Question

应用程序有一个带配置的简短弹出菜单。一段时间后配置增长了，我想调用对话框而不是弹出菜单。但是当我在鼠标事件上调用对话框时，会发生奇怪的事情。 mouseReleased在堆栈中被多次调用。每次调用相同的组件（正确的组件）时，都不是因为从几个重叠的组件调用相同的事件。

看来，我根本无法调用对话而不是弹出菜单，好吧。但是发生了什么？

适配器：

class ConfigTriggerListener extends MouseAdapter{
    ...
    @Override
    public void mouseReleased(MouseEvent ev) {
      if (ev.isPopupTrigger()) {                  <-- breakpoint

        cont.showScreenModal(ConfigDlg.class, DynProps.createFromValues(ConfigDlg.CONFIG_CONTROL_CLASS, ORundownConfig.class));
      }    
    }
}

为什么MouseReleased事件被堆叠（多次）？
