## Signal Documentation

cleared | ( |  | ) |

Signal syntax:
  `QObject.connect(source, SIGNAL("cleared()"), target_slot)`

findAheadActive | ( | bool | a0
| ) |  |  |

Signal syntax:
  `QObject.connect(source, SIGNAL("findAheadActive(bool)"), target_slot)`

finishedLayout | ( |  | ) |

This signal is used for internal layouting. Don't use it to check if rendering finished. Use KHTMLPart completed() signal instead.

Signal syntax:
  `QObject.connect(source, SIGNAL("finishedLayout()"), target_slot)`

hideAccessKeys | ( |  | ) |

Signal syntax:
  `QObject.connect(source, SIGNAL("hideAccessKeys()"), target_slot)`

repaintAccessKeys | ( |  | ) |

Signal syntax:
  `QObject.connect(source, SIGNAL("repaintAccessKeys()"), target_slot)`

zoomView | ( | int | a0
| ) |  |  |

Signal syntax:
