h1. Create a window in Scol

A window is a base of all graphic interface ; it is a container. The Scol type is *ObjWin*.

h2. Creation

To create a window, simple use the Scol function "*_CRwindow*":http://www.scolring.org/files/doc_html/_crwindow.html

<window_object> *_CRwindow* <channel_object> <father_object> <initial_position_x> <initial_position_y> <initial_width> <initial_height> <option_flags> <title>

# <channel_object> : the proprietary channel. If nil, the windown can *not* be created, if the channel os closed, the window will be destroyed. Typically, it is the current channel (__channel_)

# <father_object> : the parent window, if any. If no parent, you should set to nil this argument.

# <initial_position_x>

# <initial_position_y>

# <initial_width>

# <initial_height> : position and size when the window is created

# <option_flags> : several flags are availables to customize the window (see "doc":http://www.scolring.org/files/doc_html/_crwindow.html)

# <title> : a title, if any

You can directly hide a window. In this case, don't forget to show it when needed ("_SHOWwindow":http://www.scolring.org/files/doc_html/_showwindow.html) !

You can also create a window object with scroll : "_CRscrollWindow":http://www.scolring.org/files/doc_html/_crscrollwindow.html

h2. Destruction

To destroy a window object, use "_DSwindow":http://www.scolring.org/files/doc_html/_dswindow.html

<integer> *_DSwindow* <object_window>

If the <object_window> is already destroyed, nothing to do. If the <object_window> is stored in a global variable, you should always set it to nil *after* the destruction of the object.

h2. Example :

<pre>typeof window = ObjWin;;

fun end ()=

    _DSwindow window;

    _closemachine;;

fun create ()=

    set window = _CRwindow _channel nil 0 0 320 240 WN_NORMAL "My first window !";

    _fooS if window == nil then

              "Unable to create this window"

          else

              "The window has been created";

    0;;

fun main ()=

    _showconsole;

    create;

    // other things

    0;;

</pre>
