This has been broken since we switched key event delivery to follow the same semantics than pointer/touch. There, GTK+ grabs will influence the topmost widget during event delivery, rendering the toplevel unable to handle key navigation. The toplevel must handle those key events in an explicit manner then. We don't render the keyboard focus rectangle yet, but I assume that's something else.

|
|
* @Short_description: Context dependent bubbles
|
|
* @Title: GtkPopover
|
|
*
|
|
* GtkPopover 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_new(),
|
|
* 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, #GtkPopover 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_modal() may be called on it
|
|
* to tweak its behavior.
|
|
*
|
|
* ## GtkPopover as menu replacement
|
|
*
|
|
* GtkPopover is often used to replace menus. To facilitate this, it
|
|
* supports being populated from a #GMenuModel, using
|
|
* gtk_popover_new_from_model(). In addition to all the regular menu
|
|
* model features, this function supports rendering sections in the
|
|
* model in a more compact form, as a row of icon buttons instead of
|
|
* menu items.
|
|
*
|
|
* To use this rendering, set the ”display-hint” attribute of the
|
|
* section to ”horizontal-buttons” and set the icons of your items
|
|
* with the ”verb-icon” attribute.
|

* # CSS nodes
|
|
*
|
|
* |[<!-- language="plain" -->
|
|
* popover
|
|
* ├── arrow
|
|
* ╰── contents.background[.menu]
|
|
* ╰── <child>
|
|
* ]|
|
|
*
|
|
* The contents child node always gets the .background style class and it
|
|
* gets the .menu style class if the popover is menu-like (e.g. #GtkPopoverMenu
|
|
* or created using gtk_popover_new_from_model()).
|
|
*
|
|
* Particular uses of GtkPopover, such as touch selection popups
|
|
* or magnifiers in #GtkEntry or #GtkTextView get style classes
|
|
* like .touch-selection or .magnifier to differentiate from
|
|
* plain popovers.
|
|
*
|
|
* When styling a popover directly, the popover node should usually not have any
|
|
* background.
|
|
*
|
|
* Note that, in order to accomplish appropriate arrow visuals, #GtkPopover uses
|
|
* custom drawing for the arrow node. This makes it possible for the arrow to change
|
|
* its shape dynamically, but it also limits the possibilities of styling it using CSS.
|
|
* In particular, the arrow gets drawn over the content node's border so they look
|
|
* like one shape, which means that the border-width of the content node and the arrow
|
|
* node should be the same. The arrow also does not support any border shape other than
|
|
* solid, no border-radius, only one border width (border-bottom-width is used) and no box-shadow.
