You can now do this in pure CSS, so no JavaScript needed 😁 The new CSS pseudo-class :focus-within would help for cases like this and will help with accessibility when people use tabbing for navigating, common when using screen readers. .parent:focus-within { border: 1px solid #000; } The :focus-within pseudo-class matches elements that either themselves … Read more
This works. Not sure if it’s the best solution or not. // SCROLL VIEW HACK // BOGUS ScrollView view = (ScrollView)findViewById(R.id.scrollView); view.setDescendantFocusability(ViewGroup.FOCUS_BEFORE_DESCENDANTS); view.setFocusable(true); view.setFocusableInTouchMode(true); view.setOnTouchListener(new View.OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { v.requestFocusFromTouch(); return false; } });
document.activeElement, it’s been supported in IE for a long time and the latest versions of FF and chrome support it also. If nothing has focus, it returns the document.body object.
If focus_force() is not working you can try doing: window.after(1, lambda: window.focus_force()) It’s essentially the same thing, just written differently. I just tested it on python 2.7. root.focus_force() wouldn’t work but the above method did.
No, you can only focus on one element at a time.
You can use the FocusManager.FocusedElement attached property for this purpose. Here’s a piece of code that set the focus to TxtB by default. <StackPanel Orientation=”Vertical” FocusManager.FocusedElement=”{Binding ElementName=TxtB}”> <TextBox x:Name=”TxtA” Text=”A” /> <TextBox x:Name=”TxtB” Text=”B” /> </StackPanel> You can also use TxtB.Focus() in your code-behind if you don’t want to do this in XAML.
$(document.activeElement) will return the currently focused element and is faster than using the pseudo selector :focus. Source: http://api.jquery.com/focus-selector/
Use this attributes in your layout tag in XML file: android:focusable=”true” android:focusableInTouchMode=”true” As reported by other members in comments it doesn’t works on ScrollView therefore you need to add these attributes to the main child of ScrollView.
Set focus on the first text field: $(“input:text:visible:first”).focus(); This also does the first text field, but you can change the [0] to another index: $(‘input[@type=”text”]’)[0].focus(); Or, you can use the ID: $(“#someTextBox”).focus();
What you describe works exactly as expected, assuming that you’ve set the HideSelection property of the ListView control to False. Here’s a screenshot for demonstration purposes. I created a blank project, added a ListView control and a TextBox control to a form, added some sample items to the ListView, set its view to “Details” (although … Read more
