I've created a dialog to ask the user if he really want to proceed creating another file (text buffer). However, there is something with my approach that requires me to click twice at the button yes or at the button no.
What am I doing wrong?
The code for the specific function is:
def createnew ()
var Hello=new MessageDialog (null, Gtk.DialogFlags.MODAL,
Gtk.MessageType.INFO, Gtk.ButtonsType.YES_NO, "Hello world!")
Hello.format_secondary_text ("This will delete the contets. Are you sure?")
Hello.run ()
case Hello.run()
when ResponseType.YES
_view.buffer.set_text("")
Hello.destroy ()
when ResponseType.NO
Hello.destroy ()
The function is working fine otherwise.
You are calling Hello.run () twice. The fist time, you discard the result and the second time you use it for the case block.

I'm trying to build an add-in with similar behaviour like the comment system.
I select a part of text.
Press a button in my add-in. A card is created that links to that text.
I do something else, like write text on a different position.
When I press the card in my add-in, I'd like to jump back to the selected text (in point 1).
I studied the API, documentation. And learned that I could do something like that with Bindings. A contentcontrol might also be an option, although I noticed that you can't connect and eventhandler (it's in beta). I might need an eventhandler to track changes later.
Create binding (step 2)
Office.context.document.bindings.addFromSelectionAsync(Office.BindingType.Text, { id: 'MyBinding' }, (asyncResult) => {
if (asyncResult.status == Office.AsyncResultStatus.Failed) {
console.log('Action failed. Error: ' + asyncResult.error.message);
} else {
console.log('Added new binding with id: ' + asyncResult.value.id);
}
});
Works. Then I click somewhere else in my document, to continue with step 4.
View binding (step 4).
So I click the card and what to jump back to that text binding, with the binding selected.
I figured there are multiple ways.
Method #1
Use the Office.select function below logs the text contents of the binding. However, it doesn't select that text in the document.
Office.select("bindings#MyBinding").getDataAsync(function (asyncResult) {
if (asyncResult.status == Office.AsyncResultStatus.Failed) {
}
else {
console.log(asyncResult.value);
}
});
Method #2
Use the GoToById function to jump to the binding.
Office.context.document.goToByIdAsync("MyBinding", Office.GoToType.Binding, function (asyncResult) {
let val = asyncResult.value;
console.log(val);
});
This shows like a blue like frame around the text that was previously selected and puts the cursor at the start.
I'd prefer that I don't see that frame (no idea if that's possible) and I would like to the text selected.
There is the Office.GoToByIdOptions interface that mentions:
In Word: Office.SelectionMode.Selected selects all content in the binding.
I don't understand how pass that option in the function call though and I can't find an example. Can I use this interface to get the selection?
https://learn.microsoft.com/en-us/javascript/api/office/office.document?view=common-js-preview#office-office-document-gotobyidasync-member(1)
goToByIdAsync(id, goToType, options, callback)
If there are other ways to do this, I'd like to know that as well.
With some help I could figure it out. I learned that an Interface is just an object.
So in this case:
const options = {
selectionMode: Office.SelectionMode.Selected
};
Office.context.document.goToByIdAsync("MyBinding", Office.GoToType.Binding, options, function (asyncResult) {
console.log(asyncResult);
});
This gives the selected result.
Sure someone can provide a better answer than this, as it's unfamiliar territory for me, but...
When you create a Binding from the Selection in Word, you're going to get a Content Control anyway. So to avoid having something that looks like a content control with the blue box, you either have to modify the control's display or you have to find some other way to reference a region of your document. In the traditional Word Object model, you could use a bookmark, for example. But the office-js APIs do not seem very interested in them.
However, when you create a Binding, which is an Office object, you don't get immediate access to the Content Control's properties (since that's a Word object). So instead of creating the Binding then trying to modify the Content Control, you may be better off creating the Content Control then Binding to it.
Something like this:
async function markTarget() {
Word.run(async (context) => {
const cc = context.document.getSelection().insertContentControl();
// "Hidden" means you don't get the "Bounding Box"
// (blue box with Title), or the Start/End tag view
cc.appearance = "Hidden";
// Provide a Title so we have a Name to bind to
cc.title = "myCC";
// If you don't want users changing the content, you
// could uncomment the following line
//cc.cannotDelete = true;
return context.sync()
.then(
() => {
console.log("Content control inserted");
// Now create a binding using the named item
Office.context.document.bindings.addFromNamedItemAsync("myCC",
Office.BindingType.Text,
{ id: 'MyBinding' });
},
() => console.log("Content control insertion failed")
).then(
() => console.log("Added new binding"),
() => console.log("Binding creation failed")
)
});
}
So why not just create the ContentControl, name it, and then you should be able to select it later using its Title, right? Well, getting the "data" from a control is one thing. Actually selecting it doesn't seem straightforward in the API, whereas Selecting a Binding seems to be.
So this code is pretty similar to your approach, but adds the parameter to select the whole text. The syntax for that is really the same syntax as { id: 'MyBinding' } in the code you already have.
function selectTarget() {
Office.context.document.goToByIdAsync(
"MyBinding",
Office.GoToType.Binding,
{ selectionMode: Office.SelectionMode.Selected },
function(asyncResult) {
let val = asyncResult.value;
console.log(val);
}
);
}
Both the Binding and the ContentControl (and its Title) are persisted when you save/reopen the document. In this case, the Binding is persisted as a piece of XML that stores the type ("text"), name ("MyBinding") and a reference to the internal ID of the content control, which is a 32-bit number, although that is not immediately obvious when you look at the XML - in an example here, the Id Word stores for the ContentControl is -122165626, but "Office" stores the ID for the Binding as 4172801670, but that's because they are using the two different two's complement representations of the same number.
I've made an aplication with vala where at some point I have to process a lot of files. I've created a window to choose a folder and then I get the paths of files and make some proces on them.
I've added a progress bar to this window to show how many files have been processed but for some reason it remains always empty.
Code about window:
this.files_window = new Gtk.Window();
this.files_window.window_position = Gtk.WindowPosition.CENTER;
this.files_window.destroy.connect (Gtk.main_quit);
// VBox:
Gtk.Box vbox = new Gtk.Box (Gtk.Orientation.VERTICAL, 5);
this.files_window.add (vbox);
// Buttons to open and close
Gtk.Button cancel = new Gtk.Button.with_label ("Cancel");
Gtk.Button select = new Gtk.Button.with_label ("Select");
vbox.add (select);
vbox.add (cancel);
// proogress bar
this.progress_bar = new Gtk.ProgressBar();
vbox.add(this.progress_bar);
// conect select to method do_stuff
select.clicked.connect (do_stuff);
this.files_window.show_all ();
As you can see, I connect the button "select" to the method "do_stuff" where I get the paths of selected files and make some process.
I update correctlly the fraction of the progres bar because I've added some prints to know if the value is correct and it is. It's just that the windows is not refreshing, possibly because all the work it is doing with the process of the files. Here is the code about do_stuff() method:
// some proces to get paths of files in the list sfiles
double fraction = 0.0;
this.progress_bar.set_fraction (fraction);
int processed_files = 0;
foreach (string sfile in sfiles) {
do_some_proces_to_file(sfile);
processed_files += 1;
fraction = (double)processed_files/(double)sfiles.length;
this.progress_bar.set_fraction (fraction);
stdout.printf("Real fraction: %f\n", this.progress_bar.get_fraction());
}
The printf shows that the value of the progres bar is being updated but in the window the bar is always empty.
Am I missing something? Is it the correct way to do the progres bar? Should I made another thread to do the stuff?
As #nemequ says, your code is blocking the main loop thread (which handles both user input and scheduling/drawing widget updates), hence it the progress bar is not updated until the method completes.
Using a thread is one way solve the problem, however using threads can lead to a lot of bugs however since it can be difficult to make even simple interactions between threads safe.
An async method avoids this by interleaving the code with the other work being done by the main loop. An async version of your do_stuff() would be pretty straight-forward to write, simply declare it async and put a yield in the for loop somewhere:
public async void do_stuff() {
...
foreach (string sfile in sfiles) {
// all of this is as before
do_some_proces_to_file(sfile);
processed_files += 1;
fraction = (double)processed_files/(double)sfiles.length;
this.progress_bar.set_fraction (fraction);
// Schedule the method to resume when idle, then
// yield control back to the caller
Idle.add(do_stuff.callback);
yield;
}
}
You can then kick it off from your click handler by calling: do_stuff.begin().
Unless there is some relevant code you're not showing, you're blocking the main loop. One option would be to do everything in a thread, and use an idle callback to update the UI. The basic idea is something like:
new GLib.Thread<void*>("file-processor", () => {
foreach (string sfile in sfiles) {
/* do stuff */
GLib.Idle.add(() => {
/* Update progress */
return false;
});
}
return null;
});
Depending on your application you may need to add a mutex to avoid race conditions. You may also need to add some logic for canceling the operation.
A better option might be to use a GLib.ThreadPool. You'd still want to update the UI from an idle callback, but this would allow each task to execute in parallel, which could provide a significant speed-up.
If I were you I'd probably wrap it all up in an async function to keep the API tidy, but you don't really have to.
I need to select an element, send values to it, press tab and then send new values.
I can select the element and send values to it but am not being able to send TAB from my keyboard and then send new value.
I used ptor first but then it is being obsoleted, I now am trying to do same by using browser.key but its not working for me.
Please Help !
i wrote a snippet and tested it against google.de (not .com! maybe you have to adjust this) and when sending TAB the next element gets the focus (in this case it's the search button).
the snippet:
describe('Test', function () {
it('should browse to google', function () {
browser.ignoreSynchronization = true;
browser.driver.get('https://www.google.de');
expect(browser.getCurrentUrl()).toEqual('https://www.google.de/');
});
it('should unfocus the search field', function () {
var search = element(by.name('q'));
search.sendKeys(protractor.Key.TAB);
browser.sleep(3000); // 3s to take a look ;)
});
});
I understand that this is a probably a noob-ish question, but I've had no luck with the other threads I've found on the same topic.
I've devised a workaround to hack a views exposed filter to hide and show products with a stock count of "0". The exposed filter for the stock count (input#edit-stock) is hidden with CSS and inside a custom block is a link to manipulate the form and trigger the query (with ajax). This is working great, but with one exception - after resetting the form with the views-provided "reset" button, toggle() will not rebind properly to the link, and click won't fire the first time. Works fine on the 2nd click. I'm sure that the solution is very simple, but I'm at a loss..
How to rebind toggle() effectively?
Sorry, I'm unable to provide a live example. Many thanks for any input.
CUSTOM BLOCK:
<a id="toggle" href="#">exclude</a>
JQUERY:
$(document).ready(function () {
var include = function () {
$('input#edit-stock').attr('value', 0).submit();
$('a#toggle').html('include');
};
var exclude = function () {
$('input#edit-stock').attr('value', '').submit();
$('a#toggle').html('exclude');
};
$('a#toggle').toggle(include, exclude);
$('input#edit-reset').live('click', function (event) {
$('a#toggle').unbind('toggle').toggle(include, exclude).html('exclude');
});
});
if i get the problem right you need to reset the toggle. Why instead of unbind toggle and rebinding it you just don't simulate a click if the link is == to include?
$(document).ready(function () {
var include = function () {
$('input#edit-stock').attr('value', 0).submit();
$('a#toggle').html('include');
};
var exclude = function () {
$('input#edit-stock').attr('value', '').submit();
$('a#toggle').html('exclude');
};
$('a#toggle').toggle(include, exclude);
$('input#edit-reset').live('click', function (event) {
//if the link is include, click it so that it resets to exclude, else do nothing
if ($('a#toggle').html() == 'include'){
$('a#toggle').click();
}
});
});

I am having trouble identifying the particular value or ID of a submit button after it has been clicked and submitted using AJAX.
If I place the following code as a global function, it properly alerts the value of the button clicked:
$(":submit").live('click', function() {
alert($(this).val());
})
However, when I attempt to define the variable, I am unable to use that variable from within the success callback function:
$(":submit").live('click', function() {
var whichButton = $(this).val();
})
...
$("#applicant-form").validate({
function(form) {
$(form).ajaxSubmit({
...
success: alert(whichButton);
I have also tried placing the code in the submitHandler, but that doesn't work either.
In a somewhat related post, a user had suggested I place the following code:
$("#accordion .edit").click(function(){
window.lastButtonClicked = this;
});
...
submitHandler: function(){
var index_origin = $(window.lastButtonClicked).attr("name");
}
But I was not able to get that to get the value of the button clicked (it said that the value was undefined).
Any suggestions?
UPDATE: It might help if I provide more information about why I need to know which button is pressed. I have two kinds of submit buttons for each form in a multi-part form. I would like to do different things based on which button was clicked.
$(":submit").live('click', function() {
var whichButton = $(this).val();
})
The scope of whichbutton is inside of this anonymous function; you can't access it from elsewhere. A quick fix might be to declare whichbutton as a global variable but there's probably very few cases where you should do that. More context as to what it is you're trying to do would help, right now it just looks like you're trying to alert the button text on success after an ajax form submit.
