qt remove resize handle

To remove the resize handle in Qt, you can use the following steps:

1. Set the Qt::MSWindowsFixedSizeDialogHint flag: Set the Qt::MSWindowsFixedSizeDialogHint flag for the window flags of the widget using the setWindowFlags method. This flag disables the resize handle for the widget.

cpp widget->setWindowFlags(widget->windowFlags() | Qt::MSWindowsFixedSizeDialogHint);

1. Update the window flags: Call the winId method on the widget to ensure that the window flags are updated.

cpp widget->winId();

By following these steps, you can remove the resize handle in Qt by setting the appropriate window flags for the widget.
