I got this working with Swing although I found it hard to make the user interface look good. Thus I'm trying to do the same in JavaFX. In the original Swing app, I create a thread which starts the parsing of files in the folder the user selected. It works like this: Find out total number of files to parse - The number of files and the number of

问题 So, I have a very very simple application that is supposed to handle downloading certain files and updating them into a certain directory. The application has a simple interface with a Status Bar that should tell the user how the download process is going. So far, so good. I have a few implementations of classes that extend the javafx.concurrent.Task class. Those classes handle the downloading and saving of files for each system, taking care of the particularities for each one. The download

问题 I'm using PyQt4 to display a progress bar in my application, but I want it to also be seen on the taskbar, just like many programs such as winRAR and google chrome do. Is there a way to make that happen? 回答1: Yes, you'll want to setup your QProgressBar (not QProgressBarDialog) and insert into QStatusBar (or QMainWindow.statusBar()) with the insertWidget(), then use removeWidget to remove it when you're done with it. 回答2: in PyQT5 you must use addWidget() class ExampleApp(QtWidgets.QMainWindow

问题 It's not so much the action bar, as much as it is creating a custom progress bar that I need help with.

问题 This question already has an answer here : Inno Setup: How to manipulate progress bar on Run section? (1 answer) Closed last year . This is similar to this question: Inno Setup Simple progress page for Run section If I'm adding some MSI files to my Inno Setup script, I can install these files from the [Run] section. At that time the progress bar shows 100% and shows the StatusMsg above the progress bar. I want manually set the value of the progress bar in the [Run] section, say a value of 50%

问题 In an Android application I run a task in a separate thread. While the thread is running it updates a progress bar in the main window to let the user know what's going on. The problem is, that if a user starts the thread a second time the progress bar won't be reset. It will just sit on 100% without doing anything. The whole source is available on github. As an example take the BackupThread and JsonBackup (the main class). Note that "RestoreThread" shows the same behaviour, but I assume that

问题 I'm trying to make a software with good UI , but i'm not professional in VB ... How can i make a circular progress bar ? for Example 回答1: How about just drawing your own using GDI+.
