## Functions

### _init ()

    _init (St.Widget   sourceActor,
           St.Side     orientation);

#### Parameters

sourceActor | the actor that owns the popup menu |
orientation | the side of the menu that will be attached to `sourceActor`. See `setOrientation()` for details |

### setArrowSide ()

    setArrowSide (St.Side   side);

Sets the orientation of the `sourceActor` with respect to the menu. This function is deprecated and kept for compatibility with older code. Please use `setOrientation` instead.

#### Parameters

side | The new side of the menu |

### setOrientation ()

    setOrientation (St.Side   orientation);

Sets the orientation of the `sourceActor` with respect to the menu. For example, if you use St.Side.TOP, the menu will try to place itself below the `sourceActor` unless there is not enough room for it.

#### Parameters

orientation | The new orientation of the menu |

### setCustomStyleClass ()

    setCustomStyleClass (string   className);

Adds a custom class name to the menu which allows it to be styled separately from other menus.

#### Parameters

className | the custom class name to add |

### setSourceAlignment ()

    setSourceAlignment (real   alignment);

Since the boxpointer was removed from the menu, this function now does nothing. Please do not use this function in new code.

#### Parameters

alignment | the position of the arrow relative to the source actor. |

### getPanel ()

    getPanel ();

`returns` panel (Clutter.Actor | null) actor of the panel this menu is on, or null if it is not on a panel

### open ()

    open (boolean   animate);

Opens the popup menu

#### Parameters

animate | whether to animate the open effect or not |

### close ()

    close (boolean   animate);

Closes the popup menu.

#### Parameters

animate | whether to animate the close effect or not |

### shiftToPosition ()

    shiftToPosition (number   slidePosition);

This function specifies a new position at which to center the menu. The position is given in coordinates relative to the `sourceActor`, and as such should always be positive. This is useful if, for example, you want the menu to open at the location of a mouse click rather than at the center of the actor. This function only moves the menu along one axis as determined by the orientation of the menu, so that the menu is always attached to the `sourceActor`. For example, if the orientation is set to St.Side.TOP, this function will move the center along the x axis. If you have set the `slidePosition` using this function and then wish to return to centering the menu on the center of the `sourceActor`, you can do so by setting it to -1.

#### Parameters

slidePosition | Position relative to the `sourceActor` of the menu upon which the menu will be centered (if possible). If -1, the menu will be centered on the `sourceActor`. |

### setMaxHeight ()

    setMaxHeight ();

This function is called internally to set the max-height and max-width properties of the popup menu such that it does not grow to a size larger than the monitor. Individual popup menus can override this method to change the max height/width if they really want to.

Note that setting the max-height won't do any good if the minimum height of the menu is higher then the screen; it's useful if part of the menu is scrollable so the minimum height is smaller than the natural height.
