I have defined a FilenameCustomGui to get the image filename.
Then I drag & drop a image to the field.

    BaseContainer settings;
    settings.SetBool(FILENAME_TEXTURE, true);	
    myHdrfile = (FilenameCustomGui* )AddCustomGui(1009, CUSTOMGUI_FILENAME, "", BFH_SCALEFIT, 0, 0, settings);

Then in the message part, I get the id and try to get the filename, but it is always empty?
The first part show how it is done in python (and working).
Also how to put the filename back into the FilenameCustomGui field?

Int32 MainDialog::Message(const BaseContainer& msg, BaseContainer& result)
{
  
  // working python code
    //    def Message(self, msg, result) :             #get filename drag&drop to MY_HDRFILE field
    //
    //    #print "Message id: ", msg.GetId()
    //    if (msg.GetId() == c4d.BFM_ACTION) :
    //        cid = msg[c4d.BFM_ACTION_ID]
    //        val = msg[c4d.BFM_ACTION_VALUE]
    //        #print 'Msg ID:', cid, ' Val:', val
    //        if (cid == MY_HDRFILE) : self.SetString(cid, val)
    //    return gui.GeDialog.Message(self, msg, result) 
  
	switch (msg.GetId())
	{
		case BFM_ACTION:
			Int32 actionId = msg.GetInt32(BFM_ACTION_ID);
  
			//BaseContainer    action(BFM_ACTION);
			//String val = msg(action).GetString(BFM_ACTION_VALUE);
  
			String val = msg.GetString(1009, "ABC");
			GePrint ("Action ID + value: " + String::IntToString(actionId) + " - " + val);
  
			break;
	}
	return GeDialog::Message(msg, result);
}

Hi Pim,

your C++ code does not equal your Python code in its semantics.

Though, I don't understand why you would want to do that? The message is triggered when
the value of the field changes, you don't have to update the value of the field using SetString()
by yourself.

Best,

Hi Niklas,

Sorry, I think I was not clear enough.
Because I drag a hdri file from a lib to the GUI field, it is not recognized by the FilenameCustomGui.
Only when you select a file by using file selection button you get the filename using the FilenameCustomGui. So not when using drag & drop.
That is why I use MainDialog::Message to get the value. MainDialog::Message recognizes drag&drop and returns the filename. 
At least it does in python. In c++ I always get an empty filename?

Here the complete code.

  
#include "c4d.h"

	virtual Bool Command(Int32 id, const BaseContainer& msg);
	virtual Int32 Message(const BaseContainer& msg, BaseContainer& result);
};

    settings.SetBool(FILENAME_TEXTURE, true);	
    myHdrfile = (FilenameCustomGui* )AddCustomGui(1009, CUSTOMGUI_FILENAME, "", BFH_SCALEFIT, 0, 0, settings);
	GroupEnd();
	return true;
}

}

{

	{

		{
			Filename fn;
			String hdrName;
			fn = myHdrfile->GetData().GetValue().GetFilename();
  
			hdrName = fn.GetFileString();
			GePrint ("Given file: " + hdrName);
			break;
		}
  
	}
	return true;
}
  
Int32 MainDialog::Message(const BaseContainer& msg, BaseContainer& result)
{
	switch (msg.GetId())
	{
		case BFM_ACTION:
  
			if (msg.GetInt32(BFM_ACTION_ID) == 1009)	//Give hdri link when drag&drop is used!
			{
				String val = msg.GetString(BFM_ACTION_VALUE);	//always returns empty

The data in your customgui gizmo is a Filename type of data.
So when you request the BFM_ACTION_VALUE in your Message() method. You have to request a Filename type...Not a String type.
That's why it's not  returning anything.

Once you have the Filename value. Then you can convert it to a string value
Give this code a try in your Message() method:

    if(msg.GetId() == BFM_ACTION)   
  {  
      Filename fn = msg.GetFilename(BFM_ACTION_VALUE);  
      String hdrName = fn.GetFileString();  
      GePrint(hdrName);       
  }

Yes, great, thanks a lot.
I am beginning to like c++, although there is still a lot to learn.
