如何使QCheckBox只读，但不灰显 [英] How to make QCheckBox readonly, but not grayed-out

问题描述

任何用于只读选项的好方法，但也可以不灰显（几乎不可见）。

Any good way to make a checkbox readonly, but also not grayed-out (hardly visible).

1. 我使用 setEnabled（bool）可以工作，但是复选框是灰色的，难以读取


2. 对切​​换信号和复位状态。但是，我需要一个标志来确定该框是否是只读的，然后重置检查状态，意味着我需要创建自己的 CheckBox 类。



3. setCheckable 也不工作，它不允许我设置一个选中的状态：

1. I have used setEnabled(bool) which works, but the checkbox then is grayed-out and hardly readable
2. I can react on a toggle signal and reset the state. But I would need a kind of flag to determine if the box is read-only and then reset the check state, means I need to create my own CheckBox class.

3. setCheckable does not work either, it does not allow me to set a checked state at all:

    cb = this->ui->cb_RealWorld->isCheckable();
    this->ui->cb_RealWorld->setCheckable(true);
    this->ui->cb_RealWorld->setChecked(someValue);
    this->ui->cb_RealWorld->setCheckable(cb);

启用/停用并接受灰色样式。

So the best thing I have is to use enable/disable and accept the grayed out style.

在样式表示例之后，我是希望我可以设置一个禁用复选框的样式，如启用。到目前为止失败了。更具体：如示例中所示更改图标不适用于我，也许是因为我使用的是Windows，并且图标不在示例中的路径下。

Following the stylesheet examples I was hoping I could set the style of a disabled checkbox like the one of an enabled. Failed so far to do so. More specific: Changing the icon like in the examples does not work for me, maybe because I am using Windows and the icons are not available under the path as in the examples.
