+<p>wxWidgets was developed to provide a cheap and flexible way to
maximize investment in GUI application development. While a number of
commercial class libraries already existed for cross-platform
development, none met all of the following criteria:</p>

over free libraries without an independent development team), plus a
robustness against the transience of one individual or company. This
openness and availability of source code is especially important when
overstated, since GUI application development is very time-consuming,
and sustained popularity of particular GUIs cannot be guaranteed.

every application (such as an OLE-intensive program), it provides
access to most of the functionality a GUI program normally requires,
plus many extras such as network programming, PostScript output, and
HTML rendering; and it can of course be extended as needs dictate. As
a bonus, it provides a far cleaner and easier programming interface
than the native APIs. Programmers may find it worthwhile to use

<p>The layout algorithm used by sizers in wxPython is closely related to
layout systems in other GUI toolkits, such as Java's AWT, the GTK

<p>All sizers are containers, that is, they are used to lay out one
dialog item (or several dialog items), which they contain. Such items

item, the dialog item can be made to fill out the available space

<p>As mentioned above, any window belonging to a sizer may have border,

using the wx.TOP, wx.LEFT, wx.RIGHT and wx.BOTTOM constants or wx.ALL
for all directions (and you may also use wx.NORTH, wx.WEST etc
instead). These flags can be used in combination with the alignment
flags above as the second parameter of the Add() method using the

controlled by the three parameters of the Add() method.</p>

<p>While there is only one logical way to represent an absolute moment in
the time (and hence only one DateTime class), there are at least two
methods to describe a time interval.</p>

<p>Many different operations may be performed with the dates, however not
all of them make sense. For example, multiplying a date by a number
is an invalid operation, even though multiplying either of the time
span classes by a number is perfectly valid.</p>

<p>Although the time is always stored internally in GMT, you will usually
