|
* @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.
