\subsection{Detailed Description}
Manages the position of an item. 

Every item has at least one public \hyperlink{class_q_c_p_item_position}{Q\+C\+P\+Item\+Position} member pointer which provides ways to position the item on the \hyperlink{class_q_custom_plot}{Q\+Custom\+Plot} surface. Some items have multiple positions, for example \hyperlink{class_q_c_p_item_rect}{Q\+C\+P\+Item\+Rect} has two\+: {\itshape top\+Left} and {\itshape bottom\+Right}.

\hyperlink{class_q_c_p_item_position}{Q\+C\+P\+Item\+Position} has a type (\hyperlink{class_q_c_p_item_position_aad9936c22bf43e3d358552f6e86dbdc8}{Position\+Type}) that can be set with \hyperlink{class_q_c_p_item_position_aa476abf71ed8fa4c537457ebb1a754ad}{set\+Type}. This type defines how coordinates passed to \hyperlink{class_q_c_p_item_position_aa988ba4e87ab684c9021017dcaba945f}{set\+Coords} are to be interpreted, e.\+g. as absolute pixel coordinates, as plot coordinates of certain axes, etc.

Further, \hyperlink{class_q_c_p_item_position}{Q\+C\+P\+Item\+Position} may have a parent \hyperlink{class_q_c_p_item_anchor}{Q\+C\+P\+Item\+Anchor}, see \hyperlink{class_q_c_p_item_position_ac094d67a95d2dceafa0d50b9db3a7e51}{set\+Parent\+Anchor}. (Note that every \hyperlink{class_q_c_p_item_position}{Q\+C\+P\+Item\+Position} inherits from \hyperlink{class_q_c_p_item_anchor}{Q\+C\+P\+Item\+Anchor} and thus can itself be used as parent anchor for other positions.) This way you can tie multiple items together. If the \hyperlink{class_q_c_p_item_position}{Q\+C\+P\+Item\+Position} has a parent, the coordinates set with \hyperlink{class_q_c_p_item_position_aa988ba4e87ab684c9021017dcaba945f}{set\+Coords} are considered to be absolute values in the reference frame of the parent anchor, where (0, 0) means directly ontop of the parent anchor. For example, You could attach the {\itshape start} position of a \hyperlink{class_q_c_p_item_line}{Q\+C\+P\+Item\+Line} to the {\itshape bottom} anchor of a \hyperlink{class_q_c_p_item_text}{Q\+C\+P\+Item\+Text} to make the starting point of the line always be centered under the text label, no matter where the text is moved to, or is itself tied to.

To set the apparent pixel position on the \hyperlink{class_q_custom_plot}{Q\+Custom\+Plot} surface directly, use \hyperlink{class_q_c_p_item_position_ab404e56d9ac2ac2df0382c57933a71ef}{set\+Pixel\+Point}. This works no matter what type this \hyperlink{class_q_c_p_item_position}{Q\+C\+P\+Item\+Position} is or what parent-\/child situation it is in, as \hyperlink{class_q_c_p_item_position_ab404e56d9ac2ac2df0382c57933a71ef}{set\+Pixel\+Point} transforms the coordinates appropriately, to make the position appear at the specified pixel values.

Sets the coordinates of this \hyperlink{class_q_c_p_item_position}{Q\+C\+P\+Item\+Position}. What the coordinates mean, is defined by the type (\hyperlink{class_q_c_p_item_position_aa476abf71ed8fa4c537457ebb1a754ad}{set\+Type}).

For example, if the type is \hyperlink{class_q_c_p_item_position_aad9936c22bf43e3d358552f6e86dbdc8a564f5e53e550ead1ec5fc7fc7d0b73e0}{pt\+Absolute}, {\itshape key} and {\itshape value} mean the x and y pixel position on the \hyperlink{class_q_custom_plot}{Q\+Custom\+Plot} surface. In that case the origin (0, 0) is in the top left corner of the \hyperlink{class_q_custom_plot}{Q\+Custom\+Plot} viewport. If the type is \hyperlink{class_q_c_p_item_position_aad9936c22bf43e3d358552f6e86dbdc8ad5ffb8dc99ad73263f7010c77342294c}{pt\+Plot\+Coords}, {\itshape key} and {\itshape value} mean a point in the plot coordinate system defined by the axes set by \hyperlink{class_q_c_p_item_position_a2185f45c75ac8cb9be89daeaaad50e37}{set\+Axes}. By default those are the \hyperlink{class_q_custom_plot}{Q\+Custom\+Plot}\textquotesingle{}s x\+Axis and y\+Axis. See the documentation of \hyperlink{class_q_c_p_item_position_aa476abf71ed8fa4c537457ebb1a754ad}{set\+Type} for other available coordinate types and their meaning.

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Sets the coordinates as a Q\+Point\+F {\itshape pos} where pos.\+x has the meaning of {\itshape key} and pos.\+y the meaning of {\itshape value} of the \hyperlink{class_q_c_p_item_position_aa988ba4e87ab684c9021017dcaba945f}{set\+Coords(double key, double value)} method. \hypertarget{class_q_c_p_item_position_ac094d67a95d2dceafa0d50b9db3a7e51}{}\index{Q\+C\+P\+Item\+Position@{Q\+C\+P\+Item\+Position}!set\+Parent\+Anchor@{set\+Parent\+Anchor}}

Sets the parent of this \hyperlink{class_q_c_p_item_position}{Q\+C\+P\+Item\+Position} to {\itshape parent\+Anchor}. This means the position will now follow any position changes of the anchor. The local coordinate system of positions with a parent anchor always is absolute with (0, 0) being exactly on top of the parent anchor. (Hence the type shouldn\textquotesingle{}t be \hyperlink{class_q_c_p_item_position_aad9936c22bf43e3d358552f6e86dbdc8ad5ffb8dc99ad73263f7010c77342294c}{pt\+Plot\+Coords} for positions with parent anchors.)

if {\itshape keep\+Pixel\+Position} is true, the current pixel position of the \hyperlink{class_q_c_p_item_position}{Q\+C\+P\+Item\+Position} is preserved during reparenting. If it\textquotesingle{}s set to false, the coordinates are set to (0, 0), i.\+e. the position will be exactly on top of the parent anchor.

To remove this \hyperlink{class_q_c_p_item_position}{Q\+C\+P\+Item\+Position} from any parent anchor, set {\itshape parent\+Anchor} to 0.

If the \hyperlink{class_q_c_p_item_position}{Q\+C\+P\+Item\+Position} previously had no parent and the type is \hyperlink{class_q_c_p_item_position_aad9936c22bf43e3d358552f6e86dbdc8ad5ffb8dc99ad73263f7010c77342294c}{pt\+Plot\+Coords}, the type is set to \hyperlink{class_q_c_p_item_position_aad9936c22bf43e3d358552f6e86dbdc8a564f5e53e550ead1ec5fc7fc7d0b73e0}{pt\+Absolute}, to keep the position in a valid state. \hypertarget{class_q_c_p_item_position_ab404e56d9ac2ac2df0382c57933a71ef}{}\index{Q\+C\+P\+Item\+Position@{Q\+C\+P\+Item\+Position}!set\+Pixel\+Point@{set\+Pixel\+Point}}

Sets the apparent pixel position. This works no matter what type (\hyperlink{class_q_c_p_item_position_aa476abf71ed8fa4c537457ebb1a754ad}{set\+Type}) this \hyperlink{class_q_c_p_item_position}{Q\+C\+P\+Item\+Position} is or what parent-\/child situation it is in, as coordinates are transformed appropriately, to make the position finally appear at the specified pixel values.

Only if the type is \hyperlink{class_q_c_p_item_position_aad9936c22bf43e3d358552f6e86dbdc8a564f5e53e550ead1ec5fc7fc7d0b73e0}{pt\+Absolute} and no parent anchor is set, this function\textquotesingle{}s effect is identical to that of \hyperlink{class_q_c_p_item_position_aa988ba4e87ab684c9021017dcaba945f}{set\+Coords}.

Sets the type of the position. The type defines how the coordinates passed to \hyperlink{class_q_c_p_item_position_aa988ba4e87ab684c9021017dcaba945f}{set\+Coords} should be handled and how the \hyperlink{class_q_c_p_item_position}{Q\+C\+P\+Item\+Position} should behave in the plot.

The possible values for {\itshape type} can be separated in two main categories\+:

\begin{DoxyItemize}
\item The position is regarded as a point in plot coordinates. This corresponds to \hyperlink{class_q_c_p_item_position_aad9936c22bf43e3d358552f6e86dbdc8ad5ffb8dc99ad73263f7010c77342294c}{pt\+Plot\+Coords} and requires two axes that define the plot coordinate system. They can be specified with \hyperlink{class_q_c_p_item_position_a2185f45c75ac8cb9be89daeaaad50e37}{set\+Axes}. By default, the \hyperlink{class_q_custom_plot}{Q\+Custom\+Plot}\textquotesingle{}s x-\/ and y\+Axis are used.\end{DoxyItemize}
\begin{DoxyItemize}
\item The position is fixed on the \hyperlink{class_q_custom_plot}{Q\+Custom\+Plot} surface, i.\+e. independent of axis ranges. This corresponds to all other types, i.\+e. \hyperlink{class_q_c_p_item_position_aad9936c22bf43e3d358552f6e86dbdc8a564f5e53e550ead1ec5fc7fc7d0b73e0}{pt\+Absolute}, \hyperlink{class_q_c_p_item_position_aad9936c22bf43e3d358552f6e86dbdc8ac7d6aa89ceacb39658b0d6da061c789a}{pt\+Viewport\+Ratio} and \hyperlink{class_q_c_p_item_position_aad9936c22bf43e3d358552f6e86dbdc8a01080fd00eaf09fa238ef6b73bbfef75}{pt\+Axis\+Rect\+Ratio}. They differ only in the way the absolute position is described, see the documentation of Position\+Type for details. For \hyperlink{class_q_c_p_item_position_aad9936c22bf43e3d358552f6e86dbdc8a01080fd00eaf09fa238ef6b73bbfef75}{pt\+Axis\+Rect\+Ratio}, note that you can specify the axis rect with \hyperlink{class_q_c_p_item_position_a0cd9b326fb324710169e92e8ca0041c2}{set\+Axis\+Rect}. By default this is set to the main axis rect.\end{DoxyItemize}
Note that the position type \hyperlink{class_q_c_p_item_position_aad9936c22bf43e3d358552f6e86dbdc8ad5ffb8dc99ad73263f7010c77342294c}{pt\+Plot\+Coords} is only available (and sensible) when the position has no parent anchor (\hyperlink{class_q_c_p_item_position_ac094d67a95d2dceafa0d50b9db3a7e51}{set\+Parent\+Anchor}).

If the type is changed, the apparent pixel position on the plot is preserved. This means the coordinates as retrieved with coords() and set with \hyperlink{class_q_c_p_item_position_aa988ba4e87ab684c9021017dcaba945f}{set\+Coords} may change in the process. \hypertarget{class_q_c_p_item_position_a577a7efc601df85a20b3e709d1ac320e}{}\index{Q\+C\+P\+Item\+Position@{Q\+C\+P\+Item\+Position}!to\+Q\+C\+P\+Item\+Position@{to\+Q\+C\+P\+Item\+Position}}

Returns 0 if this instance is merely a \hyperlink{class_q_c_p_item_anchor}{Q\+C\+P\+Item\+Anchor}, and a valid pointer of type Q\+C\+P\+Item\+Position$\ast$ if it actually is a \hyperlink{class_q_c_p_item_position}{Q\+C\+P\+Item\+Position} (which is a subclass of \hyperlink{class_q_c_p_item_anchor}{Q\+C\+P\+Item\+Anchor}).

This safe downcast functionality could also be achieved with a dynamic\+\_\+cast. However, \hyperlink{class_q_custom_plot}{Q\+Custom\+Plot} avoids dynamic\+\_\+cast to work with projects that don\textquotesingle{}t have R\+T\+T\+I support enabled (e.\+g. -\/fno-\/rtti flag with gcc compiler).
