QT - CSS:焦点装饰 [英] QT - CSS: decoration on focus

问题描述

我正在尝试使用 CSS 为我的 QT 应用程序制作一个很酷的用户界面.

I'm experimenting a bit with CSS for making a cool user interface for my QT application.

我有这个问题:我有一个 QPushButton，当它处于焦点时，它上面有一个我想删除的矩形.这是一些屏幕截图:

I have this problem: I have a QPushButton and when it is on focus it has a rectangle on it that I want to remove. Here some screen-shot:

我尝试添加一些东西(背景色、文字装饰等)

I have tried to add something (backgroundcolor, text-decoration, etc)

QPushButton:focus

但它一直在突出显示..

but it keeps on highlighting..

一些提示?

这里是 QPushButton css 代码:

here is the QPushButton css code:

QPushButton
{
    color: #b1b1b1;
    background-color: QLinearGradient( x1: 0, y1: 0, x2: 0, y2: 1, stop: 0 #565656, stop: 0.1 #525252, stop: 0.5 #4e4e4e, stop: 0.9 #4a4a4a, stop: 1 #464646);
    border-width: 1px;
    border-color: #1e1e1e;
    border-style: solid;
    border-radius: 6;
    padding: 3px;
    font-size: 12px;
    padding-left: 5px;
    padding-right: 5px;
}

QPushButton:pressed
{
    background-color: QLinearGradient( x1: 0, y1: 0, x2: 0, y2: 1, stop: 0 #2d2d2d, stop: 0.1 #2b2b2b, stop: 0.5 #292929, stop: 0.9 #282828, stop: 1 #252525);
}
   
QPushButton:hover
{
    border: 2px solid QLinearGradient( x1: 0, y1: 0, x2: 0, y2: 1, stop: 0 #ffa02f, stop: 1 #d7801a);
}

QPushButton:focus {
    /*background-color: red;*/
}

推荐答案

突出显示的矩形可能是 QStyle::PE_FrameFocusRect 样式.摆脱它的唯一方法是实现自定义样式.幸运的是，Qt 提供了一种仅实现代理的方法，它在一般情况下使用另一种样式.对于您要实现的焦点矩形:

The highlighted rectangle may be the QStyle::PE_FrameFocusRect styling. The only way to get rid of it is by implementing a custom style. Fortunately, Qt provides a way to implement just a proxy, which uses another style in the general case. For the focus rectangle you'd implement:

class Style_tweaks : public QProxyStyle
{
    public:

        void drawPrimitive(PrimitiveElement element, const QStyleOption *option,
                           QPainter *painter, const QWidget *widget) const
        {
            /* do not draw focus rectangles - this permits modern styling */
            if (element == QStyle::PE_FrameFocusRect)
                return;

            QProxyStyle::drawPrimitive(element, option, painter, widget);
        }
};

qApp->setStyle(new Style_tweaks);
