onkeypress is fired only for character keys. onkeydown will fire for all keys pressed. I found some explanation of differences between all key events here Try it with onkeydown and it worked: <input type=”text” @onkeydown=”@Enter” /> In the event handler you will have to do this (notice that I check for both Enter and NumpadEnter … Read more
TL;DR: These are the rules you should follow: When getting text input from the user, use the keypress event along with e.key For shortcuts and other combinations, the built-in way is to use keydown/keyup and check the various modifier keys. If you need to detect chords, you may need to build a state machine. Background … Read more
Add UISearchBarDelegate in .h Also set SearchBar’s object delegate to self. Add this to the UISearchBarDelegate’s method: – (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar { [searchBar resignFirstResponder]; // Do the search… } Swift func searchBarSearchButtonClicked(_ searchBar: UISearchBar) { searchBar.resignFirstResponder() }
Hi I’d used following workaround: As far as my content view is a subclass of LinearLayout (could be any other view or view group), I’d overridden onMeasure method lilke following: @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { final int proposedheight = MeasureSpec.getSize(heightMeasureSpec); final int actualHeight = getHeight(); if (actualHeight > proposedheight){ // Keyboard is … Read more
You can send key events, and anything listening for them will get them, but they will not change the input, so you will not see the letter A appear, for example. This is mostly a security thing; see “Manually firing events” for a discussion about that. So, if you want the letter to appear, you … Read more
Go to Resharper -> Options, in the left treeview select Editor Behavior and uncheck the last option Use Tab/Shift Tab keys for structural navigation. Update for Resharper 2016.3.1. Thanks to @Jordan for pointing this out!
Consider reading this page about handling exceptions.. It should help. As @abarnert has said, do sys.exit() after except KeyboardInterrupt:. Something like try: # DO THINGS except KeyboardInterrupt: # quit sys.exit() You can also use the built in exit() function, but as @eryksun pointed out, sys.exit is more reliable.
This I think will do the job, or if not is very close and will need only minor tweaking. The thing you have to remember is that you can’t reliably tell anything at all about any character that may be typed in a keydown or keyup event: that all has to be done in a … Read more
I am working on DOM Keyboard Event Level 3 polyfill . In latest browsers or with this polyfill you can do something like this: element.addEventListener(“keydown”, function(e){ console.log(e.key, e.char, e.keyCode) }) var e = new KeyboardEvent(“keydown”, {bubbles : true, cancelable : true, key : “Q”, char : “Q”, shiftKey : true}); element.dispatchEvent(e); //If you need legacy … Read more
