gdk/surface: Replace move_to_rect() with GdkPopupLayout based API Replace the gdk_surface_move_to_rect() API with a new GdkSurface method called gdk_surface_present_popup() taking a new GdkPopupLayout object describing how they should be laid out on screen. The layout properties provided are the same as the ones used with gdk_surface_move_to_rect(), except they are now set up using GdkPopupLayout. Calling gdk_surface_present_popup() will either show the popup at the position described using the popup layout object and a new unconstrained size, or reposition it accordingly. In some situations, such as when a popup is set to autohide, presenting may immediately fail, in case the grab was not granted by the display server. After a successful present, the result of the layout can be queried using the following methods: * gdk_surface_get_position() - to get the position relative to its parent * gdk_surface_get_width() - to get the current width * gdk_surface_get_height() - to get the current height * gdk_surface_get_rect_anchor() - to get the anchor point on the anchor rectangle the popup was effectively positioned against given constraints defined by the environment and the layout rules provided via GdkPopupLayout. * gdk_surface_get_surface_anchor() - the same as the one above but for the surface anchor. A new signal replaces the old "moved-to-rect" one - "popup-layout-changed". However, it is only intended to be emitted when the layout changes implicitly by the windowing system, for example if the monitor resolution changed, or the parent window moved.

/**
* GdkAnchorHints:
* @GDK_ANCHOR_FLIP_X: allow flipping anchors horizontally
* @GDK_ANCHOR_FLIP_Y: allow flipping anchors vertically
* @GDK_ANCHOR_SLIDE_X: allow sliding surface horizontally
* @GDK_ANCHOR_SLIDE_Y: allow sliding surface vertically
* @GDK_ANCHOR_RESIZE_X: allow resizing surface horizontally
* @GDK_ANCHOR_RESIZE_Y: allow resizing surface vertically
* @GDK_ANCHOR_FLIP: allow flipping anchors on both axes
* @GDK_ANCHOR_SLIDE: allow sliding surface on both axes
* @GDK_ANCHOR_RESIZE: allow resizing surface on both axes
*
* Positioning hints for aligning a surface relative to a rectangle.
*
* These hints determine how the surface should be positioned in the case that
* the surface would fall off-screen if placed in its ideal position.
*
* For example, %GDK_ANCHOR_FLIP_X will replace %GDK_GRAVITY_NORTH_WEST with
* %GDK_GRAVITY_NORTH_EAST and vice versa if the surface extends beyond the left
* or right edges of the monitor.
*
* If %GDK_ANCHOR_SLIDE_X is set, the surface can be shifted horizontally to fit
* on-screen. If %GDK_ANCHOR_RESIZE_X is set, the surface can be shrunken
* horizontally to fit.
*
* In general, when multiple flags are set, flipping should take precedence over
* sliding, which should take precedence over resizing.
