[英]Creating textField with unique name for each in a loop
im beginner level programmer on Java. 我是Java的初学者级程序员。 I would like to create textField in a for loop but i also want it to have a unique name (for calling after loop).
我想在for循环中创建textField,但我也希望它具有唯一的名称(用于在after循环中调用)。 For ex.
对于前。 I have this loop;
我有这个循环;
for (int i =0;i<x;i++)
{
Composite composite_10 = new Composite(composite_20, SWT.BORDER);
composite_10.setBackground(SWTResourceManager.getColor(230, 230, 250));
composite_10.setBounds(x1, y1, 542, 76);
txtBaseSeri = new Text(composite_10, SWT.BORDER);
txtBaseSeri.setMessage("Base Seri");
txtBaseSeri.setToolTipText("");
txtBaseSeri.setBounds(x2, y2, 95, 21);
txtBaseSeri.setText("41");
txtBaseSeri.setTextLimit(7);
}
Here, I want the second Textfield have a name like txtBaseSeri1, then txtBaseSeri2... so that i can call them after exiting the loop. 在这里,我希望第二个Textfield的名称像txtBaseSeri1,然后是txtBaseSeri2 ...,以便退出循环后可以调用它们。 Is there any way to do that ?
有什么办法吗? Thanks in advance..
提前致谢..
I want the second Textfield have a name like txtBaseSeri1, then txtBaseSeri2 - Is there any way to do that?
我希望第二个Textfield具有一个类似txtBaseSeri1的名称,然后是txtBaseSeri2-有没有办法做到这一点?
No. Use an ArrayList
instead and add your text fields to that list, for example like this: 否。请改用
ArrayList
并将文本字段添加到该列表中,例如:
List<Text> txtBaseSeri = new ArrayList<>();
for (int i = 0; i < x; i++) {
// ...
Text txt = new Text(composite_10, SWT.BORDER);
// ...
txtBaseSeri.add(txt);
}
Afterwards, you can access each Text
object through its index, like 之后,您可以通过其索引访问每个
Text
对象,例如
Text first = txtBaseSeri.get(0);
Text second = txtBaseSeri.get(1);
// ...
or you can loop through them, like 或者您可以遍历它们,例如
for (Text txt : txtBaseSeri) {
// in each loop iteration, txt will be set to the next element
// ...
}
