user-interaction

Is there a way to make R wait for console input before continuing? Let's say I source two scripts like this in a main script called run.R: # some more R Code here source("script1.R") source("script2.R") # some more R Code there Script1 contains some readLine statement that asks the user for a username. Unfortunately if I just run the entire run.R file R doesn't wait for the username to be entered. It starts script2.R before the username is entered which leads to an error because the 2nd script needs the username. I have an ugly workaround for this using R Studio's .rs.askForPassword which

I know that for traditional UIViews, I can set "enable user interaction" flag to NO, and the view will no longer respond to touches, letting the views below them receive touches. Is there some way to implement the same "tap through" functionality in Sprite Kit? So far I've only seen people using "Touches began", getting the point and asking the scene for nodes at that point. The problem with this approach is - if I want to add overlays on top of sprites (like monster life points, etc) they will also respond to touches. So far I'm trying to avoid this problem by creating custom classes for

I need to disable user interaction on front view when rear view is revealed. Found some others asking the same thing but can't really understand where or how to implement the code that I've seen. Ex: I found this code from link , - (void)revealController:(SWRevealViewController *)revealController willMoveToPosition:(FrontViewPosition)position { if(position == FrontViewPositionLeft) { self.view.userInteractionEnabled = YES; } else { self.view.userInteractionEnabled = NO; } } - (void)revealController:(SWRevealViewController *)revealController didMoveToPosition:(FrontViewPosition)position { if

I have a view which contains two views. One of those views contains two buttons and some text labels. The other one, with alpha set to 0.25, has an UIActivityIndicatorView to tell the user that the app is working and he must wait until it finishes. If the user touch a button while the UIActivityIndicatorView is spinning, when the UIActivityIndicatorView stops, the app remember the user action and responds to it. How can I discard the user interaction that occur while the UIActivityIndicatorView is spinning? Thanks for reading. P.D.: Like is commented in this thread , I prefer do not to use any

I would like to handled SelectionChanged event in WPF DataGrid element for user interaction/selection only and skip if it's due to binding or other set values. Any idea how I will determine if the Selection is changed by user interaction? Or any alternate event that would do similar task? Maybe try combine SelectionChanged event with PreviewMouseDown event. When user click a row you set some property and in SelectionChanged event handler check if than property was changed. Sample code XAML: <DataGrid SelectionChanged="OnSelectionChanged" PreviewMouseDown="OnPreviewMouseDown"> <!--some code-->

I need to perform a particular action in a view controller when user don't touch a particular screen for 3 seconds. How can I do that in iOS? Override the view's touches began method and reset a timer when you get touches. - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { [self.timer invalidate]; self.timer = [NSTimer scheduledTimerWithTimeInterval:3.0 target:self selector:@selector(inactivityTimerFired) userInfo:nil repeats:NO]; [super touchesBegan:touches withEvent:event]; } You could target the view controller instead of self if you need to. Add an NSTimer property/ivar to

Originally I create this shiny interface that takes in a parameter "company id" and "date", but here we have a problem: most people dont know the companies we work with by their id, only their name, i.e. (McDonalds, Radioshack). So I want to ideally create a search function like this My current idea is to pass in a table including a list of all our partner companies and their ids to global.R. Then pass in the textInput as the search variables and perform the search on server side. However, I get lost on how to pass searchResults back into the UI on a selectInput panel? My current code: ui.R
