I have created a swing application which has a TrayIcon, this has one button that has the following code:
displayItem.addActionListener(
new ActionListener(){
public void actionPerformed(ActionEvent e) {
trayIcon.displayMessage("Hello Title","Hello World", TrayIcon.MessageType.WARNING);
}
});
[/highlight]
I have another class which I run via the following:
Thread counter = new Thread(new regCheck());
counter.start();
And within this "start" method I want to be able to wait 10 seconds and then trigger the popup that appeared within the original class. I think that the right method of achieving this is to create a function within my original class causes the popup.
public void display(String a, String b) {
trayIcon.displayMessage(a,b, TrayIcon.MessageType.WARNING);
}
However I have two issues here:
-firstly I dont know how to get the original trayIcon image from the method it was initialized into this new method.
-secondly I dont know how to trigger this event from the other class. Here is the method that I tried (but doesnt work)
window w = new window();
w.display("a","b");
This doesn't work because window's main begins to run and endlessly creates multiple windows and TrayIcons. What is the correct way to implement this sort of behaviour?
I've constructed 4 different levels and allow the user to select the level they want to play from a central JPanel in a Card Layout system. My problem is that once a level is completed, I can't switch the JPanel which is displayed to start the next level, since I don't know how to access the original JPanel which acts as a driver for the other panels.
In this method, I tried to select the currently selected panel, then select the index 0 JPanel and re-select the current one to simulate the ChangeListener event, However, when the user comes back from a JDialog, I don't have this opportunity to do so, How do I trigger the ChangeListener of the tabbedPane (JTabbedPane) conveniently?
public void refreshPanels() throws SQLException, IOException { parent.clearSelection(); centerPanel.removeAll();
// change data set first, if the JDialog // is displayed however, since no more JPanels
I have two classes. One constructs my a rectangle using Graphics2D (the class is called Rectangles). The second takes a user input for the triangle, which I am passing back to the first class. I am trying to trigger a repaint of class one from the action listener I have on a button in the second class. how to trigger this event?
Is it possible to make it so that when the popup box comes up I will only be able to click on the box? For example, I would be browsing the internet while the program is running and then the box pops up and I am forced to answer the question before I can click on anything else. If it is possible, how do I do it?
I am having issue with jmenu popup in netbeans. It only sometimes works. Sometimes I don't get a java popup at all. Sometimes my File and Edit options are completely missing. This is what my code looks like.
import javax.swing.*; public class menu { /** * @param args the command line arguments */ public static void main(String[] args) { // TODO code application logic here JFrame f = new JFrame(); f.setVisible(true);
Is there a way to connect the popupmenu to the right Object (JFrame).
(Something like SwingUtilities.getWindowAncestor(popupmenu)
I've created 2 JFrames each with the same MouseClass. When you click on the RMB a pop menu is shown with a background item. When clicked on the background item only the last created JFrame changes his background.
Below is my simplified code. I'm probably not thinking like a good OO'er.
I have a case where I want to float a modeless popup on top of all other content. Seems like a Popup is ideal for this. Except for the following annoyances:
I don't see any way to tie its position to some owner window. You can supply an initial anchor position, but I noticed that if I drag the frame of the app window containing the JavaFX application, the Popup remains where it is and can actually appear outside the bounds of the App! I find this very disconcerting. I suppose I could bind its position to the screen coords of the Stage, but it would seem that I should not have to do this.If I minimize the app, the Popup remains visible. Rather odd given that when I called Popup.show(Window), you would think when the owner Window got hidden it would hide the owned Popups too. Again, I could probably bind to some property on the Stage, but like (1), it seems you should not have to do this.
I haven't tried this while embedding the Scene in a browser. I certainly hope that these Popups should not be allowed outside the bounds of the browser window. That spells trouble.
I am developing my college's project in JSP using jquery to open a magnific popup when user clicks on a link and the in the magnific Popup must be fetched from Mysql and i tried two approaches for this:
1. magnific Popup type is ajax here i passed the variable value in the link of href (after '?') to another JSP page where connection to database is created and queries are written in JSTL to fetch data and show this in magnific Popup .. But i failed in this approach, don't know in another JSP page the data without having database connection is loaded in the magnific Popup easily but not database data..
2. magnific Popup type inline here i need to pass the variable value in the same page between different tags..
We created one web application which runs on tomcat 7.0.35 using spring mvc 3.0 . Its working perfectly on 32-bit windows machine in IE 8 on Windows 7 OS, when we tried to run this on 64-bit windows 2008 Server, jquery is not working. Also I populate data from Pop-up JSP to parent JSP, and it works 3/10 times only and does not work always.
We used the following jquery plugins in our project
I have a combobox with this PopupMenuListener. All works fine, except that the popupMenuWillBecomeInvisible method does not capture the selection made and neither does it show the selection.
PopupMenuListener pmlMqMessagePurged = new PopupMenuListener() { @SuppressWarnings("unchecked") public void popupMenuWillBecomeVisible(PopupMenuEvent arg0) { try { JdbcSqlServerDataSource ds = new JdbcSqlServerDataSource( DbConnectionURL.UToolDbHostName, 0,
[Code] .....
The popupMenuWillBecomeInvisible does fire but the System.out.println() returns 'nul'l as answer to the value i have selected from the combobox.
Main screen leftsecond screen rightswing portal application is visible on two screens. If you open a context menu (right mouse) on the right screen, the context menu open on the left (Main) screen instead of the right.
How do you declare methods for a class within the class whilst objects of the class are declared else where?
Say for instance, I have a main class Wall, and another class called Clock, and because they are both GUI based, I want to put a Clock on the Wall, so I have declared an instance object of Clock in the Wall class (Wall extends JFrame, and Clock extends JPanel).
I now want to have methods such as setClock, resetClock in the Clock class, but im having trouble in being able to refer to the Clock object thats been declared in the Wall class.
Is this possible? Or am I trying to do something thats not possible? Or maybe I've missed something really obvious?
Regarding the lifecycle of servlet , in headfirst servlet i can find :
You normally will NOT override the service() method, so the one from HttpServlet will run. The service() method figures out which HTTP method (GET, POST, etc.) is in the request, and invokes the matching doGet() or doPost() method. The doGet() and doPost() inside HttpServlet don’t do anything, so you have to override one or both. This thread dies (or is put back in a Container-managed pool) when service() completes.
How can I call the doGet method of the subclass from the superclass. i am not getting this .
I have a quick polymorphism question. I have a parent class and a sub class that extends the parent class. I then declare an array of parent class but instantiate an index to the sub class using polymorphism. Do I have to have all the same methods in the child class that I do in the parent class? Here is an example of what I mean.
public class ParentClass { public ParentClass(....){ } public String doSomething(){ } } public class ChildClass extends ParentClass { public ChildClass(....)
[Code] ....
Is polymorphism similar to interfaces where the child class needs all the same methods?
I want to know is there any way we can call parent class method using child class object without using super keyword in class B in the following program like we can do in c++ by using scoop resolution operator
class A{ public void hello(){ System.out.println("hello"); } } class B extends A{ public void hello(){ //super.hello(); System.out.println("hello1");
i want to write a class in such a way that i should get the current execution time of another class which is running. I searched in net but it shows only how to calculate the time duration of the current class which is running. But as per my way, i need the execution time of one class from another class. How to do this ?
