Java swing 1.6 Textinput就像firefox吧
ted*_*ted 4 java swing awt jbutton jtextfield
我想创建一个看起来像firefox地址栏的textwidget /组件.我的意思是一个Textfield,它允许我在场内放置小按钮(例如取消/重装/ ......)
我尝试通过创建自定义布局管理器来自定义JLayeredPane,该管理器最大化Textfield,并将其余部分从右到左放置.我的问题是这给了绘画问题,我不会总是看到我在文本字段中添加的项目.这可能与Jython有关,我试着提供java.lang.Integer(1)给JLayeredPane.add.然而,层的排序与文档所说的完全相反.
为了实现这个目的,我派生了我自己的JLayeredPane类并重新定义paint了调用paintComponents哪个反过来遍历所有组件并调用他们的paint方法,从文本框开始,其余的后来.
但是我并不总是立即得到更新,这意味着按钮被隐藏/仅部分显示,我无法与按钮交互.
- 我有什么可以在屏幕上看到更新(它隐藏在缓冲区？))
- 我怎样才能使它与按钮交互？
- 如何缩短Texxtfield,以便文本在到达Textfield的末尾之前开始滚动到前面,这样文本就不会被按钮隐藏？我仍然希望Textfields区域在按钮下方扩展
编辑:在我使窗口变小之后,按钮仅显示在正确的位置,之后它也是可点击的
编辑2:我自由地将答案归结为此,隐藏了很多按钮代码/不必要的东西

可能是简单的使用JMenuBar,例如Auto Complete ComboBox/JFextField
import java.awt.ComponentOrientation;
import javax.swing.*;
public class MenuGlueDemo {
public MenuGlueDemo() {
JMenuBar menuBar = new JMenuBar();
menuBar.add(createMenu("Menu 1"));
menuBar.add(createMenu("Menu 2"));
menuBar.add(createMenu("Menu 3"));
menuBar.add(new JSeparator());
menuBar.add(new JButton(" Seach .... "));
menuBar.add(new JTextField(" Seach .... "));
menuBar.add(new JComboBox(new Object[]{"height", "length", "volume"}));
menuBar.add(Box.createHorizontalGlue());
menuBar.add(createMenu("About"));
JFrame frame = new JFrame("MenuGlueDemo");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.add(menuBar);
frame.pack();
frame.setVisible(true);
}
public JMenu createMenu(String title) {
JMenu m = new JMenu(title);
m.add("Menu item #1 in " + title);
m.add("Menu item #2 in " + title);
m.add("Menu item #3 in " + title);
if (title.equals("About")) {
m.setComponentOrientation(ComponentOrientation.RIGHT_TO_LEFT);
}
return m;
}
public static void main(String[] args) {
javax.swing.SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
MenuGlueDemo menuGlueDemo = new MenuGlueDemo();
}
});
}
}

我可以简单但只是一个文本输入和容器中的一些按钮具有适当的布局,并实现[Textfield ...] [B1] [B2],但我想[Textfield [B1] [B2]]
使用适当的LayoutManager
