# PopupApplet Class Reference

`from PyKDE4.plasma import *`

Inherits: Plasma.Applet → QGraphicsWidget → QObject
Namespace: Plasma

## Detailed Description

Allows applets to automatically 'collapse' into an icon when put in an panel, and is a convenient base class for any applet that wishes to use extenders.

Applets that subclass this class should implement either widget() or graphicsWidget() to return a widget that will be displayed in the applet if the applet is in a Planar or MediaCenter form factor. If the applet is put in a panel, an icon will be displayed instead, which shows the widget in a popup when clicked.

If you use this class as a base class for your extender using applet, the extender will automatically be used for the popup; reimplementing graphicsWidget() is unnecessary in this case. If you need a popup that does not steal window focus when openend or used, set window flag Qt.X11BypassWindowManagerHint the widget returned by widget() or graphicsWidget().

## Method Documentation

__init__ | ( | self, |
|  | QObject | parent,
|  | [QVariant] | args
| ) |  |  |

__init__ | ( | self, |
|  | QString | packagePath,
|  | long | appletId,
|  | [QVariant] | args
| ) |  |  |

Internal:
  This constructor is to be used with the Package loading system.

Parameters:

  | parent | a QObject parent; you probably want to pass in 0
  | args | a list of strings containing two entries: the service id and the applet id

Since:
  4.3

dragEnterEvent | ( | self, |
|  | QGraphicsSceneDragDropEvent | event
| ) |  |  |

Reimplemented from QGraphicsLayoutItem

dragLeaveEvent | ( | self, |
|  | QGraphicsSceneDragDropEvent | event
| ) |  |  |

Reimplemented from QGraphicsLayoutItem

dropEvent | ( | self, |
|  | QGraphicsSceneDragDropEvent | event
| ) |  |  |

Reimplemented from QGraphicsLayoutItem

bool eventFilter | ( | self, |
|  | QObject | watched,
|  | QEvent | event
| ) |  |  |

Reimplemented from QGraphicsLayoutItem

QGraphicsWidget graphicsWidget | ( |  | self ) |

Implement either this function or widget().

Returns:
  the widget that will get shown in either a layout, in the applet or in a Dialog, depending on the form factor of the applet. If you set a popup icon you must also set a minimum size of the applet. When the applet is smaller than this minimum size, it will be displayed as that icon.

hidePopup | ( |  | self ) |

Hides the popup.

bool isIconified | ( |  | self ) |

Returns:
  true if the applet is collapsed to an icon

Since:
  4.6

bool isPassivePopup | ( |  | self ) |

Returns:
  true if the dialog will be treated as a passive poup

bool isPopupShowing | ( |  | self ) |

Returns:
  true if the applet is popped up

mousePressEvent | ( | self, |
|  | QGraphicsSceneMouseEvent | event
| ) |  |  |

Reimplemented from QGraphicsLayoutItem

mouseReleaseEvent | ( | self, |
|  | QGraphicsSceneMouseEvent | event
| ) |  |  |

Reimplemented from QGraphicsLayoutItem

Qt::AlignmentFlag popupAlignment | ( |  | self ) |

Returns:
  the default alignment of the popup relative to the applet

Since:
  4.6

popupEvent | ( | self, |
|  | bool | show
| ) |  |  |

This event handler can be reimplemented in a subclass to receive an event before the popup is shown or hidden.

Parameters:

  | show | true if the popup is going to be shown, false if the popup is going to be hidden. Note that showing and hiding the popup on click is already done in PopupApplet.

QIcon popupIcon | ( |  | self ) |

Returns:
  the icon that is displayed when the applet is in a panel.

Plasma.PopupPlacement popupPlacement | ( |  | self ) |

Returns:
  the placement of the popup relating to the applet

setGraphicsWidget | ( | self, |
|  | QGraphicsWidget | widget
| ) |  |  |

setPassivePopup | ( | self, |
|  | bool | passive
| ) |  |  |

Sets whether or not the dialog popup that gets created should be a "passive" popup that does not steal focus from other windows or not.

Parameters:

  | passive | true if the dialog should be treated as a passive popup

setPopupAlignment | ( | self, |
|  | Qt::AlignmentFlag | alignment
| ) |  |  |

Sets the default alignment of the popup relative to the applet

Parameters:

  | alignment | the alignment to use; Qt.AlignLeft or Qt.AlignRight

Since:
  4.6

setPopupIcon | ( | self, |
|  | QIcon | icon
| ) |  |  |

Parameters:

  | icon | the icon that has to be displayed when the applet is in a panel. Passing in an empty QString() means that the popup applet itself will provide an interface for when the PopupApplet is not showing the widget() or graphicsWidget() directly.

If you set a popup icon you must also set a minimum size of the applet. When the applet is smaller than this minimum size, it will be displayed as that icon.

setPopupIcon | ( | self, |
|  | QString | iconName
| ) |  |  |

Parameters:

  | icon | the icon that has to be displayed when the applet is in a panel. Passing in an empty QString() means that the popup applet itself will provide an interface for when the PopupApplet is not showing the widget() or graphicsWidget() directly.

If you set a popup icon you must also set a minimum size of the applet. When the applet is smaller than this minimum size, it will be displayed as that icon.

setWidget | ( | self, |
|  | QWidget | widget
| ) |  |  |

showPopup | ( | self, |
|  | long | displayTime=0
| ) |  |  |

Shows the dialog showing the widget if the applet is in a panel.

Parameters:

  | displayTime | the time in ms that the popup should be displayed, defaults to 0 which means always (until the user closes it again, that is).

QSizeF sizeHint | ( | self, |
|  | Qt::SizeHint | which,
|  | QSizeF | constraint=QSizeF()
| ) |  |  |

Reimplemented from QGraphicsLayoutItem

timerEvent | ( | self, |
|  | QTimerEvent | event
| ) |  |  |

Reimplemented from QGraphicsLayoutItem

togglePopup | ( |  | self ) |

Toggles the popup.

QWidget widget | ( |  | self ) |

Implement either this function or graphicsWidget().

Returns:
  the widget that will get shown in either a layout, in the applet or in a Dialog, depending on the form factor of the applet.
