Is it possible to detect when the Today widget is expanded/contracted or 'Show More' button is tapped in Objective C?
There is no way to detect whether the Show More button has been tapped in Today Extension.
What you can do is determine if it's open with checking frame height.
You can add a boolean and set it in :
- (void)widgetActiveDisplayModeDidChange:(NCWidgetDisplayMode)activeDisplayMode withMaximumSize:(CGSize)maxSize {
if (activeDisplayMode == NCWidgetDisplayModeCompact) {
//non expanded
} else {
//expanded
}
}
You can also have a layout that doesn't need to know if it's opened or closed, that's what most apps do.
Hope this helps :)

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 try to implement a custom ContextMenu in a LongListSelector.
I'm not using the ContextMenu from Microsoft.Phone.Controls.Toolkit, it's basically the same as in the Rowi App:
(source: hiddenpineapple.com)
Approach 1
My list item toggles a VisualState on hold and an overlay is shown with controls in it.
The problem
I can't find a way to go back to the default state when the user clicks outside of the list item (as in the default ContextMenu).
Approach 2
I've implemented a custom template for the toolkit ContextMenu which looks exactly the same. I had to move its margin top to -itemHeight, as by default it is below the item.
The problem
The problem with this solution is, that it automatically closes itself when opening and I couldn't figure out how to avoid this.
Another problem was that it didn't work well with TiltEffect.IsTiltEnabled from the Toolkit (visual problems).
I need your help
Any suggestions on how to get this working?
Answer
Thanks to Cheese, now I know how to properly close the menu when the user clicks outside.
His suggestion was to get the coordinates of a Tap event on the current page, and check if it's inside the menu. When not, close the menu.
So I added a Tap listener to the page when the menu opens, and removed it when the menu closes. From the page listener I got the event coordinates and could check if it's inside the control which holds the menu (same size and position). I received the position of the control with Point leftUpperPoint = control.TransformToVisual(page).Transform(new Point(0, 0)) and the rightLowerPoint by adding the ActualWidth and ActualHeight.
But then I realized:
Why should I even calculate if the tap is inside the menu? I always want to close the menu when the user taps anywhere on the screen. If it's outside, yes. If it's on a menu button, yes.
Another modification I made was to listen for MouseLeftButtonDown instead of Tap as it also triggers when the user swipes.
So I removed this code and came up with the following:
private void ToggleMenu(object sender, System.Windows.Input.GestureEventArgs e)
{
PhoneApplicationFrame frame = ((PhoneApplicationFrame)Application.Current.RootVisual);
VisualState state = this.States.CurrentState;
if (state == null || state.Name == "DefaultState")
{
frame.MouseLeftButtonDown += MouseDownDelegate;
this.State = "MenuState";
}
else
{
frame.MouseLeftButtonDown -= MouseDownDelegate;
this.State = "DefaultState";
}
}
private void MouseDownDelegate(object sender, System.Windows.Input.MouseButtonEventArgs e)
{
ToggleMenu(sender, null);
}
This works perfectly!
Thanks to Cheese for the hint.
Something like this by #denniscode http://dotnet.dzone.com/articles/rowi-show-tap-menu
Approach 1 problem
The best solution would be:
Get the menus coordinates, when user makes a tap - you check are tap coordinates on menu or not, if not - dissmiss - simple.
Approach 2 problem
I guess you had some button in a corner and when you tapped on it - nothing happened? And when you dissmissed the Tilt all worked. It seems that tilt works faster than a click, so, tilt changes the button coordinates, and device thiks you have missed/or dragged off
You can use what #ScottIsAFool suggested and maybe create another Dependency Property on your TapMenu control of type UIElement named CloseWhenTappedElement and automatically listen for Tap events inside your control once set. For example
<Grid x:Name="TapArea"/>
<TapMenu CloseWhenTappedElement="{Binding ElementName=TapArea"}/>
I'm trying to write a Safari extension that consists of a button on the main toolbar with a popover tied to it, and a contextual menu item. The basic feel is modeled after the feel of the 1Password extension.
One of the jobs of the popover is to allow a person to log in. I'm also conditionally changing the action of the contextual menu item, and if a who person isn't logged in clicks the menu item I would like to show the popover allowing them to log in, but I can't find a way to do this in the developer guides.
How do I "show" a popover?
If you only have one toolbar item and one popover (and never plan to add more), then it's just one line. Assuming you've already assigned the popover to the toolbar item in Extension Builder, you can just use:
safari.extension.toolbarItems[0].showPopover();
But if you have more than one popover and (potentially) more than one toolbar item, here's a generalized function to open a popover, specified by its identifier, under the specified toolbar item in the active browser window:
function showPopover(popoverId, toolbarItemId) {
var toolbarItem = safari.extension.toolbarItems.filter(function (tbi) {
return tbi.identifier == toolbarItemId && tbi.browserWindow == safari.application.activeBrowserWindow;
})[0];
var popover = safari.extension.popovers.filter(function (po) {
return po.identifier == popoverId;
})[0];
toolbarItem.popover = popover;
toolbarItem.showPopover();
}
I have two buttons,if the first button is clicked two textfields will come and the second button dimension will change to next to the textfields.Now if i click the second button one textfield will appear.I did all those things.Now my question is if we click the second button,textfield will appear with what ever the dimensions we have given,but if we click the second button after clicking the first button also dimensions should change.Can any one help to do this.
Thank You
you can add multiple selectors on a single button for different control states
Your question is vaguely phrased. If I understood correctly, when the second button is pressed, you want two different actions done depending on whether the first button has previously been pressed or not. If that's the case, the solution is to define a boolean flag, which will be set to YES when the first button is pressed, and will be set to NO (if needed) after the second button's action is completed.
In your header file:
#interface yourViewController: UIViewController {
BOOL firstButtonFlag;
}
And in yourViewController.m file:
-(void)viewDidLoad {
firstButtonFlag = NO; // technically redundant line, just to show the concept
}
-(IBAction)firstButtonPressed {
firstButtonFlag = YES;
// whatever action you want done
}
-(IBAction)secondButtonPressed {
if (firstButtonFlag) {
// whatever action if first button had been pressed before
firstButtonFlag = NO; // resetting the flag for next round
}
else {
// whatever action if first button had NOT been pressed before
}
}
There is a button at bottom right of iPad keyboard which is to hide the keypad.
How can I interact with it programmatically? (get the button then send UIControlEventTouchUpInside to it).
Does anyone know this?
[Edit]
In my case, the keyboard is shown on a modal view.
Overriding disablesAutomaticKeyboardDismissal to return NO as below allows you to dismiss the keyboard when you resignFirstResponder, even when your UITextView is on a modal view. You should put this code to your view controller, from which you initiate the keyboard:
- (BOOL)disablesAutomaticKeyboardDismissal {
return NO;
}
Source: https://stackoverflow.com/a/6268520
In general, you would send the resignFirsResponder message to the active input view.
Something like this? I can't remember where I found this code but I used it to toggle the on-screen keyboard because it would be hidden by default if a bluetooth one was connected.
- (void) toggleKeyboard(UIKeyboardImpl * keyImpl){
if (UIKeyboardAutomaticIsOnScreen()) {
UIKeyboardOrderOutAutomatic();
} else {
UIKeyboardOrderInAutomatic();
}
Edit
I found where I got this code from. It works fine but the catch is that you need to import the private framework GraphicsServices, which would most likely get your app rejected from the App store.
