如何获取安装在Qt设备中的应用程序图标列表

qt

如何获取安装在Qt设备中的应用程序图标列表,qt,symbian,qicon,Qt,Symbian,Qicon,我正在使用Qt应用程序，我想在其中创建一个QListWidget，其中包含设备上安装的所有应用程序的名称及其图标。 因此，我无法从本文中的代码中获取每个应用程序的所有应用程序名和UID。 但我也无法获得应用程序图标。我尝试了这两种方法，但在这里我遇到了一些问题，比如如何将CGulIcon转换为QIcon，以及如何将CApaMaskedBitmap转换为QIcon 我怎样才能做到这一点呢？好吧，关于图标的事情，看看这个：CGullIcon有一个函数，返回位图，一个CFbsBitmap。完成后，请看

我正在使用Qt应用程序，我想在其中创建一个QListWidget，其中包含设备上安装的所有应用程序的名称及其图标。 因此，我无法从本文中的代码中获取每个应用程序的所有应用程序名和UID。 但我也无法获得应用程序图标。我尝试了这两种方法，但在这里我遇到了一些问题，比如如何将CGulIcon转换为QIcon，以及如何将CApaMaskedBitmap转换为QIcon

我怎样才能做到这一点呢？

好吧，关于图标的事情，看看这个：CGullIcon有一个函数，返回位图，一个CFbsBitmap。完成后，请看以下内容：然后创建一个新的QIcon（QPixmap）（QPixmap=已转换的图标）。因此，最有可能的情况是，首先将其传递给CFbsBitmap，然后使用FromSymbnacfbSBitmap（）的QPixmap

如果我没有错的话，CApaMaskedBitmap是CFbsBitmap的一个子类，所以它的工作原理应该是一样的

对于获取应用程序及其UID，请尝试查看以下内容：

对于图标，请查看以下内容：CGullIcon有一个返回位图的函数，一个CfBbitMap。完成后，请看以下内容：然后创建一个新的QIcon（QPixmap）（QPixmap=已转换的图标）。因此，最有可能的情况是，首先将其传递给CFbsBitmap，然后使用FromSymbnacfbSBitmap（）的QPixmap

如果我没有错的话，CApaMaskedBitmap是CFbsBitmap的一个子类，所以它的工作原理应该是一样的

要获取应用程序及其UID，请尝试查看以下内容：
