SWT ProgressMonitorDialog 与 Job [英] SWT ProgressMonitorDialog vs Job

问题描述

我想使用一个非模态的进度监视器，可以缩小到状态栏的右下角.

I would like to use a progress monitor that is non-modal and can be shrunk to the bottom-right of the status bar.

据我测试，ProgressMonitorDialog 可以正确地向用户显示进度条，并且可以使用下面的代码将其设为模态.但是，没有钩子可以将其缩小到状态栏的右下角.代码如下所示:

As far as I can tell from testing, ProgressMonitorDialog correctly displays the progress bar to the user, and can be made modal using the following code below. However there are no hooks to shrink it to the bottom-right of the status bar. The code kind of looks like this:

try {
    ProgressMonitorDialog pmd = new ProgressMonitorDialog(shell){
        @Override
        protected void setShellStyle(int newShellStyle) {           
            super.setShellStyle(SWT.CLOSE | SWT.MODELESS| 
                SWT.BORDER | SWT.TITLE);
            setBlockOnOpen(false);
        }  
    };
    pmd.run(true, true, new MyOperation());
} catch (final InvocationTargetException e) {
    MessageDialog.openError(shell, "Error", e.getMessage());
} catch (final InterruptedException e) {
    MessageDialog.openInformation(shell, "Cancelled", e.getMessage());
}

class MyOperation implements IRunnableWithProgress {
    @Override
    public void run(final IProgressMonitor monitor) throws 
      InvocationTargetException, InterruptedException {
        monitor.beginTask("start task", 10);

        // time consuming work here
        doExpensiveWork(monitor);

        monitor.done();
    }

当我使用 Job 进行测试时，作业按预期运行，但我没有得到视觉反馈.我的代码是这样的:

When I test with Job, the jobs run as expected but I get no visual feedback. My code is similar to this:

final ProgressBar progressBar = new ProgressBar(shell, SWT.SMOOTH);
progressBar.setBounds(100, 10, 200, 20);

// Setting the progress monitor
final IJobManager manager = Job.getJobManager();

final IProgressMonitor p = new IProgressMonitor() {

    @Override
    public void worked(final int work) {
        sync.syncExec(new Runnable() {
        @Override
        public void run() {
            progressBar.setSelection(progressBar.getSelection() + work);
        }
    });
    //....
}

Job job = new Job("test") {

    @Override
    protected IStatus run(IProgressMonitor monitor) {
        monitor.beginTask("start task", 10);

        // time consuming work here
        doExpensiveWork(monitor);
        // sync with UI
        syncWithUI();

        return Status.OK_STATUS;
    }

};
job.setUser(true);
job.schedule();

当用户最小化选项卡时，我缺少什么能够获得可以缩小到状态栏右下角的 ProgressMonitorDialog 版本?

What am I missing to be able to get a version of the ProgressMonitorDialog that can shrink to the bottom-right of the status bar when the user minimizes the tab?

推荐答案

不知道ProgressDialog怎么样，但是在使用jobs时显示进度，你必须设置

No idea how about ProgressDialog, but show progress while using jobs, you have to set

IWorkbenchWindowConfigurer configurer = getWindowConfigurer();
setShowProgressIndicator(true);

在org.eclipse.ui.application.WorkbenchWindowAdvisor.preWindowOpen()
