SDL_GetWindowWMInfo is not wrapped about go-sdl2

[aqiank]

I added a (temporary?) wrapper for it. Let me know if you have any issues with it.

How do I access SDL Version and SDL_SYSWM_TYPE seems to be a constant returned from the c side.

[aqiank]

I added a struct called SysWMInfo. You should be able to access the version number and subsystem now by doing something like:

sdl.VERSION(&info.Version)
status := window.GetWMInfo(&info)
subsystem := info.Subsystem
fmt.Println(status, info.Version.Major, info.Version.Minor, info.Version.Patch, subsystem)

Still need to figure out the best way to provide access to the union though (if we need it at all).

I'm trying to port this code over.

Ogre::String OSX_cocoa_view( SDL_SysWMinfo &info ) {
NSWindow * window = info.info.cocoa.window;
NSView * view = [window contentView];
return Ogre::StringConverter::toString( (unsigned long)view );
}

I was thinking maybe use the subsystem to generate different types.

Any idea how to provide access to the union?

[aqiank]

I added some methods to access them. You probably still need to write some C functions though to actually use it as I don't know about the underlying system. Any help here would be nice.

OSX:
returns unsigned long for NSView * view = [window contentView];

Win:
type WindowsInfo struct {
Window unsafe.Pointer
}

Window is an unsigned long

Linux:
Window is an Unsigned Long
Ogre::StringConverter::toString( (unsigned long)syswm_info.info.x11.window )

Not sure what surface is.

Summary: I have to turn these integer types into a string for ogre

macHandle := FormatUint(Window, 2)
params.AddPair("parentWindowHandle", macWindow)

I was able to get the information I needed through:

osxWindow := info.GetCocoaInfo()
windowString := strconv.FormatUint(uint64(_(_uint32)(osxWindow.Window)), 10)

Glad it worked for you! Sorry couldn't help much. Busy doing unrelated things in real life.

Might want to make a cast to unsigned long though for the window pointers.
