voidshell_surface_t::configure(shell_surface_resizeconst&edges,int32_twidth,int32_theight,boolpost=true)
suggest resize
Parametersedges how the surface was resized
width new width of the surface
height new height of the surface
The configure event asks the client to resize its surface.
The size is a hint, in the sense that the client is free to ignore it if it doesn't resize, pick a
smaller size (to satisfy aspect ratio or resize in steps of NxM pixels).
The edges parameter provides a hint about how the surface was resized. The client may use this
information to decide how to adjust its content to the new size (e.g. a scrolling area might adjust its
content position to leave the viewable content unmoved).
The client is free to dismiss all but the last configure event it received.
The width and height arguments specify the size of the window in surface-local coordinates.

std::function<void(seat_t,uint32_t)>&shell_surface_t::on_move()
start an interactive move
Parametersseat seat whose pointer is used
serial serial number of the implicit grab on the pointer
Start a pointer-driven move of the surface.
This request must be used in response to a button press event. The server may ignore move requests
depending on the state of the surface (e.g. fullscreen or maximized).

std::function<void(std::string)>&shell_surface_t::on_set_class()
set surface class
Parametersclass_ surface class
Set a class for the surface.
The surface class identifies the general class of applications to which the surface belongs. A common
convention is to use the file name (or the full path if it is a non-standard location) of the
application's .desktop file as the class.

std::function<void(shell_surface_fullscreen_method,uint32_t,output_t)>&shell_surface_t::on_set_fullscreen()
make the surface a fullscreen surface
Parametersmethod method for resolving size conflict
framerate framerate in mHz
output output on which the surface is to be fullscreen
Map the surface as a fullscreen surface.
If an output parameter is given then the surface will be made fullscreen on that output. If the client
does not specify the output then the compositor will apply its policy - usually choosing the output on
which the surface has the biggest surface area.
The client may specify a method to resolve a size conflict between the output size and the surface size -
this is provided through the method parameter.
The framerate parameter is used only when the method is set to 'driver', to indicate the preferred
framerate. A value of 0 indicates that the client does not care about framerate. The framerate is
specified in mHz, that is framerate of 60000 is 60Hz.
A method of 'scale' or 'driver' implies a scaling operation of the surface, either via a direct scaling
operation or a change of the output mode. This will override any kind of output scaling, so that mapping
a surface with a buffer size equal to the mode can fill the screen independent of buffer_scale.
A method of 'fill' means we don't scale up the buffer, however any output scale is applied. This means
that you may run into an edge case where the application maps a buffer with the same size of the output
mode but buffer_scale 1 (thus making a surface larger than the output). In this case it is allowed to
downscale the results to fit the screen.
The compositor must reply to this request with a configure event with the dimensions for the output on
which the surface will be made fullscreen.

std::function<void(output_t)>&shell_surface_t::on_set_maximized()
make the surface a maximized surface
Parametersoutput output on which the surface is to be maximized
Map the surface as a maximized surface.
If an output parameter is given then the surface will be maximized on that output. If the client does not
specify the output then the compositor will apply its policy - usually choosing the output on which the
surface has the biggest surface area.
The compositor will reply with a configure event telling the expected new surface size. The operation is
completed on the next buffer attach to this surface.
A maximized surface typically fills the entire output it is bound to, except for desktop elements such as
panels. This is the main difference between a maximized shell surface and a fullscreen shell surface.
The details depend on the compositor implementation.

std::function<void(seat_t,uint32_t,surface_t,int32_t,int32_t,shell_surface_transient)>&shell_surface_t::on_set_popup()
make the surface a popup surface
Parametersseat seat whose pointer is used
serial serial number of the implicit grab on the pointer
parent parent surface
x surface-local x coordinate
y surface-local y coordinate
flags transient surface behavior
Map the surface as a popup.
A popup surface is a transient surface with an added pointer grab.
An existing implicit grab will be changed to owner-events mode, and the popup grab will continue after
the implicit grab ends (i.e. releasing the mouse button does not cause the popup to be unmapped).
The popup grab continues until the window is destroyed or a mouse button is pressed in any other client's
window. A click in any of the client's surfaces is reported as normal, however, clicks in other clients'
surfaces will be discarded and trigger the callback.
The x and y arguments specify the location of the upper left corner of the surface relative to the upper
left corner of the parent surface, in surface-local coordinates.

std::function<void(std::string)>&shell_surface_t::on_set_title()
set surface title
Parameterstitle surface title
Set a short title for the surface.
This string may be used to identify the surface in a task bar, window list, or other user interface
elements provided by the compositor.
The string must be encoded in UTF-8.

std::function<void()>&shell_surface_t::on_set_toplevel()
make the surface a toplevel surface Map the surface as a toplevel surface.
A toplevel surface is not fullscreen, maximized or transient.

std::function<void(surface_t,int32_t,int32_t,shell_surface_transient)>&shell_surface_t::on_set_transient()
make the surface a transient surface
Parametersparent parent surface
x surface-local x coordinate
y surface-local y coordinate
flags transient surface behavior
Map the surface relative to an existing surface.
The x and y arguments specify the location of the upper left corner of the surface relative to the upper
left corner of the parent surface, in surface-local coordinates.
The flags argument controls details of the transient behaviour.
