Javafx TextInputDialog禁用ok按钮

Question

I am using the JDK8u45 and I am trying to use the text input dialog but is there a way to disable the ok button until I enable it? I checked the java docs and did not see a disable feature. Is there another way to do this in java 8 if this does not work?

Answer 1

Lookup the button and invoke setDisable on it.

TextInputDialog dialog = new TextInputDialog();
dialog.getDialogPane().lookupButton(ButtonType.OK).setDisable(true);

disable is a property, so you could bind the value to some condition if you wish (rather than explicitly calling setters to disable and re-enable it).
