yes, here is an example of such:
> var windowToolkitKind = WindowToolkitKind.Darwin
>
>> {.passL: "-framework AppKit".}
>>
>> type NSOpenPanel {.importobjc: "NSOpenPanel*", header: "<AppKit/AppKit.h>",
>> incompleteStruct.} = object
>>
>> proc newOpenPanel: NSOpenPanel {.importobjc: "NSOpenPanel openPanel",
>> nodecl.}
>>
>> template wrapObjModalCode(body: untyped) =
>> {.emit: """ NSAutoreleasePool* pool = [NSAutoreleasePool new]; NSWindow*
>> keyWindow = [NSApp keyWindow]; NSOpenGLContext* glCtx = [[NSOpenGLContext
>> currentContext] retain]; """.} body {.emit: """ [pool drain]; [glCtx
>> makeCurrentContext]; [glCtx release]; [keyWindow makeKeyAndOrderFront: nil];
>> """.}
>>
>> proc callDialogFileOpen*(title: string, buttons: seq[DialogButtonInfo] =
>> @[]): string =
>>
>>
>> wrapObjModalCode:
>> let dialog = newOpenPanel() let ctitle : cstring = title var cres:
>> cstring {.emit: """ [`dialog` setCanChooseFiles:YES]; `dialog`.title =
>> [NSString stringWithUTF8String: `ctitle`];
>>
>> if ([`dialog` runModal] == NSOKButton && `dialog`.URLs.count > 0) {
>> `cres` = [`dialog`.URLs objectAtIndex: 0].path.UTF8String;
>>
>> } """.}
>>
>> if not cres.isNil:
>> result = $cres
unfortunately it is only for this panel...
