Swing/AWT/SWT :: Resizing Images In Jbuttons In Grid Layout
Jun 21, 2014
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.
I am making a basic calculator using SWING.I want my JTextField to stretch across the top, above my buttons. All I can seem to get is it be the same size as one of my buttons.
How to implement GridLayout. In my applet, I want to make a grid of 2 rows and 2 columns. In each grid I want to add a Label and a TextField. I want the background to be red.
So my code would be?
import java.awt.*; import java.applet.*; import java.awt.event.*; public class GridLayoutApplet extends Applet implements ActionListener{ // construct components Label fNameLabel = new Label("First Name"); TextField fNameField = new TextField(20);
[Code] .....
I have read about panels and frames but, it is all confusing to me. How can you add a label and a TextField to one square of the grid?
import java.awt.GridLayout; import javax.swing.*; public class Screen { JButton start; JButton reset; JButton box[][] = new JButton[20][20];
[Code] ....
I am trying to place the buttons on the bottom. I tried a few different things but the grid layout keeps grabbing it and making them a part of the grid at the button.
I want my jrame should not be resized when clicking on maximize button of window.and for this i have put setResizable(false)in the constructor of class which extends Jframe.
I have an application that reads through a ResultSet... while I'm reading that ResultSet, I am creating new JButtons..... Now I need to add an ActionListener to those JButtons...... but they are not visible to the actionPerformed method. So I thought I'd try to add an ActionListener as I created the buttons with the following code:
final File file = new File(rs.getString(3)); SKPictureButton spb = new SKPictureButton(url,file.getName()); spb.addActionListener ( new ActionListener() { public void actionPerformed( ActionEvent e )
[Code] ....
However this seems a bit excessive to me..... I don't think I really want to be creating a new ActionListener class for each JButton do I ? Is there a better way to make the JButtons created in this method visible to the actionPerformed method ? I'm just gettin' back into the "Swing" of things in Java.... haven't coded it for a while.
I am in the middle of creating a chess application, and am currently working on laying out a list of moves on the right of the actual board. Specifically, I want to have a JLabel that says "moves" on top of a JList that contains the moves, on top of two buttons, labeled "<" and ">" respectively, to which I will eventually add functionality to take back and un-take back moves. Currently I have the first two parts down, but when I add my buttons,the other components are getting messed up.
I have all of these things in a vertical BoxLayout inside of a JPanel with a fixed width of 70, and a height that varies according to the size of the window (I overrode the getPreferredSize method of the JPanel). The two buttons are within their own JPanel with a grid layout with one row and two columns. Then I basically just add the moves list label, the movesList, and the panel housing the buttons to the larger panel, in that order.
However, I am encountering two problems. One, the buttons display the text "... " instead of "<" and ">" as if there is not enough room, although I'm pretty sure three periods take up more space than one less than or more than sign. The next is that, without the buttons at the bottom, the label reading "moves" is appropriately centered (or left aligned, I can't tell which) over the movesList, and you can read its whole text. However, when I add in the buttons at the bottom, the label of the top shifts over to the right and then reads "mov..." because it has run out of room.
Here is my code:
//move list movesListLabel = new JLabel("Moves"); //the components for the actual movesList come from another class with an object called pen, but I don't think this is the problem listModel = pen.getListModel(); JList movesList = pen.getMovesList(); JScrollPane listScroller = pen.getMovesListScrollPane();
I'm having issues with JButtons and painting methods, whenever I click a grid on the board, the buttons in the JPanel disappear. Here is the board class:
package GUI; public class Board extends JPanel implements Observer { /** * */ // private static final long serialVersionUID = 1L; private final int boardSizeX; private final int boardSizeY; private final int L = 20;
[Code] ....
I know the code is messy in places, this will be fixed later, just need some pointers on how to solve the JButton issue.
I've been reading that there's no way of making a JLabel user writable. What can I use inside the grid to make it writable with a keylistener? I'm making a crossword.
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?
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?
For example, say I have I BoxLayout with a few JButtons in it. How could I make it such that I could drag a JButton such that it could be in front or behind the others?
I've thought about using ComponentMover and just switching to a null layout right before moving it and switch it back right after like bellow, but I'm not sure how to make it keep the change in order.
import java.awt.LayoutManager; import java.awt.event.MouseEvent; public class LayoutComponentMover extends ComponentMover { private LayoutManager layout;
I am making an expert system using Jess about animals. I wanted to make an interface using Swing and so I did. I have a problem using group layouts. The application works fine but at the end a exceptions is thrown:
Exception in thread "AWT-EventQueue-0" java.lang.IllegalStateException: javax.swing.JLabel[,0,0,0x0,invalid,alignmentX=0.0, alignmentY=0.0,border=,flags=8388608,maximumSize=,minimumSize=, preferredSize=,defaultIcon=,disabledIcon=,horizontalAlignment=LEADING, horizontalTextPosition=TRAILING,iconTextGap=4,labelFor=, text=The animal is a cheetah.,verticalAlignment=CENTER, verticalTextPosition=CENTER] is not attached to a horizontal group
[Code] ....
The application ask the user some questions about the animal. When the expert system has enough information to know the animal it tells the name of the animal and shows a picture of it. The exception is thrown when the application has guessed the animal and shows the response.
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);
