-
-Destructor, destroying the choice item.

-\constfunc{int}{FindString}{\param{const wxString\& }{string}}
-Finds a choice matching the given string.
+\membersection{wxChoice::Delete}\label{wxchoicedelete}
-\wxheading{Parameters}

+
+Deletes the item with the given index from the control.
-\docparam{string}{String to find.}
+\wxheading{Parameters}
-\wxheading{Return value}
+\docparam{n}{The item to delete.}
-Returns the position if found, or -1 if not found.
\membersection{wxChoice::GetColumns}\label{wxchoicegetcolumns}
\wxheading{Remarks}
-This is implemented for Motif only.
-
-\membersection{wxChoice::GetSelection}\label{wxchoicegetselection}
-
-\constfunc{int}{GetSelection}{\void}
-
-Gets the id (position) of the selected string, or -1 if there is no selection.
-
-\membersection{wxChoice::GetString}\label{wxchoicegetstring}
-
-\constfunc{wxString}{GetString}{\param{const int}{ n}}
+This is implemented for Motif only and always returns $1$ for the other
+platforms.
-Returns the string at the given position.
-\wxheading{Parameters}
-
-\docparam{n}{The zero-based position.}
-
-\wxheading{Return value}
-
-The string at the given position, or the empty string if {\it n} is invalid.

-\membersection{wxChoice::GetStringSelection}\label{wxchoicegetstringselection}
+\constfunc{int}{GetCurrentSelection}{\void}
-\constfunc{wxString}{GetStringSelection}{\void}
+Unlike \helpref{GetSelection}{wxcontrolwithitemsgetselection} which only
+returns the accepted selection value, i.e. the selection in the control once
+the user closes the dropdown list, this function returns the current selection.
+That is, while the dropdown list is shown, it returns the currently selected
+item in it. When it is not shown, its result is the same as for the other
+function.
-Gets the selected string, or the empty string if no string is selected.
+\newsince{2.6.2} (before this version
+\helpref{GetSelection}{wxcontrolwithitemsgetselection} itself behaved like
+this).
-\membersection{wxChoice::Number}\label{wxchoicenumber}
-
-\constfunc{int}{Number}{\void}
-
-Returns the number of strings in the choice control.
\membersection{wxChoice::SetColumns}\label{wxchoicesetcolumns}
-\func{void}{SetColumns}{\param{const int}{ n = 1}}
+\func{void}{SetColumns}{\param{int}{ n = 1}}
Sets the number of columns in this choice item.
\wxheading{Remarks}
-This is implemented for Motif only.
