MRX's questions

我需要删除屏幕上用红线（左侧）指示的缩进。

如何实施？

我尝试使用setSpacing，但没有用。

此外，如果可以的话，很高兴知道如何删除小部件周围的白色选择框。（截图 2）

вы уверены? /да и нет我需要通过居中和调暗它（假设是半透明的灰色，都在同一个窗口中）在主窗口的顶部覆盖一个对话框（比如说小部件）。

如何实施？

我需要将按钮放置在其上方 frame，使其不在其中，而是在其顶部（覆盖）（出于个人原因，当我填充frame其中的所有元素时，无法显示）。

在当前版本的代码中，按钮位于 内部frame，我需要相同的实现，但位于frame. 如何实施？

我试图根据鼠标在屏幕上的位置隐藏鼠标，我编写了一个实时跟踪鼠标的代码，如果位置没有改变则隐藏光标。

但是我遇到了一个问题，当我更改鼠标类型时setCursor（

简而言之，鼠标根本不会隐藏，直到鼠标离开窗口并重新进入。（这是我的问题）

listwidget我需要在按下按钮时获取元素的索引。

期望：我点击一个按钮（不是一个元素）item 5并得到它的响应5 item。

现实：我最有可能只得到最后一个元素（19）的索引，因为我已经完成了循环。

如何连接按钮以使其始终提供元素的索引？

最小可重现示例：（仅作为示例进行，可能存在错误）

我在 Qt Designer 中创建了一个小部件，但是在 Qt Designer 中实现它时QListWidget出现了问题。
理论上，当您单击列表中的一个元素时，它应该被清除listwidget并且应该在其中绘制一个新的小部件 ( Ui_Widget)。
很可能，问题出在错误的类结构中，但我不知道如何正确构建它，实际上我得到了一个错误。

AttributeError：“Ui_Widget”对象没有属性“titlelabel_2”

如何将选择器的颜色（选择一个元素）从标准更改为我自己QListWidget，我尝试使用

self.listWidget.setStyleSheet("selection-background-color: black")

在MainWindow，但它只是没有改变。

我究竟做错了什么？

完整代码如下：

        self.titleLabel.setStyleSheet('''color: White; background-color:  #1C1C1C; font-size:24px; border-radius: 15px;
        min-height: 50px;
        max-height: 50px;
        min-width: 50px;
        max-width: 500px;
        ''')

        self.descriptionLabel = QtWidgets.QLabel()
        self.descriptionLabel.setWordWrap(True)
        self.descriptionLabel.setStyleSheet('color: White; background-color: #1C1C1C; max-height: 150px; border-radius: 15px;')

        self.vBoxLayout = QtWidgets.QVBoxLayout()
        self.vBoxLayout.addWidget(self.titleLabel, 0)
        self.vBoxLayout.addWidget(self.descriptionLabel, 1)
        self.vBoxLayout.setSpacing(0)

        i = 0
        for list in listdata:

            customQWidget.setTitle(list["tittle"])
            customQWidget.setDescription(list["description"])
            self.pixmap.loadFromData(httpx.get(list["url"].content))

            customQWidget.setIcon(self.pixmap)

            item = QtWidgets.QListWidgetItem(self.listWidget)

我想使用Python和PySide2或PySide6 library创建这样的东西（视觉上） 。它应该是一个带有图片、标题和描述的列表（我有所有这些数据）。

不幸的是，我没有找到如何大致实现它。
你能建议在这里使用哪个元素更好以及从哪里开始。
我为图片道歉，这个布局是在膝盖上制作的，元素应该是一样的，这很明显。
