Starting with Mac OS X 10.7, new NSDocument windows as well as alert windows open with an animation. Windows opened with NSWindowController's showWindow: method, however, get no animation.
Is there a way for these windows to get the same animation?
You can define how a window opens.
In the Interface Inspector under Animation you can choose Document Window Style, and you should get the same behaviour.
Or in code:
[self.window setAnimationBehavior:NSWindowAnimationBehaviorDocumentWindow];
Here all the behaviours you can use
enum {
NSWindowAnimationBehaviorDefault = 0, // let AppKit infer animation behavior for this window
NSWindowAnimationBehaviorNone = 2, // suppress inferred animations (don't animate)
NSWindowAnimationBehaviorDocumentWindow = 3,
NSWindowAnimationBehaviorUtilityWindow = 4,
NSWindowAnimationBehaviorAlertPanel = 5
};

I’m not sure if I am referring to this correctly, but when I use the word “UnMaximize”, I’m referring to:
When you click on the green button which is third on the top left of a
Chrome Window, it Maximizes the Window. When I use the word
“UnMaximize” above, I’m referring to the behavior that clicks that
button again so that it is no longer in full screen.
(By the way, what is the correct word for this in MacOS Terminology?)
I enjoy using the Easy Move+Resize App. While it can move Windows around, unfortunately, it has no effect on windows that are Maximized. Fortunately, the code is available on Github.
I’m curious if anyone can point me how to UnMaximize a Window using the Accessibility API
Does anyone what is the UnMaximize equivalent to kAXCloseButtonAttribute
I’m using MacOs 10.12 if that helps.
I’m grateful to #Willeke - Willeke for pointing me in the correct direction.
As mentioned in my question, I was looking at the code of the Easy Move+Resize App on GitHub. The problem with this code/app is that it does not work for Windows that are currently Maximized i.e. it tries to move these Windows, but it cannot, because they are fixed. (Note: This only has use and is relevant in a multi-monitor setup.) This app works correctly for Windows that are not Maximized.
Here, I am trying to add code that would UnMaximize a window in order to move it, and then Maximize it again after it has been moved. Obviously, the code below is in the context of this app, but I’m sure would be useful to users in other contexts.
I first added a wasMaximized property to EMRMoveResize.h
//EMRMoveResize.h
#property bool wasMaximized;
Next, I moved to EMRAppDelegate.m where the actual Event Callback code is. It should be noted that we are only concerned with moving i.e. only concerned with the Left Mouse Button. (This app uses the Right Mouse Button for resizing, which is not relavent when the Window has been maximized.) So, we are only concerned with kCGEventLeftMouseDown, kCGEventLeftMouseDragged and finally with kCGEventLeftMouseUp. In pseudo code, I have done something like:
If (LeftMouseDown) {
Find out if Window is Maximized
If (Window is Maximized) {
set the wasMaximized property
Click FullScreen Button to UnMaximize the Window in Order to Move it
}
The Window is now UnMaximized would now move as other windows in the LeftMouseDragged event, which I have not made any changes to. Finally,
If(LeftMouseUp) {
If(wasMaximized value was set) {
Click FullScreen Button again to Maximize the Window (Since it started out as Maximized)
Reset the wasMaximized property
}
}
Now for the snippets of code changes to EMRAppDelegate.m
if (type == kCGEventLeftMouseDown
|| type == kCGEventRightMouseDown) {
//..
//Skipped Unchanged Code
//..
//Find out if Window is Maximized
CFTypeRef TypeRef = nil;
if (AXUIElementCopyAttributeValue((AXUIElementRef)_clickedWindow, CFSTR("AXFullScreen"), &TypeRef)) {
if(Debug) NSLog(#"Could not get wasMaximized Value");
} else {
[moveResize setWasMaximized: CFBooleanGetValue(TypeRef)];
if(Debug) NSLog(CFBooleanGetValue(TypeRef) ? #"Updated Maximized to True" : #"Updated Maximized to False");
}
//Click FullScreen Button to UnMaximize the Window in Order to Move it
if([moveResize wasMaximized]) {
AXUIElementRef buttonRef = nil;
AXUIElementCopyAttributeValue(_clickedWindow, kAXFullScreenButtonAttribute, (CFTypeRef*)&buttonRef);
if(Debug) NSLog(#"buttonRef: %p", buttonRef);
AXUIElementPerformAction(buttonRef, kAXPressAction);
CFRelease(buttonRef);
}
//..
//Skipped Unchanged Code
//..
}
if (type == kCGEventLeftMouseUp
|| type == kCGEventRightMouseUp) {
//..
//Skipped Unchanged Code
//..
//Click FullScreen Button again to Maximize the Window (Since it started out as Maximized)
AXUIElementRef _clickedWindow = [moveResize window];
if([moveResize wasMaximized]) {
AXUIElementRef buttonRef = nil;
AXUIElementCopyAttributeValue(_clickedWindow, kAXFullScreenButtonAttribute, (CFTypeRef*)&buttonRef);
if(Debug) NSLog(#"buttonRef: %p", buttonRef);
AXUIElementPerformAction(buttonRef, kAXPressAction);
CFRelease(buttonRef);
[moveResize setWasMaximized: false];
}
//..
//Skipped Unchanged Code
//..
}
This worked for me. But I'm not an expert in Objective C or MacOS, so if you feel something can be improved, feel free to edit this post.
I had the need to create a window so it covers the menubar at top and the dock at bottom. So I had to [NSWindow setLevel:NSMainMenuWindowLevel+1] (if i did just NSMainMenuWindowLevel some of the corner items in the top right of the menubar would still show over my window so I had to go +1).
So now the issue is, a user right clicks in my window (which is a canvas drawing of an image) and then they select "save as", at this point I pop open the "Save as" dialog, but it is showing behind my window. Is there anyway to like find that just opened dialog window with objc and set its level to be above NSMainMenuWindowLevel+1?
Like is there anyway to make this panel open higher then this level:
var NSSavePanel = objc_getClass('NSSavePanel');
var savePanel = sel_registerName('savePanel');
var aSavePanel = objc_msgSend(NSSavePanel, savePanel);
var runModal = sel_registerName('runModal')
Thanks
You have to defer the setting of the save panel's level until after the window is showing, which is tricky. You can do something like this (in Objective-C) before the call to -runModal:
dispatch_async(dispatch_get_main_queue(), ^{
[[NSApp modalWindow] setLevel:NSMainMenuWindowLevel+1];
});
If you can't use GCD, you can use -performSelector:withObject:afterDelay: with a 0 delay. You'll have to use the selector of a method of your own. (You can't use #selector(setLevel:) because that takes a scalar, not an object, as its parameter.)
I've got an application that runs at startup as a menu in the OS X menu bar (i.e., as a background application). When you select an option from the menu, it transforms into a foreground application (creating a dock icon) and shows a window.
Here's the background/foreground code I'm using:
+(void) TransformToForegroundApplication {
ProcessSerialNumber psn = { 0, kCurrentProcess };
TransformProcessType(&psn, kProcessTransformToForegroundApplication);
}
+(void) TransformToBackgroundApplication {
ProcessSerialNumber psn = { 0, kCurrentProcess };
TransformProcessType(&psn, kProcessTransformToUIElementApplication);
}
Pretty standard stuff, from the looks of things. And it works fine, except for one small issue.
The problem is that after I call TransformToForegroundApplication, I call makeKeyAndOrderFront: on the window to make it come to the front of the Z-order and receive focus - but it does neither. It shows up in the background, underneath everything else. I need to either click on the dock icon, or minimize all of the windows in front of it and then click on that window, in order to bring it to the front.
Any ideas?
Probably you need to activate the application, which I presume TransformProcessType() will not do automatically, and know -makeKeyAndOrderFront: will not.
Have you tried calling [NSApp activateIgnoringOtherApps:YES]?
My application has a WinJS AppBar control at the bottom of the screen. I use .showOnlyCommands(buttonsToShowArray) to show and hide buttons on ListView itemSelectionChanged event.
The problem I have right now is that when every I call .showOnlyCommands, the buttons to be hidden (or you may say "replaced") are going to flash on the top of the screen.
I tried to use the Microsoft sample app, this doesn't happen. I tried to use .showCommands + .hideCommands method, it is the same behavior. Note that this didn't happen before the Release Preview version of Win8.
I have no idea what is going on. Any idea?
EDIT:
I did further investigation, the problem happens on hideCommands. Say I have 3 buttons displayed on the appbar. I call hideCommands to hide all 3 buttons. The icon of the 3 buttons would disappear on the appbar, then pile up at the top-left corner of the screen and then disappear. (i.e. there would be a flash of 3 piled up buttons at the corner of the screen).
You may be invoking showOnlyCommands when the AppBar is in the process of 'showing'. I've found that when calling these methods in the beforeshow or aftershow handler that this happens. This quote from Animating your UI sheds light on why:
Use fade in and fade out animations to show or hide transient UI or controls. One example is in an app bar in which new controls can appear due to user interaction.
The sample app shows/hides the buttons before the appbar is shown. You may be calling show on the app bar before calling showOnlyCommands.
A temporary hack for this problem is:
Set the button be invisible before calling showOnlyCommands or HideCommands.
Here is the code that I use for now:
/*
* #param {WinJS.UI.AppBar} appbar winControl
* #param {Array} array of appbar buttons to be shown
*/
function showOnlyCommands(appbarControl, buttonsToShow) {
var toShow = {};
for (var i = 0; i < buttonsToShow.length; i++) {
toShow[buttonsToShow[i].id] = true;
}
for (var i = 0; i < visibleButtonsList.length; i++) {
var id = visibleButtonsList[i].id;
if (!toShow[id]) {
// set the display property of the buttons to be hidden to "none"
var button = document.getElementById(id);
if (button) {
button.style.display = 'none';
}
}
}
// update the visible buttons list
visibleButtonsList = buttonsToShow;
// Note that we don't need to set the "display" property back for the buttons,
// because WinJS.UI.AppBar.showOnlyCommands would set it back internally
appbarControl.showOnlyCommands(buttonsToShow);
}
We have a parent Split view (NSSplitView), and two subviews, Content and SideBar (the sidebar is on the right).
What would be the optimal Cocoa-friendly way to toggle the SideBar view?
I would really love it, if the suggested solution includes animation
I really don't need any suggestions related to external plugins, etc (e.g. BWToolkit)
HINT : I've been trying to do that, but still I had issues hiding the divider of the NSSplitView as well. How could I do it, while hiding it at the same time?
Here's a pretty decent tutorial that shows how to do this: Unraveling the Mysteries of NSSplitView.
Hiding the divider is done in NSSplitView's delegate method splitView:shouldHideDividerAtIndex:.
You will have to animate the frame size change yourself if you don't like the way NSSplitView does it.
Easiest way to do it is as follows - and it's animated: [SWIFT 5]
splitViewItems[1].animator().isCollapsed = true // Show side pane
splitViewItems[1].animator().isCollapsed = false // hide side pane
I wrote a Swift version of the content in the link from #Nathan's answer that works for me. In the context of my example splitView is set elsewhere, probably as an instance property on an encompassing class:
func toggleSidebar () {
if splitView.isSubviewCollapsed(splitView.subviews[1] as NSView) {
openSidebar()
} else {
closeSidebar()
}
}
func closeSidebar () {
let mainView = splitView.subviews[0] as NSView
let sidepanel = splitView.subviews[1] as NSView
sidepanel.hidden = true
let viewFrame = splitView.frame
mainView.frame.size = NSMakeSize(viewFrame.size.width, viewFrame.size.height)
splitView.display()
}
func openSidebar () {
let sidepanel = splitView.subviews[1] as NSView
sidepanel.hidden = false
let viewFrame = splitView.frame
sidepanel.frame.size = NSMakeSize(viewFrame.size.width, 200)
splitView.display()
}
These functions will probably methods in a class, they are for me. If your splitView can be nil you obviously have to check for that. This also assumes you have two subviews and the one at index 1, here as sidePanel is the one you want to collapse.
In Xcode 9.0 with Storyboards open Application Scene select View->Menu->Show sidebar. CTRL-click Show Sidebar, in sent actions delete the provided one, click on x. From the circle CTRL drag to First Responder in application scene and select toggleSideBar to connect to. Open storyboard and select the first split view item and in attributes inspector change behaviour from default to sidebar. Run and try with view menu item show/hide. All done in interface builder no code. toggleSideBar handles the first split view item. https://github.com/Dis3buted/SplitViewController
I got some artifacts with the code above, likely because it was out of context. I am sure it works where it was meant to. Anyway, here is a very streamlined implementation:
// this is the declaration of a left vertical subview of
// 'splitViewController', which is the name of the split view's outlet
var leftView: NSView {
return self.splitViewController.subviews[0] as NSView
}
// here is the action of a button that toggles the left vertical subview
// the left subview is always restored to 100 pixels here
#IBAction func someButton(sender: AnyObject) {
if splitViewController.isSubviewCollapsed(leftView) {
splitViewController.setPosition(100, ofDividerAtIndex: 0)
leftView.hidden = false
} else {
splitViewController.setPosition(0, ofDividerAtIndex: 0)
leftView.hidden = true
}
}
To see a good example using animations, control-click to download this file.
If your NSSplitView control is part of a NSSplitViewController object, then you can simply use this:
splitViewController.toggleSidebar(nil)
