Detailed Description

Context dependent bubbles.

Gtk::Popover is a bubble-like context window, primarily meant to provide context-dependent information or options. Popovers are attached to a widget, passed at construction time on Gtk::Popover(), or updated afterwards through Gtk::Popover::set_relative_to(), by default they will point to the whole widget area, although this behavior can be changed through Gtk::Popover::set_pointing_to().

The position of a popover relative to the widget it is attached to can also be changed through Gtk::Popover::set_position().

By default, Gtk::Popover performs a GTK grab, in order to ensure input events get redirected to it while it is shown, and also so the popover is dismissed in the expected situations (clicks outside the popover, or the Esc key being pressed). If no such modal behavior is desired on a popover, Gtk::Popover::set_autohide() may be called on it to tweak its behavior.

Since gtkmm 3.12:

void Gtk::Popover::set_autohide ( bool  autohide = true)

Sets whether popover is modal.

A modal popover will grab the keyboard focus on it when being displayed. Clicking outside the popover area or pressing Esc will dismiss the popover.

Parameters
autohide#true to dismiss the popover on outside clicks.
void Gtk::Popover::set_default_widget ( Widget widget)
void Gtk::Popover::set_has_arrow ( bool  has_arrow = true)

Sets whether this popover should draw an arrow pointing at the widget it is relative to.

Parameters
has_arrowtrue to draw an arrow.
void Gtk::Popover::set_pointing_to ( const Gdk::Rectangle rect)

Sets the rectangle that popover will point to, in the coordinate space of the widget popover is attached to, see set_relative_to().

Parameters
rectRectangle to point to.
void Gtk::Popover::set_position ( PositionType  position = PositionType::TOP)

Sets the preferred position for popover to appear.

If the popover is currently visible, it will be immediately updated.

This preference will be respected where possible, although on lack of space (eg. if close to the window edges), the Gtk::Popover may choose to appear on the opposite side

Parameters
positionPreferred popover position.
void Gtk::Popover::set_relative_to ( const Widget relative_to)

Sets a new widget to be attached to popover.

If popover is visible, the position will be updated.

Note
the ownership of popovers is always given to their relative_to widget, so if relative_to is set to nullptr on an attached popover, it will be detached from its previous widget, and consequently destroyed unless extra references are kept.
Parameters
relative_toA Gtk::Widget.
