I'm trying to access command line from a simple Dashboard Widget on Snow Leopard. My intention is to fill the contents of the widget from a command-line script I call. This should be possible.
I'm calling the script every time the widget is shown using it's onshow callback:
if (window.widget) {
widget.onshow = onshow;
}
function onshow() {
document.getElementById("mydynamicarea").innerHTML = widget.system("/usr/bin/id -un", null).outputString;
}
Above I'm trying to use just a simple command showing my username to test the command-line access. This doesn't work, the widget shows just the static text which I have on the HTML:
<div id="mydynamicarea">No data available</div>
The same Javascript works if I use a static string instead of the widget.system call:
if (window.widget) {
widget.onshow = onshow;
}
function onshow() {
document.getElementById("mydynamicarea").innerHTML = "This text is actually shown on widget";
}
When I look at the Console, I can see this error-message:
TypeError: Result of expression 'widget.system' [undefined] is not a function.
I have configured the command-line access in info.plist:
<key>AllowSystem</key>
<true/>
Any idea what I'm doing wrong?
killall DashboardClient
helped for me
There seems to be some bug in Dashboard. I managed to make the Widget work by renaming it. The widget worked just fine in Dashcode before renaming (thanks, Till Theis) and when I installed it from there with another name it worked. That inspired me to just trying to rename it and that worked as well.

I implemented Shepherd in my Vaadin Project, so i can guide users in tours through my web application.
But, i need to get access from the javascript on the Accordion Components in Vaadin, to open or close specific tabs. For this, i need to have access on the open() and close() method for the Accordion Components. So how can i access them through Javascript?
Already seen the Tutorial on the Website of them:
Vaadin calling java from javascript,
but sadly nothing over there, what could help me.
I already tried to use something like this:
UI.getCurrent().getPage().executeJs("window.startTour($0, $1)", this, Accordion1.getElement());
But when i try to bind it in javascript through:
window.startTour = (element, accordion) => { ... }
and in this window:
beforeShowPromise: function () {
return new Promise(function(resolve) {
element.$server.openAccordion(accordion.$server, 1);
resolve();
});
},
with the following method in java:
#SuppressWarnings("unused")
#ClientCallable
public void openAccordion(Object object, int index) {
Accordion accordion = (Accordion) object.get(this);
accordion.open(index);
}
i only get the following error message:
Class '...' has the method 'openAccordion' whose parameter 0 refers to unsupported type 'java.lang.Object'
No matter what i use as first parameter, everythin that extends Object doesnt work and i dont know why.
I found a recent post with the same question, but it was not helpful for me:
Unable to send a new bean instance to the server
Im using Intellij and in my Project: Java, Spring, Vaadin and Shepherd
Already tried to use different parameters, but only the int parameter is working, Object doesnt work.
The Problem is, i cant change the opened Tab of the Accordion from the Javascript over the Java, because of this error, so i have to implement for each Accordion 2 methods to open and close it.
Maybe somebody can help me with it or knows some tricks to master this.
Thanks
When using #ClientCallable you can pass only json or primitive types from JavaScript call to server. There is a real systems boundary here. Object is not supported and furthermore, you can cast that parameter to Java object.
I'm new to typescript and I'm trying to use a bit of code I found online to change links to look nice for my site,
<script src="https://wow.zamimg.com/widgets/power.js"></script>
<script>var wowhead_tooltips = {
"colorlinks": true,
"iconizelinks": true,
"renamelinks": true
};
</script>
I included that into my index.html, and it works great, until I load a component, I spent a lot of time looking around and found that I need to call $WowheadPower.refreshLinks();
To get the links to change when a new element is added, I wasn't sure how to declare that variable in typescript so I could tie it to various angular commands I wanted to do, unless I add it in a try catch:
loadScript(){
try{
// update tooltips
if(typeof $WowheadPower == 'undefined'){
$.getScript('//wow.zamimg.com/widgets/power.js');
} else {
$WowheadPower.refreshLinks();
console.log($WowheadPower)
}
} finally {}
}
I get an error that says
Cannot find name '$WowheadPower'
but I saved it anyway, and somehow on my page it works as I want it too.
It works perfect, but I still got the error so I declared it
try{
// update tooltips
var $WowheadPower
if(typeof $WowheadPower == 'undefined'){
$.getScript('//wow.zamimg.com/widgets/power.js');
} else {
$ WowheadPower.refreshLinks();
console.log($WowheadPower)
}
} finally {}
and it broke, I assume because I overwrote the correctly variable that has the right method.
Now I have to leave the error in to get functionality, but the error stops me from compiling when I ng serve. Until I hit save on VScode then it works fine again.
Any thoughts on how to resolve this?
since $WowheadPower is an external variable imported from another file, you can tell typescript that it exists without explicitly declaring it:
declare var $WowheadPower: any
write this at the beginning of your code so you tell TS that this variable exists. Ideally, you would write an interface that correctly defines $WowheadPower's type instead of any there.
I need to run some client-side javascript from a button in a form view in Odoo 8. This button runs a python method which returns this dictionary:
{"type": "ir.actions.client",
"tag": "my_module.do_something",}
do_something is defined in a .js file as follows:
openerp.my_module = function (instance) {
instance.web.client_actions.add("my_module.do_something", "instance.my_module.Action");
instance.my_module.Action = instance.web.Widget.extend({
init: function() {
// Do a lot of nice things here
}
});
};
Now, the javascript is loaded and executed properly, but even before launching the init function, Odoo loads a brand new, blank view, and once the javascript is over I can't get browse any other menu entry. In fact, wherever I click I get this error:
Uncaught TypeError: Cannot read property 'callbackList' of undefined
What I need instead is to run the javascript from the form view where the button belongs, without loading a new view, so both getting the javascript stuff done and leaving all callbacks and the whole environment in a good state. My gut feeling is that I shouldn't override the init funcion (or maybe the whole thing is broken, I'm quite new to Odoo client-side js) , but I couldn't find docs neither a good example to call js the way I want. Any idea to get that?
Sorry, I don't work on v8 since a lot of time and I don't remember how to add that, but this might help you: https://github.com/odoo/odoo/blob/8.0/doc/howtos/web.rst
Plus, if you search into v8 code base you can find some occurence of client actions in web module docs https://github.com/odoo/odoo/search?utf8=%E2%9C%93&q=instance.web.client_actions.add
Thanks to the pointers simahawk posted in another answer, I have been able to fix my js, which is now doing exactly what I needed. For your reference, the code is as follows:
openerp.my_module = function (instance) {
instance.web.client_actions.add("my_module.do_something", "instance.my_module.action");
instance.my_module.action = function (parent, action) {
// Do a lot of nice things here
}
};
I am trying to implement the displaying of a web page in Qt. I chose to use the Qt WebEngine to achieve my task. Here's what I did :
Wrote a sample web page consisting of a empty form.
Wrote a JS file with just an API to create a radio button inside the form.
In my code, it looks like this :
View = new QWebEngineView(this);
// read the js file using qfile
file.open("path to jsFile");
myJsApi = file.Readall();
View->page()->runjavascript (myjsapi);
View->page()->runjavascript ("createRadioButton(\"button1\");");
I find that the runJavaScript() function has no effect on the web page. I can see the web page in the output window, but the radio button I expected is not present. What am I doing wrong?
I think you will have to connect the signal loadFinished(bool) of your page() to a slot, then execute runJavaScript() in this slot.
void yourClass::mainFunction()
{
View = new QWebEngineView(this);
connect( View->page(), SIGNAL(loadFinished(bool)), this, SLOT(slotForRunJS(bool)));
}
void yourClass::slotForRunJS(bool ok)
{
// read the js file using qfile
file.open("path to jsFile");
myJsApi = file.Readall();
View->page()->runJavaScript(myjsapi);
View->page()->runJavaScript("createRadioButton(\"button1\");");
}
I had this problem, runJavascript didn't have any effect. I had to put some html content into the view (with page().setHtml("") before running it.
Check the application output, it might contain JavaScript errors. Even if your JS code is valid, you might encounter the situation where the script is run before DOMContentLoaded event, that is document.readyState == 'loading'. Therefore, the DOM might not be available yet, as well as variables or functions provided by other scripts. If you depend on them for your code to run, when you detect this readyState, either wait for the event or try calling the function later, after a timeout. The second approach with timeout might be needed if you need to get the result of the code execution, as this can be done only synchronously.
im creating a platform to user automated tests to verify if a widget is functional. I already made the tutorials and the saw the examples but still i can figure out what's happening.
the widget that im trying to test is made with iframes without src attribute and with im trying to find a element inside of that iframe without src attribute.`define(function (require) {
var registerSuite = require('intern!object');
var assert = require('intern/chai!assert');
registerSuite({
name: 'index',
'greeting form': function () {
return this.remote
.get(require.toUrl('localhost:3000'))
.findById('iframeId')
.switchToFrame('iframeId')
.findById('buttonID');
}
});
});`
With this code it happens that the intern runner returns a error saying that it wasn't unable to find the element. But when i try to run the same code on a iframe with a "src" attribute it finds the correct element and doesn't returns any error.
anyone could help ??
In the above code, you should clear the search context before trying to find an element in the iframe, like:
return this.remote
.get(require.toUrl('localhost:3000'))
.findById('iframeId')
.end()
.switchToFrame('iframeId')
.findById('buttonID')
This is assuming the findById call is to wait for the iframe to be added to the page. If you don't need to do that, just leave out the findById('iframeId') call and you should be good.
