[英]How to make JTextField as wide as the window
I want to make the text automatically as wide as the window. 我想使文本自动和窗口一样宽。 I tried using text.setSize(window.getWidth(),20)
and text.setBounds(window.getWidth(),20)
, (where text is JTextfield), but the only way that seems to work is: static JTextField text = new JTextField(int numberOfColumns);
我尝试使用text.setSize(window.getWidth(),20)
和text.setBounds(window.getWidth(),20)
(其中文本为JTextfield),但是唯一可行的方法是: static JTextField text = new JTextField(int numberOfColumns);
I'm using GridBag layout. 我正在使用GridBag布局。
EDIT : I have edited example according to GridBagLayout. 编辑 :我已经根据GridBagLayout编辑了示例。
Use layout manager. 使用布局管理器。 It will automatically expands component according to window. 它将根据窗口自动扩展组件。 For example; 例如;
Jpanel panel = new JPanel(new GridBagLayout());
GridBagConstraints c = new GridBagConstraints();
c.gridx = 0;
c.fill = GridBagConstraints.HORIZONTAL;
c.gridwidth = GridBagConstraints.REMAINDER;
panel.add(textfield,c);
