如何设置提示文本字符串的颜色、字体和大小？

Question

I am trying to change the properties of a String made from TextField::setPromptText using JavaFX.

This code:

TextField shapeField = new TextField();         
shapeField.setMaxWidth(100);   
shapeField.setPromptText("Circle, Triangle, Hexagon");
             
TextField fillField = new TextField();         
fillField.setMaxWidth(100);
fillField.setPromptText("Red, Green, Grey");

Currently sets the prompt text to this:

I want to be able to make the font smaller and change the colour. How would I do this?

Answer 1

For color you need: -fx-prompt-text-fill: red; and you can change font size with but you need to add an event to check if text is empty then use your prompt text size and when not the actual size of the text (edited): -fx-font-size

for example:

tf.setStyle("-fx-prompt-text-fill: red;\n" + "-fx-font-size: 26pt;");
