  54. \subsection{Detailed Description}
  55. The abstract base class for layouts.
  56. This is an abstract base class for layout elements whose main purpose is to define the position and size of other child layout elements. In most cases, layouts don\textquotesingle{}t draw anything themselves (but there are exceptions to this, e.\+g. \hyperlink{class_q_c_p_legend}{Q\+C\+P\+Legend}).
  57. \hyperlink{class_q_c_p_layout}{Q\+C\+P\+Layout} derives from \hyperlink{class_q_c_p_layout_element}{Q\+C\+P\+Layout\+Element}, and thus can itself be nested in other layouts.
  58. \hyperlink{class_q_c_p_layout}{Q\+C\+P\+Layout} introduces a common interface for accessing and manipulating the child elements. Those functions are most notably \hyperlink{class_q_c_p_layout_a39d3e9ef5d9b82ab1885ba1cb9597e56}{element\+Count}, \hyperlink{class_q_c_p_layout_afa73ca7d859f8a3ee5c73c9b353d2a56}{element\+At}, \hyperlink{class_q_c_p_layout_a5a79621fa0a6eabb8b520cfc04fb601a}{take\+At}, \hyperlink{class_q_c_p_layout_ada26cd17e56472b0b4d7fbbc96873e4c}{take}, \hyperlink{class_q_c_p_layout_a41e6ac049143866e8f8b4964efab01b2}{simplify}, \hyperlink{class_q_c_p_layout_a2403f684fee3ce47132faaeed00bb066}{remove\+At}, \hyperlink{class_q_c_p_layout_a6c58f537d8086f352576ab7c5b15d0bc}{remove} and \hyperlink{class_q_c_p_layout_a02883bdf2769b5b227f0232dba1ac4ee}{clear}. Individual subclasses may add more functions to this interface which are more specialized to the form of the layout. For example, \hyperlink{class_q_c_p_layout_grid}{Q\+C\+P\+Layout\+Grid} adds functions that take row and column indices to access cells of the layout grid more conveniently.
  59. Since this is an abstract base class, you can\textquotesingle{}t instantiate it directly. Rather use one of its subclasses like \hyperlink{class_q_c_p_layout_grid}{Q\+C\+P\+Layout\+Grid} or \hyperlink{class_q_c_p_layout_inset}{Q\+C\+P\+Layout\+Inset}.
  60. For a general introduction to the layout system, see the dedicated documentation page \hyperlink{thelayoutsystem}{The Layout System}.

If the parent of this layout is again a \hyperlink{class_q_c_p_layout}{Q\+C\+P\+Layout}, forwards the call to the parent\textquotesingle{}s \hyperlink{class_q_c_p_layout_a6218cd7e5c0e30077c1aeaffe55b6145}{size\+Constraints\+Changed}.

  168. If the {\itshape element} isn\textquotesingle{}t in this layout, returns false.
  169. Note that some layouts don\textquotesingle{}t remove the respective cell right away but leave an empty cell after successful removal of the layout element. To collapse empty cells, use \hyperlink{class_q_c_p_layout_a41e6ac049143866e8f8b4964efab01b2}{simplify}.

  196. Then calls update\+Layout which subclasses reimplement to reposition and resize their cells.
