HI,
I've just had a look at the new DIALOG2 stuff. Very nice ;)
Here comes a suggestion to allow the user to display the alert as
sheet bound to the current document window:
If option -e or 'sheet' is given it shows the alert as sheet.
CODE:
##########################################################################
#import "../Dialog2.h"
#import "../TMDCommand.h"
#import "../OptionParser.h"
/*
echo '{alertStyle = warning; buttonTitles = ('OK'); messageTitle =
'test'; informativeText = 'Testing';}' | "$DIALOG" alert
"$DIALOG" help alert
"$DIALOG" alert -s critical -m "FOOL!" -t "test" -1 foo -2 bar -3 baz
"$DIALOG" alert -e -s critical -m "FOOL!" -t "test" -1 foo -2 bar -3 baz
*/
// =========
// = Alert =
// =========
@interface TMDAlertCommand : TMDCommand
{
}
@end
@implementation TMDAlertCommand
int sheetReturn;
+ (void)load
{
[super registerObject:[self new] forCommand:@"alert"];
}
static option_t const expectedOptions[] =
{
{ "m", "message", option_t::required_argument,
option_t::string, "Message title."},
{ "t", "text", option_t::required_argument,
option_t::string, "Informative text for the alert."},
{ "s", "alert-style", option_t::required_argument,
option_t::string, "One of warning, critical or informational (the
default)."},
{ "1", "button1", option_t::required_argument,
option_t::string, "Button 1 label."},
{ "2", "button2", option_t::required_argument,
option_t::string, "Button 2 label."},
{ "3", "button3", option_t::required_argument,
option_t::string, "Button 3 label."},
{ "e", "sheet", option_t::no_argument, option_t::none, "If given
displays alert as sheet."},
};
- (void)handleCommand:(CLIProxy*)proxy
{
// NSFileHandle* fh = [options objectForKey:@"stderr"];
SetOptionTemplate(proxy, expectedOptions);
NSAlertStyle alertStyle = NSInformationalAlertStyle;
NSString *alertStyleString = [proxy
valueForOption:@"alert-style"];
NSDictionary *resultDict = nil;
NSAlert *alert = [[[NSAlert alloc] init] autorelease];
int offset = 0;
if([alertStyleString isEqualToString:@"warning"])
{
alertStyle = NSWarningAlertStyle;
}
else if([alertStyleString isEqualToString:@"critical"])
{
alertStyle = NSCriticalAlertStyle;
}
else if([alertStyleString isEqualToString:@"informational"])
{
alertStyle = NSInformationalAlertStyle;
}
[alert setAlertStyle:alertStyle];
if([proxy valueForOption:@"message"])
[alert setMessageText:[proxy valueForOption:@"message"]];
if([proxy valueForOption:@"text"])
[alert setInformativeText:[proxy valueForOption:@"text"]];
// Setup buttons
offset = NSAlertFirstButtonReturn;
if ([proxy valueForOption:@"button1"])
[alert addButtonWithTitle:[proxy valueForOption:@"button1"]];
if ([proxy valueForOption:@"button2"])
[alert addButtonWithTitle:[proxy valueForOption:@"button2"]];
if ([proxy valueForOption:@"button3"])
[alert addButtonWithTitle:[proxy valueForOption:@"button3"]];
BOOL modal = YES;
if([proxy valueForOption:@"sheet"])
modal = NO;
// Show the alert
if(modal)
{
int alertResult = ([alert runModal] - NSAlertFirstButtonReturn);
resultDict = [NSDictionary dictionaryWithObject:[NSNumber
numberWithInt:alertResult] forKey:@"buttonClicked"];
[TMDCommand writePropertyList:[NSString
stringWithFormat:@"%d",sheetReturn - offset] toFileHandle:[proxy
outputHandle]];
}
else
{
id documentWindow =nil;
enumerate([NSApp windows], id item)
if([item isKindOfClass:NSClassFromString(@"NSWindow")])
if([item isKeyWindow])
documentWindow = item;
sheetReturn = -1;
[alert beginSheetModalForWindow:documentWindow
modalDelegate:self
didEndSelector:@selector(mySheetDidEnd:returnCode:contextInfo:)
contextInfo:NULL];
[NSApp runModalForWindow:[alert window]];
[TMDCommand writePropertyList:[NSString
stringWithFormat:@"%d",sheetReturn - offset] toFileHandle:[proxy
outputHandle]];
}
}
-(id)mySheetDidEnd:(NSWindow *)sheet returnCode:(int)returnCode
contextInfo:(void *)contextInfo
{
[NSApp endSheet:sheet];
sheetReturn = returnCode;
[NSApp stopModal];
return nil;
}
- (NSString *)commandDescription
{
return @"Show an alert box.";
}
- (NSString *)usageForInvocation:(NSString *)invocation;
{
return [NSString stringWithFormat:@"%@ «options»\n\nOptions:\n%@",
invocation, GetOptionList(expectedOptions)];
}
@end

Any comments?
On the other hand, this doesn't work for me:
echo '{alertStyle = warning; buttonTitles = ('OK'); messageTitle =
'test'; informativeText = 'Testing';}' | "$DIALOG" alert
(?)
Cheers,
