Opening JDialog with SwingWorker?

由 被刻印的时光 ゝ 提交于 2019-11-28 13:13:39
I have a project J2SE that use JPA. In some JDialogs I do returns getResultList() and populate JTable, JComboBox, JList etc. at constructor of class. So when I will create any instance for these dialogs sometimes are slow. I think use SwingWorker and JProgressbar and create a (loading) to open JDialogs is a good solution, but I don't know how to do this. I'm trying this. // JProgressbar progress = new JProgressBar(); //custommer dialog JDialog custommer = new JDialog(); //here slow because I have List<Customer> and others lists custommer.setModal(true); private void openDialogs(JDialog dialog)

JProgressBar not triggering propertyChange on setProgress

问题 I've read many different articles about JProgressBar...including the dodgy code found over at Java; here. Most indicate you need a SwingWorker to get things happening properly, which makes perfect sense, I understand that much. I am finding that when I call setProgress(value) to update the progressbar, it's not triggering the propertyChange event most of the time. I've checked the value I'm passing to setProgess and it definitely changes every time, so I'm not sure if it's just firing the

JProgressBar too fast

问题 I am trying to add a progress bar. everything works and i don't get any error. But the progress bar goes from 0% to 100% without even going through the values between it (I mean it's too fast, and the users are unable to see the progress bar blocks filling in) pr = new JProgressBar(); pr(0); pr(true); .. public void iterate(){ while (i<=20000){ pr.setValue(i); i=i+1000; try{ Thread.sleep(150); }catch (Exception e){ e.printStackTrace(); } } } When i button is clicked i call the iterate()

Basic Indeterminate JProgress Bar Usage

由 痴心易碎 提交于 2019-11-28 03:52:35
问题 I simply want to have an indeterminate JProgressBar animate in the bottom left corner of my frame when a long download is being done. I've looked through many tutorials, none of which are clear to me. I simply want to have it animate while the file is being downloaded in the background. Each way I've tried this, it doesn't animate the progress bar until after the download is done. I need help knowing where to place my download() call. class MyFunClass extends JFrame { JProgressBar progressBar

Pretty alternative to JProgressBar? [closed]

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 3 years ago . I'd like a nice progress bar for long running processes. Are there any pretty alternatives to JProgressBar out there, specifically for indeterminate processes? I'm thinking of Web-2.0-looking twirls, spinning wheels, what have you. Imaginary bonus points for no cost, LGPL-licensed stuff. ;) 回答1: You might like

Change colors for JProgressBar with Nimbus?

由 岁酱吖の 提交于 2019-11-28 00:13:52
does anyone know how to change the colors for JProgressBar when you use Nimbus LookAndFeel? I have overridden the whole nimbusOrange -Default Value, which change all ProgressBar-Colors and any other nimbusOrange . (InternalFrame - minimize Button) here with nimbusBase (blue) UIDefaults defaults = UIManager.getLookAndFeelDefaults(); defaults.put("nimbusOrange",defaults.get("nimbusBase")); Better is to write a own Painter and set this to the UIManager via UIManager.put("ProgressBar[Enabled].backgroundPainter", myPainter); If You want to change the Color for only a single ProgressBar instance,

Setting the colors of a JProgressBar text

由 我的梦境 提交于 2019-11-27 18:18:33
问题 I have these progress bars: I'm trying to set the color of the TEXT of the progress bars, without changing the background color or the color of the progress bar itself. As far as I can tell, setForeground() sets both the text and the bar color? Is there a way to do one without the other? 回答1: Ah ha - looks like I can modify the UI: setUI(new BasicProgressBarUI() { protected Color getSelectionBackground() { return Color.black; } protected Color getSelectionForeground() { return Color.white; }

Draw a String onto a ProgressBar, like JProgressBar?

由 旧巷老猫 提交于 2019-11-27 16:34:33
问题 I recently started working with JavaFX, and started making FX versions of my custom Swing components. One of them was a count down timer, in which a JProgressBar was involved. I would draw the current time onto the bar using it's setString(String) method. Unfortunately, there does not seem to be such a method with JavaFX's ProgressBar . The closest thing I saw to what I was looking for was this: (source) I don't know if this would require a whole new custom component, or just a class like
