向Qt样式表添加特异性时丢失样式 [英] Losing style when adding specificity to a Qt stylesheet

问题描述

这是我的代码：

const QString STYLE_SHEET = "background-color: rgba(x,x,x,y);"
                            "border: 1px solid gray;"
                            "border-radius: 0px;"
                            "border-top: 1px solid red;"
                            "border-bottom: 1px solid blue;"
                            "border-radius: 0px;";

稍后在代码中应用SS，如下所示：

The SS is applied later in the code like this:

QWidget * myWidget;
myWidget = new QWidget(parent);
myWidget.setObjectName("myWidgetName");
myWidget.setStyleSheet(STYLE_SHEET);

它像一个冠军，除了边框渗入一个子QFrame。如果我通过用下面的括号添加特殊性STYLE_SHEET：

It works like a champ except that the borders bleed into a child QFrame. If I add specificity to STYLE_SHEET by bracketing it with the following:

const QString QWidget#myWidgetName { }

STYLE_SHEET停止应用。它解决了向下流到孩子QFrame，但我的QWidget失去了它的风格。

The STYLE_SHEET ceases to apply. It solves the bleed down to the child QFrame but my QWidget loses its style. And what good is a QWidget without style?

推荐答案

const QString STYLE_SHEET = "QWidget#myWidgetName {\n"
                            "    background-color: rgba(x,x,x,y);\n"
                            "    border: 1px solid gray;\n"
                            "    border-radius: 0px;\n"
                            "    border-top: 1px solid red;\n"
                            "    border-bottom: 1px solid blue;\n"
                            "    border-radius: 0px;\n"
                            "}\n";
