All popover sides have extra margins to possibly hold the tail, this is accounted for in gtk_popover_get_rect_coords(), and should be accounted for too in the tail position calculation. This fixes the gtk_render_frame_gap() warnings seen when a popover is pushed far too close to window sides.

|
* @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.
