This code places three Elementary Datetime widgets on a window, each of them exemplifying the widget\textquotesingle{}s different usage.

The first of them is {\bfseries{\char`\"{}only Date display\char`\"{}}}\+:

 The third one will display datetime shows both {\bfseries{Date and Time}}, corresponding format will be taken from system {\bfseries{locale}}. Note, besides, that the strings are different for different language settings.

{\bfseries{Datetime format}} can be programmatically set by using \mbox{\hyperlink{group__Elm__Datetime_ga75def6ec9fd0ee435c809ddf187c9bac}{elm\+\_\+datetime\+\_\+format\+\_\+set()}}\+:  
\begin{DoxyCodeInclude}{0}
\DoxyCodeLine{   \textcolor{comment}{//datetime showing both DATE and TIME}}
\DoxyCodeLine{   datetime = \mbox{\hyperlink{group__Elm__Datetime_ga3dac2d32e2137fac111d91dc15fcc270}{elm\_datetime\_add}}(bx);}
\DoxyCodeLine{   \mbox{\hyperlink{group__Evas__Object__Group_ga2af897b00f32bebf08705929276386f5}{evas\_object\_size\_hint\_weight\_set}}(datetime, \mbox{\hyperlink{Evas__Common_8h_aa47c85083d3dae0111c21ec49359306a}{EVAS\_HINT\_EXPAND}}, \mbox{\hyperlink{Evas__Common_8h_aa47c85083d3dae0111c21ec49359306a}{EVAS\_HINT\_EXPAND}});}

The default format of any locale consists\+:
\begin{DoxyItemize}
\item Year Field
\item Month Field
\item Date Field
\item Hour Field(12hr/24hr format)
\item Minute Field
\item AM/\+PM (if exists).
\end{DoxyItemize}

This is how the example program\textquotesingle{}s window looks like with the datetime widget showing only date, only time and both date \& time\+:

 
\begin{DoxyImageNoCaption}
  \mbox{\includegraphics[width=\textwidth]{screenshots/datetime_example}}
