class Window

A window that can accommodate one or more plots to be shown on the screen.

Window()

Create an empty window with a single slot.

Window(const char *layout)

Create an empty window subdivided accordingly to the layout string.

The format string describe the layout of plots inside the window using the following grammar:

layout = element | h | v ;
h = "h" { layout } ;
v = "v" { layout } ;
element = "." | "(" layout ")" ;

The character . means a slot to accommodate a single plot. The letters h and v indicate respectively an horizontal and a vertical split and are followed by one or more sub-layouts. The parenthesis are used fro grouping.

For example to accommodate two plots horizontally use the layout string h... To subdivide a window in a 2x2 grid it can be used the layout string h(v..)(v..).

void SetLayout(const char *layout)

Set the window’s layout using the format string layout like when using the constructor Window::Window(). Can be used only if the windows is not yet running. If the window is already running the call has no effect.

int Attach(Plot &plot, const char *slot)

Attach the given plot inside a window using slot to address the slot. Return an integer index that can be used for the Window::SlotRefresh() function.

The slot string should be composed by integer indexes separated by commas. Each index is used to address a position inside an horizontal or vertical split. Further indexes are used to address a sub-layout, if any is present.

For example for a window layout specified by h.. the simple strings 1 or 2 will address respectively the first and the second slot. For a layout with nested subdivisions, for example, h(v..)(v..) the string 1,2 will address the slot in the first column and the second row.

void SlotRefresh(unsigned index)

Incrementally update the image of the window for the plot in the slot identified by index. Only the elements on the plot marked as pending will be drawn.

void Start(unsigned width, unsigned height, unsigned flags)

Show the window on the screen with the given width and height. Thhe flags currently accept only the WindowResize.

void Wait()

Blocks waiting until the window is closed.
