Member Function Documentation

advise_focus_gained()

void miral::CanonicalWindowManagerPolicy::advise_focus_gained ( WindowInfo const & info )

overridevirtual

Raises the window (and any children).

Reimplemented from miral::WindowManagementPolicy.

Reimplemented in KioskWindowManagerPolicy.

confirm_inherited_move()

auto miral::CanonicalWindowManagerPolicy::confirm_inherited_move ( WindowInfo const & window_info, Displacement movement )->Rectangle

overridevirtual

Move the child window with the parent.

Implements miral::WindowManagementPolicy.

confirm_placement_on_display()

auto miral::CanonicalWindowManagerPolicy::confirm_placement_on_display ( WindowInfo const & window_info, MirWindowState new_state, Rectangle const & new_placement )->Rectangle

overridevirtual

Confirm (and optionally adjust) the placement of a window on the display.

Called when (re)placing fullscreen, maximized, horizontally maximised and vertically maximized windows to allow adjustment for decorations.

Parameters

window_info	the window
new_state	the new state
new_placement	the suggested placement

Returns

the confirmed placement of the window

Implements miral::WindowManagementPolicy.

handle_modify_window()

void miral::CanonicalWindowManagerPolicy::handle_modify_window ( WindowInfo & window_info, WindowSpecification const & modifications )

overridevirtual

Applies the requested modifications.

Implements miral::WindowManagementPolicy.

Reimplemented in KioskWindowManagerPolicy.

handle_raise_window()

void miral::CanonicalWindowManagerPolicy::handle_raise_window ( WindowInfo & window_info )

overridevirtual

Tries to focus on the newly ready window.

Implements miral::WindowManagementPolicy.

handle_request_drag_and_drop()

void miral::CanonicalWindowManagerPolicy::handle_request_drag_and_drop ( WindowInfo & window_info )

overridevirtual

request from client to initiate drag and drop

Note

this is a legacy of Unity8's content-hub and should probably be ignored going forward

Implements miral::WindowManagementPolicy.

Reimplemented in KioskWindowManagerPolicy.

handle_window_ready()

void miral::CanonicalWindowManagerPolicy::handle_window_ready ( WindowInfo & window_info )

overridevirtual

Tries to focus on the newly ready window.

Implements miral::WindowManagementPolicy.

place_new_window()

virtual auto miral::CanonicalWindowManagerPolicy::place_new_window ( ApplicationInfo const & app_info, WindowSpecification const & requested_specification )->WindowSpecification

overridevirtual

Customize initial window placement.

Parameters

app_info	the application requesting a new window
requested_specification	the requested specification (updated with default placement)

Returns

the customized specification

Implements miral::WindowManagementPolicy.
