jointjs: prevent adding vertex by clicking on link

I would like to add a label to a link by doing a doubleclick on the link. So this is my attempt:
paper.on({
'cell:pointerdblclick': function(cellView, event, x, y){
if (cellView.model.isLink()) {
cellView.model.label(0, {
position: .5,
attrs: {
rect: { fill: 'white' },
text: { text: 'my label' }
}
});
}
},
});
The problem is, that by doing a doubleclick there is also a vertex beeing created at the same time. How can I prevent that?
Or what would be another simple way to let users add a label for a link?

As shown in the docs (http://jointjs.com/api#joint.dia.LinkView:addVertex) just add this part to joint.dia.Paper:
interactive: function(cellView) {
if (cellView.model instanceof joint.dia.Link) {
// Disable the default vertex add functionality on pointerdown.
return { vertexAdd: false };
}
return true;
}

move item control bar videojs

I'm using the video.js 4.12 library and I want replace control bar items. For example, move one of my custom buttons to the 2nd slot of the control bar.
How do I change the order of items on the taskbar? I had no luck on Google.

Videojs place good class on elements. By this way you can identify control bar's elements.
To handle the item's order I used Jquery :
var createPrevButton = function() {
var props = {
className: 'vjs-control player-prev-button', //We use this class in Jquery
innerHTML: '<div class="vjs-control-content"></div>',
role: 'button',
'aria-live': 'polite',
tabIndex: 0
};
return videojs.Component.prototype.createEl(null, props);
};
var myPlayer = me.player = videojs(me.idVideo, {
plugins : { chapters : {} },
children: {
controlBar: {
children: [
{
name: 'playToggle'
},
{
name: 'currentTimeDisplay'
},
{
name: 'timeDivider'
},
{
name: 'durationDisplay'
}
/*
...........
*/
]
}
}
});
$(".player-prev-button").insertAfter(".vjs-play-control");
$(".player-next-button").insertAfter(".player-prev-button");
After the instanciation of my player just handle item by Jquery.
I think it's better than use CSS.
But the best way should be by videojs's option or somethink like that

How can I change the color of the selected point in Highcharts?

I have an HighCharts line plot in which the user can click points using this code:
plotOptions: {
series: {
point: {
events: {
click: function(event) {
// some processing
}
...
I want to change the color of the selected point.
I know that I could write :
marker: {
states: {
select: {
fillColor: 'red',
...
But, in my case, I really need to do this inside click, How can I do it ?

You can always use the update function for that:
plotOptions:{
series:{
marker:{
states:{
select:{
lineColor:'red',
fillColor:'red'
}
}
},
point:
{
events:{
click: function(){
this.setState("select");
this.update({
marker:{
fillColor:'red',
lineColor:'red',
}
})
}
}
}
}
},
When this refers to the point the user clicked.
As you can see, I composed a custom "select" state with some custom properties, and applied this state when user clicks a point. I also used update in order to change the point marker attributes, so I make sure the point reserves the new attributes after the state is no longer active:

Set default focus on first item in grid list

Once a grid is rendered how can I set focus to the first item. I am running into a problem where when the grid is updated (collection changes) then focus is lost for the entire application .
I am using the moonstone library.
{
kind: "ameba.DataGridList", name: "gridList", fit: true, spacing: 20, minWidth: 300, minHeight: 270, spotlight : 'container',
scrollerOptions:
{
kind: "moon.Scroller", vertical:"scroll", horizontal: "hidden", spotlightPagingControls: true
},
components: [
{kind : "custom.GridItemControl", spotlight: true}
]
}

hightlight() is a private method for Spotlight which only adds the spotlight class but does not do the rest of the Spotlight plumbing. spot() is the method you should be using which calls highlight() internally.
#ruben-ray-vreeken is correct that DataList defers rendering. The easiest way to spot the first control is to set initialFocusIndex provided by moon.DataListSpotlightSupport.
http://jsfiddle.net/dcw7rr7r/1/
enyo.kind({
name: 'ex.App',
classes: 'moon',
bindings: [
{from: ".collection", to: ".$.gridList.collection"}
],
components: [
{name: 'gridList', kind:"moon.DataGridList", classes: 'enyo-fit', initialFocusIndex: 0, components: [
{kind:"moon.CheckboxItem", bindings: [
{from:".model.text", to:".content"},
{from:".model.selected", to: ".checked", oneWay: false}
]}
]}
],
create: enyo.inherit(function (sup) {
return function () {
sup.apply(this, arguments);
// here, at least, the app starts in pointer mode so spotting the first control
// isn't apparent (though it would resume from that control upon 5-way action).
// Turning off pointer mode does the trick.
enyo.Spotlight.setPointerMode(false);
this.set("collection", new enyo.Collection(this.generateRecords()));
};
}),
generateRecords: function () {
var records = [],
idx = this.modelIndex || 0;
for (; records.length < 20; ++idx) {
var title = (idx % 8 === 0) ? " with long title" : "";
var subTitle = (idx % 8 === 0) ? "Lorem ipsum dolor sit amet" : "Subtitle";
records.push({
selected: false,
text: "Item " + idx + title,
subText: subTitle,
url: "http://placehold.it/300x300/" + Math.floor(Math.random()*0x1000000).toString(16) + "/ffffff&text=Image " + idx
});
}
// update our internal index so it will always generate unique values
this.modelIndex = idx;
return records;
},
});
new ex.App().renderInto(document.body);

Just guessing here as I don't use Moonstone, but the plain enyo.Datalist doesn't actually render its list content when the render method is called. Instead the actual rendering task is deferred and executed at a later point by the gridList's delegate.
You might want to dive into the code of the gridList's delegate and check out how it works. You could probably create a custom delegate (by extending the original) and highlight the first child in the reset and/or refresh methods:
enyo.Spotlight.highlight(this.$.gridList.childForIndex(0));

Ruben's answer adds on to my answer that I posted in the Enyo forums, which I'm including here for the sake of completeness:
Try using
enyo.Spotlight.highlight(this.$.gridList.childForIndex(0));
I added a rendered() function to the Moonstone DataGridList sample in the Sampler and I found that this works:
rendered: function() {
this.inherited(arguments);
this.startJob("waitforit", function() {
enyo.Spotlight.highlight(this.$.gridList.childForIndex(0));
}, 400);
},
It didn't work without the delay.

Get element that called qTip?

I would like to get the element that called the qtip popup. In the documentation here it lets you set the position. I want to set the position using a jquery selector like $(this).find('.icon'). The problem is that this isn't the element that called the qtip (I think it's window).
Does anyone know how I can get the handle that called it (like it would if I set target to false)?
Thanks.
In the qtip source code I found this:
if(config.position.target === false) config.position.target = $(this);

Here's the solution I came up with and it seems to work. There probably is a better way to do it if I modified the qtip script but I want to leave that alone.
$(".report-error").qtip(
{
content: 'test content',
position:
{
adjust:
{
screen: true
},
target: false, //it is changed in the 'beforeRender' part in api section. by leaving it as false here in the qtip it will set it as the position I need using $(this)
corner:
{
target: 'bottomMiddle',
tooltip: 'topRight'
}
},
show:
{
when:
{
event: 'click'
}
},
style:
{
name: 'cream',
tip:
{
corner: 'topRight'
},
padding: 0,
width: 400,
border:
{
radius: 5,
width: 0
}
},
hide:
{
when:
{
event: 'unfocus'
}
},
api:
{
beforeRender: function() { //get the position that qtip found with $(this) in it's script and change it using that as the start position
this.options.position.target = $(this.elements.target).find('.icon');
this.elements.target = this.options.position.target; //update this as well. I don't actually know what it's use is
}
}
});
