java - How to remove text from textflow in javafx? -

-

i'm new javafx , trying display large amount of text in textflow. displays fine, cannot figure out how delete text.

so i'm trying delete text nodes textflow so

textflow.getchildren().removeall();

but when , add textflow, shows after text displayed there. text there removed , show added text beginning of textflow.

i guess have somehow rerender view of textflow, don't know how. how delete , add text anew?

removeall(...) remove values pass parameters: in case there none, doesn't remove anything. use

textflow.getchildren().clear();
