I'm dealing with nw.js recently and came across with a problem I couldn't figure out why. Problem like this: when i drag the app window the first time after i launch my app, the height changes(about 20px higher), and then it keeps the same.

I use SkiaSharp canvas to draw the main game screen, and then there are various Xamarin.Forms Buttons around the UI. This all works fine on when used directly on iPhone or iPad using a finger. However, when I connect a mouse (e.g., through a MacBook or otherwise), the buttons start working with about 10% chance after mouse-clicking on the SkiaSharp canvas (and not receiving the mouse click events with 90% chance). The SkiaSharp canvas itself works just fine.
If I bring up the iOS app launch menu from the bottom (which probably somehow temporarily exists the mouse navigation on the app), the buttons start working again with the mouse. But if I click the SkiaSharp canvas again with the mouse, the buttons have a high chance of becoming disabled again. If I change to using a finger, all works fine (even if the mouse clicks were not being registered immediately before). However, mouse clicks are not being registered even after touching with a finger, so finger-touching does not reset the issue with the mouse (but bringing up the menu from the bottom does).
We found this bug by testing the iOS game on MacBook Pro (the iOS apps recently came available on the App Store) but the same issue persists also directly with an iPad / mouse combination. It seems to be some sort of an issue between using a mouse (on iPad or on MacBook Pro), SkiaSharp canvas and Xamarin.Forms buttons.
Does anyone know what the root cause of the problem is and what is the workaround?
Not an answer as such, but some more information about reproducing the issue: A simpler repro case may be this small project: https://github.com/jrc14/TraceMatching/ .
Don't worry too much about what it's doing, but note that you're mean to click in the grey Skia canvas in the middle to create 'targets' - and that after you've done that, mouse-clicks are getting lost.
If you run it on a Mac, you'll see that, though the clicks get lost after you've clicked on the Skia canvas, they will start being received again if you click on something else (another app, or the Mac background).
(further edit) - after some noodling around I did find a workaround. If, once you've finished processing the touch action on the SKCanvasView, you reset its EnableTouchEvents property (i.e. set it to false, then back to true again), it seems that the clicks don't get lost any more,
I am developing a mac application using an NSSplitView. There are 3 columns, a menu on the left, an NSTableView in the middle and a detail view on the right. All my components use constraints and none of them are set to restrict width or height
When I press the button to go into fullscreen mode, the application does go fullscreen, however the actual content doesn't resize, it just stays the same and a large black border forms around the application.
What are the possible causes for this and how do I debug to find out where the issue lies?
Occasionally when I scroll horizontally in an app using the magic mouse, the current tab or page I'm scrolling on freezes and thereon in that app, scrolling is completely non-functional.
For example, if I'm using Safari and I scroll horizontally to go back to the previous link, the current tab freezes, stuck in the middle of the animation. If I close the frozen tab, the other tabs work fine, but I can't scroll vertically or horizontally in them. I have to scroll using the scrollbar. No other apps are affected and if I restart the affected application, everything goes back to normal and the mouse scrolling is functional again.
Has anybody else had this issue? Any ideas on how to fix this?
I was running Lion when this issue started. I updated to Mavericks hoping it would be fixed, but no luck. I'm currently running Mavericks GM on an iMac (latest model).
This is an issue after installing Mavericks. Go to System Preferences/General and click on Show scroll bars: Check "Always". Hope this helps.
We just set up a whole bunch of development MacBooks in our office. We all set up the computers exactly the same as far as I can tell (just installing xcode and not changing any settings). We even distributed the exact same xcode project to everyone to test whether or not everyone was set up correctly. For some reason though, my iPad simulator incorrectly renders the positions of Objects on the UIView controller.
I can make a really basic application and slap down a UIView controller with the storyboard editor in xcode 4.3.1 (newest version ATM), and add a button to it. When I run this on the simulator, it will look fine on the iPhone one, but when I try to view it in the iPad, it seems that some elements will scale to the iPad resolution fine, but others will not. The components that do not, seem to be in the place that they would be if they had been rendered on the iPhone.
The weirdest part of this problem is that I can't find anyone online who has had this same issue. I have already tried deleting and re-installing xcode and the same thing still happens. I fear I might have to re-install the OS and start from scratch.
How it looks on the iPhone simulator:
And on the iPad simulator:
I don't think that's an SDK issue, I bet that you are writing code that fits for the iPhone screen and not for the larger iPad screen.
I think that you added just the button and is Autoresizing Mask is not set properly.
I've done some measurement an it seems that:
The distance from the top of the view is in fixed (~360px);
The width is fixed (~260px);
You need to give the button a fixed distance from the bottom (as it should stay on under the plot) and remove the left fixed margin so it can be centered.
You need to take a look at the UIViewAutoresizingMask for the UIView's autoresizingMask property.
button.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin;
I wouldn't ask if I couldn't find it anywhere else, but I've run into a problem. I have a complete storyboard built in Xcode, but I've lost it on the screen. Pressing the +/- buttons in the bottom right zoom in and out, but nothing shows up. I know the app is there because it runs fine, but all of my views are off the screen and I have no idea how to get them back. And since I'm on a desktop, there's no way to pan (maybe the same issue happens on a laptop?)
How do I get my storyboard back?
I searched for a "zoom all" in the menus but can't find one.
This is so frustrating. Grrr. I can't work on my storyboard until I can find it on the canvas. I can't find it on the canvas because I can't pan and have no idea where it is.
Right click on your storyboard file => Open As => iOS Storyboard
