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:

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.

How to place the popover, relative to its parent.

Default value: Gtk::PositionType::BOTTOM

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

◆ set_autohide()

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. Focus will wrap around within the popover. Clicking outside the popover area or pressing Esc will dismiss the popover.

Called this function on an already showing popup with a new autohide value different from the current one, will cause the popup to be hidden.

Parameters

autohide true to dismiss the popover on outside clicks.

◆ set_cascade_popdown()

void Gtk::Popover::set_cascade_popdown ( bool cascade_popdown = true )

If cascade_popdown is true, the popover will be closed when a child modal popover is closed.

If false, popover will stay visible.

Parameters

cascade_popdown true if the popover should follow a child closing.

◆ set_child()

void Gtk::Popover::set_child ( Widget & child )

Sets the child widget of popover.

Parameters

child The child widget.

◆ set_default_widget()

void Gtk::Popover::set_default_widget ( Widget & widget )

Sets the default widget of a Gtk::Popover.

The default widget is the widget that’s activated when the user presses Enter in a dialog (for example). This function sets or unsets the default widget for a Gtk::Popover.

Parameters

widget A child widget of popover to set as the default, or nullptr to unset the default widget for the popover.

◆ set_has_arrow()

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_arrow true to draw an arrow.

◆ set_mnemonics_visible()

void Gtk::Popover::set_mnemonics_visible ( bool mnemonics_visible = true )

Sets whether mnemonics should be visible.

Parameters

mnemonics_visible The new value.

◆ set_offset()

void Gtk::Popover::set_offset	(	int	x_offset,
		int	y_offset
	)

Sets the offset to use when calculating the position of the popover.

These values are used when preparing the Gdk::PopupLayout for positioning the popover.

Parameters

x_offset	The x offset to adjust the position by.
y_offset	The y offset to adjust the position by.

◆ set_pointing_to()

void Gtk::Popover::set_pointing_to ( const Gdk::Rectangle & rect )

Sets the rectangle that popover points to.

This is in the coordinate space of the popover parent.

Parameters

rect	Rectangle to point to.

◆ set_position()

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

position Preferred popover position.

◆ signal_closed()

Glib::SignalProxy< void()> Gtk::Popover::signal_closed ( )

Slot Prototype:: void on_my_closed()
