How to display a message to the user from script-fu

[Ofnuts]

With this code:

Code:

pdb.gimp_message_set_handler(MESSAGE_BOX)
pdb.gimp_message("Hello in status bar") # Single line, goes to status bar
pdb.gimp_message("Hello\nin dialog")    # Multi-line, goes to dialog
pdb.gimp_message("Hello in dialog again") # Single line, goes to dialog which is out
pdb.gimp_message_set_handler(ERROR_CONSOLE)
pdb.gimp_message("Hello in Gimp message console")
pdb.gimp_message_set_handler(CONSOLE)
pdb.gimp_message("Hello in stdout/stderr of Gimp process")

I get this:

   

That draws the following remarks for MESSAGE_BOX

• If the message is a single line, and the message dialog is not out, the message goes to the status bar.
  
• If the message is multi-line, a dialog is shown
  
• If the multi-line dialog is out, other messages are added to it
  

Your problem is possibly that the dialog is either masked or off-screen.
