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.

bool Gtk::Popover::get_pointing_to | ( | Gdk::Rectangle& | rect | ) | const |
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 attached widget coordinates.
- Parameters
-
rect Location to store the rectangle.
- Returns
true
if a rectangle to point to was set.

If you want to hide the popover without a transition, use Gtk::Widget::hide().
void Gtk::Popover::popup | ( | ) |
Pops popover up.
This is different than a Gtk::Widget::show() call in that it shows the popover with a transition. If you want to show the popover without a transition, use Gtk::Widget::show().
void Gtk::Popover::present | ( | ) |
Presents the popover to the user.
