std::function<void()>&zxdg_positioner_v6_t::on_destroy()

std::function<void(zxdg_positioner_v6_anchor)>&zxdg_positioner_v6_t::on_set_anchor()
set anchor rectangle anchor edges
Parametersanchor bit mask of anchor edges
Defines a set of edges for the anchor rectangle. These are used to derive an anchor point that the child
surface will be positioned relative to. If two orthogonal edges are specified (e.g. 'top' and 'left'),
then the anchor point will be the intersection of the edges (e.g. the top left position of the
rectangle); otherwise, the derived anchor point will be centered on the specified edge, or in the center
of the anchor rectangle if no edge is specified.
If two parallel anchor edges are specified (e.g. 'left' and 'right'), the invalid_input error is raised.

std::function<void(int32_t,int32_t,int32_t,int32_t)>&zxdg_positioner_v6_t::on_set_anchor_rect()
set the anchor rectangle within the parent surface
Parametersx x position of anchor rectangle
y y position of anchor rectangle
width width of anchor rectangle
height height of anchor rectangle
Specify the anchor rectangle within the parent surface that the child surface will be placed relative to.
The rectangle is relative to the window geometry as defined by xdg_surface.set_window_geometry of the
parent surface. The rectangle must be at least 1x1 large.
When the xdg_positioner object is used to position a child surface, the anchor rectangle may not extend
outside the window geometry of the positioned child's parent surface.
If a zero or negative size is set the invalid_input error is raised.

std::function<void(zxdg_positioner_v6_constraint_adjustment)>&zxdg_positioner_v6_t::on_set_constraint_adjustment()
set the adjustment to be done when constrained
Parametersconstraint_adjustment bit mask of constraint adjustments
Specify how the window should be positioned if the originally intended position caused the surface to be
constrained, meaning at least partially outside positioning boundaries set by the compositor. The
adjustment is set by constructing a bitmask describing the adjustment to be made when the surface is
constrained on that axis.
If no bit for one axis is set, the compositor will assume that the child surface should not change its
position on that axis when constrained.
If more than one bit for one axis is set, the order of how adjustments are applied is specified in the
corresponding adjustment descriptions.
The default adjustment is none.

std::function<void(zxdg_positioner_v6_gravity)>&zxdg_positioner_v6_t::on_set_gravity()
set child surface gravity
Parametersgravity bit mask of gravity directions
Defines in what direction a surface should be positioned, relative to the anchor point of the parent
surface. If two orthogonal gravities are specified (e.g. 'bottom' and 'right'), then the child surface
will be placed in the specified direction; otherwise, the child surface will be centered over the anchor
point on any axis that had no gravity specified.
If two parallel gravities are specified (e.g. 'left' and 'right'), the invalid_input error is raised.

std::function<void(int32_t,int32_t)>&zxdg_positioner_v6_t::on_set_offset()
set surface position offset
Parametersx surface position x offset
y surface position y offset
Specify the surface position offset relative to the position of the anchor on the anchor rectangle and
the anchor on the surface. For example if the anchor of the anchor rectangle is at (x, y), the surface
has the gravity bottom|right, and the offset is (ox, oy), the calculated surface position will be (x +
ox, y + oy). The offset position of the surface is the one used for constraint testing. See
set_constraint_adjustment.
An example use case is placing a popup menu on top of a user interface element, while aligning the user
interface element of the parent surface with some user interface element placed somewhere in the popup
surface.

std::function<void(int32_t,int32_t)>&zxdg_positioner_v6_t::on_set_size()
set the size of the to-be positioned rectangle
Parameterswidth width of positioned rectangle
height height of positioned rectangle
Set the size of the surface that is to be positioned with the positioner object. The size is in surface-
local coordinates and corresponds to the window geometry. See xdg_surface.set_window_geometry.
If a zero or negative size is set the invalid_input error is raised.

voidwayland::server::resource_t::post_no_memory()const[inherited]
Post 'not enough memory' error to the client
If the compositor has not enough memory to fulfill a certail request of the client, this function can be
called to notify the client of this circumstance.

Returns
true if there is an underlying object, false if this wrapper is empty
