The cells have a fixed size and are identified -with a row index and a column index. The top-left cell is in row -0, column 0. The bottom-right cell is in row <a href="#numRows">numRows</a>()-1, column -<a href="#numCols">numCols</a>()-1. -<p> You can define <a href="#numRows-prop">numRows</a>, <a href="#numCols-prop">numCols</a>, <a href="#cellWidth-prop">cellWidth</a> and <a href="#cellHeight-prop">cellHeight</a>. Reimplement the pure virtual function <a href="#paintCell">paintCell</a>() to -draw the contents of a cell. -<p> With <a href="#ensureCellVisible">ensureCellVisible</a>(), you can ensure a certain cell is -visible. With <a href="#rowAt">rowAt</a>() and <a href="#columnAt">columnAt</a>() you can find a cell based on -the given x- and y-coordinates. -<p> If you need to monitor changes to the grid's dimensions (i.e. when -numRows or numCols is changed), reimplement the <a href="#dimensionChange">dimensionChange</a>() -change handler. -<p> Note: the row and column indices are always given in the order, -row (vertical offset) then column (horizontal offset). This order -is the opposite of all pixel operations, which are given in the -order x (horizontal offset), y (vertical offset). -<p> TQGridView is a very simple abstract class based on <a href="qscrollview.html">TQScrollView</a>. It -is designed to simplify the task of drawing many cells of the same -size in a potentially scrollable canvas. If you need rows and -columns with different sizes, use a <a href="qtable.html">TQTable</a> instead. If you need a -simple list of items, use a <a href="qlistbox.html">TQListBox</a>. If you need to present -hierachical data use a <a href="qlistview.html">TQListView</a>, and if you need random objects -at random positions, consider using either a <a href="qiconview.html">TQIconView</a> or a -<a href="qcanvas.html">TQCanvas</a>. -<p>See also <a href="abstractwidgets.html">Abstract Widget Classes</a>. - -<hr><h2>Member Function Documentation</h2> -<h3 class=fn><a name="TQGridView"></a>TQGridView::TQGridView ( <a href="qwidget.html">TQWidget</a> * parent = 0, const char * name = 0, WFlags f = 0 ) -</h3> -Constructs a grid view. -<p> The <em>parent</em>, <em>name</em> and <a href="qt.html#WidgetFlags">widget flag</a>, <em>f</em>, arguments are passed -to the <a href="qscrollview.html">TQScrollView</a> constructor. - -<h3 class=fn><a name="~TQGridView"></a>TQGridView::~TQGridView () -</h3> -Destroys the grid view. - -<h3 class=fn><a href="qrect.html">TQRect</a> <a name="cellGeometry"></a>TQGridView::cellGeometry ( int row, int column ) -</h3> -Returns the geometry of cell (<em>row</em>, <em>column</em>) in the content -coordinate system. -<p> <p>See also <a href="#cellRect">cellRect</a>(). - -<h3 class=fn>int <a name="cellHeight"></a>TQGridView::cellHeight () const -</h3><p>Returns the height of a grid row. -See the <a href="qgridview.html#cellHeight-prop">"cellHeight"</a> property for details. -<h3 class=fn><a href="qrect.html">TQRect</a> <a name="cellRect"></a>TQGridView::cellRect () const -</h3> - -<p> Returns the geometry of a cell in a cell's coordinate system.
