如何更改 contextMenu 默认鼠标按钮?
How to change contextMenu default mouse button?
我有一个 contextMenu 并将其添加到一个按钮中。当我在按钮上左键单击(PRIMARY)时,我希望显示 contextMenu。我怎样才能做到这一点?因为默认情况下只需右键单击即可。
我试过这种方法,但没有用
Button sortBy = new Button();
ContextMenu sortByMenu = new ContextMenu();
sortByMenu.addEventFilter(MouseEvent.MOUSE_PRESSED, ev -> {
if (ev.getButton() == MouseButton.PRIMARY) {
//does not do anything
}
});
sortBy.setContextMenu(sortByMenu);
菜单按钮
MenuButton
is a button which, when clicked or pressed, will show a ContextMenu
.
来自 javadoc 的示例代码:
MenuButton m = new MenuButton(
"Eats"
);
m.getItems().addAll(
new MenuItem("Burger"),
new MenuItem("Hot Dog")
);

你也可以考虑 ChoiceBox,这取决于你想做什么。
The ChoiceBox
is used for presenting the user with a relatively small set of predefined choices from which they may choose.
ChoiceBox<String> cb = new ChoiceBox<>();
cb.getItems().addAll(
"item1",
"item2",
"item3"
);
对于 select 选择列表中的 sortBy 排序字段,ChoiceBox 可能是一个不错的选择。
