Swing/AWT/SWT :: Can't Get Gridbag Layout Components To Display As Required
May 4, 2014
I have quite a specific view for how I want my components layed out. No matter what I try I can get them to display how I want! I'm using three JPanels. There's a main panel that goes inside the tabbed pane. This main panel contains two other panels. The First panel is a gridbaglayout panel, with labels on the left column, and components on the right column. The second panel is underneath the second, and contains a label, and a button beneath it. THis uses a basic box layout, with one component per line. The label doesn't always appear (depends if a component is changed). With everything showing, this is how it looks so far:
However, I want the Labels on the left of the pane. The right hand column should be aligned horizontally and have more space from the labels. Ideally I'd like a gap between the last label/checkbox and the Note label.
This is my current code for the panel/s inside the tabbed pane window.
videoPanel = new JPanel();
applyVidBtn = new JButton("Apply Settings");
applyVidBtn.setVisible(false);
warningLbl = new JLabel("Note. Applying these settings causes a program restart.");
warningLbl.setVisible(false);
I wish to display a progress bar during a lengthy file translation process. When I created a ProgressBar class to do this and tested it with a short test program, it seemed to work fine. But when I add my ProgressBar class to a package containing various other classes, put that package in a jar file, and then execute the class using the progress bar from a menu in my main program, the frame of the progress bar shows up with the appropriate caption but the JLabel, JProgressBar, and JButton are not displayed. I have gone over my code numerous times and checked that the ProgressBar class constructor is getting the proper arguments.
// package gov.nasa.jpl.ephemeris; import java.awt.*; import java.awt.event.*; import javax.swing.*; /** * Progress bar with message text above the bar and a Cancel button below it */ public class ProgressBar extends JFrame { private boolean _cancelled = false; private JProgressBar _progressBar = null;
[Code] ....
I have also been wondering whether I need a separate instance of the border for each panel, or whether I can just create one instance and use it for all three panels.
I noticed that when building a UI programmatically in several steps the width/height of the Pane I use for layout is -1/-1. I read that this is the case until the actual rendering happens. Is there a way to force that earlier? Suppose I wanted to size other UI components (which are not visible initially) according to the size of another pane. How do I do that? Binding the properties does not do the job in the case that those components are not necessarily visible at the same time. Is there a trick to achieve that?
I'm trying to use netbeans GUI creator to create a chessprogram. However, the default "freeflow" layout is very difficult to work with. However, when I switch the layout to gridbag or border layout, I can't figure out really how to do anything. I don't know how to resize or position elements. Any good set of tutorials for using netbeans GUI creator with non standard layouts?
(I originally used absolute layout, which I can easily add and position elements in, but which I abandoned because i want the chessboard squares to resize when the window changes size).
i have very critical problem in my collage project i have try many code but still i cant solve this problem, i want to display image on jlabel or jpanel with respect of components size without use of drawimage method
ABC is a company that designs and prints personal business cards. The company has asked you to write a Java application to display the layout of the information in a typical business card order. Data items in a typical business card include the customer's name, address, city, state, postcode, home phone number, and work phone number.
Write, compile, and test a Java class that displays these data items in a command window. Alternatively, you could also create it using a dialog box. Please include appropriate comments in your class.
Please named your class BusinessCard(LIM).java. (eq. BusinessCardLIM.java)
I have a JPanel with vertical BoxLayout. It contains four components. I set the JPanel to LEFT_ALIGNMENT, which has no effect on its components. I set the first component to LEFT_ALIGNMENT, which has no effect. Only after I have set all four components to LEFT_ALIGNMENT do any of them align properly.
This suggests that it is impossible to have varying alignments in a container. They must all be the same alignment.
I accept that this is just the way things are: "Java works in mysterious ways." And I'm sure that it is possible to work around this limitation by stacking boxes that themselves have different internal alignments.
But I still wonder what in the world was going on in the minds of the Java developers. Is there a rational reason for this oddity?
This raises my most serious criticism of Swing: the hidden gotcha. Swing is a tangled mess of cross-connecting requirements that are impossible to divine by simple inspection of the documentation. If you want to use, say, a JRadioButton, it's not enough to study the documentation on JRadioButtons; you must also consult lots of documents for which there is no obvious connection to JRadioButton other than it being part of Swing.
I am trying to send a JPanel object to the server. While doing so I get the error -
java.io.NotSerializableException: javax.swing.filechooser.WindowsFileSystemView at java.io.ObjectOutputStream.writeObject0(Unknown Source) at java.io.ObjectOutputStream.defaultWriteFields(Unknown Source) at java.io.ObjectOutputStream.writeSerialData(Unknown Source) at java.io.ObjectOutputStream.writeOrdinaryObject(Unknown Source)
I have swing UI designed and I want the components to resize when the frame is manually resized. The design is as shown in the fig Project UI.jpg
The panel 4 and panel 5 will change their contents according to the list item clicked. Panel 4 just has text area but panel 5 a panel with numerous components as label, combo box, text field,check box will be present.Now if the frame resizes, I won't all the components to resize according to the frame size.
Let me explain by simplifying the GUI to a simple frame in which I have a JCheckbox and a JPanel mypanel.mypanel has a Textfield tf,JComboBox cmb as it's components.So now if I deselect the JCheckbox, all the components in the mypanel should be disabled. I used a code like:
but the components inside the panels are not disabled. In my actual program I have a large number of different kinds of components in mypanel.So disabling/enabling each of them on each actionPerformed of the mycheckbox will be laborious. Isn't there any way by which I can disable/enable the mypanel to disable/enable all the components in it?
I keep hearing these two term when it comes to painting in Swing, however, I'm not sure which is which. To my understanding is that the child components are the ones that already exist on screen (could be a JButton, JFrame, or custom painting) . and the parent components are the one to be added/drawn next. (hence, if we override the paintChildren() method when painting, the components that were already on the screen don't appear any more).
I trying to replace original (and empty) JPanel in JFrame with my own made one, components does no appear right, when I pass the mouse first button appears:
So I'm doing a basic MVC layout for a pretty basic game that I am making in order to understand the whole MVC layout. The game requires the user to move up/down/left/right via JButtons on the GUI. Since I'm using an MVC layout and my buttons are in a different class than the ActionListeners, I was wondering what the best way to add the action listeners are?
My IDE has a visual editor for creating Swing applications. The created application windows have no layout manager and use method "setBounds()" for placing Swing components on the application window. I have built an application that uses JInternalFrame. Each JInternalFrame is a separate and different "screen" for the user to interact with.
There are around 2,000 screens in the application and new screens are constantly being added as well as existing screens being modified. As a result, the top-level container - a JFrame - is a fixed size and is not resizable. I have now been asked to increase the size of the JFrame while maintaining the proportions of the screens.
Rather than manually editing the invocations of "setBounds()" on all the screens, any alternative way to achieve this? Also, is there a way to achieve this such that if, in future, the JFrame will again be resized, the screesn will automatically adjust?
My panel named panelIncomeInfo are not showing the components that I have added.
public class PayrollGUI { private JPanel panelIncomeInfo = new JPanel (); private JPanel panel = new JPanel (); private JPanel panelPayCheckInfo = new JPanel (); private JButton close = new JButton ("Close");
My JPanel when adding components to it will never make its self larger but it will make my components inside smaller even though I have set the minimum and preferred sizes for those components? I am using the GridBagLayout for my layout manager as I am trying to get used to it.

I'm trying to build a GUI that must look lik on the image above. There must be three JPanles, the one above, with buttons and combo boxes, must have fixed height and all three must have fixed vertical gaps between them. I'm trying laout after layout but somehow it's not working. I'm allowed to use only standard Swing layouts.
I like to adding a scrollbar to a jpanel with flowlayout but is imposible, i don't see the scrollbar. I've tried a thousand different ways but I have not accomplished anything.
Here is my code:
//Creamos el panel que contendra los botones de cada producto diferente package com.foolsrecords.tpv.tablaproductos.vista; //Hacemos todas las importaciones necesarias import com.foolsrecords.tpv.modelo.Producto; import com.foolsrecords.tpv.modelo.eventos.ControladorEventListener;
I have a stage,it has two layers scene, if user click the button,then change to another layer, and also can change back. It just like swing cardlayout. How can i implement cardlayout in JAVAFX?
I'm working on Ubuntu with resolution 1600*900; I used MigLayout to place the components of the application; but when I go with higher resolutions,components adjustment and alignment are not up to the mark.
Am trying to dynamically insert buttons (which will be presenting card in a frame) using grid layout.As shown image is getting inserted but its not fit in button.I tried Darryl's Stretch icon as well but of no support.
