由 半腔热情 提交于 2019-12-18 09:02:55
问题 I am currently waiting for a very important announcement and I have created a simple application to check every 30 minutes whether the announcement was made or not When the announcement is made, I want a window to pop up and inform me about it. The window is just a simple JFrame that has some text in it. I have a class called Announcement. Inside this class I define another class for the frame called Form, so I have something like this: class Form{ public Form(){ //create frame and show it

Show JDialog on Windows taskbar

问题 I'm trying to display a JDialog in Windows. How do I show a JDialog (like JFrame ) on my Windows taskbar? 回答1: A dialog itself cannot have a task bar entry, but you can construct a frame that does not have any visible effect and use it as a parent for the dialog. Then it will look like the dialog has a task bar entry. The following code shows you how to do it: class MyDialog extends JDialog { private static final List<Image> ICONS = Arrays.asList( new ImageIcon("icon_16.png").getImage(), new

问题 I've made my own SwingWorker example to get familiar with how it works. What I'm wanting to do is the following: When the button is clicked I want a progress bar appear until the task is done I want to simply remove the progress bar and add a string to the dialog. When the button is clicked, the progress bar comes up but never goes away. (never removes the progress bar after 10 seconds and never places the label up) Here is an SSCCE: package swingtesting; import java.awt.event.ActionEvent;

How to handle oversized JDialog

由 岁酱吖の 提交于 2019-12-13 03:52:59
问题 I'm developing a JDialog which will have three sections, one on the top of the other: customer general information, list of customer addresses and list of orders. The list of customer addresses may grow arbitrarily large and this causes the dialog to grow beyond the screen height. Thus, calling pack() before displaying it does not work because the packed dialog height is still too big for the screen height. This calls for a scroll pane. But I would have to set the dialog's preferred size to

Java Open URL Inside of a JFrame

由 大城市里の小女人 提交于 2019-12-13 03:33:30
问题 I was wondering if there is a way to open a URL inside of a JFrame or JDialog. I need this to protect the URL.

With a network sniffer like Ethereal, it would be trivial to know which requests are made by your application. Security

问题 I have an action defined in the same package as the JDialog. I want to bind the Java Dialog`s close button to this action, without using window listeners. Just set once this action to the button. Can you help me do this, please? Thank you 回答1: The following code should achieve what you need using a WindowAdapter as a WindowListener. The windowClosing method is called exactly once upon pressing the close button. If you plan to add an alternative Close-Button you can always fire a windowClosing
