Method Details

getType

static Type getType()

Get the GType of the Popup class

Returns:

the GType

getAutohide

default boolean getAutohide()

Returns whether this popup is set to hide on outside clicks.

Returns:

true if this Popup will autohide

getParent

default Surface getParent()

Returns the parent surface of a popup.

Returns:

the parent surface

getPositionX

default int getPositionX()

Obtains the position of the popup relative to its parent.

Returns:

the X coordinate of this Popup position

getPositionY

default int getPositionY()

Obtains the position of the popup relative to its parent.

Returns:

the Y coordinate of this Popup position

getRectAnchor

default Gravity getRectAnchor()

Gets the current popup rectangle anchor.

The value returned may change after calling present(int, int, org.gnome.gdk.PopupLayout), or after the Gdk.Surface::layout signal is emitted.

Returns:

the current rectangle anchor value of this Popup

getSurfaceAnchor

default Gravity getSurfaceAnchor()

Gets the current popup surface anchor.

The value returned may change after calling present(int, int, org.gnome.gdk.PopupLayout), or after the Gdk.Surface::layout signal is emitted.

Returns:

the current surface anchor value of this Popup

present

default boolean present(int width,
 int height,
 PopupLayout layout)

Present this Popup after having processed the GdkPopupLayout rules.

If the popup was previously not showing, it will be shown, otherwise it will change position according to layout.

After calling this function, the result should be handled in response to the Gdk.Surface::layout signal being emitted. The resulting popup position can be queried using getPositionX(), getPositionY(), and the resulting size will be sent as parameters in the layout signal. Use getRectAnchor() and getSurfaceAnchor() to get the resulting anchors.

Presenting may fail, for example if the this Popup is set to autohide and is immediately hidden upon being presented. If presenting failed, the Gdk.Surface::layout signal will not me emitted.

Parameters:

width - the unconstrained popup width to layout

height - the unconstrained popup height to layout

layout - the GdkPopupLayout object used to layout

Returns:

false if it failed to be presented, otherwise true.
