function [hout,ax_out] = uibutton(varargin)

%uibutton: Create pushbutton with more flexible labeling than uicontrol.

% Usage:

% uibutton accepts all the same arguments as uicontrol except for the

% following property changes:

%

% Property Values

% ----------- ------------------------------------------------------

% Style 'pushbutton', 'togglebutton' or 'text', default =

% 'pushbutton'.

% String Same as for text() including cell array of strings and

% TeX or LaTeX interpretation.

% Interpreter 'tex', 'latex' or 'none', default = default for text()

%

% Syntax:

% handle = uibutton('PropertyName',PropertyValue,...)

% handle = uibutton(parent,'PropertyName',PropertyValue,...)

% [text_obj,axes_handle] = uibutton('Style','text',...

% 'PropertyName',PropertyValue,...)

%

% uibutton creates a temporary axes and text object containing the text to

% be displayed, captures the axes as an image, deletes the axes and then

% displays the image on the uicontrol. The handle to the uicontrol is

% returned. If you pass in a handle to an existing uicontol as the first

% argument then uibutton will use that uicontrol and not create a new one.

%

% If the Style is set to 'text' then the axes object is not deleted and the

% text object handle is returned (as well as the handle to the axes in a

% second output argument).
