Draggable objects alignment - html

Im trying to make draggable objects align to each other from far.
its allmost done but the thing that is not working is if you watch carefully at the example, the helpers are 1 move behind.. if u move it 1 pixel up the helpers will go to the -1 place u were.. and only next move be where your mouse was :(
hope u understand HERE IS A WORKING CODE (DEMO)
any ideas what is wrong with it?
i think the problem is in this part but i dont know what to change that will work without this bug:
drag: function(event, ui) { drawGuideLines($(this)); },
start: function(event, ui) { removeAlignLines($(this)); },
stop: function(event, ui) {
rebuildAlignLines($(this));
linesTimeout = setTimeout("hideGuideLines()", 100);
},

Sounds like a bug, the drag event is not called after the last move. The problem is very visible if the user move the mouse quickly.
As workaround, you could set up an interval function durring the dragging time and draw the grid lines every 100ms :
Update jsbin : http://jsbin.com/oqohuq/4/edit
var handleInterval = null;
$(".draggable").draggable({
opacity : 0.35,
handler : "._header",
stack : ".draggable",
grid: [1, 1],
refreshPositions: true,
snap: ".drag_alignLines", // Setting snap to alignment lines
snapTolerance: 10,
snapMode: "inner",
drag: function(event, ui) { drawGuideLines($(this)); },
start: function(event, ui) {
//Init the interval here
var self = $(this);
handleInterval = setInterval(function(){ drawGuideLines(self);},100);
removeAlignLines($(this)); },
stop: function(event, ui) {
//Clear interval here
clearInterval(handleInterval);
rebuildAlignLines($(this));
linesTimeout = setTimeout("hideGuideLines()", 100);
}//Don't forget to remove the last coma!
});

i have a geojson layer button and when i click i have to zoom to the particular layer

this is my layer and i have assigned it to a button, but the zoom is not working when I click the layer button. i tried adding the zoom inside the layer but its not working.
rainfall1 = new ol.layer.Vector({
//title: 'CA_DEVELOPMENT_PLAN',
// extent: [-180, -90, -180, 90],
visible:false,
source: new ol.source.Vector({
url:"./data/village.geojson",
zoom: 12,
format: new ol.format.GeoJSON()
}),
style:function(feature) {
labelStyle.getText().setText(feature.getProperties().CA_NAME);
return style1;
},
declutter: true,
});
document.getElementById("lyr").onclick = function() {
layer1.setVisible(!rainfall1.getVisible());
};
var bindLayerButtonToggle = function (lyr, layer) {
document.getElementById(lyr).onclick = function() {
layer.setVisible(!layer.getVisible());
};
}
bindLayerButtonToggle("lyr", rainfall1);
setVisible will not zoom to a layer, it just turns it on or off.
Instead, you would have to update the view extent, and match it with the layer extent
map.getView().fit(rainfall1.getSource().getExtent());
#JGH's answer might work in some cases but if this is the first time the layer is made visible the source will not be loaded, so if there are no features you will need to wait for it to load before zooming.
if (rainfall1.getSource().getFeatures().length > 0) {
map.getView().fit(rainfall1.getSource().getExtent());
} else {
rainfall1.getSource().once('featuresloadend', function() [
map.getView().fit(rainfall1.getSource().getExtent());
});
}

Extending sap.ui.core.Icon with hover event or mouseover

I extended sap.ui.core.Icon with hover event handling:
sap.ui.define(function () {
"use strict";
return sap.ui.core.Icon.extend("abc.reuseController.HoverIcon", {
metadata: {
events: {
"hover" : {}
}
},
// the hover event handler, it is called when the Button is hovered - no event registration required
onmouseover : function(evt) {
this.fireHover();
},
// add nothing, just inherit the ButtonRenderer as is
renderer: {}
});
});
The event onmouseover is never fired. I also used this extension for sap.m.Button and it works. But I need this for sap.ui.core.Icon.
I also tried this jquery example but it did not work at all.
$("testIcon").hover(function(oEvent){alert("Button" + oEvent.getSource().getId());});
Please, do you have any idea why event handler onmouseover is not called for sap.ui.core.Icon? Or can you propose some other solution?
Bellow is how I added icon to my sap.suite.ui.commons.ChartContainer:
var oFilterIcon = new HoverIcon({
tooltip : "{i18n>filter}",
src : "sap-icon://filter",
hover : function(oEvent){alert("Button" + oEvent.getSource().getId());},
});
this.byId("idChartContainer").addCustomIcon(oFilterIcon);
This is my analysis:
Your new custom Control Icon for hover is correct. If you will use it independently it will work correctly .
However, your custom control will not work as your icons are converted to sap.m.OverflowToolbarButton when you use ChartContainer.
I looked into the source code of Chart Container and below is the code:
sap.suite.ui.commons.ChartContainer.prototype._addButtonToCustomIcons = function(i) {
var I = i;
var s = I.getTooltip();
var b = new sap.m.OverflowToolbarButton({
icon: I.getSrc(),
text: s,
tooltip: s,
type: sap.m.ButtonType.Transparent,
width: "3rem",
press: [{
icon: I
}, this._onOverflowToolbarButtonPress.bind(this)]
});
this._aCustomIcons.push(b);
}
So, you Icon is not used but its properties are used. As this is standard code, your hover code of Custom icon is not passed along.
One solution will be to add the onmouseover to sap.m.OverflowToolbarButton :
sap.m.OverflowToolbarButton.prototype.onmouseover=function() {
alert('hey')
};
However, this is dangerous as all OverflowToolbarButton button start using this code and I will not recommend it.
Next solution would be to overwrite the private method:_addButtonToCustomIcons ( again not recommendred :( )
sap.suite.ui.commons.ChartContainer.prototype._addButtonToCustomIcons = function(icon) {
var oIcon = icon;
var sIconTooltip = oIcon.getTooltip();
var oButton = new sap.m.OverflowToolbarButton({
icon : oIcon.getSrc(),
text : sIconTooltip,
tooltip : sIconTooltip,
type : sap.m.ButtonType.Transparent,
width : "3rem",
press: [{icon: oIcon}, this._onOverflowToolbarButtonPress.bind(this)]
});
this._aCustomIcons.push(oButton);
//oButton.onmouseover.
oButton.onmouseover = function() {
this.fireHover();
}.bind(oIcon);
};
Let me know if this helps u. :)

How to make horizontal splitter with jQuery UI Resizable()

Horizontal line / handle, that once clicked and dragged, makes upper div decrease in size while bottom div increase, and vice versa. The idea is to implement a similar splitter to the one present on JSFiddle four windows interface.
The implementation Demo on JSFiddle is here
Javascript:
$(function() {
var bottomElem = $(".resizable-bottom");
var bottomElemOriginalHeight = bottomElem.height();
$(".resizable-top").resizable({
handles: 's',
resize: function(event, ui) {
bottomElem.height(bottomElemOriginalHeight - (ui.element.outerHeight() - ui.originalSize.height));
},
stop: function(event, ui) {
bottomElemOriginalHeight = bottomElem.height();
},
//This has the effect of minHeight for bottomElem
maxHeight: $(".resizable-top").height()
});
});

how do i add in mootools an onComplete event on a morph attached to a mouseleave?

here is my code:
$('myButton').addEvents({
mouseenter: function(){
$('myImage').setStyle('display','block');
$('myImage').morph({
'duration': 500,
'transition': Fx.Transitions.Sine.in,
'opacity': 1,
'top': -205
});
},
mouseleave: function(){
$('myImage').morph({
'opacity': 0,
'top': -175,
'onComplete': hidemyImage
});
}
});
function hidemyImage() {
$('myImage').setStyle('display','none')
}
the onComplete inside the mouseleave does not work as expected... it hides the image immediately when i move away from myButton instead of hiding it after the morph has finished... i tried several solutions but none worked so far. any idea / help? thanks in advance!
you need to work with the instance and not pass on things in the morph function directly, that takes properties to morph and it probably runs your function immediately in the hope it will return a property value. you can do el.set('morph', {onComplete: hideImagefn}) before that and it will work but read on...
one way to do it is to set your morph options/instance once and work with it afterwards like so:
(function() {
var img = document.id('myImage').set('morph', {
duration: 500,
transition: Fx.Transitions.Sine.in,
link: 'cancel',
onStart: function() {
this.element.setStyle('display', 'block');
}
}), fx = img.get('morph');
// of you can just do var fx = new Fx.Morph(img, { options});
document.id('myButton').addEvents({
mouseenter: function(){
fx.start({
opacity: 1,
top: -205
});
},
mouseleave: function(){
fx.addEvent('complete', function() {
this.element.setStyle('display', 'none');
this.removeEvents('complete');
}).start({
opacity: 0,
top: -175
});
}
});
})();
the start ensures its always visible when mouseovered, the link is cancel which means it will stop execution if you mouse out too early and if you do mouseout, it will then hide the image and remove the onComplete event so that if you show it once more, it stays visible when it comes into view.
if you don't plan on being able to bring it back you can clean-up better and even use event pseudos like onComplete:once etc - though thats part of Event.Pseudos from mootools-more.
in general - .get/.set morph is your setup. el.morph() passes values to morphInstance.start()

Using jQuery Cycle on Hover Only

I'm trying to get jQuery Cycle to only run when the slideshow is being hovered (which is the opposite of the functionality that they have built in).
Here's where I'm at: http://jsfiddle.net/zSBMU/
$(document).ready(function() {
$('.slideshow').hover(
function() {
$(this).cycle({
fx: 'fade',
speed: 600,
timeout: 300,
pause: 0
});
},
function(){
$(this).cycle('stop');
}
).trigger('hover');
​ });
The first time you hover, it's great, works fine. But if you try to hover the same one again, it only goes through one fade instead of looping through again.
Any ideas?
Please ignore some of the gross code, working with a pretty old theme here, trying to clean it up!
You're using "stop" and recreating the cycle, so you're adding several cycles on the object.
You've to use "pause" and "resume".
Example bellow:
var cycleConfigured = false;
$(document).ready(function() {
$('.slideshow').hover(
function() {
if(cycleConfigured)
$(this).cycle('resume');
else
{
$(this).cycle({
fx: 'fade',
speed: 600,
timeout: 300,
pause: 0
});
cycleConfigured = true;
}
},
function(){
$(this).cycle('pause');
}
).trigger('hover');
});​
The variable cycleConfigured will be used to control our cycle plugin, to check if it was already instantiated. In alternative you can create it on $(document).ready() and then pause it like this:
$(document).ready(function() {
// configure the cycle plugin
$('.slideshow').cycle({
fx: 'fade',
speed: 600,
timeout: 300,
pause: 0
});
$('.slideshow').cycle('pause'); // pause it right away.
$('.slideshow').hover(
function() {
$(this).cycle('resume'); // start playing.
},
function(){
$(this).cycle('pause'); // pause the slideshow.
}
).trigger('hover');
});​
Then everything you need to do is use $(this).cycle('pause') on out and $(this).cycle('resume') on over.
Anything let me know.
