问题描述
我正在做Eclipse插件开发。我正在使用 MessageDialog 类。可以在。
I am doing Eclipse plugin development. I am using the class MessageDialog. The API can be found here.
我想添加一个链接，就像我在消息中对此处所做的一样 MessageDialog 。
I want to add a link like I did about with "here" in the message of the MessageDialog.
这是我在做什么：
String errorMessage = "You have received an error. Please visit " + URL_NEEDED_HERE
MessageDialog.openError(getShell(), "Get Existing Data Sources Error", errorMessage);
URL一直显示为字符串。
The URL keeps showing up as just a String. Is it possible for it to show as a link?
推荐答案
正如@ greg-449所说， MessageDialog 不支持链接。如果您不介意骇人听闻的方法，则可以节省一些工作并覆盖 createMessageArea ，例如：
As @greg-449 said, the MessageDialogdoes not support links. If you don't mind the hackish approach, you can save some work and override createMessageArea like so:
@Override
protected Control createMessageArea( Composite composite ) {
Image image = getImage();
if( image != null ) {
imageLabel = new Label( composite, SWT.NULL );
image.setBackground( imageLabel.getBackground() );
imageLabel.setImage( image );
GridDataFactory.fillDefaults().align( SWT.CENTER, SWT.BEGINNING ).applyTo( imageLabel );
}
if( message != null ) {
Link link = new Link( composite, getMessageLabelStyle() );
link.setText( "This is a longer nonsense message to show that the link widget wraps text if specified so. Please visit <a>this link</a>." );
GridDataFactory.fillDefaults()
.align( SWT.FILL, SWT.BEGINNING )
.grab( true, false )
.hint( convertHorizontalDLUsToPixels( IDialogConstants.MINIMUM_MESSAGE_AREA_WIDTH ), SWT.DEFAULT )
.applyTo( link );
}
return composite;
}
};
代码从 IconAndMessageDialog 复制并只需用 Link 小部件替换 Label 。
The code is copied form the IconAndMessageDialog and just replaces the Label with a Link widget.
另外，您也可以这样覆盖 createCustomArea ：
Alternatively you can override createCustomArea like so:
@Override
protected Control createCustomArea( Composite parent ) {
Link link = new Link( parent, SWT.WRAP );
link.setText( "Please visit <a>this link</a>." );
return link;
}
这是将自定义控件添加到 MessageDialg ，但导致布局略有不同：
This is the designated way to add custom controls to a MessageDialg but leads to a slightly different layout:
