boxlayout

问题 I have four buttons in a BoxLayout group. This is just a sample of two because it's all repeated code. I want to create a slight space between each button so they don't run into each other. I have tried practically every method in the .add(Box.Create....) and nothing worked. enter.add(Box.createVerticalGlue()); enter.add(Box.createHorizontalGlue()); //enter.add(new JSeparator(SwingConstants.HORIZONTAL)); JButton float = new JButton("LOWER"); float.add(Box.createVerticalGlue()); float.add(Box

问题 I try to make a very mini game. I have one JPanel , it uses a BoxLayout.Y_AXIS that contains three JLabel (name of JLabels = 1,2,3) I need a component inside that panel to anchor on South (so I use glue) The view result will be like this: 1 2 3 Then I have a JButton . If the user clicks the button, that JPanel adds a new JLabel (name of JLabel = neww) Here is the view result: 1 2 3 neww but I need something like this: neww 1 2 3 how should I do? Is it possible to handle it with BoxLayout ?

问题 edit: if you downvote this question, you may leave a comment to explain why, that will be more constructive. I obtain this unexpected result... ... using this code: import javax.swing.Box; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.SwingUtilities; public class TestAlignment extends JFrame { // Constructor public TestAlignment() { super("Test Alignment"); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); // Components to show JLabel

问题 As seen in the attached screenshot - the yellow line is from the underlying BoxLayout -oriented JPanel . Changing to BorderLayout removes the yellow line: Code example follows: import java.awt.BorderLayout; import java.awt.Color; import java.awt.Dimension; import java.awt.FlowLayout; import java.awt.event.WindowAdapter; import java.awt.event.WindowEvent; import javax.swing.BoxLayout; import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.WindowConstants; public class

问题 I'm trying to add multiple Jlabels in a Jpanel with Box layout, But i'm facing prolems on setting their setAlignmentX() . I'm reffering to an example from this site of Text bubble border and trying to pull out some examples from it. The jpanel is then added in Jscrollpane. My code is here !!! //Source :Andrew Thompson class TextBubbleBorder extends AbstractBorder { private Color color; private int thickness = 4; private int radii = 8; private int pointerSize = 7; private Insets insets = null;

问题 I have a parent JPanel with a Y_AXIS layout. The children of this container are all JPanels as well. The components are stacking fine, and are all alligned, but i want them to stick to the top of the parent JPanel so all excess space is in the bottom, and there is no extra space between the components. I have tried using glue, but i might be doing something wrong. I have also set the AllignmentX and AllignmentY to left and top respectively on all children. So, what i want is a stack of

问题 I have a question about nested BoxLayouts. I want to build a DropDownPanel which consists of 2 sub-Panels: a header at the top and a body at the bottom. The body is initially hidden. By clicking on the header you can toggle the visibility of the body and show its contents (like expand/collapse). In general this works fine. However there is some strange behaviour: If only one DropDownPanel is expanded and the other is collapsed then the collapsed DropDownPanel gets resized and floated to the

问题 I'm developing a game called GalaxyWar, and I am trying to make a map selection menu. I found a problem that when I am using a BoxLayout with BoxLayout.Y_AXIS on a JPanel with setAlignmentX(CENTER_ALIGNMENT) , the subcomponents (JPanel's) with assigned size, take up the entire height of the panel (all together), instead of the assigned height! Here is my code: scrollPane = new JScrollPane(); scrollPane.setBounds(160, 11, 452, 307); add(scrollPane); mapContainer = new JPanel(); mapContainer

问题 In the code below, by calling setAlignmentX with Component.LEFT_ALIGNMENT I expected to get a left aligned label over a centered slider. For some reason the label is also centered, seemingly regardless of what value is passed to setAlignmentX. What value must I pass to setAlignmentX to get it left aligned? package myjava; import java.awt.Component; import java.awt.Container; import javax.swing.BoxLayout; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JSlider; public

问题 The following code describes a button that is instantiated in a JPanel with a BoxLayout in Page Axis: private class AddInputSetButton extends JButton { public AddInputSetButton() { super("+"); setMinimumSize(new Dimension(100, 100)); pack(); addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent e) { addInputGroup(); } }); } } I have tried setSize(), setPreferredSize(), and setMinimumSize() to no avail, none of them resize the button. I am still relatively
