在开发过程中,遇到了一个问题,比如说像下图这样的情况
假如要重新考试
那么对于软件来说,应该要做的一个措施就是,在用户点击Yes之后,将用户所有的已经选中的答案的状态设为未选中状态,那么对于不同类型的按钮怎么进行设置呢?
对于复选框QCheckBox,可以直接用setChecked来设置,示例如下:
//m_button是一个QCheckBox的数组 for(int i=0;i<10;i++) { m_button[i]->setChecked(false
); }
而对于单选按钮QRadioButton,一般单项选择题的四个选项中,只能选择一个,此时不需要加QButtonGroup,而对于n个单选题,则需要n个QButtonGroup来进行限制,否则所有单选按钮只能一个能被选中,可以通过这n个QButtonGroup将选中状态改为未选中。示例如下:
//m_BtnGroups是n个QButtonGroup组成的数组 for (int i=0;i<n;i++) { m_BtnGroups[i]->
setExclusive(false); m_BtnGroups[i]->checkedButton()->setChecked(false);
m_BtnGroups[i]->setExclusive(true); }
至此,n个被选中的按钮就被设置为未选中了。
