我正在尝试制作用于聊天的GUI,并且我连续放置了三个SWT控件.
不幸的是,我无法为他们找到漂亮的路线.
以下代码
Display display = new Display();
Shell shell = new Shell(display);
shell.setLayout(new GridLayout(3,false));
Label firstLabel = new Label(shell,SWT.NONE);
firstLabel.setText("PROMPT:");
firstLabel.setLayoutData(new GridData(SWT.BEGINNING,SWT.CENTER,false,false));
Text firstText = new Text(shell,SWT.NONE);
firstText.setText("hello");
firstText.setLayoutData(new GridData(SWT.FILL,SWT.FILL,true,false));
Button firstButton = new Button(shell,SWT.PUSH);
firstButton.setText("Say");
firstButton.setLayoutData(new GridData(SWT.BEGINNING,false));
shell.pack();
shell.open();
shell.setSize(400,300);
while (!shell.isDisposed())
{
if (!display.readAndDispatch())
display.sleep();
}
display.dispose();
给
即文本字段与按钮一样高,但文本不在其内部垂直居中.
如果以下方式编写文本代码
Text firstText = new Text(shell,false));
我会得到
最美丽的结果将由
Text firstText = new Text(shell,SWT.BORDER);
firstText.setText("hello");
firstText.setLayoutData(new GridData(SWT.FILL,false));
是的
但是按钮再次比文本略高.
UPDATE
人们说他们在非Windows平台上有很好的结果,但问题可能是如何控制SWT控件的填充/边距.
更新2
即使在最好的情况下,文本字段的高度也小于Windows上的按钮,结果与平台有关.
这是一个代码示例,可以让您了解如何解决您的问题:
public static void main(String[] args)
{
Display display = new Display();
Shell shell = new Shell(display);
shell.setLayout(new GridLayout(3,false));
Label secondLabel = new Label(shell,SWT.NONE);
secondLabel.setText("PROMPT:");
secondLabel.setLayoutData(new GridData(SWT.BEGINNING,true));
Text secondText = new Text(shell,SWT.BORDER | SWT.MULTI | SWT.WRAP);
secondText.setText("hello");
secondText.setLayoutData(new GridData(SWT.FILL,true));
Button secondButton = new Button(shell,SWT.PUSH);
secondButton.setText("Say");
secondButton.setLayoutData(new GridData(SWT.BEGINNING,true));
shell.pack();
shell.open();
shell.setSize(400,300);
while (!shell.isDisposed())
{
if (!display.readAndDispatch())
display.sleep();
}
display.dispose();
}
看起来像这样:
没有SWT.BORDER:
