根据 Qt 6 中的frameShape使用CSS设置QFrame的样式

使用 Fusion 样式，带有 HLine 和 VLine frameShape 集的 QFrame 都显示为 1px 黑线。直到 Qt 5.15，外观都可以通过样式表进行更改。例如，这使得 QFrame 成为一条灰线：

QApplication application(argc, argv);
application.setStyleSheet(QStringLiteral(
    // This prevents HLine and VLine QFrames to be a black line
    "QFrame[frameShape=\"4\"],"
    "QFrame[frameShape=\"5\"] { "
        "color: palette(Mid); "
    "}"));

使用 Qt 6，此设置似乎被忽略。我还尝试使用一些文字颜色，例如 color: red 或 border: 1px Solid red 来查看它与 palette 值有关，但是设置仍然没有应用。省略 [frameShape=...] 选择器会使所有 QFrame 的样式类似于相应的设置，因此显然，这是关于 [frameShape=. ..] 选择器。

我尝试使用例如frameShape=\"0x0004\"以及例如frameShape=\"QFrame::HLine\"。这也行不通。

根据文档，QFrame::Shape 枚举保持不变。这是否尚未实现（我用 Qt 6.2.3 尝试过），或者是否必须在 Qt 6 中以另一种方式访问它？

原文

Using the Fusion style, both a QFrame with a HLine and VLine frameShape set are displayed as a 1px black line. Up to Qt 5.15, the appearance could be changed with style sheets. E.g. this made such a QFrame a gray line:

QApplication application(argc, argv);
application.setStyleSheet(QStringLiteral(
    // This prevents HLine and VLine QFrames to be a black line
    "QFrame[frameShape=\"4\"],"
    "QFrame[frameShape=\"5\"] { "
        "color: palette(Mid); "
    "}"));

Using Qt 6, this setting seems to be ignored. I also tried to use some literal color like color: red or border: 1px solid red to see it's about the palette value, but the setting is still not applied. Leaving out the [frameShape=...] selector makes all QFrames being styled like the respective setting, so apparently, this is about the [frameShape=...] selector.

I tried to use e.g. frameShape=\"0x0004\" and also e.g. frameShape=\"QFrame::HLine\". This also didn't work.

According to the docs, the QFrame::Shape enum remains unchanged. Is this not implemented yet (I tried it with Qt 6.2.3), or does one have to access this in another way in Qt 6?
