<!-- $$$Q3GridView-description -->
<div class="descr">
<h2>Detailed Description</h2>
<p>The Q3GridView class provides an abstract base for fixed-size grids.</p>
<p>A grid view consists of a number of abstract cells organized in rows and columns. 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="q3gridview.html#numRows-prop">numRows</a>()-1, column <a href="q3gridview.html#numCols-prop">numCols</a>()-1.</p>
<p>You can define <a href="q3gridview.html#numRows-prop">numRows</a>, <a href="q3gridview.html#numCols-prop">numCols</a>, <a href="q3gridview.html#cellWidth-prop">cellWidth</a> and <a href="q3gridview.html#cellHeight-prop">cellHeight</a>. Reimplement the pure virtual function <a href="q3gridview.html#paintCell">paintCell</a>() to draw the contents of a cell.</p>
<p>With <a href="q3gridview.html#ensureCellVisible">ensureCellVisible</a>(), you can ensure a certain cell is visible. With <a href="q3gridview.html#rowAt">rowAt</a>() and <a href="q3gridview.html#columnAt">columnAt</a>() you can find a cell based on the given x- and y-coordinates.</p>
<p>If you need to monitor changes to the grid's dimensions (i.e. when <a href="q3gridview.html#numRows-prop">numRows</a> or <a href="q3gridview.html#numCols-prop">numCols</a> is changed), reimplement the <a href="q3gridview.html#dimensionChange">dimensionChange</a>() change handler.</p>
<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>
<p>Q3GridView is a very simple abstract class based on <a href="q3scrollview.html">Q3ScrollView</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="q3table.html">Q3Table</a> instead. If you need a simple list of items, use a <a href="q3listbox.html">Q3ListBox</a>. If you need to present hierarichal data use a <a href="q3listview.html">Q3ListView</a>, and if you need random objects at random positions, consider using either a <a href="q3iconview.html">Q3IconView</a> or a <a href="q3canvas.html">Q3Canvas</a>.</p>

<h3 class="fn"><a name="gridSize"></a><span class="type"><a href="qsize.html">QSize</a></span> Q3GridView::<span class="name">gridSize</span> () const</h3>

<p>This pure virtual function is called to paint the single cell at (<i>row</i>, <i>col</i>) using painter <i>p</i>. The painter must be open when paintCell() is called and must remain open.</p>
<p>The coordinate system is <a href="qpainter.html#translate">translated</a> so that the origin is at the top-left corner of the cell to be painted, i.e. <i>cell</i> coordinates. Do not scale or shear the coordinate system (or if you do, restore the transformation matrix before you return).</p>
<p>The painter is not clipped by default in order to get maximum efficiency. If you want clipping, use</p>
<pre class="cpp"> p<span class="operator">-</span><span class="operator">></span>setClipRect(cellRect()<span class="operator">,</span> <span class="type"><a href="qpainter.html">QPainter</a></span><span class="operator">::</span>CoordPainter);

<p>This function fills the <i>cw</i> pixels wide and <i>ch</i> pixels high rectangle starting at position (<i>cx</i>, <i>cy</i>) with the background color using the painter <i>p</i>.</p>

<p>Repaints cell (<i>row</i>, <i>column</i>).</p>
<p>If <i>erase</i> is true, Qt erases the area of the cell before the <a href="q3gridview.html#paintCell">paintCell</a>() call; otherwise no erasing takes place.</p>
