Java : ignore single click on double click?

阅读更多关于 Java : ignore single click on double click?

can anyone think of a good way to ignore the single click that comes with a double-click in Java ? I'm looking to have different behaviors for each such that: single-click paints crosshairs on the click point double-click selects an object on the screen, but should not paint crosshairs on the click point ... can anyone think of a way to do this ? Some sort of timer set-up maybe ? An ideas appreciated :-) <disclaimer> ...and yes, I know I'm committing a most heinous usability / UI faux pas. </disclaimer> EDIT #2: Even though this works the delay due to the timer is maddening - I'm abandoning

SVG click events not firing/bubbling when using <use> element

阅读更多关于 SVG click events not firing/bubbling when using element

I have come across an interesting bug (?) whereby if you embed the SVG using <use> as part of a link (an icon for example) – the icon itself does not register a click event in jQuery, but clicking the text does. I think this is due to SVG events not bubbling up? If you embed the SVG directly, the link triggers regardless of whether you click the text or the icon. A simple test case I created can be seen here: SVG <use> bug test case . Use pointer-events: none; on the svg. It worked for me. The element is never the target of mouse events; however, mouse events may target its descendant elements

Click not working on RecyclerView in CoordinatorLayout when scrolling

阅读更多关于 Click not working on RecyclerView in CoordinatorLayout when scrolling

I am facing a strange behaviour with a RecyclerView as a second child of CoordinatorLayout, just after an AppBarLayout (as described in a lot of examples). My problem is when I scroll the recycler view and I want to click on a particular item. Sometimes I need to click 2 times to select that item, it seems to be linked to the fling behaviour. For example, if I scrolled to the bottom of the recycler view, then if I fling my finger from the bottom of the screen to the top (in order to see more data, but in my case I can't see more data since I am already to the bottom) and then quickly click on

Raise button (or any control) click event manually. C#

阅读更多关于 Raise button (or any control) click event manually. C#

问题 Can anyone tell me how to raise click event of button control (or for that matter for any event). Platform: .net 2.0/3.0/3.5 Language: c# Domain: Windows Application, WinForms, etc. 回答1: You can use the Button.PerformClick method. 回答2: Maybe the solution is much more simple: Maybe you don't really want your code "to click the button". Do you just want to run the code which is behind the button from another place in the form? If yes, put the code into a separate method (like "DoActionXXX") and

jquery trigger action on focus or click but not both

阅读更多关于 jquery trigger action on focus or click but not both

问题 I have this sample code: $myTrigger .click(function(e){ alert('click'); }) .focus(function(e){ alert('focus'); $(this).click() }) The intent is that I want something to happen when you click on $myTrigger. If, on the other hand, you tab onto it via the keyboard (ie, focus) I want the exact same thing to happen, so I ask it to click. The catch is if I click on it, it also focuses. So both alerts are going off. Is there a way to prevent the focus event from going off when clicking? UPDATE: Ajm
