[CLOSED] KeyMap and browsers events

[jdacosta]

Hi,

I'm using Ctrl+W and Ctrl+T shortcuts, but it's always the browser event which is fired.

The following code close the tab and doesn't display my alert.

@(
    X.Viewport().ID("Viewport").Layout(LayoutType.Border)
    .KeyMap
    (
        X.KeyMap()
        .Target("={Ext.isGecko ? Ext.getDoc() : Ext.getBody()}")
        .Binding(b => {
            b.Add(Html.X().KeyBinding().Ctrl(true).KeysString(((int)KeyCode.W).ToString()).DefaultEventAction(EventAction.PreventDefault).Handler("alert('click');"));
        })
    )
)

But the following is working, the only change is the keycode 'A'

@(
    X.Viewport().ID("Viewport").Layout(LayoutType.Border)
    .KeyMap
    (
        X.KeyMap()
        .Target("={Ext.isGecko ? Ext.getDoc() : Ext.getBody()}")
        .Binding(b => {
            b.Add(Html.X().KeyBinding().Ctrl(true).KeysString(((int)KeyCode.A).ToString()).DefaultEventAction(EventAction.PreventDefault).Handler("alert('click');"));
        })
    )
)

How can I use Ctrl+W or Ctrl+T without firing my browser event (close/open tabs)

Thanks a lot !

Hi @jdacosta,

There is always a problem with overriding a browser's hot keys, especially, with serious ones like Ctrl+W, due to browser reason. First, not all browsers allows to do that. Second, if find a solution for some browser, it might not work in another browser. Besides, it can be not nice for an end-user who is used to use browser hot keys and expected the certain behavior.

Personally, I would strongly recommend not to do that.

I also do not reccomend it because you change habitual behaviour of browser (user is accustomed for particular behaviour for particular hot keys but you change it)
