如何设置摆动组件的大小 [英] How to set size of swing components

问题描述

我想自定义JTextField对象的高度和宽度。我尝试过使用setSize方法，将width和height作为维度传递，也作为int传递。但它们似乎都不起作用。我是否遗漏了某些内容，例如面板上的某些强制性方法调用或某些内容，以便大小定制有效？请帮忙。提前致谢。

I want to customize the height and width of the JTextField objects. I have tried with the setSize method, passing width and height as dimensions and as int as well. But none of them seems to work. Am I missing something, like some mandatory method call on the panel or something so that the size customization would be effective? Please help. Thanks in advance.

编辑：这里有一些代码：

Here is a bit of the code:

public class WestPanel extends JPanel{
private JLabel dateL;
private JTextField date;
public WestPanel(){
setBackground(Color.white);
setLayout(new GridLayout(1,2,0,0));
dateL=new JLabel("Date: ");
date=new JTextField("dd/mm/yyyy");
date.setSize(60,10);
add(dateL);
add(date);
//....remaining code....//

推荐答案

让布局管理器处理Swing组件的尺寸，但如果绝对必须，请将 setPreferredSize 与尊重的布局管理器结合使用该财产。

Let the layout manager take care of the dimensions of your Swing components, but if you absolutely must, use setPreferredSize in combination with a layout manager that respects that property.
