void sendClose ()

Sends a close event to the client. The client may choose to ignore the event.

int sendConfigure ( size size , list < int > states )

Sends a configure event to the client. size contains the pixel size of the surface. A size of zero means the client is free to decide the size. Known states are enumerated in XdgToplevel::State.

void sendFullscreen ( size size )

Convenience for sending a configure event with the fullscreen state set, and maximized and resizing removed. The activated state is left in its current state.

size is the new size of the window.

void sendMaximized ( size size )

Convenience for sending a configure event with the maximized state set, and fullscreen and resizing removed. The activated state is left in its current state.

size is the new size of the window.

void sendResizing ( size maxSize )

Convenience for sending a configure event with the resizing state set, and maximized and fullscreen removed. The activated state is left in its current state.

maxSize is the new size of the window.

void sendUnmaximized ( size size )

Convenience for sending a configure event with the maximized, fullscreen and resizing states removed, and fullscreen and resizing removed. The activated state is left in its current state.

size is the new size of the window. If size is zero, the client decides the size.

size sizeForResize ( size size , point delta , uint edges )

Convenience for computing the new size given the current size ， delta ，和 edges active in the drag.
