I have a refresh button in an NSToolbarItem and would like to replace the refresh icon with an NSProgressIndicator when there is data loading. Is this possible? Notably, it should still be a button (or at least look like one) but have the progress indicator instead of the button.
I advice you to put progressIndicator in the same place with your button, but with Hidden flag. after you press the button, hide it and show the progress indicator.
for better effect you can use [[button animator] setHidden:YES] but don't forget to make your views layer backed, to make animator works.

I have an NSCollectionView inside a Tab which contains subviews with NSTextField that have expanding tooltips.
Strangely, after a new search (ReloadData) or going to a tab and coming back, the tooltips no longer expand. They come back only if I resize the window or scroll the CollectionView*. Clicking in the view does not help. What can I do to automatically have the tooltips work?
*This triggers the CollectionView and the CollectionViewItems to UpdateTrackingAreas. I tried to force this on ReloadData even delayed 1000 ms, but this did not make the tooltips able to expand.
Thoughts:
Something related to UpdateTrackingAreas but not exactly?
Maybe a first responder issue?
It also doesn't work if the window is not the active window (which is ok)
Concerned that it might be related to How do I update the expansion tooltip size after calling NSTextField setStringValue:?
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 have created a custom (themed) NSWindow, by creating a borderless window and then recreating all elements of the window border/background inside the content view. I've created the window widgets (close box, zoom box, minimize box) on top of my own fake title bar using -standardWindowButton:forStyleMask:.
Trouble is, when a sheet is presented on top of my custom window (e.g. "save changes...", those buttons do not receive the clicks.
Does anybody know how I can tell NSWindow not to intercept the clicks in my minimize box? It works with a standard NSWindow. When a sheet is up, I can still send both of them to the dock, or zoom the window out.
I thought maybe there's special code in the content view that ignores clicks in subviews while a sheet is up. But it seems as if -hitTest: is called on the content view and returns the minimize widget, but the widget's action never gets triggered.
I guess I could just replace the content view and perform the action in the content view's hitTest if it is the minimize widget ... but that seems a bit ugly.
Is there a way to hide the pop-up button of an NSComboBox? I can't find anything in the documentation for NSComboBox or NSComboBoxCell. There is a setButtonBordered: method on NSComboBox, but this just changes to an alterate button style.
If I can't hide it, can I at least disable it?
If the combo box has no items, clicking the pop-up button doesn't do anything.
Maybe you can work around the limitation by emptying the list when you want to disable the button.
It makes clicking have no effect, but it doesn't hide the button or draw it as disabled.
I don't think this is possible. An NSComboBox without the button is effectively an NSTextField, so I guess it was deemed unnecessary. You could probably do this by subclassing NSComboBoxCell and override -drawWithFrame:inView: or -drawInteriorWithFrame:inView:.
Safest way would probably be to add your own buttonHidden property and use the ObjC runtime method class_getMethodImplementation to look up the IMP for the same method in NSTextField and just call that when the button is hidden. You'd effectively be calling super's super, so you'd get a regular text field look.
you can disable it by doing:
myComboBox.Enabled = false;
I've created a custom subclass of NSCell with an NSImageCell, some NSTextFieldCells, and an NSPopUpButtonCell.
I'm initializing the pop up cell using:
myPopUpCell = [[NSPopUpButtonCell alloc] init];
[myPopUpCell setBordered:NO];
[myPopUpCell setAutoenablesItems:NO];
[myPopUpCell addItemsWithTitles:[NSArray arrayWithObjects:#"Item1", #"Item2", #"Item3"]];
And drawing it in drawInteriorWithFrame:inView:
Everything seems to work great, except that when clicking on the pop up cell while running my app the cell does not pop up. Any suggestions about what might be wrong?
Drawing the pop-up button cell in drawInteriorWithFrame:inView: is going to do just that; draw it, but nothing else. Handling click events is unrelated to drawing, so you're going to have to do some work in your custom cell to interpret mouse events, and if they're inside the frame you're using for the pop-up button, pass them on to the button cell. Start by subclassing the methods listed in the NSCell docs under tracking the mouse, such as –trackMouse:inRect:ofView:untilMouseUp:, and you should be be able to figure out what's needed to make the button cell act correctly.
Depending on what you're doing you may actually find it easier to draw the title string yourself, and just use NSMenu's +popUpContextMenu:withEvent:forView:.
