If my understanding is correct, there are two types of content that can be copied to the Mac global (systemwide) clipboard:
Even though they are two different, discrete data types, they share the very same clipboard. For example, if you have an image
file on your clipboard, and then you copy a
text sentence, the sentence will overwrite the image file, and vice versa. Please correct me if I am wrong.
My question is, how can I determine if the clipboard does not contain
text, using AppleScript?
The context of my question is an AppleScript .scpt file that speaks the selected text in the System Voice at a specified volume. The selected text is copied to the clipboard, and then the text is spoken via the
say command. The script is triggered by keystroke via FastScripts.app.
Every so often, I am given an error dialog that states, "Error Number: -1728." This error occurs when, instead of
text being highlighted, I have highlighted or selected an actual
file. Mac's Speech function cannot speak a
file; Speech can only verbalize
So, I would like to create an
if...then statement in my script to catch this error. Ideally, I would then like to convert the
text, if possible in the way that TextEdit does.
