Does anyone know what i need to do be able to open a Finder dialog from within my application. So it shows a new Finder window with my file selected.
Is there a Juce utility function that lets me do this.
I know there is file.startAsProcess(); but that wouldn’t work as it try to open my file instead of just locating it.
for windows : strVectorItemPath is juce::String.
if (strVectorItemPath.isNotEmpty())
{
juce::File projectFile(strVectorItemPath);
if (projectFile.exists())
{
//This code is opens the file location and highlights/select the file in explorer.
strVectorItemPath = strVectorItemPath.replace(T("/"), T("\\")); // just in case the path has unix style separator
juce::String file = "/select," + strVectorItemPath;
ShellExecute(NULL,"open","explorer", file.toUTF8(), NULL, SW_SHOWNORMAL);
}
} for mac : fileToOpen is char
NSString * path = [NSString stringWithCString:fileToOpen encoding:NSASCIIStringEncoding];
if( path != 0L && [path length] != 0 )
{
if([ [ NSFileManager defaultManager] fileExistsAtPath : path] == YES)
{
NSString *parentDirectoryPath = [path stringByDeletingLastPathComponent];
if (parentDirectoryPath != 0L)
{
BOOL operationStatus = [ [NSWorkspace sharedWorkspace] openFile:parentDirectoryPath];
if (operationStatus)
operationStatus =[[NSWorkspace sharedWorkspace] selectFile: path inFileViewerRootedAtPath:parentDirectoryPath];
}
}
} Well, that’s the enormously complex way of doing it.
But personally I think I’d go for:
myFile.getParentDirectory().startAsProcess()But that wouldn’t highlight the file
ah, right! Well yes, if highlighting the file is important, then that’s a good solution!
It’s a good candidate for something to add to the library, actually.
It would be an honour if it would make it to juce. 
This is the version of code Justin had shared with me for pc.
bool revealFile(const File &sourceFile)
{
jassert(sourceFile.exists());
if (!sourceFile.exists())
return false;
// use the full path to explorer for security
TCHAR winDir[MAX_PATH];
uint32 len = GetSystemDirectory(winDir, MAX_PATH);
// Need enough space to add the trailing backslash!
if (!len || len > MAX_PATH - 2)
return false;
winDir[len] = L'\\';
winDir[++len] = L'\0';
juce::String explorerParams;
explorerParams << L"/select,";
explorerParams << (L'\"');
explorerParams << (sourceFile.getFullPathName());
explorerParams << (L'\"');
HINSTANCE result;
if ((result=::ShellExecute(NULL, _T("open"),_T("explorer.exe"), (const TCHAR*)explorerParams,
winDir, SW_SHOWNORMAL)) <= (HINSTANCE) 32)
return false;
return true;
} and my mac version of code
bool revealFile(const File &sourceFile)
{
BOOL operationStatus = NO;
NSString * path = [NSString stringWithCString:sourceFile.toUTF8() encoding:NSASCIIStringEncoding];
if( path != 0L && [path length] != 0 )
{
if([ [ NSFileManager defaultManager] fileExistsAtPath : path] == YES)
{
NSString *parentDirectoryPath = [path stringByDeletingLastPathComponent];
if (parentDirectoryPath != 0L)
{
BOOL operationStatus = [ [NSWorkspace sharedWorkspace] openFile:parentDirectoryPath];
if (operationStatus)
operationStatus =[[NSWorkspace sharedWorkspace] selectFile: path inFileViewerRootedAtPath:parentDirectoryPath];
}
}
}
return operationStatus;
}If I get time I would put in juce and try it.
explorerParams << L"/select,";
explorerParams << (L'\"');
explorerParams << (sourceFile.getFullPathName());
explorerParams << (L'\"'); Add a /n, so…
explorerParams << L"/n,/select,";
This is so you get two windows opening up should you select two files in the same folder.
And I’ve got an add on the mac…just make sure you have a ScopedReleasePool at the top!
Justin
I will do the easy part of the work keep you informed. 
. You do the correction part of it.
How can I forget that :oops: .
Sorry to be picky Vishvesh! 
NSString stringWithCString:sourceFile.toUTF8() encoding:NSASCIIStringEncodingThrows alarms up to me.
Julian has a nice juceStringToNS in mac_native_headers that’ll keep everything all unicode friendly.
I know that .
The code I posted was my version of code which I had used outside of juce. I will be posting the version of code which can sit inside juce. Got the mac version running currently I am testing the windows version. After it’s done I would personally send you the post URL for code review 
.
Here is the code( Justin, Jules and gekkie100 )
For mac with juceStringToNS .
bool File::revealFile() const throw()
{
const ScopedAutoReleasePool pool;
BOOL operationStatus = NO;
NSString * path = juceStringToNS (getFullPathName());
if( path != 0L && [path length] != 0 )
{
if([ [ NSFileManager defaultManager] fileExistsAtPath : path] == YES)
{
NSString *parentDirectoryPath = [path stringByDeletingLastPathComponent];
if (parentDirectoryPath != 0L)
{
BOOL operationStatus = [ [NSWorkspace sharedWorkspace] openFile:parentDirectoryPath];
if (operationStatus)
operationStatus =[[NSWorkspace sharedWorkspace] selectFile: path inFileViewerRootedAtPath:parentDirectoryPath];
}
}
}
return operationStatus;
}for windows : with original comments
bool File::RevealFile() const throw()
{
bool operationStatus = false;
if (!fullPath.isEmpty() && sourceFile.exists())
{
// use the full path to explorer for security
TCHAR winDir[MAX_PATH];
uint32 len = GetSystemDirectory(winDir, MAX_PATH);
// Need enough space to add the trailing backslash!
if (len || !(len > MAX_PATH - 2))
{
winDir[len] = L'\\';
winDir[++len] = L'\0';
juce::String explorerParams;
explorerParams << L"/select,";
explorerParams << (L'\"');
explorerParams << (getFullPathName());
explorerParams << (L'\"');
HINSTANCE result;
if ((result=::ShellExecute(NULL, _T("open"),_T("explorer.exe"), (const TCHAR*)explorerParams,
winDir, SW_SHOWNORMAL)) <= (HINSTANCE) 32)
operationStatus = true;
}
}
return operationStatus;
}P.S. : Justin, will you be kind enough to review it.
Thanx a lot!
It’s always a pleasure.
Just for closure: File::revealToUser
