[Cocoapsql-developer] commit; queryView and Submit button behavior; window title

[Olaf v. O. <ol...@ad...>]

- By replacing the queryScrollView's NSTextView with my subclass 
PSQLTextView, I enabled the use of the (queryScrollView-) NSTextView's 
becomeFirstResponder and resignFirstResponder for the purpous of 
registering when the View becoms and resings FirstResponder. With these 
'notifications' I am able to set and reset the commitButton's 
keyequivalent properly so that the commitButton looks like the default 
button only when the view is FirstResponder. To have the submitButton 
actually act on RETURN or ENTER when the queryView is FirstResponder we 
need to send the button a performClick from within the - 
(void)textDidEndEditing:(NSNotification *)aNotification.

=> Modified the MainMenu.nib: Submitt button now has no keyequivalent 
(when first displaying the window)
=> Added PSQTextView to the project
=> Added to PSQLController.m #import "PSQLTextView.h"
=> Added to PSQLControler:
/* gets invoked by the custom subclass PSQLTextView
Therefore this file needs to be the delegate of the View */
-(void)psqlTextViewDidBecomeFirstResponder:(id)sender {
	if (sender == querySpace) [submitButton setKeyEquivalent:@"\r"];
}

/* gets invoked by the custom subclass PSQLTextView
Therefore this file needs to be the delegate of the View */
-(void)psqlTextViewDidResignFirstResponder:(id)sender {
	if (sender == querySpace) [submitButton setKeyEquivalent:@""];
}
Added to the beginning of the -(void)awakeFromNib
	/* replacing the querySpace ScrollView's TextView with an instance 
of PSQLTextView to receive  psqlTextViewDidBecomeFirstResponder and 
psqlTextViewDidResignFirstResponder messages */
	id queryScrollView = [querySpace enclosingScrollView];
     	NSSize queryScrollViewSize = [queryScrollView contentSize];
	// replace NSScrollView's NSTextView with MyTextView
	querySpace = [[PSQLTextView alloc] initWithFrame:NSMakeRect(0,0, 
queryScrollViewSize.width, queryScrollViewSize.height)];
	[querySpace setMinSize:NSMakeSize(0.0,queryScrollViewSize.height)];
	[querySpace setMaxSize:NSMakeSize(1e7,1e7)];
	[querySpace setVerticallyResizable:YES];
	[querySpace setHorizontallyResizable:NO];
	[querySpace setAutoresizingMask:NSViewWidthSizable];
	[queryScrollView setDocumentView:querySpace];
	[querySpace release];					// as theScrollView retains the TextView
	[querySpace setDelegate:[mainWindow delegate]];	// restore the 
delegate connection
	/* end of replacing the querySpace TextView */

=> Added to PSQLController
- (void)textDidEndEditing:(NSNotification *)aNotification{
	/* the querySpace TextView does end editing on RETURN or ENTER 
while (in awakeFromNib)
	   the view's FieldEditor is set to YES ([querySpace 
setFieldEditor:YES])*/
     NSEvent *event = [NSApp currentEvent];
     if( [aNotification object]== querySpace ){
		//fire the Window's default button's action on RETURN or ENTER
         if ( ([event keyCode] == 36 |[event keyCode] == 76) || [event 
type] == NSKeyUp) {
			[submitButton performClick:self];
			// stay in the TextView for new queries to enter and execute:
			[mainWindow makeFirstResponder:querySpace];
		}
     }
