Folks;
I want to open a small 'splash screen' during my application's
startup phase.
In my NSApp delegate's -awakeFromNib I open an NSPanel with a simple
textField.
Depending on the user's configuration there maybe quite a lot of
tasks to accomplish during the launch phase...
I would like to update the text with information as I proceed thru
the launch process.
I have tried several approaches and they all suffer from the same
issue: the textField does not always display the updated information.
I have set an outlet to the textField and bound the 'value' to a KVC
compliant string.
I call the string's set method -> sometimes nothing happens
I call set and then the textfields's setNeedsDisplay -> sometimes
nothing happens
I also tried binding the text field to a user default which I then
updated at various times - again not always displayed...
I also tried sending the panel an -update message...
I've also tried spawning a thread for the updating of the text field
- same result.
The launch process is modestly complex so it gives me pause to try
and 'thread' it.
Things need to happen in a particular order, one thing following the
other...
Besides busting the launch process apart or spawning it off on a
thread and then implementing NSMachPorts seems like a lot of work to
just get a string drawn...
Or maybe that's what really have to do....
I realize I'm creating a tension between trying to launch as quickly
as possible and keeping the user informed.
Any thoughts on how I can just 'force a redraw' on this textField?
Thank-you for your time and consideration,
Steve
