How to check if a given window is open in Xul?
I would like to check if a window is already openned in my desktop app. So if it is, I'll not open it again.
-- my attempt
I'm trying to accomplish this using the window title, so I get the list of windows from windowManager and check the title, but the getAttribute is not from an interface that I can query, it's from element, what interface should I use?
var windowManager = Components.classes['#mozilla.org/appshell/window-mediator;1'].getService(Components.interfaces.nsIWindowMediator);
var enum = windowManager.getXULWindowEnumerator(null);
while(enum.hasMoreElements()) {
var win = enum.getNext().QueryInterface(Components.interfaces[" WHICH INTERFACE TO PUT HERE? "]);
write("WINDOW TITLE = " + win.getAttribute("title"));
}
If you set a windowtype="myWindowType" attribute on your document's <window> element then you can just use windowMediator.getMostRecentWindow('myWindowType'); to see whether you already have one open.
var windowManager = Components.classes['#mozilla.org/appshell/window-mediator;1'].getService(Components.interfaces.nsIWindowMediator);
var enum = windowManager.getEnumerator(null);
while(enum.hasMoreElements()) {
var win = enum.getNext().QueryInterface( Components.interfaces.nsIDOMChromeWindow );
write("WINDOW TITLE = " + win.document.documentElement.getAttribute("title") );
}
if you are using getXULWindowEnumerator you should use Components.interfaces.nsIXULWindow
you probably could use the nsIDOMWindow attribute name if you open the windows your self because you set the name of the window in the open function. This is not visible to the user so you have a little more flexibility
var win = window.open( "chrome://myextension/content/about.xul",
"windowName", "chrome,centerscreen" );
write( "WINDOW NAME: " + win.name ); // Should now give WINDOW NAME: windowName
If you are leaving the window name blank it will open a new window every time. If you however use a window name (something else than "" ) it will create it if it does not exists, or load the new content in the already existing window with the name you have specified.
Which seems like almost what you want. Butt you could use name attribute to avoid the reload if you have to.
var openNewWindow = true;
var windowManager = Components.classes['#mozilla.org/appshell/window-mediator;1'].getService(Components.interfaces.nsIWindowMediator);
var enum = windowManager.getEnumerator(null);
while(enum.hasMoreElements()) {
var win = enum.getNext().QueryInterface( Components.interfaces.nsIDOMChromeWindow );
if( win.name == "windowName" ) {
openNewWindow = false;
}
}
if( openNewWindow ) {
var win = window.open( "chrome://myextension/content/about.xul",
"windowName", "chrome" );
}

I'm developing a sketch plugin. In the modal window I'm using to get user input there is a select. I can access the value of textField but I can't access value of the select.
Here is where I create the select:
var chooseFormatOptions = ['.png', '.jpg', '.pdf'];
var chooseFormatSelect = NSComboBox.alloc().initWithFrame(NSMakeRect(0, 250, viewWidth, 30));
chooseFormatSelect.addItemsWithObjectValues(chooseFormatOptions);
Here is where I try to get the combo box value
if (response == "1000"){
var projectName = projectField.stringValue();
var deviceName1 = firstDevicefield.stringValue();
var deviceDim1 = firstDimfield.stringValue();
var deviceName2 = secondDevicefield.stringValue();
var deviceDim2 = secondDimfield.stringValue();
var format = chooseFormatSelect.objectValues.indexOfSelectedItem(),
//var scale = chooseScaleOptions.stringValue();
//var pathOption = choosePathOptions.stringValue();
}
The error that it gives me when I run the plugin (if response == 1000) is: can't find variable chooseFormatSelect.
Do you know why I can get values of input fields (so it can find variables) but not that of the select one?
What about access text field 'text' variable while observing changes?
You may find this link helpfull (to add observe).
For NSComboBox follow this
Simply implement delegate then access value through following method
I'm successfully creating a Sharepoint List (named "XMLToPDFTestList"), which I can see via Site Actions > View All Site Content, but my attempts to add columns to the list has so far proven fruitless.
Here is how I'm trying to do it:
private void ProvisionallyCreateList()
{
SPWeb mySite = SPContext.Current.Web;
// Check to see if list already exists; if so, exit
if (mySite.Lists.TryGetList(listTitle) != null) return;
SPListCollection lists = mySite.Lists;
SPListTemplateType listTemplateType = new SPListTemplateType();
listTemplateType = SPListTemplateType.GenericList;
string listDescription = "This list is to hold inputted vals";
lists.Add(listTitle, listDescription, listTemplateType);
// Now add a couple of columns
SPList list = lists["XMLToPDFTestList"];
string faveNum = list.Fields.Add("favoriteNumber", SPFieldType.Text, false);
list.Fields[faveNum].Description = "favorite number";
list.Fields[faveNum].Update();
string faveCol = list.Fields.Add("favoriteColor", SPFieldType.Text, false);
list.Fields[faveCol].Description = "favorite color";
list.Fields[faveCol].Update();
}
This is all I see when I click "XMLToPDFTestList":
My "gut feeling" is that this line:
SPList list = lists["XMLToPDFTestList"];
...is not right/not specific enough. Instead of "XMLToPDFTestList" it should be something else/prepend something, or so. But what, exactly?
It was, as is so often the case, "my bad" (YMMV?).
The problem is in my list item creation code which, because I was not assigning anything to the default/inherited "Title" field, made it appear to me (as in the scream shot above) that no item was being added.
Once I fixed the code, by changing this:
private void SaveInputToList()
{
using (SPSite site = new SPSite(siteUrl))
{
using (SPWeb web = site.RootWeb)
{
SPList list = web.Lists[listTitle];
SPListItem SPListItemFaveNum = list.Items.Add();
SPListItemFaveNum["favoriteNumber"] = "7"; //inputtedNumber; TODO: Once 7 and teal are being saved and retrieved successfully, assign the var vals - will need to declare the controls created in CreateChildControls() globally
SPListItemFaveNum.Update();
SPListItem SPListItemFaveHue = list.Items.Add();
SPListItemFaveHue["favoriteColor"] = "teal";
SPListItemFaveHue.Update();
}
}
}
...to this:
private void SaveInputToList()
{
using (SPSite site = new SPSite(siteUrl))
{
using (SPWeb web = site.RootWeb)
{
SPList list = web.Lists[listTitle];
SPListItem spli = list.Items.Add();
spli["Title"] = "Write the Title";
spli["favoriteNumber"] = "7";
//SPListItemFaveNum.Update();
//SPListItem SPListItemFaveHue = list.Items.Add();
spli["favoriteColor"] = "teal";
//SPListItemFaveHue.Update();
spli.Update();
}
}
}
...it works fine: an item is added with all three values (Title, favoriteNumber, and favoriteColor).
I was assuming the item wasn't being created because "Title" was blank, and I was calling update on each SPListItem, whereas all I really need to do is call Update once, and on one SPListItem, not multiple.
I know this question has been asked a bunch of times, but none of the answers (or at least what i took away from them) was a help to my particiular problem.
I want to dynamically change a part of the variable path, so i don't have to repeat the same code x-times with just two characters changing.
Here's what i got:
In the beginning of my script, i'm setting the reference to PlayerData scripts, attached to the GameManager object like this:
var P1 : P1_Data;
var P2 : P2_Data;
function Start(){
P1 = GameObject.Find("GameManager").GetComponent.<P1_Data>();
P2 = GameObject.Find("GameManager").GetComponent.<P2_Data>();
}
Later, i want to access these scripts using the currentPlayer variable to dynamically adjust the path:
var currentPlayer : String = "P1"; //this actually happens along with some other stuff in the SwitchPlayers function, i just put it here for better understanding
if (currentPlayer.PlayerEnergy >= value){
// do stuff
}
As i was afraid, i got an error saying, that PlayerEnergy was not a part of UnityEngine.String.
So how do I get unity to read "currentPlayer" as part of the variable path?
Maybe some parse function I haven't found?
Or am I going down an entirely wrong road here?
Cheers
PS: I also tried putting the P1 and P2 variables into an array and access them like this:
if (PlayerData[CurrentPlayerInt].PlayerEnergy >= value){
// do stuff
}
to no success.
First of all,
var currentPlayer : String = "P1"
here P1 is just string, not the previous P1/P2 which are referenced to two scripts. So, if you want, you can change
currentPlayer.PlayerEnergy >= value
to
P1.PlayerEnergy >= value
or,
P2.PlayerEnergy >= value
But if you just want one function for them, like
currentPlayer.PlayerEnergy >= value
Then you have to first set currentPlayer to P1/P2 which I assume you are trying to do. You must have some codes that can verify which player is selected. Then, maybe this can help -
var playerSelected: int = 0;
var currentPlayerEnergy: int = 0;
.....
//Use your codes to verify which player is selected and then,
if (playerSelected == 1) {
currentPlayerEnergy = P1.PlayerEnergy;
} else if (playerSelected == 2) {
currentPlayerEnergy = P2.PlayerEnergy;
}
//Now use your favorite function
if (currentPlayerEnergy >= value) {
//Do stuff
}
As there was no reply providing the answer I needed, I'll share the solution that did the trick for me, provided by a fellow student.
Instead of having the PlayerData scripts pre-written, I generate them using a public class function in a Playermanager script. This generates the Playerdata as attached scripts, saved into an array.
I can then access them through Playermanager.Playerlist[Playernumber].targetvariable.
Which is what I wanted to do, only with the Playerdata being attached to a script instead of a gameobject. And it works great!
Here's the full code of my Playermanager Script:
//initialise max players
public var maxplayers : int = 2;
// Initialise Playerlist
static var Players = new List.<PlayerData>();
function Start () {
for (var i : int = 0; i < maxplayers; i++){
var Player = new PlayerData();
Players.Add(Player);
Players[i].PlayerName = "Player " + i;
}
DontDestroyOnLoad (transform.gameObject);
}
public class PlayerData {
public var PlayerName : String;
public var PlayerEnergy : int = 15;
public var Fleet : List.<GameObject> = new List.<GameObject>();
}
As you see, you can put any type of variable in this class.
I hope this helps some of you who have the same problem.

I have scrollableViews with a id name like idname1, idname2, idname88 etc. I want to destroy all widgets with a id name starting with "idname".
I have tried this:
var widgets = dijit.findWidgets("id^=divNodes");
dojo.forEach(widgets, function(w) {
w.destroyRecursive(false);
It seems that I cant use dijit.findWidgets("id^=divNodes") for this.
What will work for this?
From the docs...
registry.findWidgets returns an array of all non-nested widgets inside
the given DOM node.
https://dojotoolkit.org/reference-guide/1.8/dijit/registry.html
You could iterate over the registry yourself
require(["dojo/_base/array", "dijit/registry"], function(array, registry){
var startsWith = function(wholeString, lookFor) {
return wholeString.slice(0, lookFor.length) == lookFor}
};
var toDestroy = array.filter(registry.toArray(),
function(w) { return startsWith(w.id, 'divNodes'); });
array.forEach(toDestroy, function(w) { w.destroyRecursive(false); });
});
First, you have to know that I am developing my project with Struts (J2EE
Here is my problem :
I have 2 dijit.form.Select widgets in my page, and those Select are filled with the same list (returned by a Java class).
When I select an option in my 1st "Select widget", I would like to update my 2nd Select widget, and disable the selected options from my 1st widget (to prevent users to select the same item twice).
I succeed doing this (I'll show you my code later), but my problem is that when I open my 2nd list, even once, it will never be refreshed again. So I can play a long time with my 1st Select, and choose many other options, the only option disabled in my 2nd list is the first I've selected.
Here is my JS Code :
function removeSelectedOption(){
var list1 = dijit.byId("codeModif1");
var list2 = dijit.byId("codeModif2");
var list1SelectedOptionValue = list1.get("value");
if(list1SelectedOptionValue!= null){
list2.reset();
for(var i = 0; i < myListSize; i++){
// If the value of the current option = my selected option from list1
if(liste2.getOptions(i).value == list1SelectedOptionValue){
list2.getOptions(i).disabled = true;
} else {
list2.getOptions(i).disabled = false;
}
}
}
Thanks for your help

I think you have to reset() the Select after you've updated its options' properties. Something like:
function removeSelectedOption(value)
{
var list2 = dijit.byId("codeModif2"),
prev = list2.get('value');
for(var i = 0; i < myListSize; i++)
{
var opt = myList[i];
opt.disabled = opt.value === value;
list2.updateOption(opt);
}
list2.reset();
// Set selection again, unless it was the newly disabled one.
if(prev !== value) list2.set('value', prev);
};
(I'm assuming you have a myList containing the possible options here, and the accompanying myListSize.)
