为自定义 QT 类应用不同的 QSS 样式表 [英] Apply different QSS stylesheet for custom QT class

问题描述

我的 gui 使用的是 qss 样式表.它运行良好，但我想为我的自定义小部件定义不同的样式表.例如，QPushbutton 的样式效果很好，但我想为 MyQPushButton 应用不同的样式(从 QPushButton 扩展).

I am using a qss stylesheet for my gui. It works well but I would like to define a different style sheet for my custom widget. By example, QPushbutton's style works well but I would like to apply a different style for MyQPushButton (extends from QPushButton).

我尝试过这样的事情:

MyQPushButton
{
    color: #dcdcdc;
    // some code here
}

QPushButton
{
    color: #b1b1b1;
    // some code here
}

但是QPushButton的样式已经应用在MyQPushButton上.如何覆盖这种行为?

But QPushButton's style has been applied on MyQPushButton. How to override this behavior ?

推荐答案

如果您想为项目中的特定元素设置样式，可以这样使用；

If you want to style a specific element in your project, you can use it like that;

QPushButton#MyQPushButton
{
    color: #dcdcdc;
    // some code here
}

我假设您已经将新的 QPushButton 对象命名为 MyQPushButton，您可以像这样命名一个元素；

I assume that, you've already named your new QPushButton object as MyQPushButton, you can name an element like this;

QPushButton* myButton = new QPushButton;
myButton->setObjectName("MyQPushButton");

如果不命名元素，就无法访​​问它以赋予其覆盖样式.

Without naming your element, you can't access it to give it a overrided style.
