What is Event driven programming in VB?
Events are the actions that are performed by the user during the applications usage. If a user clicks a mouse button on any object then the Click event occurs. If a user moves the mouse then the mouse move event occurs. By the same way an application can generate Key down event, Key up event, mouse double click event.
Write a program for event handling mouse and keyboard events?
So far the only event used is the on_draw event. To react to keyboard and mouse events, it's necessary to write and attach event handlers for these events as well: import pyglet window = pyglet.window.Window() @window.event def on_key_press(symbol, modifiers): print 'A key was pressed' @window.event def on_draw(): window.clear() pyglet.app.run() Keyboard events have two parameters: the virtual key symbol that was pressed, and a bitwise combination of any modifiers that are present (for example, the CTRL and SHIFT keys). The key symbols are defined in pyglet.window.key: from pyglet.window import key @window.event def on_key_press(symbol, modifiers): if symbol == key.A: print 'The "A" key was pressed.' elif symbol == key.LEFT: print 'The left arrow key was pressed.' elif symbol == key.ENTER: print 'The enter key was pressed.' See the pyglet.window.key documentation for a complete list of key symbols. Mouse events are handled in a similar way: from pyglet.window import mouse @window.event def on_mouse_press(x, y, button, modifiers): if button == mouse.LEFT: print 'The left mouse button was pressed.' The x and y parameters give the position of the mouse when the button was pressed, relative to the lower-left corner of the window. There are more than 20 event types that you can handle on a window. The easiest way to find the event name and parameters you need is to add the following line to your program: window.push_handlers(pyglet.window.event.WindowEventLogger()) This will cause all events received on the window to be printed to the console.
Active component in resistors and capacitors?
Resistors, capacitors, inductors, diodes are all passive components.
Which component class is also a container in JAVA?
Well, the Container extends Component, so ALL containers in Java are components. This includes classes like Panel, ScrollPane, Window, and JComponent. Plus all the various generations of subclasses of each of those containers.
What is the difference between component and container?
A component is an object, like a button or a scroll bar. It has a visual representation. A container is a window-like component that can contain other components. Every component has a unique container that directly contains it.

What is event handle?
Event HandlingWhen the user acts on a Component -- clicking it or pressing the Return key, for example -- an Event object is created. The AWT event-handling system passes the Event up the Component hierarchy, giving each Component a chance to react to the event before the platform-dependent code that implements the Component fully processes it. Each Component's event handler can react to an event in any of the following ways:By ignoring the event and allowing it to be passed up the Component hierarchy. This is what the default Component implementation does. For example, since the TextField class and its TextComponent superclass implement no event handlers, TextFields get the default Component implementation. So when a TextField receives an Event, it ignores it and allows its container to handle it.By modifying the Event instance before it goes further up the hierarchy. For example, a TextField subclass that displays all letters in uppercase might react to the keypress of a lowercase letter by changing the Event to contain the uppercase version of the letter.By reacting in some other way to the event. For example, a TextField subclass (or a TextField's container) could react to a Return keypress by calling a method that processes the text field's contents.By intercepting the event, stopping it from being processed further. For example, if an invalid character is entered in a text field, an event handler could simply stop the resulting Event from propagating upward. As a result, the platform-dependent implementation of the text field would never see the event.From a Component's view, the AWT event-handling system is more like an event-filtering system. Platform-dependent code generates an event, but Components get a chance to modify, react to, or intercept the event before the platform-dependent code fully processes the event.
How do you solve a compound event?
A compound event is not a riddle, a puzzle, an equation or inequality that can be solved! It is simply an event that has more than one component events.You can find:the conditions required for all components to occur,the time it takes for all components to occur,the consequences of the compound event occurring,the likelihood of all the components occurring.There are other things that you can find. But none of these is solving anything!
Who was the fastest mouse in all Mehico?
Speedy Gonzales is the fastest mouse in all Mehico!
What components of physical fitness does track and field contain?
All 5 component of fitness is involved in all track and field events. however there importance and distribution will be different from one event to the other. For example, event though the 100m sprint and the 400m are both categorized as speed event, absolute speed is more important to the 100m sprinter than it is for the 400m runner.
Is communication a component of risk management?
Communication is a component of all subjects.
Whats event handing in java?
This refers mainly to events that can happen when programming with a graphical user interface; in Java, this might be programmed with the Swing platform. The idea is to react to different "events", things that can happen, often as a result of user interaction. Such events include mouse actions (mouse click, mouse button pressed, mouse button released, mouse enters a visual object, mouse leaves a visual object), keyboard actions (such as pressing a key), focus changes (an object gets or loses the "focus" or "control" - for example, when you press Tab, you change the active control), and timer events (a certain time has passed). "Event handling" simply means being able to detect, and react to, all of these events.
