javafx 如何让ComboBox铺满GridPane的整列

例如下图:现在“位置”和“有无边框”我是放在一个GridPane中，我希望“有无边框”对应的的ComboBox和上面的“位置”对应的TextField一样充满整列

Answer 1

试试GridPane的这个方法：
public static void setHgrow(Node child,
Priority value)

Sets the horizontal grow priority for the child when contained by a gridpane.
If set, the gridpane will use the priority to allocate the child additional
horizontal space if the gridpane is resized larger than it's preferred width.
Setting the value to null will remove the constraint.

Parameters:
child - the child of a gridpane
value - the horizontal grow priority for the child

这个方法我尝试过了，用在TextFiled上面有用，但是用在ComboBox上面是无效的。。

Answer 2

给有无边框 加 width 并且赋值

追问

你的意思是给GridPane加上边框还是给ComboBox加上边框？
