当我按下按钮时，我想回显当前选择的列表，但它所做的只是运行我分配给按钮的功能。我希望它检测是否选择了一个列表，如果没有显示另一个 yad 窗口说“请选择一个任务/提醒以使用此按钮！”，但如果选择了某些内容，则显示一个 yad 窗口说“您选择：列表名称列表日期“ 谢谢。

我所要做的就是将 yad 窗口存储为变量；然后，我可以得到选定的列表。

option="$(yad --separator='\n' --title="$AppName" --window-icon="${DIRECTORY}/icons/logo.png" --center --width='300' --height='300' --text-align="center" --text="Welcome to $AppName! \nWhat would you like to do?" --button="Add new Task/Reminder"!"${DIRECTORY}/icons/install.png"!'Create a new Task/Reminder':2 --button="Delete Task/Reminder"!"${DIRECTORY}/icons/uninstall.png"!'Delete Task/Reminder':3 --list --column=Task/Reminder "${items[0]}" --column=Date "${items[1]}")"

echo $option

if [ "$option" -eq "" ]; then
  yad --title="Error" --text="You didn't select a Task/Reminder! Please go back and try again"
else
  # Do something with the selected items.
fi
