JCombobox箭头消失 [英] JCombobox arrow disappears

问题描述

当未使用构造方法填充方法中的填充组合框时，组合框的箭头消失.

When the fill combobox in a method which is not placed in the constructor, the arrow of combobox disappears.

我尝试使用invokeLater方法，但是没有用.

I tried with the invokeLater method, but it did not work.

private void fillProduct(){
    this.VALID_FOR_PRODUCT.removeAllItems();
    this.VALID_FOR_PRODUCT.addItem(new JChooseItem("ALL", "Any"));
    for(Product product : Product.values()){
        this.VALID_FOR_PRODUCT.addItem(new JChooseItem(product.getName(), langHelper.getTrans(product.getTranslationKey())));
    }
}

推荐答案

我遇到了同样的问题，当我使用方法removeAllComponents()方法而不是removeAll()方法

I had the same issue, it happened when I used method removeAllComponents() method instead of removeAll() method
