GridBagLayout with glue : no fixed row height

旧巷老猫 提交于 2020-05-17 07:42:53
问题 I would like to create a panel, to which I can dynamically add sub-panels with fixed height. I tried using a glue component, but it does not work. I would like to achieve that the sub-panels are visible at the top of the gridbaglayout. Side problem is that when I keep adding sub-panels, they start to overlap because the JScrollPane isn't adjusting. However, when I resize the frame, both problems are solved. At this moment I don't see where I went wrong. Why does the glue component not take up

GridBagLayout does not display a component

问题 I wrote a component to display a circular progressbar. When I put it in BorderLayout everything looks fine. But it can't be seen when a GridBagLayout is set. p.setLayout(new GridBagLayout()); GridBagConstraints gbc = new GridBagConstraints(); gbc.gridx = 0; gbc.gridy = 0; p.add(north(), gbc); gbc.gridx = 0; gbc.gridy = 1; p.add(west(), gbc); gbc.gridx = 1; gbc.gridy = 1; p.add(bar, gbc); I have no idea whether it is the problem of setting the GridBagConstraints or other reasons. 回答1: But it

注:本文内容转自: Java Layout总结-GridBagLayout 。内容根据笔者理解稍有整理。 GridBagLayout 布局管理器 : 这就是最复杂的一个布局管理器了 , 网格包布局 . 在此布局中 , 组件大小不必相同 . GridBagLayout gb=new GridBagLayout(); ContainerName.setLayout(gb); 以上代码是让容器获得一个 GridBagLayout. 要使用网格包布局 , 还必须有其一个辅助类 ,GridBagContraints. 它包含 GridBagLayout 类用来定位及调整组件大小所需要的全部信息 . 使用步骤如下 : 1). 创建网格包布局的一个实例 , 并将其定义为当前容器的布局管理器 . 2). 创建 GridBagContraints 的一个实例 3). 为组件设置约束 . 4). 通过方法统治布局管理器有关组件及其约束等信息 5). 将组件添加到容器 . 6). 对各个将被显示的组件重复以上步骤 . GridBagContraints 类的成员变量列表如下 : 1 、 gridx— 组件的横向坐标; 2 、 girdy— 组件的纵向坐标; gridx=0,gridy=0 时放在 0 行 0 列, GridBagConstraints.RELATIVE 为默认值

问题 I'm having an issue when using GridBagLayout, everything seems to be working as intended but there's a small gap at the bottom of the JFrame that I can't seem to get rid of. This is the code I'm running... import java.awt.BorderLayout; import java.awt.Color; import java.awt.Dimension; import java.awt.FlowLayout; import java.awt.GridBagConstraints; import java.awt.GridBagLayout; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JPanel; public class Test { private JFrame

SetVisible(false) changes the layout of my components within my Panel

问题 How do I make the subpanels within my main panel stay where they are when I set one of the subpanels to be invisible? What I have looks like: [ (Panel1) (Panel2) (Panel3) (Panel4) ] When I do panel3.setVisible(false) it then looks like: [ (Panel1) (Panel2) (Panel4) ] I would like it to look like: [ (Panel1) (Panel2) (Panel4) ] I am using the GridBagLayout and my mainPanel declaration looks like: final JPanel panel = new JPanel(new GridBagLayout()); GridBagConstraints c = new

How to get component located in a specific gridx, gridy from a JPanel with GridBagLayout layout?

问题 I have a jpanel with gridbaglayout layout, in it i have several jtextfields, several jlabels, several jbuttons which get added dynamically. Therefore I cannot know their specific orders, hence cannot use panel.getComponent(count). I looked in the api if there is something like getGridx(int x) or getGridy(int y). Didn't find. Is there anything similar to those methods? 回答1: The simplest solution might be to use GridBagLayout#getConstraints(Component) and simply loop through all the components

GridBagLayout erratic resizing and displaying

你说的曾经没有我的故事 提交于 2020-01-06 21:21:49
问题 I'm making a program that uses a GridBagLayout in a container. My primary use for this is to have two JPanels, which occupy 75% and 25% of the horizontal space of the window. For some reason though, the two panels look more like 90/10, and when resizing, the smaller one rapidly changes in size, between it's apparent minimum size, and what I believe is the desired 25%. Here is the relevant code. frmReedreadV = new JFrame(); frmReedreadV.setBounds(x, y, width, height); frmReedreadV
