In particular mixing macros with SystemVerilog style of description.</p>\n\n<p>Is there a way how to accomplish the same task directly in the package?</p>\n"},{"Classification":"","Title":"How to download the screenshot automatically by using html2Canvas","Body":"<p>I have a canvas which shows a graph and I'm trying to take a screenshot of the canvas using html2canvas() with the code below :</p>\n\n<pre><code><div class=\"chartContainer\" id=\"chart1\"></div>\n<div id=\"displayCanvas\" style=\"display:none;\" class=\"stx-dialog\"></div>\n\nhtml2canvas($('#chart1'),{onrendered:function(canvas1) \n{$('#displayCanvas').append(canvas1)}});\n</code></pre>\n\n<p>Here when the chart container is loaded the it uses the div with the id \"displayCanvas\" and appends the screenshot of the canvas.</p>\n\n<p><strong>How can I download the screenshot of the canvas which is displayed?</strong> \nI have already tried using something like below to download the image: </p>\n\n<pre><code>var link = document.createElement('a');\nlink.download = stx.chart.symbol+\".png\";\nlink.href = stx.chart.canvas.toDataURL(\"png\");\nlink.click();\n</code></pre>\n\n<p>but it only downloads the data on the canvas as an image without the background (it does not download the screenshot but only the data) which when opened after downloading shows a black screen with data in it.

It is filled with constructs like this Firestore example (taken from <a href=\"https://firebase.google.com/docs/firestore/manage-data/delete-data\" rel=\"nofollow noreferrer\">here</a>):</p>\n\n<pre><code>db.collection(\"cities\").document(\"DC\")\n .delete()\n .addOnSuccessListener(new OnSuccessListener<Void>() {\n @Override\n public void onSuccess(Void aVoid) {\n Log.d(TAG, \"DocumentSnapshot successfully deleted!\");\n }\n })\n .addOnFailureListener(new OnFailureListener() {\n @Override\n public void onFailure(@NonNull Exception e) {\n Log.w(TAG, \"Error deleting document\", e);\n }\n });\n</code></pre>\n\n<p>or this Firebase auth example (from <a href=\"https://firebase.google.com/docs/auth/android/firebaseui\" rel=\"nofollow noreferrer\">here</a>):</p>\n\n<pre><code>AuthUI.getInstance()\n .signOut(this)\n .addOnCompleteListener(new OnCompleteListener<Void>() {\n public void onComplete(@NonNull Task<Void> task) {\n // ...\n }\n });\n</code></pre>\n\n<p>Google's own sample code and apps are full of such callbacks (usually assigned as listeners to <a href=\"https://developers.google.com/android/reference/com/google/android/gms/tasks/Task\" rel=\"nofollow noreferrer\"><code>Task</code></a> objects), always coded directly in an activity or fragment.</p>\n\n<p>For iOS and web programming, such a callback-based API is really nice. It would be nice for Android as well, except that it seems to be contrary to Google's own guidance on dealing with activity (and fragment) lifecycles. Specifically, the calls to API methods like <code>delete()</code> or <code>signOut()</code> operate asynchronously. The call-back objects passed as listeners will be retained until the associated task completes and the call-back is invoked. If the activity (or fragment) is destroyed and then recreated (say, by a configuration change) while the task is executing, the callback will be invoked on a stale object. The callback also retains a reference to the destroyed activity, causing a memory leak.</p>\n\n<p>How are we supposed to handle these callbacks? For observing queries, Google suggests using <code>LiveData</code> objects (as in <a href=\"https://firebase.googleblog.com/2017/12/using-android-architecture-components.html\" rel=\"nofollow noreferrer\">this blog post</a>). However, for many Firebase tasks (such as the two examples above), using <code>LiveData</code> doesn't make much sense. Are we just supposed to code all these calls in retained fragments or in services? That doesn't seem very workable. On the other hand, perhaps it's the only reasonable thing to do (considering that <code>Task</code> objects don't have any way to remove listeners once they've been added).</p>\n"},{"Classification":"","Title":"Accessing IIFE function variables","Body":"<p>I have a function defined and executed as such .. </p>\n\n<pre><code>var exitPopup = (function($) {\n var someVar = false;\n var someFunc = function() { doSomething(); };\n})(jQuery);\n</code></pre>\n\n<p>My question is, is it possible to access the variables and functions within?

When the user expands the Accordions (inside the ComponentGroup), the list of Toggle Buttons (inside the Accordions) is long and it doesn't fit in the screen.</p>\n\n<p>The problem is that the Form (occupied by ComponentGroup + Accordions + Toggle Buttons) is not scrollable, I suppose because there is an ambiguity of the meaning of the touching (that could be for selecting an item of the list or to do the scrolling). But, I suppose that in the users' mind there isn't true ambiguity: if the user does a simple tap, then he/she are selecting an item; if the user does a tap and then move the finger without stopping tapping, then he/she are trying to do a scrolling. I suppose that this is the expected behavior in the users' mind... otherwise, if the main ComponentGroup occupies all the screen, the scrolling becomes impossible (that is my case).</p>\n\n<p>At the moment, I found a partial unsatisfying solution adding some millimeters of padding to the main ComponentGroup, so there is few space on the borders of the screen to do the scrolling.

An API gateway microservice takes a request from front-end, publishes its message into the queue. Then a \"consumer\" microservice sends the result of the consumed message to the front-end.\nWhat's a good way to give back the result of user action in this case?\nIf we set up a websocket session to take such responses for example, the code to initiate user action and the code to give feedback for user action would end up being completely separate, although it happens in the same user workflow.

For context - I'm developing a music app, which will have multiple \"scenes\", which each include collections of \"tracks\" (similiar to Ableton Live). </p>\n\n<p>Here's my getter:</p>\n\n<pre><code> newTrack: state => {\n let newTrack = JSON.parse(JSON.stringify(state.newTrackDefaults))\n return newTrack\n },\n</code></pre>\n\n<p>Here's the object it refers to:</p>\n\n<pre><code> newTrackDefaults: {\n tune: [],\n // and other properties\n },\n</code></pre>\n\n<p>And then it is called by an action:</p>\n\n<pre><code> setUpNewScene: context => {\n let newScene = JSON.parse(JSON.stringify(context.state.newSceneDefaults))\n let newTrack = context.getters.newTrack \n console.log(newTrack) // this reveals that the problem is from the getter \n newScene.tracks.push(newTrack)\n context.commit('addNewScene', newScene)\n }\n</code></pre>\n\n<p>So the problem with this code is, when I add items (pitch-references) to a track on the first scene, then added a new scene, the <em>new</em> scene automatically receives the same track as the <em>first</em> scene. This is reflected in the Vuex state (according to the DevTool), not just the rendering. Also, when the tracks on the first scene are updated by the user, the tracks on the new scene change accordingly. So instinctively, this feels like a pass-by-reference type of error.</p>\n\n<p>Through various <code>console.log</code> experiments, I found that the getter was returning the \"filled\" track. It's fixable by skipping the getter and writing the action as: </p>\n\n<pre><code> setUpNewScene: context => {\n let newScene = JSON.parse(JSON.stringify(context.state.newSceneDefaults))\n let newTrack = JSON.parse(JSON.stringify(context.state.newTrackDefaults))\n console.log(newTrack) // this works fine\n newScene.tracks.push(newTrack)\n context.commit('addNewScene', newScene)\n }\n</code></pre>\n\n<p>... so though I have a fix, I'm puzzled as to the original behavior. Would the getter interfere with the <code>JSON</code> functions?
