A simple "yes/no" message

Messages.showYesNoDialog(message, title, yesText, noText, Messages.getQuestionIcon())

Perfect, thank you Vladimir.

To my embarrassment, I can never remember the code myself and have to search in my plugin code where I know I used it before.

Looking at the code of Messages.showYesNoDialog, it just calls MessageDialogBuilder.yesNo. It looks like it might be there just for backwards compatibility or something. I wonder if it is better to call it directly?

import com.intellij.openapi.ui.MessageDialogBuilder;
...
final MessageDialogBuilder.YesNo dialogBuilder =
    MessageDialogBuilder.yesNo(title, message)
        .yesText(yesText)
        .noText(noText)
        .icon(Messages.getQuestionIcon());
boolean answer = dialogBuilder.guessWindowAndAsk();
