This document provides an overview of Visual Basic 6.0 and how to create a basic application. It outlines the objectives of learning Visual Basic and describes key concepts like the event-driven nature of VB applications. The document explains the structure of a VB project, including forms, controls, properties, methods and events. It also demonstrates how to set control properties, write code, declare variables, and use common functions and operators. Finally, it provides examples for creating a stopwatch timer application and a basic text editor application in VB.
This document discusses the evolution of graphical user interface (GUI) capabilities in the Java programming language. It describes the Abstract Window Toolkit (AWT) introduced in JDK 1.0, which provided basic cross-platform GUI functionality but had limitations. JDK 1.1 improved on AWT with an event delegation model. JDK 1.2 introduced Swing, a richer GUI library that better integrated with native operating system look and feels. Swing components are lightweight compared to heavyweight AWT components. The document also covers GUI component classes, layout managers, menus, labels and event handling in Java GUI programming.
This document provides an overview of event-driven programming and Visual Basic fundamentals. It discusses what an event-driven program is and how it differs from procedural programming by responding to events like button clicks rather than executing code sequentially. It also covers building a first Visual Basic application, including planning the user interface and code, and using intrinsic controls. Additional sections explain properties, methods, and events of objects, and working with Visual Basic projects by opening, saving, and running them.
The document discusses the Controls object in Microsoft Small Basic, which allows adding controls like text boxes and buttons to the graphics window. It describes various operations and properties of the Controls object, such as AddTextBox to add a text box, GetTextBoxText to retrieve text from a text box, and ButtonClicked and TextTyped events. Control events can generate actions when a button is clicked or text is typed in a text box. The document provides an example of a program that uses the Controls object and ends by asking the reader to write a program to display a simple form with text boxes and a submit button.
Throughout the semester, we have been working on command line applic.pdfbirajdar2
Throughout the semester, we have been working on command line applications. While the
command line can be a powerful form of interacting with the computer, most modern
applications have a graphical user interface, or GUI. This program will give you some initial
experience making GUI applications with Swing.
1. Write an original GUI application in Java using Swing. The program can be a simple game, or
an application that demonstrates some of the capabilities of Swing, for example.
2. The application must do something non-trivial that is controlled by GUI components such as
buttons, text boxes, drop-down boxes, etc. For example, it might draw different things, or change
colors, based on button presses.
3. The GUI elements should be layed out reasonably using layout managers.
4. At least one element in your GUI program besides the title bar must include your name.
Suggestions
Get the skeleton of your GUI working first. First get the buttons drawing properly, then go on to
listen to and respond to events.
Initially, hook up the event listeners so that they print something to the console when a button is
pressed. That way you can know that your code is getting events.
If your program will draw shapes, make a subclass of JPanel called \"DrawPanel\" or something
like that to draw the objects and your name. Override the \"paintComponent\" method of this
class.
Solution
import javax.swing.*; import java.awt.*; class gui{ public static void main(String args[]){
//Creating the Frame JFrame frame = new JFrame(\"Chat Frame\");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setSize(400,400);
//Creating the MenuBar and adding components JMenuBar mb = new JMenuBar(); JMenu m1 =
new JMenu(\"FILE\"); JMenu m2 = new JMenu(\"Help\"); mb.add(m1); mb.add(m2);
JMenuItem m11 = new JMenuItem(\"Open\"); JMenuItem m22 =new JMenuItem(\"Save as\");
m1.add(m11); m1.add(m22); //Creating the panel at bottom and adding components JPanel panel
= new JPanel(); // the panel is not visible in output JLabel label = new JLabel(\"Enter Text\");
JTextField tf = new JTextField(10);// accepts upto 10 characters JButton send = new
JButton(\"Send\"); JButton reset = new JButton(\"Reset\"); panel.add(label);// Components
Added using Flow Layout panel.add(tf); panel.add(send); panel.add(reset); // Text Area at the
Center JTextArea ta = new JTextArea(); //Adding Components to the frame.
frame.getContentPane().add(BorderLayout.SOUTH,panel);
frame.getContentPane().add(BorderLayout.NORTH,mb);
frame.getContentPane().add(BorderLayout.CENTER,ta); frame.setVisible(true); } }.
The fundamental problems of GUI applications and why people choose ReactOliver N
Instead of asking people which JavaScript framework to learn, let's look back into GUI application architecture (which Web Front-end is a case). Then you will understand why people created those library & frameworks and why React became so popular.
To create GUIs in MATLAB, one can use the Graphical User Interface Development Environment (GUIDE) tool. GUIDE allows users to drag and drop GUI components like buttons and sliders. It generates code to control the GUI. Key aspects of GUIs include components, figures to contain components, and callback functions that specify what happens when a component is selected. Well-designed GUIs help users know where they are and where to go next within the program.
The document provides an overview of basic WPF controls, including text controls like Label and TextBox, button controls like Button and ToggleButton, list controls like ComboBox and ListView, and other controls like Slider, ProgressBar, ToolTip, and how to create custom UserControls. It includes examples and brief descriptions of each control and discusses properties, events, and how to customize their appearance and behavior.
This document provides an overview of WinForms GUI programming in .NET. It discusses how event-driven programming works in WinForms applications and how Visual Studio supports drag-and-drop design of WinForms. It also describes some key concepts like forms, controls, properties and events.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

3. What is a GUI?
Graphical User Interface
What?
A pictorial based interface that uses menus, buttons,
the mouse, and other “graphics” to communicate with
the user. [No command line interaction]
Examples:
The Windows Calculator
Firefox, Thunderbird, Office
Anything you are looking at [on the computer].
4. What is a GUI in MATLAB?
GUI’s in MATLAB consist of two files:
An “m-file” [******.m]
A “fig-file” [******.fig]
The m-file has all of the code that controls the
GUI
The fig-file has all of the graphical objects,
positions, default values, and links it all together
5. MATLAB GUI -- Example
Edit Text
Boxes
Radio
Button
Push Button
Axes
Panel
Static Text
Pop Up-menu
6. MATLAB GUI -- Example
Sliders
to Change figure.
This is the “Superquadrics”
demo included with MATLAB.
7. Handle Graphics
Handle graphics are low-level graphic
functions that control characteristics generated
by MATLAB. They allow the programmer to
have precise control of the appearance of plots
and graphics.1
Examples: turning the grid on or off, changing
colors or line types of plotted data, changing the
marker type or line width.

8. Handle Graphics
Each component has a list of properties that
define what it looks like and how it behaves.
Plot Something:
Figure Window View Property Editor
More Properties
10. Handle Graphics
The manipulation of these properties form the
basis of GUIs and GUI programming in
MATLAB.
The ‘handle’
>> fh = figure();
>> set(fh,'Name','Figure: Meet the World!');
>> set(fh,'NumberTitle','off');
>> ph = plot([1:10],[1:10].^2);
>> set(ph,'LineStyle','--');
>> set(ph,'Marker','square');
>> set(ph,'MarkerEdgeColor',[1 0 0],
'MarkerFaceColor',[0 1 0]);
>> get(ph); get(fh); %Look at all properties
11. Handle Graphics
The ‘set’ and ‘get’ commands
These are the primary commands that you use to
… set and get information about graphic objects,
they update the graphical object immediately
Syntax: ‘set’
>> set(object_hndl,'PropertyName',propvalue);
Syntax: ‘get’
>> propvalue = get(object_hndl,'PropertyName');
12. Creating a GUI
Step 1: Create the graphical components
Using the GUIDE
Manually configure each component
Step 2: Program components

Section Description
Comments Displayed at the command line in response to the help
command. Edit these as necessary for your GUI.
Initialization GUIDE initialization tasks. Do not edit this code.
Opening
function
Performs your initialization tasks before the user has access
to the GUI.
Output
function
Returns outputs to the MATLAB command line after the
opening function returns control and before control returns to
the command line.
Component
and figure
callbacks
Control the behavior of the GUI figure and of individual
components. MATLAB calls a callback in response to a
particular event for a component or for the figure itself.
22. Step 2: Programming the GUI
Callbacks: An Overview
What is a Callback
A function associated with a GUI component. It
controls the behavior by performing an action in
response to an event.
Kinds of Callbacks
Table
23. Step 2: Programming the GUI
Callback Syntax and Arguments
Most callbacks will look similar to this:
% --- Executes on button press in pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton1 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
...
Insert your code after the last comment
Read the comments, they might help you
24. Step 2: Programming the GUI
Naming of Callbacks
function pushbutton1_Callback(hObject, eventdata, handles)
name
Input Arguments
hObject Handle of the object, e.g., the component
eventdata Reserved for later use.
handles Structure that contains the handles of all the objects in the
figure. It may also contain application-defined data.
25. Step 2: Programming the GUI
Adding Callbacks
The GUIDE only creates the most common
callbacks
You may want to create different ones:
Right-click on the component you want
You are now looking at the Layout Editor context menu*
Select View callbacks
Select the callback you wish to create
The GUIDE will now add it to the m-file and open it.
26. Step 2: Programming the GUI
There are two key functions:
set
sets values
get
gets current values
27. Step 2: Programming the GUI
the get function
We have seen many examples:
user_data = get(hObject,’String’);
returns string in hObject
user_data = get(hObject,’Value’);
returns value in hObject
user_data = get(hObject,’max’);
returns max possible value in hObject*
same for min
Please note:
These commands only work when you are inside the callback
function you are trying to “get” the value of.
28. Step 2: Programming the GUI
the get function
In general:
To access data stored in a component somewhere else in your
program:
user_data = get(handles.component_name,’Value’)
Where “component_name” is a component which has a property
called ‘Value’
component_name is generally structured like this:
[component type] [number] i.e. edit1 - pushbutton3 - edit2
You may change this [But be careful, read the help files]
29. Step 2: Programming the GUI
the set function
In general:
To set [output] values or strings to components in your GUI:
set(handles.component_name,’propertyname’,valuetoset)
Where “component_name” is a component which has a property
called ‘Value’
You can set any property like this
30. Step 2: Programming the GUI
Important:
You can and most likely will use the following in
conjunction with one another:
set get
num2str str2double
Example:
set(handles.edittext1,'String',…
num2str(get(handles.slider1,'Value')));
This will set the “String” for edittext1 as the “Value” of slider1.
The num2str is used because the “String” must be a string and the
“Value” is stored as a number so, num2str converts it accordingly.

Components
Push Button
Push Button
This example contains only a push button.
Clicking the button, closes the GUI.
This is the push button's Callback. It displays the string Goodbye at the
command line and then closes the GUI.
function pushbutton1_Callback(hObject, eventdata, handles)
disp(‘Goodbye’)
delete(handles.figure1);
33. Programming the GUI
Components
Toggle Button
The callback for a toggle button needs to query the toggle button to
determine what state it is in. MATLAB sets the Value property equal to
the Max property when the toggle button is pressed (Max is 1 by default)
and equal to the Min property when the toggle button is not pressed
(Min is 0 by default).
The following code illustrates how to program the callback in the GUI M-
file.
function togglebutton1_Callback(hObject, eventdata, handles)
button_state = get(hObject,'Value');
if button_state == get(hObject,'Max')
% Toggle button is pressed-take approperiate action
% ...
elseif button_state == get(hObject,'Min')
% Toggle button is not pressed-take appropriate action
...
end
34. Programming the GUI
Components
Radio Button
You can determine the current state of a radio button from within its
callback by querying the state of its Value property, as illustrated in the
following example:
if (get(hObject,'Value') == get(hObject,'Max'))
% Radio button is selected-take appropriate action
else
% Radio button is not selected-take appropriate action
end
Note: You can use a button group to mange exclusive
selection behavior for radio buttons and toggle buttons.
35. Programming the GUI
Components
Check Box
You can determine the current state of a check box from within its
callback by querying the state of its Value property, as illustrated in the
following example:
function checkbox1_Callback(hObject, eventdata, handles)
if (get(hObject,'Value') == get(hObject,'Max'))
% Checkbox is checked-take approriate action
else
% Checkbox is not checked-take approriate action
end
36. Programming the GUI
Components
Edit Text
To obtain the string a user types in an edit box, get the
String property in the the Callback.
function edittext1_Callback(hObject, eventdata, handles)
user_string = get(hObject,'String');
% Proceed with callback
Retrieving Numeric Data from an Edit Text
Component
MATLAB returns the value of the edit text String property as a
character string. If you want users to enter numeric values,
you must convert the characters to numbers. You can do this
using the str2double command, which converts strings to
doubles. If the user enters nonnumeric characters, str2double
returns NaN.
37. Programming the GUI
Components
Edit Text (cont.)
You can use the following code in the edit text callback. It gets
the value of the String property and converts it to a double. It
then checks whether the converted value is NaN (isnan),
indicating the user entered a nonnumeric character and displays
an error dialog (errordlg).
function edittext1_Callback(hObject, eventdata, handles)
user_entry = str2double(get(hObject,'string'));
if isnan(user_entry)
errordlg('You must enter a numeric value', ...
'Bad Input','modal')
return
end
% Proceed with callback...
38. Programming the GUI
Components
Slider
You can determine the current value of a slider from
within its callback by querying its Value property, as
illustrated in the following example:
function slider1_Callback(hObject, eventdata, handles)
slider_value = get(hObject,'Value');
% Proceed with callback...
The Max and Min properties specify the slider's
maximum and minimum values. The slider's range is
Max - Min.
39. Programming the GUI
Components
List Box
When the list box Callback is triggered, the list box Value property
contains the index of the selected item, where 1 corresponds to the first
item in the list. The String property contains the list as a cell array of
strings.
This example retrieves the selected string. It assumes listbox1 is the
value of the Tag property. Note that it is necessary to convert the value
returned from the String property from a cell array to a string.
function listbox1_Callback(hObject, eventdata, handles)
index_selected = get(hObject,'Value');
list = get(hObject,'String');
item_selected = list{index_selected};
% Convert from cell array to string
40. Programming the GUI
Components
Pop-Up Menu
When the pop-up menu Callback is triggered, the pop-up menu Value
property contains the index of the selected item, where 1 corresponds to
the first item on the menu. The String property contains the menu items
as a cell array of strings.
Using Only the Index of the Selected Menu Item
This example retrieves only the index of the item selected. It uses a
switch statement to take action based on the value. If the contents of the
pop-up menu are fixed, then you can use this approach. Else, you can
use the index to retrieve the actual string for the selected item.
function popupmenu1_Callback(hObject, eventdata, handles)
val = get(hObject,'Value');
switch val
case 1
% User selected the first item
case 2
% User selected the second item
end
% Proceed with callback...
41. Programming the GUI
Components
Panel
Panels group GUI components and can make a GUI easier to
understand by visually grouping related controls. A panel can contain
panels and button groups as well as axes and user interface controls
such as push buttons, sliders, pop-up menus, etc. The position of each
component within a panel is interpreted relative to the lower-left corner
of the panel.
Generally, if the GUI is resized, the panel and its components are also
resized. However, you can control the size and position of the panel and
its components. You can do this by setting the GUI Resize behavior to
Other (Use ResizeFcn) and providing a ResizeFcn callback for the
panel.
Note: To set Resize behavior for the figure to Other (Use ResizeFcn),
select GUI Options from the Layout Editor Tools menu.
42. Programming the GUI
Components
Button Group
Button groups are like panels except that they manage exclusive
selection behavior for radio buttons and toggle buttons. If a button group
contains a set of radio buttons, toggle buttons, or both, the button group
allows only one of them to be selected. When a user clicks a button, that
button is selected and all others are deselected.
The following figure shows a button group with two radio buttons and two
toggle buttons. Radio Button 1 is selected.
43. Programming the GUI
Components
Button Group (cont.)
If a user clicks the other radio button or one of the toggle buttons, it becomes
selected and Radio Button 1 is deselected. The following figure shows the
result of clicking Toggle Button 2.
The button group's SelectionChangeFcn callback is called whenever a
selection is made. Its hObject input argument contains the handle of the
selected radio button or toggle button.
44. Programming the GUI
Components
Button Group (cont.)
If you have a button group that contains a set of radio buttons
and toggle buttons and you want:
An immediate action to occur when a radio button or toggle button is selected,
you must include the code to control the radio and toggle buttons in the button
group's SelectionChangeFcn callback function, not in the individual toggle
button Callback functions. Color Palette provides a practical example of a
SelectionChangeFcn callback.
Another component such as a push button to base its action on the selection,
then that component's Callback callback can get the handle of the selected
radio button or toggle button from the button group's SelectedObject property.
This example of a SelectionChangeFcn callback uses the Tag
property of the selected object to choose the appropriate code to
execute. Unlike other callbacks, the hObject argument of the
SelectionChangeFcn callback contains the handle of the
selected radio button or toggle button.
45. Programming the GUI
Components
Button Group (cont.)
Example:
function uibuttongroup1_SelectionChangeFcn(hObject,eventdata,handles)
switch get(hObject,'Tag') % Get Tag of selected object
case 'radiobutton1'
% Code for when radiobutton1 is selected.
case 'radiobutton2'
% Code for when radiobutton2 is selected.
case 'togglebutton1'
% Code for when togglebutton1 is selected.
case 'togglebutton2'
% Code for when togglebutton2 is selected.
% Continue with more cases as necessary.
otherwise
% Code for when there is no match.
end
48. Programming for the GUI
Tips:
Set the initial values for everything
Deal with invalid inputs (many different ways to do
this)
Run most of your code from a pushbutton, rather than
small steps as soon as they enter some data. [Unless
carefully designed, then the opposite may work better]
Use the property inspector!
Be creative!
Explore!
