gridbaglayout

问题 I am using GridBagLayout for the first time. I have a JFrame which has 2 panel's inside. The frame is of width 1200 and height 800. The left most JPanel has the width of 800 and height of 800. The right most panel has the width of 400 and height of 800. When they are rendering using GridBagLayout they are both being shown with equal size. This is the code: public class DisplayFrame extends JFrame { public DisplayFrame() { //simple inheritance. super(title); setSize(new Dimension(1200, 800));

问题 I was trying to make a keyboard layout, where one can specify the buttons' width. Therefore, I made an attempt with GridBagLayout but without success. To illustrate my problem I did a simple example, where I expected to obtain this (Button2, Button4, Button5, Button6): but instead I get Button4 and Button6 of double width. The code is: package views; import java.awt.BorderLayout; import java.awt.EventQueue; import java.awt.GridBagConstraints; import java.awt.GridBagLayout; import javax.swing

问题 I am dinamically generating a layout which requires to use relative sizes, the only way I found to do it without using an external Java layout library is GridBagLayout's weightx and weighty. At this point it has been working exactly as I need with one small exception. When I have one column containing two JPanels with a space distribution of 66.6% and 33.3% respectively and then another column with 3 JPanels using 33.3% of the space each one of them, the 33.3% of the first column is not the

问题 I'm new to Java Swing and I have been struggling to start the GridBagLayout from top left corner so that c.gridx=0 c.gridy=0 will put my object on the top left corner. I'd appreciate if you could help me by telling what I need to do after this point: JPanel panel = new JPanel(new GridBagLayout()); frame.add(panel); GridBagConstraints c = new GridBagConstraints(); I know that I have to use NORTHWEST or FIRST_LINE_START constants, but I don't know how. I tried to do it this way' but it did not

问题 I have 5 components in a JPanel. Everything is looking smooth with the first 4 component's I've added. However, when I try adding a 5th component to the JPanel, the spacing between the components change for whatever reason! Without 5th component: First Name: [..............] Last Name: [..............] With: First Name:---------------- [.............] Last Name:----------------- [.............] What is your favorite sport: Pretend the dashes above between label and textfield is space The

问题 I have this vexing source written to demonstrate a layout for a game screen mentioned on another question. It puts buttons (or labels, choosable at start-up) into a GridBagLayout . If you choose to not use buttons when prompted (before the GUI appears) the entire GUI is nice and compact with no gaps. But if you choose to use buttons it will (if your set up is like mine) look something like this.. Note the red horizontal lines. That is the BG color of the panel showing through. Those lines are

问题 Im currently wanting to construct a table type of layout for JPanels. I found out there is a TableLayout for Java but I don't how to import it. On the other hand i found out there is a GridBagLayOut which also can construct a table like layout.But it seems more complicated. Any advice. 回答1: Here is an SSCCE of using a TableLayout, (Introduction to TableLayout) import javax.swing.JButton; import javax.swing.JFrame; import layout.TableLayout; public class TestTableLayout { public static void
