+
+
+<p> The QGridLayout class lays out widgets in a grid.
+<p>
+
+
+<p> QGridLayout takes the space made available to it (by its parent
+layout or by the <a href="qlayout.html#mainWidget">mainWidget</a>()), divides it up into rows and
+columns, and puts each widget it manages into the correct cell.
+<p> Columns and rows behave identically; we will discuss columns, but
+there are equivalent functions for rows.
+<p> Each column has a minimum width and a <a href="layout.html#stretch-factor">stretch factor</a>. The minimum
+width is the greatest of that set using <a href="#addColSpacing">addColSpacing</a>() and the
+minimum width of each widget in that column. The stretch factor is
+set using <a href="#setColStretch">setColStretch</a>() and determines how much of the available
+space the column will get over and above its necessary minimum.
+<p> Normally, each managed widget or layout is put into a cell of its
+own using <a href="#addWidget">addWidget</a>(), <a href="#addLayout">addLayout</a>() or by the <a href="qlayout.html#setAutoAdd">auto-add facility</a>. It is also
+possible for a widget to occupy multiple cells using
+<a href="#addMultiCellWidget">addMultiCellWidget</a>(). If you do this, QGridLayout will guess how
+to distribute the size over the columns/rows (based on the stretch
+factors).
+<p> To remove a widget from a layout, call <a href="qlayout.html#remove">remove</a>(). Calling
+<a href="qwidget.html#hide">QWidget::hide</a>() on a widget also effectively removes the widget
+from the layout until <a href="qwidget.html#show">QWidget::show</a>() is called.
+<p> This illustration shows a fragment of a dialog with a five-column,
+three-row grid (the grid is shown overlaid in magenta):
+<p> <center><img src="gridlayout.png"></center>
+<p> Columns 0, 2 and 4 in this dialog fragment are made up of a
+<a href="qlabel.html">QLabel</a>, a <a href="qlineedit.html">QLineEdit</a>, and a <a href="qlistbox.html">QListBox</a>. Columns 1 and 3 are
+placeholders made with <a href="#addColSpacing">addColSpacing</a>(). Row 0 consists of three
+QLabel objects, row 1 of three QLineEdit objects and row 2 of
+three QListBox objects. We used placeholder columns (1 and 3) to
+get the right amount of space between the columns.
+<p> Note that the columns and rows are not equally wide or tall. If
+you want two columns to have the same width, you must set their
+minimum widths and stretch factors to be the same yourself. You do
+this using addColSpacing() and <a href="#setColStretch">setColStretch</a>().
+<p> If the QGridLayout is not the top-level layout (i.e. does not
+manage all of the widget's area and children), you must add it to
+its parent layout when you create it, but before you do anything
+with it. The normal way to add a layout is by calling
+parentLayout-&gt;addLayout().
+<p> Once you have added your layout you can start putting widgets and
+other layouts into the cells of your grid layout using
+<a href="#addWidget">addWidget</a>(), <a href="#addLayout">addLayout</a>() and <a href="#addMultiCellWidget">addMultiCellWidget</a>().
+<p> QGridLayout also includes two margin widths: the border and the
+spacing. The border is the width of the reserved space along each
+of the QGridLayout's four sides. The spacing is the width of the
+automatically allocated spacing between neighboring boxes.
+<p> Both the border and the spacing are parameters of the constructor
+and default to 0.

+</h3>
+Constructs a new QGridLayout with <em>nRows</em> rows, <em>nCols</em> columns

+layout is called <em>name</em>.
+<p> <em>margin</em> is the number of pixels between the edge of the widget

+Constructs a new grid with <em>nRows</em> rows and <em>nCols</em> columns. If

+will not be performed before this is inserted into another layout.

+<h3 class=fn>void <a name="addLayout"></a>QGridLayout::addLayout ( <a href="qlayout.html">QLayout</a>&nbsp;*&nbsp;layout, int&nbsp;row, int&nbsp;col )
+</h3>
+Places the <em>layout</em> at position (<em>row</em>, <em>col</em>) in the grid. The
+top-left position is (0, 0).
+<p> <em>layout</em> becomes a child of the grid layout.
+<p> When a layout is constructed with another layout as its parent,

+</h3>
+<b>This function is obsolete.</b> It is provided to keep old source working. We strongly advise against using it in new code.

+</h3>
+Adds the widget <em>w</em> to the cell grid at <em>row</em>, <em>col</em>. The
+top-left position is (0, 0) by default.
+<p> Alignment is specified by <em>alignment</em>, which is a bitwise OR of

+<p> <li> From Qt 3.0, the <em>alignment</em> parameter is interpreted more
