%% Syntax Considerations for reading the M-Code:
%
% All of the handles to the various objects created in each GUI, as well as
% data needed to run the GUI, are stored in a main structure called S.
% The fieldnames for handles are in lowercase letters, and the fieldnames
% for data are in uppercase letters. Callback function names are
% designated with the fieldname of the object to which they correspond,
% followed by '_call.' Other function names are similarly designated. For
% instance, a keypressfcn will end in '_kpfcn' and a buttondownfcn will end
% in '_bdfcn.' The code of each GUI is generously commented, and subtle
% points may be examined in the comments (see for example the last comment
% block in GUI_37). If anything seems unclear, look first in the comments,
% and if satisfaction is not found there feel free to email me.
%
% THE CODE IN THESE FILES IS MEANT TO BE READ, NOT JUST USED!
%
% Therefore, if there is a need for more elaboration in the comments
% somewhere, please let me know.
%
% Simple summaries of the GUIs are given below. See the help for
% each individual GUI for more details. Also see the accompanying pdf file
% for more general comments.

%% GUI_1 Explore simple string manipulation.
% Pushing the pushbutton deletes the string elements of a listbox one at a
% time.
%
%% GUI_2 Explore simple string manipulation.
% Pushing the pushbutton adds to the string elements of a listbox. The
% added string can be chosen by the user through an editbox.
%
%% GUI_3 Explore visibility properties.
% A uicontrol element is set to be visible and invisible by a checkbox.
%
%% GUI_4 Explore simple string manipulation.
% A multi-line editbox is created, and its string is added to a listbox by
% a pushbutton.
%
%% GUI_5 Explore simple string manipulation and user notification.
% A pushbutton deletes the text in a textbox one character at a time.
% When the string is empty, the user is notified of this fact.
%
%% GUI_6 Explore selection determination.
% Pushing the pushbutton reveals which, if any, of the radiobuttons is
% currently selected.
%
%% GUI_7 Explore selection determination and counting.
% Selecting an item from the popup causes the textbox to display the number
% of times the item has been selected.
%
%% GUI_8 Explore selection determination for a buttongroup.
% Pushing the pushbutton updates an editbox to display which radiobutton in
% the uibuttongroup is selected.
%
%% GUI_9 Explore user notification.
% Pushing the pushbutton causes the GUI to simulate a running process and
% let the user know this process has not finished.
%
%% GUI_10 Explore making an image visible and invisible.
% Just setting the axes visible/invisible is not enough!
%
%% GUI_11 Explore GUI use to stop a FOR loop.
% Pushing the pushbutton causes the FOR loop to stop. Two different uses
% of GUIs are explored through the use of two FOR loops which the user must
% activate.
%
%% GUI_12 Explore mouse pointer manipulation.
% Pushing the pushbutton to close the GUI proves to be very difficult.
%
%% GUI_13 Explore slider and editbox interaction.
% An editbox is used to display and manipulate the current position of a
% slider.
%
%% GUI_14 Explore string color control.
% A listbox with strings of different colors is presented. Pushing the
% pushbutton prints the user's choice to the command window.
%
%% GUI_15 Explore simple string manipulation.
% An editbox is presented which has text that the user can copy, but not
% change.
%
%% GUI_16 Explore slider and editbox interaction.
% Three editboxes are used to display and manipulate the current position,
% minimum and maximum of a slider.
%
%% GUI_17 Explore clock and timer use in a GUI.
% A single textbox is used to display a running clock.
%
%% GUI_18 Explore the buttondownfcn for an axes.
% Clicking in the axes creates a random line. Right-clicking deletes that
% line.
%
%% GUI_19 Explore counting and argument detection.
% Pushing either of the pushbuttons causes the total number of pushes and
% the number of arguments passed to one of their callbacks to display.
%
%% GUI_20 Explore popup selection determination.
% Choosing an item from the popup causes the editbox to display the choice.
%
%% GUI_21 Explore popup selection determination and manipulation.
% Similar to GUI_20, except that the editbox is allowed to select a value
% from the popup.
%
%% GUI_22 Explore popup selection determination and manipulation.
% Similar to GUI_21, except that the editbox is allowed to select a value
% from the popup. The editbox may also add an item to the popup.
%
%% GUI_23 Explore multiple-figure data-passing, and the stacking order.
% An editbox is made which will add a title to a selected figure/axes.
%
%% GUI_24 Explore multiple-figure data-passing.
% Pushing the pushbutton creates another GUI with only a single editbox.
% Any string entered into the new editbox is placed into the first GUI.
%
%% GUI_25 Explore file selection/manipulation.
% A GUI is made which will list all of the .jpg files in the current
% directory. When a file is selected, the data is loaded into the base
% workspace.
%
%% GUI_26 Explore listbox choice restriction.
% Three listboxes are created with the same lists. The user is not allowed
% to have any two listboxes show the same choice.
%
%% GUI_27 Explore pointer location detection and display.
% An axes is created and the current location of the mouse pointer in axes
% coordinates is displayed as a title.
%
%% GUI_28 Explore contextmenues and buttondownfcn.
% An axes is created and clicking in the axes plots a point. Options are
% available by right-clicking on the axes.
%
%% GUI_29 Explore multiple figure interaction.
% A slider is created which controls the xlim of a plot. Closing one
% figure closes them both.
%
%% GUI_30 Explore callback strings.
% Same as GUI_29, only the task of controlling the xlim is accomplished
% through callback strings.
%
%% GUI_31 Explore multiple interactions among uicontrols.
% A simple calculator is created which features several interactions
% occurring among uicontrols.
%
%% GUI_32 Explore exporting data to the base workspace.
% Same as GUI_31, except the GUI can be called with a string argument.
% This string argument will be the name of a variable created in the base
% workspace when the GUI is closed.
%
%% GUI_33 Explore exporting data to the base workspace.
% Same as GUI_31, except a variable will be created in the base workspace
% through a contextmenu.
%
%% GUI_34 Explore image capturing with a printscreen GUI.
% A GUI is created which captures an image of the users desktop.
%

% A GUI is created which returns a string to whatever function called it,
% or the base workspace.
%
%% GUI_37 Explore string manipulation and nested functions.
% An editbox is created which hides the users strings as asterisks. True
% or false values are returned depending on if the user enters the correct
% password or not.
%
%% GUI_38 Explore the user of JAVA and focussing issues.
% A simple GUI is created which has a pushbutton. Normally the pushbutton
% would retain focus after it has been pushed. This would the require the
% user to click on the figure in order that the figure's keypressfcn should
% be accessable. The figure is given focus after the button press with the
% help of JAVA.
%
%% GUI_39 Explore a simple drawing program and image saving.
% A blank palette is created which allows the user to draw whatever is
% desired. Right-clicking provides color options. The ability to save the
% drawing in an image format is provided.
