setWindowFlags(Qt::CustomizeWindowHint)用这个窗体不是模态框了

`setWindowFlags(Qt::CustomizeWindowHint)` 是用来设置窗体的外观和行为的，它将所有窗体标志设置为 `Qt::CustomizeWindowHint`，这表示窗体不会有默认的标题栏、最小化、最大化和关闭按钮。但是它并不会将窗体设置为模态对话框，仍然需要使用 `setModal(true)` 方法将窗体设置为模态对话框。例如：

dialog = QDialog()
dialog.setWindowFlags(Qt.CustomizeWindowHint)
dialog.setModal(True)
dialog.exec_()

这样设置后，窗体将没有默认的标题栏和按钮，并且能够以模态的方式弹出。

Qt::WindowFlags flags

Qt::WindowFlags is an enumeration type that defines various window flags that can be used to customize the properties of a window or widget in Qt. The flags can be combined using the bitwise OR operator to create a set of flags.

Some common flags that can be used with Qt::WindowFlags include:

- Qt::Window: This flag indicates that the widget is a top-level window.
- Qt::Dialog: This flag indicates that the widget is a dialog box.
- Qt::FramelessWindowHint: This flag indicates that the window has no frame or title bar.
- Qt::CustomizeWindowHint: This flag indicates that the window can be customized using the system menu.
- Qt::WindowStaysOnTopHint: This flag indicates that the window should always stay on top of other windows.

Example usage:

QWidget* myWidget = new QWidget();
Qt::WindowFlags flags = Qt::Window | Qt::CustomizeWindowHint | Qt::WindowStaysOnTopHint;
myWidget->setWindowFlags(flags);

This creates a new QWidget and sets its window flags to include the top-level window, the ability to customize the window with the system menu, and the window should stay on top of other windows.
