|
|
|
|
|
|
The TQEditorFactory class is used to create editor widgets
|
|
for <a href="tqvariant.html">TQVariant</a> data types.
|
|
<p>
|
|
|
|
<p> Each editor factory provides the <a href="#createEditor">createEditor</a>() function which
|
|
given a TQVariant will create and return a <a href="tqwidget.html">TQWidget</a> that can edit
|
|
that TQVariant. For example if you have a TQVariant::String type, a
|
|
<a href="tqlineedit.html">TQLineEdit</a> would be the default editor returned, whereas a
|
|
TQVariant::Int's default editor would be a <a href="tqspinbox.html">TQSpinBox</a>.
|
|
<p> If you want to create different editors for fields with the same
|
|
data type, subclass TQEditorFactory and reimplement the
|
|
createEditor() function.
|
|
<p>See also <a href="database.html">Database Classes</a>.

|
|
<h3 class=fn><a name="TQEditorFactory"></a>TQEditorFactory::TQEditorFactory ( <a href="tqobject.html">TQObject</a> * parent = 0, const char * name = 0 )
|
|
</h3>
|
|
Constructs an editor factory with parent <em>parent</em>, called <em>name</em>.
|
|
|
|
<h3 class=fn><a name="~TQEditorFactory"></a>TQEditorFactory::~TQEditorFactory ()
|
|
</h3>
|
|
Destroys the object and frees any allocated resources.
|
|
|
|
<h3 class=fn><a href="tqwidget.html">TQWidget</a> * <a name="createEditor"></a>TQEditorFactory::createEditor ( <a href="tqwidget.html">TQWidget</a> * parent, const <a href="tqvariant.html">TQVariant</a> & v )<tt> [virtual]</tt>
|
|
</h3>
|
|
Creates and returns the appropriate editor for the <a href="tqvariant.html">TQVariant</a> <em>v</em>.
|
|
If the TQVariant is invalid, 0 is returned. The <em>parent</em> is passed
|
|
to the appropriate editor's constructor.
|
|
|
|
<p>Reimplemented in <a href="tqsqleditorfactory.html#createEditor">TQSqlEditorFactory</a>.
|
|
<h3 class=fn><a href="tqeditorfactory.html">TQEditorFactory</a> * <a name="defaultFactory"></a>TQEditorFactory::defaultFactory ()<tt> [static]</tt>
|
|
</h3>
|
|
Returns an instance of a default editor factory.
|
|
|
|
<h3 class=fn>void <a name="installDefaultFactory"></a>TQEditorFactory::installDefaultFactory ( <a href="tqeditorfactory.html">TQEditorFactory</a> * factory )<tt> [static]</tt>
|
|
</h3>
|
|
Replaces the default editor factory with <em>factory</em>.
|
|
<em>TQEditorFactory takes ownership of factory, and destroys it when it is no longer needed.</em>
