|

| 57 |
|
|---|
| 58 |
|
|---|
| 59 | The QSignalMapper class bundles signals from identifiable senders.
|
|---|
| 60 | <p>
|
|---|
| 61 | <p> This class collects a set of parameterless signals, and re-emits
|
|---|
| 62 | them with integer or string parameters corresponding to the object
|
|---|
| 63 | that sent the signal.
|
|---|
| 64 | <p>See also <a href="io.html">Input/Output and Networking</a>.
|

| 65 |
|

| 66 | <hr><h2>Member Function Documentation</h2>
|
|---|
| 67 | <h3 class=fn><a name="QSignalMapper"></a>QSignalMapper::QSignalMapper ( <a href="qobject.html">QObject</a> * parent, const char * name = 0 )
|
|---|
| 68 | </h3>
|
|---|
| 69 | Constructs a QSignalMapper called <em>name</em>, with parent <em>parent</em>.
|
|---|
| 70 | Like all QObjects, it will be deleted when the parent is deleted.
|
|---|
| 71 |
|
|---|
| 72 | <h3 class=fn><a name="~QSignalMapper"></a>QSignalMapper::~QSignalMapper ()
|
|---|
| 73 | </h3>
|
|---|
| 74 | Destroys the QSignalMapper.
|
|---|
| 75 |
|
|---|
| 76 | <h3 class=fn>void <a name="map"></a>QSignalMapper::map ()<tt> [slot]</tt>
|
|---|
| 77 | </h3>
|
|---|
| 78 | This slot emits signals based on which object sends signals to it.
|
|---|
| 79 |
|
|---|
| 80 | <p>Examples: <a href="i18n-example.html#x1945">i18n/main.cpp</a> and <a href="themes-example.html#x334">themes/themes.cpp</a>.
|
|---|
| 81 | <h3 class=fn>void <a name="mapped"></a>QSignalMapper::mapped ( int )<tt> [signal]</tt>
|
|---|
| 82 | </h3>
|
|---|
| 83 |
|
|---|
| 84 | <p> This signal is emitted when <a href="#map">map</a>() is signaled from an object that
|
|---|
| 85 | has an integer mapping set.
|
|---|
| 86 | <p> <p>See also <a href="#setMapping">setMapping</a>().
|
|---|
| 87 |
|
|---|
| 88 | <p>Examples: <a href="i18n-example.html#x1946">i18n/main.cpp</a> and <a href="themes-example.html#x335">themes/themes.cpp</a>.
|
|---|
| 89 | <h3 class=fn>void <a name="mapped-2"></a>QSignalMapper::mapped ( const <a href="qstring.html">QString</a> & )<tt> [signal]</tt>
|
|---|
| 90 | </h3>
|
|---|
| 91 | This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
|
|---|
| 92 | <p> This signal is emitted when <a href="#map">map</a>() is signaled from an object that
|
|---|
| 93 | has a string mapping set.
|
|---|
| 94 | <p> <p>See also <a href="#setMapping">setMapping</a>().
|
|---|
| 95 |
|
|---|
| 96 | <h3 class=fn>void <a name="removeMappings"></a>QSignalMapper::removeMappings ( const <a href="qobject.html">QObject</a> * sender )
|
|---|
| 97 | </h3>
|
|---|
| 98 | Removes all mappings for <em>sender</em>. This is done automatically
|
|---|
| 99 | when mapped objects are destroyed.
|
|---|
| 100 |
|
|---|
| 101 | <h3 class=fn>void <a name="setMapping"></a>QSignalMapper::setMapping ( const <a href="qobject.html">QObject</a> * sender, int identifier )<tt> [virtual]</tt>
|
|---|
| 102 | </h3>
|
|---|
| 103 | Adds a mapping so that when <a href="#map">map</a>() is signaled from the given <em>sender</em>, the signal <a href="#mapped">mapped</a>(<em>identifier</em>) is emitted.
|
|---|
| 104 | <p> There may be at most one integer identifier for each object.
|
|---|
| 105 |
|
|---|
| 106 | <p>Examples: <a href="i18n-example.html#x1947">i18n/main.cpp</a> and <a href="themes-example.html#x336">themes/themes.cpp</a>.
|
|---|
| 107 | <h3 class=fn>void <a name="setMapping-2"></a>QSignalMapper::setMapping ( const <a href="qobject.html">QObject</a> * sender, const <a href="qstring.html">QString</a> & identifier )<tt> [virtual]</tt>
|
|---|
| 108 | </h3>
|
|---|
| 109 | This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
|
|---|
| 110 | <p> Adds a mapping so that when <a href="#map">map</a>() is signaled from the given <em>sender</em>, the signal mapper(<em>identifier</em>) is emitted.
|
|---|
| 111 | <p> There may be at most one string identifier for each object, and it
|
|---|
| 112 | may not be empty.
