Uploading file with Progress Bar. HTML5 introduced the progress bar element, which allows us to show the progress of certain tasks, like uploads or downloads, basically anything that is in progress Since this is a native progress bar, the. Ctongfei / progressbar. A simple console progress bar. This may be useful when the program // gets new information about the current progress. Describes how to display a progress bar with a user form in Excel. You are currently offline, waiting for your internet to reconnect. How to Use Progress Bars (The Java. A user- friendly program provides some indication to the user that the task is occurring, how long the task might take, and how much work has already been done. One way of indicating work, and perhaps the amount of progress, is to use an animated image. Another way of indicating work is to set the wait cursor, using the. Cursor class and the Component- defined. Cursor method. For example, the following code makes the wait cursor be displayed when the cursor is over container (including any components it contains that have no cursor specified). Cursor(Cursor. get. Predefined. Cursor(Cursor. WAIT. You can show work without measurable progress by putting the progress bar in indeterminate mode. A progress bar in indeterminate mode displays animation to indicate that work is occurring. As soon as the progress bar can display more meaningful information, you should switch it back into its default, determinate mode. In the Java look and feel, indeterminate progress bars look like this: Swing provides three classes to help you use progress bars: JProgress. Bar. A visible component to graphically display how much of a total task has completed. See Using Determinate Progress Bars for information and an example of using a typical progress bar. The section Using Indeterminate Mode tells you how to animate a progress bar to show activity before the task's scope is known. Progress. Monitor. Not a visible component. Instead, an instance of this class monitors the progress of a task and pops up a dialog if necessary. See How to Use Progress Monitors for details and an example of using a progress monitor. Progress. Monitor. Input. Stream. An input stream with an attached progress monitor, which monitors reading from the stream. You use an instance of this stream like any of the other input streams described in. Basic I/O. You can get the stream's progress monitor with a call to get. Progress. Monitor and configure it as described in How to Use Progress Monitors. After you see a progress bar and a progress monitor in action, Deciding Whether to Use a Progress Bar or a Progress Monitor can help you figure out which is appropriate for your application. Here's a picture of a small demo application that uses a progress bar to measure the progress of a task that runs in its own thread: The following code, from. Progress. Bar. Demo. Where member variables are declared. JProgress. Bar progress. Bar. .. You can also set these values with set. Minimum and set. Maximum. The minimum and maximum values used in this program are 0 and the length of the task, which is typical of many programs and tasks. However, a progress bar's minimum and maximum values can be any value, even negative. The code snippet also sets the progress bar's current value to 0. By default, the progress bar displays the value returned by its get. Percent. Complete method formatted as a percent, such as 3. Alternatively, you can replace the default with a different string by calling set. String. For example. Bar. set. String(. The Task instance does three important things for Progress. Bar. Demo: The instance invokes the do. In. Background in a separate thread. This is where the long- running task is actually executed. Using a background thread instead of the event- dispatching thread prevents the user interface from freezing while the task is running. When the background task is complete, the instance invokes the done method in the event- dispatching thread. The instance maintains a bound property, progress, that is updated to indicate the progress of the task. The property. Change method is invoked each time progress changes. See. Worker Threads and Swing. Worker in. Concurrency in Swing for more information about Swing. Worker. The background task in Progress. Bar. Demo simulates a real task by reporting random amounts of progress at random intervals. The property. Change method responds to changes in the the task's progress property by updating the progress bar. Change(Property. Change. Event evt) . This is necessary because the final updates to the progress property may occcur after done is invoked. In Progress. Bar. Demo. 2 indeterminate mode is set until actual progress begins. Change(Property. Change. Event evt) . A progress bar that displays a string is likely to be taller than one that doesn't, and, as the demo designers, we've arbitarily decided that this progress bar should display a string only when it's in the default, determinate mode. However, we want to avoid the layout ugliness that might result if the progress bar changed height when it changed modes. Thus, the code leaves in the call to set. String. Painted(true) but adds a call to set. String(. Later, when the progress bar switches from indeterminate to determinate mode, invoking set. String(null) makes the progress bar display its default string. One change we did not make was removing the call to progress. Bar. set. Value from the progress event handler. The call doesn't do any harm because an indeterminate progress bar doesn't use its value property, except perhaps to display it in the status string. In fact, keeping the progress bar's data as up- to- date as possible is a good practice, since some look and feels might not support indeterminate mode. Now let's rewrite Progress. Bar. Demo to use a progress monitor instead of a progress bar. Here's a picture of the new demo program, Progress. Monitor. Demo: A progress monitor cannot be used again, so a new one must be created each time a new task is started. This program creates a progress monitor each time the user starts a new task with the Start button. Here's the statement that creates the progress monitor. Monitor = new Progress. Monitor(Progress. Monitor. Demo. this. This string is displayed on the dialog. The example uses an empty string to indicate that the dialog should make space for a changeable status note, but that the note is initially empty. If you provide null for this argument, the note is omitted from the dialog. The example updates the note each time the progress property changes. It updates the monitor's current value at the same time. Progress(). String message = String. It also waits for the progress to become more than the minimum value. If it calculates that the task will take more than 2. To adjust the minimum waiting period, invoke set. Millis. To. Decided. To. Popup. To adjust the minimum progress time required for a dialog to appear, invoke set. Millis. To. Popup. By the simple fact that this example uses a progress monitor, it adds a feature that wasn't present in the version of the program that uses a progress bar: The user can cancel the task by clicking the Cancel button on the dialog. Here's the code in the example that checks to see if the user canceled the task or if the task exited normally. Monitor. is. Canceled() . It provides the GUI and API to allow the program to do so easily. Use a progress bar if: You want more control over the configuration of the progress bar. If you are working directly with a progress bar, you can set it to be indeterminate, make it display vertically, provide a string for it to display, register change listeners on it, and provide it with a bounded range model to control the progress bar's minimum, maximum, and current values. The program needs to display other components along with the progress bar. You need more than one progress bar. With some tasks, you need to monitor more than one parameter. For example, an installation program might monitor disk space usage in addition to how many files have been successfully installed. You need to reuse the progress bar. A progress bar can be reused; a progress monitor cannot. Once the progress monitor has decided to display a dialog (or not), the progress monitor cannot do it again. Use a progress monitor if: You want an easy way to display progress in a dialog. The running task is secondary and the user might not be interested in the progress of the task. Progress monitor provides a way for the user to dismiss the dialog while the task is still running. You want an easy way for the task to be cancelled. Progress monitor provides a GUI for the user to cancel the task. All you have to do is call progress monitor's is. Canceled method to find out if the user pressed the Cancel button. Your task displays a short message periodically while running. The progress monitor dialog provides the set. Note method so that the task can provide further information about what it's doing. For example, an installation task might report the name of each file as it's installed. The task might not take a long time to complete. You decide at what point a running task is taking long enough to warrant letting the user know about it. Progress monitor won't pop up a dialog if the task completes within the timeframe you set. If you decide to use a progress monitor and the task you are monitoring is reading from an input stream, use the. Progress. Monitor. Input. Stream class. The following tables list the commonly used API for using progress bars and progress monitors. Because JProgress. Bar is a subclass of JComponent, other methods you are likely to call on a JProgress. Bar are listed in The JComponent Class. Note that Progress. Monitor is a subclass of Object and is not a visual component. The API for monitoring progress falls into these categories: Constructor. Purpose. JProgress. Bar()JProgress. Bar(int, int)Create a horizontal progress bar. The no- argument constructor initializes the progress bar with a minimum and initial value of 0 and a maximum of 1. The constructor with two integer arguments specifies the minimum and maximum values. JProgress. Bar(int)JProgress. Bar(int, int, int)Create a progress bar with the specified orientation, which can be either JProgress. Bar. HORIZONTAL or JProgress. Bar. VERTICAL. The optional second and third arguments specify minimum and maximum values. JProgress. Bar(Bounded. Range. Model)Create a horizontal progress bar with the specified range model. Method or Constructor. Purpose. Progress. MS Access - Quick and Easy Progress Bar. Microsoft Access - Quick and Easy Progress Bar. Within Access, there are times when a process is slow- running and appears to be non- responsive. The most logical way to convince a user to wait patiently is to use a progress bar. The question is how to do this within Access with as little as possible effort. Sys. Cmd ac. Sys. Cmd. Init. Meter, . Sys. Cmd ac. Sys. Cmd. Update. Meter, Counter ' Update Progress Bar. Sys. Cmd ac. Sys. Cmd. Remove. Meter ' Remove Progress Bar. In the first line of code, Sys. Cmd takes three parameters, the second being a text message that appears before the bar, and the third being a full counter value. This full counter value is the number of steps that represents a completed task. The progress bar will reflect the percentage that this counter value is of the full counter value specified in the first line of code.
