GI.Gtk.Objects.Popover

GtkPopover is a bubble-like context popup.

It is primarily meant to provide context-dependent information or options. Popovers are attached to a parent widget. By default, they point to the whole widget area, although this behavior can be changed with popoverSetPointingTo.

The position of a popover relative to the widget it is attached to can also be changed with popoverSetPosition

By default, GtkPopover performs a 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 Escape key being pressed). If no such modal behavior is desired on a popover, popoverSetAutohide may be called on it to tweak its behavior.

GtkPopover as menu replacement

GtkPopover is often used to replace menus. The best was to do this is to use the PopoverMenu subclass which supports being populated from a GMenuModel with popoverMenuNewFromModel.

CSS nodes

popover.background[.menu]
├── arrow
╰── contents
    ╰── <child>

GtkPopover has a main node with name popover, an arrow with name arrow, and another node for the content named contents. The popover node always gets the .background style class. It also gets the .menu style class if the popover is menu-like, e.g. is a PopoverMenu.

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. The visible part of the popover can have a shadow. To specify it in CSS, set the box-shadow of the contents node.

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 and shadow, 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.

These values are used when preparing the [structgdk.PopupLayout] for positioning the popover.

setPointingTo

popoverSetPointingTo

Arguments

:: (HasCallStack, MonadIO m, IsPopover a)

=> a

popover: a GtkPopover

=> a

popover: a GtkPopover

-> PositionType

position: preferred popover position

-> m ()

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 GtkPopover may choose to appear on the opposite side.

Signals

activateDefault

afterPopoverClosed :: (IsPopover a, MonadIO m) => a -> ((?self :: a) => PopoverClosedCallback) -> m SignalHandlerId

Connect a signal handler for the closed signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after popover #closed callback

By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

onPopoverClosed :: (IsPopover a, MonadIO m) => a -> ((?self :: a) => PopoverClosedCallback) -> m SignalHandlerId
