I'm trying to make a native NSButton object in IB. When I select Accessory as a Button Type, the title disappears. When I try to write the title, the button is not resizing and the triangle keeps disappearing.
How to make a NSButton with text and down-facing accessory triangle on the right indicating this is something you can click and will popover?
Maybe NSPopUpButton is what you're looking for.

I am currently instantiating an NSMatrix w/ NSButtonCell subclasses through IB
I use the identity inspector to change the Tool Tip property
But the tooltip doesn't show on the button cell.
If I set a tooltip on the NSMatrix object, a tooltip still doesn't show
If I add an NSButton to the same view, and add a tooltip to that, it does show
Why won't my tooltips on NSMatrix or NSButtonCell show?
I don't know why it can not be set in the Interface Builder (It seems like a long standing issue), but you can set them at least programmatically.
[self.matrix setToolTip:#"Tooltip for first item" forCell:[self.matrix cellAtRow:0 column:0]];
[self.matrix setToolTip:#"Tooltip for second item" forCell:[self.matrix cellAtRow:1 column:0]];
Careful, if in InterfaceBuilder you click the button, you can add the tooltip to the button, and the class displayed under "Custom Class", top right, is NSButton. But, if you click the button again, as you do while selecting stuff in xcode, what is selected is the NSButtonCell, which appears to have a separate tooltip. If you're not careful you add your tooltip to the NSButtonCell instead of the NSButton, and it won't show in your running application.
So, the problem may be that you have clicked the button one more time in IB, and you thought to enter the tooltip for the NSButton, but you didn't.
Personally I think it may be a bug, why would you want to add a tooltip for the button cell?
I'm making an Cocoa app for Yosemite.
I added a view based NSTableView in Interface builder, but the border 2 pixel width and thicker than Yosemite's Finder's.
And the cell selection color is blue, while Yosemite's Finder's is gray.
And this is how Yosemite's Finder's table view looks like.
I checked the settings in Interface Builder.
The super scroll view of NSTableView's frame setting is (0,0,149,257):
While the Clip View's frame setting is (1, 1, 147, 255) and can not be changed.
And how to make a same NSTableView as Yosemite's Finder's?
Thanks a ton!
The Finder sidebar isn't a table-view it's a Source List NSOutlineView:
The border is applied around the enclosing scroll view:
Note also that a standard NSOutlineView lets you adjust the highlight style from within Interface Buider:
In my experience selected rows are still painted blue, even when the "Source List" highlight style is selected. To avoid that, I needed to prevent the table or outline view from becoming the first responder by subclassing it and adding
- (BOOL)becomeFirstResponder {
return NO;
}
Edit:
Turns out becomeFirstResponder is actually important if you want to support keyboard navigation. I have found a better solution that does not override becomeFirstResponder.
First, create a custom NSTableRowView subclass with an (overridden) empty setEmphasized: method:
- (void)setEmphasized:(BOOL)emphasized {
// This avoids a blue background when selected in a source list that has first responder status.
}
You can then provide an instance of your custom NSTableRowView class by implementing
- (NSTableRowView *)tableView:(NSTableView *)tableView rowViewForRow:(NSInteger)row
in your NSTableViewDelegate.
To whoever wants to remove the NSTableView border...
My requirement was to remove the border colour of the NSTableView so that, it should look like a white box. Tried all properties and forums but couldn't find a way to do that. Finally I came up with a dirty hack in the Storyboard which could fix the problem. If someone have a better option, please let us know.
Embed the NSTableView in a CustomBox. Set the Box BorderType as 'None'
Then set the constraints (Left, Top, Right and Bottom) of NSTableView to the containing Box. Set the values to -2. so that the NSTableView border will be outside of the Box
Now in Storyboard, select the 'clipView(NSClipView)' of the NSTableView. clipView is the superView of the NSTableView
Go to the Size Inspector and uncheck the 'Automatically Adjust' property of the "Content Insets"
Set the values to Left=2, Top=2, Bottom=-2 and Right=-2
Thats it.
I'm trying to make my first Cocoa app (previously I was making iOS apps) and what I wish to do for my custom view is make it's title clickable with indicator (accessory) triangle facing down.
Clicking the title would open a popup/menu with my items.
How is that doneable in Cocoa?
Rdelmar's answer is probably the easiest way to go, but may not do exactly what you might want to do (which is replace the actual title with a pop up item, instead of having a popup button under the title in the toolbar area). With respect to functionality your application will probably work just as well using the toolbar.
If, however, you truly want to replace the actual title, the means of going about this would be to set the NSWindow title text to #"" to hide it, and redraw it by sticking in your own view.
[[[theWindow contentView] superview] addSubview:theSubview];
This basically tells the superview of the main content view to add another subview (direct "translation" from the code), and you'll have to tinker with the frame of this new subview to have it be positioned where the title should be positioned (as now it's free to be placed anywhere in the window frame, including on top of the title bar, as opposed to simply inside the content view).
theSubview can be your popup button, or whatever you want, and you'll also probably have to custom draw the popup button to match the original drawing of the window title.
You can do this by adding a toolbar to your window in IB. Once, you add the toolbar, you can double click on it to open the customizer view of it. Drag a popup button into the Allowable Toolbar Items area and after it is inserted there you can drag it into the bottom area which shows the layout of the toolbar -- you can also drag out any of the default items there that you don't want.
I place a single table view cell on my view using interface builder and add an accessory type, a selection color and enable user interaction.
My problem is that the cell only is highlighted when the user taps on the arrow icon. But it also should be highlighted when the user taps on the text label inside it, he can tap anywhere on the cell.
How can I achieve this?
A UITableViewCell is really only meant to be used within the context of a UITableView (which knows how to handle and/or delegate the selection & highlighting of the cell).
Having a UITableViewCell outside of the context of a table is a somewhat unexpected user interface.
Couldn't you do what you want to do with a UIButton instead?
Or a UIView that has two UIButton subviews (or at least one UIButton subview to contain a widget graphic that looks like the disclosure accessory)? That way the things you want to get highlighted would definitely happen, as opposed to depending on a nonexistent [UITableView didSelectCellAtIndexPath:] method that doesn't exist in a view that isn't a UITableView delegate.
I have an NSWindow with an NSToolbar and a content view.
I have set the tracking area to be the whole frame of the view.
I wish to have the mouseExited event fired when the cursor leaves the content view and enters the toolbar and/or the window title. What is the best way to achieve this? should I bound the tracking area to just below the toolbar?
The main reason I need this is because my view needs a special cursor. So I'm changing it in mouseEntered and wish to change it again when mouseExited
Thanks
Why not add a cursor rectangle over the entire bounds of the view?
