GridBagLayout panels alignment

I have a little issue with the GridBag Layout Manager. I am trying to display 9 panels like this: To do so, I separated the Grid like this: For the panels 1 to 7 there is no problem, they show up just as I want. But the issue starts with the panels S8 and S9 . As you can see, the S8 and S9 takes up half the frame, but I can't make it display like this. The S8 ends at the start of S4 , and the S9 begins at the end of S4 , I cannot handle the half space. Only way I figured out is to put the S8 and S9 panel in another panel which takes all the frame width - but surely there must be a proper way

How to get GridBagLayout to respect minimum size of a button or panel?

℡╲_俬逩灬. 提交于 2019-11-27 17:52:23
问题 In the following GridBagLayout code, I'm expecting the specified minimum size of JButton btn2 to be respected when the JFrame is resized to be made smaller. But when I make the JFrame smaller, the btn2 gets smaller than its minimum size and then vanishes. Can someone point me in the right direction of what I'm doing wrong? Maybe I have to set the minimum size of the JPanel that contains the buttons? Any help is appreciated, thanks! JFrame frame = new JFrame(); frame.setSize(400,300); frame

How can I properly center a JPanel ( FIXED SIZE ) inside a JFrame?

Hi all! I'm trying to solve an -apparently- simple problem, but I cannot fix it. I'm working on a sample application with Java/Swing libraries; I have a JFrame and a JPanel. I just want to achieve the following objectives: JPanel MUST be centered inside the JFrame. JPanel MUST have ALWAYS the size that is specified with setPreferredSize() method. It MUST NOT be resized under this size. I tried by using a GridBagLayout: it's the ONLY way I can do it. See the sample below: /* file StackSample01.java */ import java.awt.*; import javax.swing.*; public class StackSample01 { public static void main

I see that GridBagLayout positions it's children with center alignment within cells. How to align left or right?

Why does this GridBagLayout not appear as planned?

I was trying to achieve the end result required in Setting an arbitrary width in GridBagLayout . For easy reference, here it is: This is the current result: Button number and row is shown in the form 1,1 , followed by the number of columns (2) declared for this cell. As you can see, it starts with buttons 1,1 (3) and below it 1,2 (4) being the same width, while declaring different numbers of columns. Can anyone determine how to correct the code? The current code: import java.awt.*; import javax.swing.*; import javax.swing.border.EmptyBorder; public class KeyBoardLayout { private JComponent ui

How to lock aspect ratio of a gridLayout in Java?

▼魔方 西西 提交于 2019-11-27 08:03:17
问题 Is there an easy way of locking the aspect ratio of a GridLayout component in Java Swing ? Or should this be done on the JPanel containing that layout ? 回答1: GridLayout effectively ignores a component's preferred size, but you can control the aspect ratio of whatever is drawn in paintComponent() , as shown in this example. The rendered shape remains circular (1:1 aspect), while (nearly) filling the container in the narrowest dimension. Resize the frame to see the effect. Addendum: For example

Looking for general method for GridBagLayout component creation

假装没事ソ 提交于 2019-11-27 02:17:18
I'm designing a GUI with 20 or so components: 10 labels, 4 text fields, 4 buttons, and 2 text areas. Using GridBagLayout seemed a great idea. But with all the instance variables required to do it by the book for each component (i.e., not reuse), a general method for adding components seemed a must. I really thought this could work: (Note: HORIZ is abbreviation for GridBagConstraints.HORIZONTAL; CENTER is abbreviation for GridBagConstraints.CENTER.) public static void addComponent(Container f, Component c, int x, int y, int w, int h, int ipadx, int ipady, float wtx, float wty, int fill, int
