hey all,
i've read an article (cocoa-java) on making the dock bouncing :
<http://www.onjava.com/pub/a/onjava/2005/08/10/swinghacks.html?page=1>
the author wrote (under Bounce the Mac OS X Dock Icon) :
The com.apple.cocoa.application package contains an NSApplication
object that has lots of useful methods. In particular, you want the
requestUserAttention() method, which will make the dock icon bounce.
import com.apple.cocoa.application.*;
// ...
public void bounceDock() {
NSApplication app = NSApplication.sharedApplication();
int id = app.requestUserAttention(
NSApplication.UserAttentionRequestCritical);
}
// ...
NSApplication has a static method to get the singleton that
represents the application. You can then call the
requestUserAttention() method with the constant
NSApplication.UserAttentionRequestCritical to make the dock bounce
continuously. You can use other constants for other behaviors. The
return value can be passed to the cancelUserAttentionRequest()
method to cancel the alert once the user has responded. Be sure to
add the /System/Library/Java/ directory to your classpath when
compiling, so that javac will find the Cocoa wrapper classes.
then i've tested that (in Cocoa-Ruby) :
def bounce_dock
app=OSX::NSApplication.sharedApplication
# p "app.class=#{app.class}" here i get the right class !!!
# p "OSX::NSApplication.UserAttentionRequestCritical=#
{OSX::NSApplication.UserAttentionRequestCritical}"
# NSApplication#UserAttentionRequestCritical - methodSignature is nil
#id = app.requestUserAttention
(OSX::NSApplication.UserAttentionRequestCritical)
#NSApplication#UserAttentionRequestCritical - methodSignature is nil
# id = app.requestUserAttention
(OSX::NSApplication.UserAttentionRequestCritical)
end
and if i call onto AppKiDo NSApplication doesn't have such methods.
what are the correct methods and constants.
or, may be, i'm doing that wrongly ?
best
Yvon
