<h1>KConfigDialog Class Reference</h1>
<code>from PyKDE4.kdeui import *</code>
<p>
Inherits: <a href="../kdeui/KPageDialog.html">KPageDialog</a> → <a href="../kdeui/KDialog.html">KDialog</a> → QDialog → QWidget → QObject<br />
<h2>Detailed Description</h2>
<p>Standard KDE configuration dialog class
</p>
<p>
The KConfigDialog class provides an easy and uniform means of displaying
a settings dialog using KPageDialog, KConfigDialogManager and a
KConfigSkeleton derived settings class.
</p>
<p>
KConfigDialog handles the enabling and disabling of buttons, creation
of the dialog, and deletion of the widgets. Because of
KConfigDialogManager, this class also manages: restoring
the settings, reseting them to the default values, and saving them. This
requires that the names of the widgets corresponding to configuration entries
have to have the same name plus an additional "kcfg_" prefix. For example the
widget named "kcfg_MyOption" would be associated with the configuration entry
"MyOption".
</p>
<p>
Here is an example usage of KConfigDialog:
</p>
<p>
<pre class="fragment">
void KCoolApp.showSettings(){
if(KConfigDialog.showDialog("settings"))
return;
KConfigDialog *dialog = new KConfigDialog(this, "settings", MySettings.self());
dialog->setFaceType(KPageDialog.List);
dialog->addPage(new General(0, "General"), i18n("General") );
dialog->addPage(new Appearance(0, "Style"), i18n("Appearance") );
connect(dialog, SIGNAL(settingsChanged(const QString&)), mainWidget, SLOT(loadSettings()));
connect(dialog, SIGNAL(settingsChanged(const QString&)), this, SLOT(loadSettings()));
dialog->show();
}
</pre>
</p>
<p>
Other than the above code, each class that has settings in the dialog should
have a loadSettings() type slot to read settings and perform any
necessary changes.
</p>
<p>
