java - javaFX - resizing TextArea/other UI controls with main application window -
in javafx application need update handle window resizing. want when window gets bigger keep aligned same , have textarea grow proportionate window , similar when making smaller.
i set min , max height fit buttons on right-hand side (decreasing spacing little gets smaller).
i'm figuring out anchorpane not best option , hoping little guidance on better approach. text area using custom, extending styledtextarea (richtextfx api).
last spec want text field , button under text aligned text area , think pane make distance between textfield , button cumbersome approach (i planning on not making resizable).
image reference : text app image
any appreciated. if makes difference, entire layout inside borderpane center.

i don´t know if understood problem, if want resize pane may use hgrow property controls horizontal grow along anchorpane.left/rightanchor fixes left/right side of pane parent`s @ desired distance. try basic layout. can adapt code.
