gridbaglayout

问题 I have a frame with the following layout of 3 JPanels. ---------------------------- | | | | l | | | e | //toppanel | | f | | | t |----------------------| | p | | | n | //bottompanel | | l | | | | | ---------------------------- I achieved this with the use of GridBagLayout This is the code for that layout public class UITests extends JFrame{ public UITests(){ setLayout(new GridBagLayout()); //the three main panels JPanel leftPanel = new JPanel(); JPanel topPanel = new JPanel(); JPanel

问题 I have following code to add panels dynamically to container with GridBagLayout. It should grow and display vertical scrollbar, not horizontal. But when I add too long text in JLabel in parent JPanel, it displays horizontal scrollbar, I want JLabel to break text as container shrinks, and also grows as the container grows. I've tried setting maximum width but the GridBagLayout not using it. I've also tried using something like but it makes the label's not growing when I resize the parent.

问题 I'd just made a layout in GridBagLayout for a split pane. Worked perfectly and looked right. I then needed to then add a scroll bar vertically only. Hence I have done that now. However the layout doesn't 'size' like before. It now stretches across rather sticking to the area of the pane shown. JSplitPane VPane = new JSplitPane(JSplitPane.VERTICAL_SPLIT,(new class1()),new JScrollPane(new class2(),ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS,ScrollPaneConstants.HORIZONTAL_SCROLLBAR_NEVER)); I

问题 I'm having trouble with a GridLayout in a GridBagLayout. I want my GridLayout fit the width of the GridBagLayout. I made an illustration of what i'm trying to do : But here is what i obtained : "Test, version : 1.5, Disponible" is a GridLayout with 1 columns and 3 rows. "Mitramail, version 1.0, Disponible" is another GridLayout with 1 columns and 3 rows too. I'm trying to adding them in another GridLayout with x row and 2 columns. so normally they should be next to each other, but they are

问题 I was recently introduced to GridBagLayout to substitute the vanilla JPanel layout, but I am having trouble working with the functions like gridwidth/height and gridx/y. I am not sure how they work exactly in changing the size of the GUI and the positions of the buttons. Below is a code my professor gave me to use for reference, and I tried fiddling with certain numbers but the results never turned out to be what I expected to happen, and I am not sure why. EDIT 1: To clarify, I am wondering

问题 I'm creating a GUI that should have buttons on top, a view screen in the middle, and at the bottom, an area with labels and text entry fields which change based on which button is pressed. The main panel on which everything lays is a GridBagLayout. The panel which holds the text entry fields is a CardLayout. I feel as though I've set the GridBagConstraints and everything else as it should be, but it comes up nothing as expected. I imagine there is a problem with how I've set the

问题 I noticed an issue with the setHorizontalScrollBarPolicy(ScrollPaneConstants.HORIZONTAL_SCROLLBAR_AS_NEEDED) resizes the height content when the scrollbar gets added (due to the content going over the width). The Code... import javax.swing.*; import javax.swing.border.Border; import java.awt.*; public class TestGui extends JFrame { //************************************************************************************** //************************************* Constructor **********************

问题 I have a panel which is used as a part of card layout. The panel uses GridBagLayout . I add two components to it: JTextArea with fill set to BOTH and JTextField with fill set to horizontal. They are only taking up the horizontal space. // Chat card setup JPanel chatCard = new JPanel(new GridBagLayout()); gc = new GridBagConstraints(); gc.gridx = 0; gc.gridy = 0; gc.fill = GridBagConstraints.BOTH; gc.weightx = 2; chatArea = new JTextArea(); chatCard.add(chatArea,gc); gc.gridx = 0; gc.gridy = 1
