openness and availability of source code is especially important when

a bonus, it provides a far cleaner and easier programming interface

<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
toolkit or the Qt toolkit. It is based upon the idea of individual

<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
are sometimes referred to as the children of the sizer. Independent
of how the individual sizers lay out their children, all children have
certain features in common:</p>

<p>StaticBoxSizer is a sizer derived from BoxSizer but adds a static box
around the sizer. Note that this static box has to be created
separately.</p>

<p>As a convenience, the Dialog class has a CreateButtonSizer(flags)

standard buttons are displayed. The following flags can be passed to
this method:</p>

<p>wxPython provides a set of powerful classes to work with dates and
times. Some of the supported features of the DateTime class are:</p>
-<table border class="table">

<col width="18%" />

<p>There are 3 main classes: except DateTime itself which represents an
absolute moment in time, there are also two classes - TimeSpan and
DateSpan which represent the intervals of time.</p>

<p>DateTime stores the time as a signed number of milliseconds since the
Epoch which is fixed, by convention, to Jan 1, 1970 - however this is
not visible to the class users (in particular, dates prior to the

<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>
in situations when you do need to understand what 'in a month' means
(of course, it is just DateTime.Now() + DateSpan.Month()).</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>Here is what can be done:</p>

+<h2><a class="toc-backref" href="#id38" id="time-zone-considerations" name="time-zone-considerations">Time zone considerations</a></h2>
<p>Although the time is always stored internally in GMT, you will usually
work in the local time zone. Because of this, all DateTime
constructors and setters which take the broken down date assume that
printf("The time is %s in local time zone", dt.FormatTime().c_str());
printf("The time is %s in GMT", dt.FormatTime(wxDateTime::GMT).c_str());</p>

<p>DST (a.k.a. 'summer time') handling is always a delicate task which is
better left to the operating system which is supposed to be configured
by the administrator to behave correctly. Unfortunately, when doing
<p>The time zone handling methods use these functions too, so they are
subject to the same limitations.</p>
