How to use the Gtk ComboBox in gjs? - combobox

Following some PyGTK tutorials, I'm trying to fill a combo box in gjs (native javascript on the Gnome desktop)
So far I came up with two similar ways that both almost work.
The first one is probably closest to the example in the tutorial:
var testStore = new Gtk.ListStore ();
testStore.append ([0, "test1"]);
testStore.append ([1, "test2"]);
var cbox = Gtk.ComboBox.new_with_model (testStore);
cbox.set_entry_text_column (1);
cbox.show ();
Main problem here is that it doesn't display anything, eg the combobox is empty. According to the tutorial, the "new Gtk.ListStore" needs the column types as arguments, but anything I put there just caused some error messages.
Mixing it with codes from the other examples, I came up with this one:
var testStore = new Gtk.ListStore ();
testStore.append ([0, "test1"]);
testStore.append ([1, "test2"]);
var cbox = Gtk.ComboBox.new_with_model (testStore);
var cellRenderer = new Gtk.CellRendererText ();
cbox.pack_start (cellRenderer, true);
cbox.add_attribute (cellRenderer, "text", 1);
cbox.show ();
It has the advantage that it acutally displays something, eg the combobox is filled with list items that can be selected - but they're all empty. Just blocks of white in white.
Any ideas?

Maybe redundant, but works:
let model = new Gtk.ListStore();
model.set_column_types([GObject.TYPE_STRING, GObject.TYPE_STRING]);
let cbox = new Gtk.ComboBox({model: model});
let renderer = new Gtk.CellRendererText();
cbox.pack_start(renderer, true);
cbox.add_attribute(renderer, 'text', 1);
model.set(model.append(), [0, 1], ['key1', 'value1']);
model.set(model.append(), [0, 1], ['key2', 'value2']);
cbox.set_active(0); // set value
cbox.connect('changed', function(entry) {
let [success, iter] = cbox.get_active_iter();
if (!success)
return;
let myValue = model.get_value(iter, 0); // get value
});

Google Earth Engine: set Feature to FeatureCollection, but not a whole Array

I try to add a new Feature to the large Feature Collection, but with a function set() its override the whole list to each feature. But my purpose is to add each value from the array to the corresponding FeatureCollection. Can anybody help me?
var table = ee.FeatureCollection(ft:.....blablabla);
**//Create an Array from the property DN in the FeatureCollection:**
var propert = table.limit(100).aggregate_array('DN');
*// Values less than 1 will be set to 1, larger than 1== 0:*
var limit = ee.Array(propert).lt(1);
print(limit);
//Function, that add the list! of features (limit) to new property (Class) in the FeatureCollection ("table").
var addFeature = function(ar) {
return ar.set({Class: limit});
//Map throw the Featurecollection table
var areaAdded = table.limit(100).map(addArea);
};
So, if you can see, my code add the whole Array [limit] to each property in the FeatureCollection, not a first Value from the Array to the first property and so on...
Could anybody help me? thank you
If you have a smallish number of features, you can convert the feature collection to a list, convert the array to a list, zip() them together, map a function over the lists to set the property. Toy example:
var features = [
ee.Feature(ee.Geometry.Rectangle(30.01, 59.80, 30.59, 60.15), {name: 'Voronoi'}),
ee.Feature(ee.Geometry.Point(-73.96, 40.781), {name: 'Thiessen'}),
ee.Feature(ee.Geometry.Point(6.4806, 50.8012), {name: 'Dirichlet'})
];
var fromList = ee.FeatureCollection(features);
var array = ee.Array([2, 3, 5]);
var lists = fromList.toList(fromList.size()).zip(array.toList());
var features = ee.FeatureCollection(lists.map(function(l) {
return ee.Feature(ee.List(l).get(0)).set('foo', ee.List(l).get(1));
}));
print(features);

dragAndDrop NOT working on Chrome

I am trying to perform a Drag and Drop operation on our Angular application using Protractor Jasmine. I am able to get hold of the source item but as the test runs, the source element gets selected but nothing happens thereafter; the drag and drop operation does not take place. There are no errors shown in the console.
An interesting thing about the destination container is that the items dropped here can be resized as per user wish. Also, there is no clearly marked place/area in the destination container where the dragged item will get dropped! But the container does have an ID; though that has still not helped here.
Here is the code:
let dragAndDrop = require('html-dnd').code;
.
.
.
function dragAndDropListItems(fdIndex: number): void {
let dragElement = element.all(by.repeater('listDefinition in lists')).get(fdIndex); // Select the first repeater corresponding to the first List Item in the list
let dragElementh5 = dragElement.all(by.css('a')).get(0); // Select the first List Item
let printFD = dragElementh5.getText().then((text: string) => {
console.log(text); // Print the innerHTML text from the chosen List Item to the Console
});
let finalDrop = element.all(by.css('[id="dashboardContainerDiv"]')).get(0);
dragElement.click();
browser.actions().dragAndDrop(dragElement, finalDrop).perform();
};
I have tried using coordinate based DragNDrop operation as well but the same in every case.
Other tried options include:
//browser.executeScript(dragAndDrop, dragElement, finalDrop); // Perform the drag and drop operation
//browser.driver.actions().dragAndDrop(dragElement, finalDrop).perform();
//browser.actions().dragAndDrop(dragElement, { x: 400, y: 400 }).perform();
// browser.driver.actions().mouseDown(dragElement).mouseMove(finalDrop).mouseUp(finalDrop).perform();
Kindly suggest a solution to this issue.
#FlorentB. I have attached the Code with your scripts imported.
let JS_DRAG_DROP = require('./drag-drop.js');
function dragAndDropListItems(fdIndex: number): void {
/*
let source = driver.find_element_by_css_selector("#drag")
target = driver.find_element_by_css_selector("#drop")

*/
let target = element.all(by.css('[id="dashboardContainerDiv"]')).get(0);
//dragElement.click();
browser.executeScript(JS_DRAG_DROP, source, target); // Perform the drag and

Array whose each clip is linked to its equal clip of another array

Hello I apologize in advance for my question which I'm sure is pretty basic.
On a map are set 33 landmarks with an array calling a class in the library.
A second array defines the coordinates of those landmarks.
for (var i:uint = 0; i < 33; i++) {
mark[i] = new landMark();
landMarks.addChild(mark[i]);
mark[i].x = lmxy[i]['x'];
mark[i].y = lmxy[i]['y'];
}
var lmxy:Array = [{x:1620,y:880},{x:1850, y:1050},etc...];
So far so good, the landmarks show each in its right place.
The third array contains different legends supposed to show when a landmark is clicked.
So the landmark [1] should show the legend [1] and the landmark [31] the legend [31]
var lgd:Array = [lgdA, lgdB, etc... ];
var legends:MovieClip;
for (var j:uint=0;j<lgd.length;j++) {
legends = new lgd[j]();
legends.x = 300;legends.y = 170;
}
Edit cause obviously that was unclear :
I tried that in the loop to link the marks to the legends but I get an error :
mark[i].addEventListener(MouseEvent.CLICK, getLgd);
function getLgd(e:Event):void {stage.addChild (lgd[i]);}
Any help would be very welcome !
The problem is that the variable i doesn't have a definition. The only way for you to find out which of the landmarks were clicked is to find its index in the array, then you can add the legend that has the same index. Because the index isn't passed from the event listener, you need to use e which has the target property.
This should do the trick:
mark[i].addEventListener(MouseEvent.CLICK, getLgd);
function getLgd(e:Event):void
{
var i:int = mark.indexOf(e.target);
stage.addChild(lgd[i]);
}

Amcharts SerialChart multiple line graphs different category value member paths (Silverlight)

EDIT I rewrote my question to make it more understandable after the conversation below with Tony (thanks!).
GOAL Render multiple line graphs (let's say 2) in the same chart. The charts have different x/y value pairs. For one x-value, I do not know both y-values.
I am using Silverlight. The classes available for this are SerialChart and LineGraph. The data source for both graphs is the same and is set at the SerialChart level. The name of the property for the x-axis is also defined there for both graphs (CategoryValueMemberPath).
As suggested by the amCharts documentation, we need to create objects that have a property for the category axis (x-axis) and then one property per graph. Let's call them "Graph1" and "Graph2". So the data source looks something like this:
List<MyClass> data = new List<MyClass>()
{
new MyClass() { Category = 0.1, Graph1 = 0.14, Graph2 = ??? }
,new MyClass() { Category = 0.15, Graph1 = ???, Graph2 = 0.05 }
,new MyClass() { Category = 0.2, Graph1 = 0.35, Graph2 = ??? }
,new MyClass() { Category = 0.18, Graph1 = ???, Graph2 = 0.12 }
... and so on ...
}
PROBLEM What am I supposed to do about the "???" values? I do not have the actual value for that graph for that category value.
If I do not set a value, the default value of 0.0 is assumed and it draws a spike to the x-axis. If I set the previously known Graph1/Graph2 value, then it creates a horizontal connection where there is not supposed to be one. I am basically altering the graph which leads to a wrong result.
So how do I solve this? I am getting the feeling that amCharts do not support this scenario.
You need to add two 'value' axes, one in the X direction and one in the Y direction (imagine, like a bubble chart).
// AXES
// X
var xAxis = new AmCharts.ValueAxis();
xAxis.position = "bottom";
xAxis.gridAlpha = 0.1;
xAxis.autoGridCount = true;
chart.addValueAxis(xAxis);
// Y
var yAxis = new AmCharts.ValueAxis();
yAxis.position = "left";
yAxis.gridAlpha = 0.1;
yAxis.autoGridCount = true;
chart.addValueAxis(yAxis);
Merge all your data points into one array with a common X axis field name ('x' in my example) and for points on line 1, add a property of 'line1' with its value, and for points on line 2, add a property of 'line2'.
For example, your data would look like this:
var chartData = [
{x:0.1,line1:0.25},
{x:0.246,line1:0.342},
{x:0.12,line2:0.16},
{x:0.3,line2:0.485}
];
Then add a 'graph' for each line to your chart specifying where to get the value from in the object array.
// GRAPHS
var graph = new AmCharts.AmGraph();
graph.xField = "x";
graph.yField = "line1";
graph.lineAlpha = 1;
graph.lineColor = '#FF9E01';
chart.addGraph(graph);
var graph2 = new AmCharts.AmGraph();
graph2.xField = "x";
graph2.yField = "line2";
graph.lineAlpha = 1;
graph2.lineColor = '#9EFF01';
chart.addGraph(graph2);
I've put all this into a Fiddle for you - http://jsfiddle.net/64EWx/

Finding New and Updated Pages in EpiServer

I have a requirement to display lists of newly-created and updated pages in our Episerver intranet - say the last ten of each. I've tried using FindPagesWithCriteria but this returns no results. Here's the code I've tried:
PageDataCollection recentPages;
PropertyCriteriaCollection criteria;
PropertyCriteria upperBound;
PropertyCriteria lowerBound;
criteria = new PropertyCriteriaCollection();
upperBound = new PropertyCriteria();
upperBound.Condition = CompareCondition.LessThan;
upperBound.Type = PropertyDataType.Date;
upperBound.Value = DateTime.Today.ToString();
upperBound.Name = "Created"; // Or Saved for updated pages
criteria.Add(upperBound);
lowerBound = new PropertyCriteria();
lowerBound.Condition = CompareCondition.GreaterThan;
lowerBound.Type = PropertyDataType.Date;
lowerBound.Value = DateTime.Today.AddDays(-7).ToString();
lowerBound.Name = "Created";
criteria.Add(lowerBound);
recentPages = DataFactory.Instance.FindPagesWithCriteria(PageReference.StartPage, criteria);
I've also tried using the RecentlyChangedPagesFinder (as detailed here) - this returns some results, but when I try to use the set of results to build a PageCollection to databind into a PageList, again I get nothing output. And I can't see that I could use that for new pages, only updated ones.
The property name should be "PageCreated".
http://epiwiki.se/developing/properties/all-built-in-properties
You can also improve your FindPagesWithCriteria-syntax by going something like this:
var criterias = new PropertyCriteriaCollection
{
new PropertyCriteria()
{
Name = "SomeProp",
Type = PropertyDataType.PageType,
Value = "eh",
Condition = CompareCondition.Equal,
Required = true
},
new PropertyCriteria()
{
...
};
var pages = DataFactory.Instance.FindPagesWithCriteria(somePageLink, criterias);
