Hi all,
I'm trying to build a simple Cocoa GUI that acts as an observer to my
Ruby text application and reports progress in a window (with a
progress bar, etc).
I'm using RubyCocoa for creating the GUI, but I guess anyone who does
not know Ruby or RubyCocoa might be still able to answer my question.
My problem is that I need to run the following GUI in a separate
thread and be able to send messages to it from my main app.
Can anyone point how to do this? I've tried wrapping the app
instantiation in a NSObject and doing
NSThread.detachNewThreadSelector_toTarget_withObject(:run, runner,
nil) to it, but the window does not appear.
Thanks.
--------------------------------
require 'osx/cocoa'
include OSX
class AppDelegate < NSObject
def init
frame = [200.0, 300.0, 250.0, 100.0]
@win =
NSWindow.alloc.initWithContentRect_styleMask_backing_defer(frame,
15, 2, 0)
@win.setTitle 'Test'
@win.setLevel 0
@bar = NSProgressIndicator.alloc.initWithFrame [10.0, 10.0, 80.0,
80.0]
@win.contentView.addSubview(@bar)
@bar.setIndeterminate(false)
@win.display
@win.orderFrontRegardless
end
def step
@bar.incrementBy(20)
end
end
app = NSApplication.sharedApplication
app.setDelegate(AppDelegate.alloc.init)
app.run
