|
||
|
|
|
||
|
|
<p> The QFileIconProvider class provides icons for <a href="qfiledialog.html">QFileDialog</a> to
|
||
|
|
use.
|
||
|
|
<p>
|
||
|
|
<p> By default QFileIconProvider is not used, but any application or
|
||
|
|
library can subclass it, reimplement <a href="#pixmap">pixmap</a>() to return a suitable
|
||
|
|
icon, and make all QFileDialog objects use it by calling the static
|
||
|
|
function <a href="qfiledialog.html#setIconProvider">QFileDialog::setIconProvider</a>().
|
||
|
|
<p> It is advisable to make all the icons that QFileIconProvider returns be
|
||
|
|
the same size or at least the same width. This makes the list view
|
||
|
|
look much better.
|
||
|
|
<p> <p>See also <a href="qfiledialog.html">QFileDialog</a> and <a href="misc.html">Miscellaneous Classes</a>.

||
|
|
<h3 class=fn><a name="QFileIconProvider"></a>QFileIconProvider::QFileIconProvider ( <a href="qobject.html">QObject</a> * parent = 0, const char * name = 0 )
|
||
|
|
</h3> Constructs an empty file icon provider called <em>name</em>, with the
|
||
|
|
parent <em>parent</em>.
|
||
|
|
|
||
|
|
<h3 class=fn>const <a href="qpixmap.html">QPixmap</a> * <a name="pixmap"></a>QFileIconProvider::pixmap ( const <a href="qfileinfo.html">QFileInfo</a> & info )<tt> [virtual]</tt>
|
||
|
|
</h3>
|
||
|
|
Returns a pointer to a pixmap that should be used to
|
||
|
|
signify the file with the information <em>info</em>.
|
||
|
|
<p> If <a href="#pixmap">pixmap</a>() returns 0, <a href="qfiledialog.html">QFileDialog</a> draws the default pixmap.
|
||
|
|
<p> The default implementation returns particular icons for files, directories,
|
||
|
|
link-files and link-directories. It returns a blank "icon" for other types.
|
||
|
|
<p> If you return a pixmap here, it should measure 16x16 pixels.
