I am using the following to create an NSPopupButton programmatically:
...
NSPopUpButton *accessoryView = [[NSPopUpButton alloc] initWithFrame:NSMakeRect(0, 0, 100, 24) pullsDown:YES];
NSFont *aFont = [NSFont systemFontOfSize:[NSFont systemFontSizeForControlSize:NSSmallControlSize]];
[accessoryView setBezelStyle:NSRecessedBezelStyle];
[accessoryView setFont:aFont];
[accessoryView setShowsBorderOnlyWhileMouseInside:YES];
[accessoryView setAutoresizingMask:NSViewMaxXMargin | NSViewMinYMargin];
NSArray *popupItems = [[NSArray alloc] initWithObjects:#"Your Account", #"Sign In", #"Create Account", nil];
[accessoryView addItemsWithTitles:popupItems];
...
Now, when I add the NSPopUpButton to my view, I end up with the button's text overlapping the icon used for the dropdown menu. I have seen this previously when I use NSControl:setAlignment but I am not using this here. Here is the output:
Can anyone see what I'm doing wrong?
Take care,
Jeremy
It just so happens this is a simple fix. (Thanks Beelsebob on irc.freenode.net!) Basically, you need to have the following code:
[[accessoryView cell] setArrowPosition:NSPopUpArrowAtBottom];
in there somewhere. (I added it just below the line to add the menu items.) I had read the API docs on this call a few times before, since I had implemented the same call with a value of NSPopUpNoArrow to remove the arrow as an interim fix, but it didn't make it clear that the proper value being used above would do what it's doing. Problem solved.

I want to display tooltips over parts of an attributed string, and thought that using an NSToolTipAttributeName attribute on the required ranges would do the trick but I can't get it to work.
I am trying in MACOS, Xcode (9.2)
NSString *fullString = #"Create a new tooltip";
NSString *compareString =#"tooltip";
NSRange tooltipRange = [fullString rangeOfString: compareString];
[senderTextView.textStorage addAttribute:NSToolTipAttributeName
value:#"Custom tooltip"
range:tooltipRange];
[senderTextView.textStorage addAttribute:NSForegroundColorAttributeName
value:[NSColor redColor] range:tooltipRange];
The word "tooltip" is shown in red as expected, but no tooltip appears when I hover over it. What am I missing?
Couple of ways to do this, using the NSToolTipAttributeName in combination with NSLinkAttributeName, e.g.:
NSMutableDictionary* labelAttributes = [NSMutableDictionary new];
labelAttributes[NSToolTipAttributeName] = #"Tooltip";
labelAttributes[NSLinkAttributeName] = #"Link";
NSAttributedString* labelString = [NSAttributedString
attributedString:#"Display"]
withAttributes:labelAttributes];
Being careful not to forget displaysLinkToolTips = YES on the NSTextView.
Alternately, you can use the NSView Tooltips API, which provides:
- (NSToolTipTag)addToolTipRect:(NSRect)rect owner:(id)owner userData:(void *)data;
It seems that NSButtonCell's setFont method is not available anymore from 10.9.
Is there any way (or category) to (re)implement it?
I don't know why Apple forces it's own styles on buttons.
I am trying for 2 days to style my own custom button (I also needed a category to simply change the button's text color - shame).
You can use -setAttributedTitle: of NSButton to set the style of button title.
Sample code:
NSDictionary *attributes = #{NSForegroundColorAttributeName: [NSColor redColor], NSFontAttributeName: [NSFont userFixedPitchFontOfSize:13.0f]};
NSAttributedString *aString = [[NSAttributedString alloc] initWithString:#"Button" attributes:attributes];
[button setAttributedTitle:aString];
In my app for Mac I have a webview that shows some html content. I create a PDFDocument from that webview and then I want to print that document. So I create a PDFView from the document and then I call the NSPrintOperation printOperationWithView. When showing the print panel all appears correct except the page preview which appears blank, but if I press the details button the panel is refreshed and the page preview appears correctly.
How can I solve this??
Need help please. Thanks in advance.
This is an example of my problem:
1- The print panel shows with a blank page preview. Next I press show details.
2- After refreshing the panel the page preview appears correctly.
This is my code:
NSPrintInfo *printInfo = [NSPrintInfo sharedPrintInfo];
[printInfo setTopMargin:0.0];
[printInfo setBottomMargin:0.0];
[printInfo setLeftMargin:0.0];
[printInfo setRightMargin:0.0];
[printInfo setHorizontalPagination:NSFitPagination];
[printInfo setVerticalPagination:NSAutoPagination];
[printInfo setVerticallyCentered:NO];
[printInfo setHorizontallyCentered:YES];
NSData *pdfFinal = [[[[webView mainFrame] frameView] documentView] dataWithPDFInsideRect:[[[webView mainFrame] frameView] documentView].frame];
PDFDocument *doc = [[PDFDocument alloc] initWithData:pdfFinal];
PDFView *pdfView = [[PDFView alloc] init];
[pdfView setDocument:doc];
NSPrintOperation *op;
op = [NSPrintOperation printOperationWithView:pdfView.documentView printInfo:printInfo];
[op setShowsProgressPanel:YES];
[op setShowsPrintPanel:YES];
[op runOperation];
From this link:
PDFDocument *doc = ...;
// Invoke private method.
// NOTE: Use NSInvocation because one argument is a BOOL type. Alternately, you could declare the method in a category and just call it.
BOOL autoRotate = NO; // Set accordingly.
NSMethodSignature *signature = [PDFDocument instanceMethodSignatureForSelector:#selector(getPrintOperationForPrintInfo:autoRotate:)];
NSInvocation *invocation = [NSInvocation invocationWithMethodSignature:signature];
[invocation setSelector:#selector(getPrintOperationForPrintInfo:autoRotate:)];
[invocation setArgument:&printInfo atIndex:2];
[invocation setArgument:&autoRotate atIndex:3];
[invocation invokeWithTarget:doc];
// Grab the returned print operation.
void *result;
[invocation getReturnValue:&result];
NSPrintOperation *op = (__bridge NSPrintOperation *)result;
[op setShowsPrintPanel:YES];
[op setShowsProgressPanel:YES];
[op runOperation];
This works on OSX from 10.4 to 10.10 (Yosemite).
EDIT: You can also see this answer which is similar, but with less lines of code.
At a guess, since PDFView is a subclass of NSView, whose designated initializer is -initWithFrame:, not -init, your call to PDFView *pdfView = [[PDFView alloc] init] may not be allowing the PDFView to set up its initial state, though subsequent calls to its machinery may be magically resolving this state for you but NSView and subclasses tend to behave strangely (particularly with respect to drawing) when you don't use the proper designated initializer (which means its frame and bounds are equal to NSZeroRect).
Try using -initWithFrame: with some reasonable, non-zero rectangle.
Update
Alright, just a wild shot in the dark, but the documentation for NSPrintOperation says that -runOperation blocks the main thread and recommends using -runOperationModalForWindow:delegate:didRunSelector:contextInfo: to avoid blocking the main thread entirely. Is it possible that by blocking the main thread something else is being prevented from doing its initial work (I'd call this either undocumented behavior or an API bug, but...)? Try implementing the modal version instead and see if that helps. If not, I'd actually file a bug report with Apple.
I have a basic NSRecessedBezelStyle NSButton added via IB to an NSView. Why is the font messed up in its unselected state? Is this normal?
As you can see, when pushed the recessed button looks fine, but unpressed it's solid black with no shadow. Am I missing something really obvious somewhere? I tried messing around with setAttributedTitle and setAttributedAlternateTitle but that yielded odd results with the push on push off mechanic.
That is the expected behavior for NSRecessedBezelStyle with the default "Push On Push Off" Type, bezeled in On state, plain text in OFF, additionally you can change the Type so the bezel is only displayed when hovering, here is the code to make it gray.
NSMutableDictionary *attrsDictionary = [NSMutableDictionary dictionaryWithCapacity:1];
[attrsDictionary setObject:[NSColor grayColor] forKey:NSForegroundColorAttributeName];
[attrsDictionary setObject:[NSFont boldSystemFontOfSize:12.0] forKey:NSFontAttributeName];
NSMutableParagraphStyle *paragraph = [[[NSMutableParagraphStyle alloc] init] autorelease];
[paragraph setAlignment:NSCenterTextAlignment];
[attrsDictionary setObject:paragraph forKey:NSParagraphStyleAttributeName];
NSAttributedString *str = [[[NSAttributedString alloc] initWithString:#"Button" attributes:attrsDictionary] autorelease];
[button setAttributedTitle:str];
I added programmatically NSTextField to my NSView:
NSTextField *projectLabel = [[NSTextField alloc] initWithFrame:frame];
[projectLabel setStringValue:#"projectName"];
[projectLabel setBezeled:NO];
[projectLabel setDrawsBackground:NO];
[projectLabel setEditable:NO];
[projectLabel setSelectable:NO];
[projectLabel setFont:[NSFont controlContentFontOfSize:13]];
projectLabel.autoresizingMask = NSViewMaxXMargin | NSViewMinYMargin;
[self addSubview:projectLabel];
[self setAutoresizesSubviews:NO];
This field was added correctly, but when I change size of view (or even move window to second display), font on field changes very weird (see attached image).
on start
after change of the size
I do not know what I did wrong
I drew this label on drawRect every time, when the size changes.
So, you're manually telling the field to display in its parent view's drawRect:?
Don't do that. It's a subview, so it'll get told to draw in its turn anyway. Just let that happen.
