Bom dia pessoas,
Estou fazendo uma tela aqui com JavaFX, contendo um GridPanel de duas colulas como container, e dentro de uma das colunas deste GridPane, um outro GridPane com uma coluna e oito linhas, que por sua vez recebe alguns ComboBox, TextFields e por fim o TreeView que apresenta problema.
Inicio a aplicação com a tela maximizada, e tudo ocorre bem. Porém, quando minimizo a janela, o TreeView não é redimensionado da forma que eu queria, ficando um bom pedaço da sua parte inferior escondida (dá pra se notar pela ausência da linha da base dele).
Tentei de todas as formas fazer com que ele redimensione. Tentei usar a porcentagem de cada linha desse GridPane, também passar um tamanho mínimo e máximo para a TreeView, e não obtive sucesso.
Vou postar o código logo abaixo, tanto do FXML quando do controller e a classe principal.

Se alguém tiver alguma ideia de como resolver esse redimensionamento, ficarei muito grato.
Muito obrigado desde já, abraços!
PS: o Controller ainda está vazio porque ainda estou fazendo a tela primeiro. Se não fui claro em algo, podem perguntar a vontade.
