical, from bottom to top +<li><tt>TQBoxLayout::Up</tt> - The same as <a href="#Direction-enum">BottomToTop</a> +</ul> +<hr><h2>Member Function Documentation</h2> +<h3 class=fn><a name="TQBoxLayout"></a>TQBoxLayout::TQBoxLayout ( <a href="qwidget.html">TQWidget</a> * parent, <a href="qboxlayout.html#Direction-enum">Direction</a> d, int margin = 0, int spacing = -1, const char * name = 0 ) +</h3> +Constructs a new TQBoxLayout with direction <em>d</em> and main widget <em>parent</em>. <em>parent</em> may not be 0. +<p> The <em>margin</em> is the number of pixels between the edge of the +widget and its managed children.
