在Mac OS X上从资源加载样式

Question

Using Firemonkey (FMX) in C++ Builder XE6, I am attempting to load a style in my project's cpp file.

Just before

Application->Initialize ()

I have

Fmx::Types::TFmxObject *style;
style = TStyleStreaming::LoadFromResource((unsigned int)HInstance, L"MacJet", RT_RCDATA);
TStyleManager::SetStyle (style);

where the style named MacJet has been loaded as a resource into the project at design time.

When I activate Win32 as the target platform, this runs fine, and the style shows properly in the application.

When I activate Mac OS X, however, I get an error on the style = ... line, stating

"Exception class SIGSEGV (11)."

When I remove the three lines above and run on Mac, the program loads up.

I'm new to cross-platform development, any ideas what is causing this error?

解决方法：在应用程序初始化之前，我没有使用资源并加载样式，而是在应用程序的主窗体中添加了TStyleBook，在设计时将样式添加到样式簿中，然后调用TStyleManager :: SetStyle（）来传递样式簿的Style属性，用于在主窗体的Create事件上设置应用程序的样式。
