Qt气球提示 [英] Balloon-tips with Qt

问题描述

在我的Qt应用程序中，我想使用如

In my Qt application, I'd like to use balloons/balloon-tips as shown in the Windows user experience guide (not the system tray balloons).

Qt支持吗?我什么都没找到是否有一个开放源代码库(Qxt没有它)?创建自己的最佳方法是什么?

Is this supported by Qt? I haven't found anything. Is there an Open Source library out there for this (Qxt does not have it)? What's the best way to create that myself?

推荐答案

要在Qt 5.12中使用私有类QBaloonTip，您需要执行以下操作:

To use private class QBaloonTip in Qt 5.12 you need to do the following:

1)将QT += widgets-private添加到您的PRO文件中，以便能够包含私有标头

1) add QT += widgets-private to your PRO file to be able to include private headers

2)#include <QtWidgets/private/qsystemtrayicon_p.h>在您的源文件中

然后调用静态方法showBallon()或实例化它，然后调用baloon().但这实际上仅适用于系统任务栏，并且是一个私有API，可以随时更改.我个人不会使用它.但是，如果您想知道它的呈现方式，请查看 https://code.woboq.org/qt5/qtbase/src/widgets/util/qsystemtrayicon.cpp.html#_ZN11QBalloonTip10paintEventEP11QPaintEvent

Then call static method showBallon() or instantiate it and call baloon(). But it is really only for system tray and it is a private API, which can change any time. I personally would not use it. But if you want to know how it is rendered, have a look at https://code.woboq.org/qt5/qtbase/src/widgets/util/qsystemtrayicon.cpp.html#_ZN11QBalloonTip10paintEventEP11QPaintEvent
