This is OpenPanel,-messages,+such in view mode; [Up]
Date: Sun 11-Sep-1989 19:28:34 From: Unknown Subject: OpenPanel, messages, & such Thanks to the two folks who responded to an earlier message, I now know how to use NXAlert() to put up a little panel requiring a response from the user. It works great. Here's a couple more things. 1. I still want to use the OpenPanel to select a *directory*. I can get the directory if a file is selected, but that is not what I want. By subclassing -text:isEmpty: (see SavePanel) to do nothing but return itself, I keep the OK button enabled, and I subclass +new to manually enable the OK button on startup. The only problem is that hitting the OK button when there is no text on the file name line (i.e. a directory is selected) does nothing but disable the button and nothing more. It doesn't return or set the directory. What I thing I should do is subclass the -ok method (see SavePanel), which is the target of the ok button of the OpenPanel. The only problem is that I don't want to add functionality. I want to *remove* it. If I could subclass it so that it would not check to see if there is a file selected before returning, and would not disable the ok button, that would be wonderful. I don't, however, have the source, and can't figure out what is going on well enough to rewrite everything. I can't use [super ok:sender] because that would do the checking I don't want. I tried to use the delegate (doc'ed in SavePanel) and the method -validateFilename: to unconditionally accept everything, but that didn't work. 2. Can anybody figure out what to do with -setFileFilterFunc: and -fileFilterFunc? They are not documented well, and there is no example. I think the docs for -fileFilterFunc are actually wrong. I found this in <appkit/OpenPanel.h>: typedef (*NXFileFilterFunc)(id self, NXDirEntry *dirEntry) and in <appkit/SavePanel.h>: typedef struct _NXDirEntry { [12 lines of mysterious stuff, including mode & inode deleted] } NXDirEntry; 3. Is there a clever way to display a status (not error) message in a little panel that will pop up on the screen. NXAlert() is fine for error messages or for when I want a response, but is there something that does not require a response from the user, and that I can keep up while the program continues to run, then make go away? | Dan Zerkle home:(805) 968-4683 morning:961-2434 afternoon:687-0110 | | dz@cornu.ucsb.edu dz%cornu@ucsbuxa.bitnet ...ucbvax!hub!cornu!dz | | Snailmail: 6681 Berkshire Terrace #5, Isla Vista, CA 93117 | | Disclaimer: If it's wrong or stupid, pretend I didn't do it. | >From: barry@zaphod.uchicago.edu (Barry Merriman)
