I have a relative simple CamanJS that is working well to add a layer, set it to a fill color and set the blending mode.
function changeColor(layer, hexCode) {
Caman(layer, function() {
this.greyscale();
this.contrast(-10);
this.newLayer(function () {
this.setBlendingMode("overlay");
this.fillColor(hexCode);
});
this.render();
});
};
changeColor('#paint','#ff0000');
function changeFilter(layer, hexCode) {
Caman(layer).revert(false);
changeColor(layer,hexCode);
};
However, I can't figure out how to change just one of the settings (fillColor) on that layer without reverting the image and starting over. Is this the best way to do it? Or can I just update the fillColor itself?

I am working with standalone (not mobile) and I think it is _getScroll method for reaching it.
how to implement it here qooxdoo selectbox example
I found similar for mobile implementing virtual scrolling list console.log says container._getScroll is not a function.
The idea is to get scrollbar from a widget, the scrollbar you are needed is NativeScrollbar of the widget qx.ui.list.List. Then add event handler for a "scroll" event. In handler u have to compare current position of scroll and maximum.
Try the code below (eg copy and paste into the Qooxdoo playground).
qx.Class.define("SelectBoxWithScrollEndEvent", {
extend: qx.ui.form.SelectBox,
construct: function(){
this.base(arguments);
this.__setupScroll();
},
events: {
"scrollEndHappened": "qx.event.type.Event"
},
members: {
__setupScroll: function(){
const list = this.getChildControl("list");
const scrollbar = list.getChildControl("scrollbar-y");
scrollbar.addListener("scroll", function(e){
if (scrollbar.getMaximum() === scrollbar.getPosition()){
this.fireEvent("scrollEndHappened");
}}, this);
}
}
});
const box = new SelectBoxWithScrollEndEvent();
const data = new qx.data.Array([1,2,3,4,5,1,2,3,4,5,1,2,3,4,5,1,2,3,4,5,1,2,3,4,5]);
const controller = new qx.data.controller.List(data, box);
box.addListener("scrollEndHappened", function(){
alert("SCROLL HAPPENED ALERT");
}, this);
this.getRoot().add(box);
I'm playing with the angular-leaflet-directive, and getting the marker names from a mouse click is straight forward. I just listen for the leafletDirectiveMarker.click event and then access args.markerName.
angular-leaflet-directive also works with markercluster, so I can cluster markers that have the same coordinates or ones that are close by. However, I would like to do the following, but it is not clear from the documentation on how to do it:
Make user double-click on cluster to zoom in. Currently doing a single click on a cluster will zoom in on the markers. see example.
How to listen for click event on cluster and get all marker names in the cluster.
The documentation for clustermarker has a cluster event:
markers.on('clusterclick', function (a) {
console.log('cluster ' + a.layer.getAllChildMarkers().length);
});
But I'm not sure what event I should be listening to using angular-leaflet-directive.
As far as your first question goes, you'll have to hook the doubleclick and pass it the fire('click') command after overriding the usual click event. Probably more trouble than its really worth, especially on mobile - and not something I can easily solve.
Regarding your second question, I have just solved it.
$scope.openMarker is a reference to an ng-click event in my jade template that is attached to an ng-repeat which pulls images and their id's from the database.
$scope.openMarker = function(id) {
var _this = [];
_this.id = id;
leafletData.getMarkers()
.then(function(markers) {
$scope.london = {
lat: $scope.markers[_this.id].lat,
lng: $scope.markers[_this.id].lng,
zoom: 19
};
var _markers = [];
_markers.currentMarker = markers[_this.id];
_markers.currentParent = _markers.currentMarker.__parent._group;
_markers.visibleParent = _markers.currentParent.getVisibleParent(markers[id]);
_markers.markers = markers;
return _markers;
}).then(function(_markers){
if (_markers.visibleParent !== null) {
_markers.visibleParent.fire('clusterclick');
} else {
_markers.currentMarker.fire('click');
}
return _markers;
}).then(function(_markers){
_markers.currentParent.zoomToShowLayer(_markers.markers[ _this.id ], function() {
$scope.hamburg = {
lat: $scope.markers[_this.id].lat,
lng: $scope.markers[_this.id].lng,
zoom: 19
};
if (_markers.currentMarker !== null) {
_markers.currentMarker.fire('click');
} else {
_markers.visibleParent.fire('clusterclick');
_markers.currentMarker.fire('click');
}
});
});
};
You can read more about how I came to this solution here at github.
Much like many people, I too had a long search with no results. While experimenting with another method, I came across this:
$timeout(function(){
leafletData.getLayers().then(function(layers) {
$scope.markerClusterGrp = layers.overlays.locations;
var clusters = $scope.markerClusterGrp.getLayers();
$scope.markerClusterGrp.on('clustermouseover', function (a) {
var clusterObjects = a.layer.getAllChildMarkers();
console.log(clusterObjects);
});
$scope.markerClusterGrp.on('clusterclick', function (a) {
var clusterObjects = a.layer.getAllChildMarkers();
console.log(clusterObjects);
});
});
},1000);
It works the same, the difference is that it requires a timeout in order to wait for the layer to render with all markers (my understanding, correct me if wrong :-) ).
I hope this helps anyone searching for an angular solution. Just remember to include $timeout in your controller dependencies.
I have an element that appears when the user clicks a button elsewhere on the screen. The element appears to come out of the top of the screen. The element by default needs to be tucked out of view above the screen, so I will have a margin-top style that is based on the height of the element (and will be a negative value). This cannot be hardcoded in css because the element height may vary. When I click the button, I want the element margin-top to change to 0 and I want a transition animation.
The sample shown on angularJS documentation is for adding a removing a class. This would work fine if I knew the values to be set and could code them in CSS, however I cannot. What is the correct way to solve this?
The code below works for displaying and hiding my element using a margin but there is no animation. How do I trigger an animation here when the margin changes?
https://docs.angularjs.org/guide/animations
Quote Total: {{salesPriceTotal + taxesTotal - tradeInsTotal | currency}}
<div class="totals" ng-style="setTopMargin()">
// totals stuff here.
</div>
$scope.setTopMargin = function() {
return {
marginTop: $scope.marginTop
}
};
$scope.$watch('showTotals', function() {
var margin = $scope.showTotals ? 10 : -160 + $scope.modelTotals.length * -200;
$scope.marginTop = margin.toString() + 'px';
});
I added the following code per a suggested solution, but this code is never hit.
myApp.animation('.totals', function () {
return {
move: function (element, done) {
element.css('opacity', 0);
jQuery(element).animate({
opacity: 1
}, done);
// optional onDone or onCancel callback
// function to handle any post-animation
// cleanup operations
return function (isCancelled) {
if (isCancelled) {
jQuery(element).stop();
}
}
},
}
});
As the documentation explains: "The same approach to animation can be used using JavaScript code (jQuery is used within to perform animations)".
So you basically needs to use animate() from jQuery to do what you want.
I am trying to integrate Sencha 4.1 (ExtJS) with the Leaflet mapping library while using Sencha Architect.
When the page loads, the tiles are mixed up and appear offset. I need to drag the page up to be able to see the tiles.
The full project is available here: https://github.com/breizo/SenchaLeaflet.
Here is an excerpt of the custom component created (see full code here: https://github.com/breizo/SenchaLeaflet/blob/master/ux/LeafletMap.js).
constructor: function () {
this.callParent(arguments);
this.on({
resize: 'doResize',
scope: this
});
var ll = window.L;
if (!ll) {
this.setHtml('Leaflet library is required');
}
}
onRender: function() {
this.callParent(arguments);
var renderTo = arguments[0].dom.id;
debugger;
var me = this,
ll = window.L,
element = me.mapContainer,
mapOptions = me.getMapOptions(),
map,
tileLayer;
if (ll) {
// if no center property is given -> use default position
if (!mapOptions.hasOwnProperty('center') || !(mapOptions.center instanceof ll.LatLng)) {
mapOptions.center = new ll.LatLng(47.36865, 8.539183); // default: Zuerich
}
me.setTileLayer(new ll.TileLayer(me.getTileLayerUrl(), me.getTileLayerOptions()));
tileLayer = me.getTileLayer();
mapOptions.layers = [tileLayer];
me.setMap(new ll.Map(renderTo, mapOptions));
map = me.getMap();
// track map events
map.on('zoomend', me.onZoomEnd, me);
map.on('movestart', me.onMoveStart, me);
map.on('moveend', me.onMoveEnd, me);
me.fireEvent('maprender', me, map, tileLayer);
}
},
When debugging it appears that when onRender is called, the parent container of the map is not properly sized yet, in particular its height is only enough to contain the attrib text, about 16 pix. WHen the doResize is called, the container is properly sized, but it doesn't change the end result: the tiles are mixed up and offset.
I tried various changes to the container, but nothing worked...
1) Problem with mixed layers is caused by CSS. Your leaflet.css has wrong path in html, so it's not attached in the document. To fix mixing issue set correct path to css file, or attach it from CDN:
<link rel="stylesheet" href="http://cdn.leafletjs.com/leaflet-0.4/leaflet.css" />
2) Wrong map offset is caused by extjs generated div:
<div class="x-llmap x-fit-item x-llmap-default" ...></div>
It pushes map container to the bottom and wrong offset calculations are made. You can also fix this using inline style or CSS:
.leaflet-map-pane {
top: 0;
}
I am a little desperate here. I have been reading everything I was able to find on Drupal.behaviours but obviously its still not enough. I try running a masonry grid with the infinitescroll plugin to attach the new images to the masonry. This works fine so far. The next thing I wanted to implement to my website is a hover effect (which shows information on the images) and later fancybox to show the images in a huger size.
(function ($) {
Drupal.behaviors.views_fluidgrid = {
attach: function (context) {
$('.views-fluidgrid-wrapper:not(.views-fluidgrid-processed)', context).addClass('views-fluidgrid-processed').each(function () {
// hide items while loading
var $this = $(this).css({opacity: 0}),
id = $(this).attr('id'),
settings = Drupal.settings.viewsFluidGrid[id];
$this.imagesLoaded(function() {
// show items after .imagesLoaded()
$this.animate({opacity: 1});
$this.masonry({
//the masonry settings
});
});
//implement the function of jquery.infinitescroll.min.js
$this.infinitescroll({
//the infinitescroll settings
},
//show new items and attach behaviours in callback
function(newElems) {
var newItems = $(newElems).css({opacity: 0});
$(newItems).imagesLoaded(function() {
$(newItems).animate({opacity: 1});
$this.masonry('appended', newItems);
Drupal.attachBehaviours(newItems);
});
});
});
}
};
})(jQuery);
Now I read that I need to Reattach the Drupal.behaviours if I want the hover event to also take place on the newly added content.
(function ($) {
Drupal.behaviors.imgOverlay = {
attach: function (context) {
var timeout;
$('.img_gallery').hover(function() {
$this = $(this);
timeout = setTimeout(change_opacity, 500);
}, reset_opacity);
function change_opacity() {
//set opacity to show the desired elements
}
function reset_opacity() {
clearTimeout(timeout);
//reset opacity to 0 on desired elements
}
}
};
})(jQuery)
Where do I now write the Drupal.attachBehaviours() to make it work actually? Or is there some other error I just dont see atm? I hope I wrote the question so that its understandable and maybe it also helps somebody else, since I experienced that there is no real "official" running Version of this combination in drupal 7.
Ok, the solution is actually pretty simple. When writing it correctly than it also runs. its of course not Drupal.attachBehaviours() but Drupal.attachBehaviors() . So this combination now works and I am finally relieved :).
