C++ QTextFrameFormat::setBorderStyle方法代码示例

/*! Append a new message to the current session and scroll to the end of the message protocol and
    returns true if the action was successful. The \a messageColor defines the color of the message
    box and should be provided as a full-color (no dimming required) color, as it is automatically
