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, set with Gtk::Widget::set_parent(). 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:

Member Function Documentation

◆ get_autohide()

bool Gtk::Popover::get_autohide ( ) const

Returns whether the popover is modal.

See set_autohide() for the implications of this.

Returns: true if popover is modal.

◆ get_cascade_popdown()

bool Gtk::Popover::get_cascade_popdown ( ) const

Returns whether the popover will close after a modal child is closed.

Returns: true if popover will close after a modal child.

◆ get_child() [1/2]

Widget * Gtk::Popover::get_child ( )

Gets the child widget of popover.

Returns: The child widget of popover.

◆ get_child() [2/2]

const Widget * Gtk::Popover::get_child ( ) const

Gets the child widget of popover.

Returns: The child widget of popover.

◆ get_has_arrow()

bool Gtk::Popover::get_has_arrow ( ) const

Gets whether this popover is showing an arrow pointing at the widget that it is relative to.

Returns: Whether the popover has an arrow.

◆ get_mnemonics_visible()

bool Gtk::Popover::get_mnemonics_visible ( ) const

Gets whether mnemonics are visible.

Returns: true if mnemonics are supposed to be visible in this popover.

◆ get_offset()

void Gtk::Popover::get_offset	(	int &	x_offset,
		int &	y_offset
	)		const

Gets the offset previous set with [metho.nosp@m.d@Gt.nosp@m.k.Pop.nosp@m.over.nosp@m..set_.nosp@m.offs.nosp@m.et()].

Parameters

x_offset	A location for the x_offset.
y_offset	A location for the y_offset.

◆ get_pointing_to()

bool Gtk::Popover::get_pointing_to ( Gdk::Rectangle & rect ) const

Gets the rectangle that the popover points to.

If a rectangle to point to has been set, this function will return true and fill in rect with such rectangle, otherwise it will return false and fill in rect with the parent widget coordinates.

Parameters

rect	Location to store the rectangle.

Returns: true if a rectangle to point to was set.

◆ get_position()

PositionType Gtk::Popover::get_position ( ) const

Returns the preferred position of popover.

Returns: The preferred position.

◆ get_type()

static GType Gtk::Popover::get_type ( )

static

Get the GType for this class, for use with the underlying GObject type system.

◆ gobj() [1/2]

GtkPopover * Gtk::Popover::gobj ( )

inline

Provides access to the underlying C GObject.

◆ gobj() [2/2]

const GtkPopover * Gtk::Popover::gobj ( ) const

inline

Provides access to the underlying C GObject.

◆ on_closed()

virtual void Gtk::Popover::on_closed ( )

protectedvirtual

This is a default handler for the signal signal_closed().

◆ operator=() [1/2]

Popover & Gtk::Popover::operator= ( const Popover & )

delete

◆ operator=() [2/2]

Popover & Gtk::Popover::operator= ( Popover && src )

noexcept

◆ popdown()

void Gtk::Popover::popdown ( )

Pops popover down.

This may have the side-effect of closing a parent popover as well. See property_cascade_popdown().

◆ popup()

void Gtk::Popover::popup ( )

Pops popover up.

◆ present()

void Gtk::Popover::present ( )

Allocate a size for the Gtk::Popover.

This function needs to be called in size-allocate by widgets who have a Gtk::Popover as child. When using a layout manager, this is happening automatically.

To make a popover appear on screen, use popup().

◆ property_autohide() [1/2]

Glib::PropertyProxy< bool > Gtk::Popover::property_autohide ( )

Whether to dismiss the popover on outside clicks.

Default value: true

Returns: A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

◆ property_autohide() [2/2]

Glib::PropertyProxy_ReadOnly< bool > Gtk::Popover::property_autohide ( ) const

Whether to dismiss the popover on outside clicks.

Default value: true

Returns: A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

◆ property_cascade_popdown() [1/2]

Glib::PropertyProxy< bool > Gtk::Popover::property_cascade_popdown ( )

Whether the popover pops down after a child popover.

This is used to implement the expected behavior of submenus.

Default value: false

Returns: A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

◆ property_cascade_popdown() [2/2]

Glib::PropertyProxy_ReadOnly< bool > Gtk::Popover::property_cascade_popdown ( ) const

Whether the popover pops down after a child popover.

This is used to implement the expected behavior of submenus.

Default value: false

Returns: A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

◆ property_child() [1/2]

Glib::PropertyProxy< Widget * > Gtk::Popover::property_child ( )

The child widget.

Returns: A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

◆ property_child() [2/2]

Glib::PropertyProxy_ReadOnly< Widget * > Gtk::Popover::property_child ( ) const

The child widget.

Returns: A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

◆ property_default_widget() [1/2]

Glib::PropertyProxy< Widget * > Gtk::Popover::property_default_widget ( )

The default widget inside the popover.
