I am building a simple POC using famo.us. I would like to use the device view from the famo.us University lessons but when I write this code (slightly modified from what I found in the tutorials) nothing renders:
/*globals define*/
define(function(require, exports, module) {
// import dependencies
var Engine = require('famous/core/Engine');
var ImageSurface = require('famous/surfaces/ImageSurface');
var StateModifier = require('famous/modifiers/StateModifier');
var DeviceView = require('./DeviceView');
// create the main context
var mainContext = Engine.createContext();
// your app here
var logo = new ImageSurface({
size: [267, 102],
content: '/content/images/t-logo-black.png'
});
var logoModifier = new StateModifier({
origin: [0.5, 0.5]
});
var logoNode = mainContext.add(logoModifier);
logoNode.add(logo);
});
It appears that just adding the line var DeviceView = require('./DeviceView'); is what is causing the problem because just adding that one line to a working app seems to make everything not work that was working before. So I have 2 questions:
How do I make the require for DeviceView work
Is there a place I can go to find this sort error? Right now a blank screen is not very helpful. :)
Thank you!
Device view is not a currently an open source view. I have heard they are ridding a few bugs but it will be released soon.
Next time you see something not loading, be sure to check the directory, to ensure the file actually exists.
I have found debugging a bit tricky thus far using famous. Really for your problem, only the console would give you what you are looking for. In the case of a view, if it is not showing up how I expect, I often drop an id or class into the view, so it because searchable in the DOM.
Creating better debugging tools would add to the the long list of things famo.us is looking to build in the coming months. As an early adopter, it's a bit of a tough road.
Good Luck!
to make it work add this code:
//var DeviceView = require('DeviceView');
var View = require("famous/core/View");
in createDevice() function change :
device = new View(deviceOptions);
var deviceModifier = new StateModifier({
size: [300,400],
origin: [0.5, 0.5]
});
comment out any GlobalEvents.
That is a custom view made for the lessons which is not provided with the famous package for download. You could inspect the source code of the lessons page and try to discover the URL from that JS file... But I think it is not going to be so easy.

That part is because of error.. take a look at the link above

How to make django-leaflet render with canvas?
I checked on leaflet documentation that it should use preferCanvas but there are no manual in django leaflet that shows how to do it, while var map are hidden somewhere...
Any clue
Even if you don't have access to the preferCanvas option or the renderer option of the L.Map, you can still use the renderer option of individual vector layers.
Using this in django-less, vanilla javascript would look like:
var map = new L.Map('leaflet', { /* map options */ });
var myCanvasRenderer = L.canvas();
var circle = L.circleMarker([0, 0], {
radius: 30,
renderer: myCanvasRenderer
}).addTo(map);
var line = L.polyline([[60, 10],[20, 200]], {
renderer: myCanvasRenderer
}).addTo(map);
Make sure that you're creating the L.Canvas renderer once and reusing it in all your vector layers.
You can confirm this works by using the developer tools of your web browser and noting that there is a <canvas> element inside the Leaflet map container, but there is no <svg> element to be found:
You can see this example live over here.
I have implemented code as per the google SDK documentation line by line in my app, but still when I click on google sign in button app shifts to new view controller with webview with blank screen. Have tried multiple solution found here : GIDSignIn white screen on iOS 91. But no lucks with resolving the problem , have attached the screen shot for getting closer look about the screen.
Following are the pods that I'm using,
Running XCode 9.1, iOS 10.0 and later. Kindly request someone to help.
Update: View Hierarchy
Update: viewDidLoad's code:
GIDSignIn.sharedInstance().uiDelegate = self
if self.isChangePassword {
self.addSignInView()
}
else {
self.addSignUpView()
}
fileprivate func addSignInView() {
guard let signInEmailView: SignInEmailView = Bundle.main.loadNibNamed(NibNames.SignInEmailView.rawValue, owner: self, options: nil)?[0] as? SignInEmailView
else {
return
}
signInEmailView.delegate = self
gaManager.trackScreen(screenName: ScreenNames.SignIn.rawValue)
self.animateView(signInEmailView)
}
fileprivate func addSignInView() {
guard let signInEmailView: SignInEmailView = Bundle.main.loadNibNamed(NibNames.SignInEmailView.rawValue, owner: self, options: nil)?[0] as? SignInEmailView
else {
return
}
signInEmailView.delegate = self
gaManager.trackScreen(screenName: ScreenNames.SignIn.rawValue)
self.animateView(signInEmailView)
}
I have the same problem. I use the UIAlertView to confirm user really want to do authorization. It will show the blank screen. If I remove the UIAlertView and show the authorization view directly. It works fine.
The problem also show in the Dropbox authorization screen.
If you not use UIAlertView , please try to pass the top most controller

Hope this can do some help.
Finally after so many days found the problem. I was showing splash view from my appDelegate using refrence of UIWindow which was adding and removing an imgview as subview to the window. So it was somehow messing with the UINavigation's stack and my view controller was not getting any reference to the UINavigationController. After removing that code it's working just fine. Also came to the solution that, if I want to show splash screen, as I can't use UIWindow's reference, I have to add new VC and write my all navigation code there. #TedYu Thank you very much for the help. :)
Wondering if someone might help with another pair of eyes - as I am trying to work out why some of my Famo.us 'Views' are being displayed despite having an opacity StateModifier set to '0'.
Here is my code - My apologies for it not being standard - I have "Panels" instead of "Views" and a few other things..but happy to expand on the code if needed.
function _buildSidePanel() {
this._sidePanel = _createPanel.call(this);
this._sidePanel.setOptions(this.constructor.DEFAULT_OPTIONS.sideMenu);
this._sidePanel.position = this.cm(this.constructor.DEFAULT_OPTIONS.sideMenu.position);
this._container.add(this._sidePanel.position).add(this._sidePanel);
this._menuHolder = _createPanel.call(this); //My version of a View
this._menuHolder.setOptions(this.constructor.DEFAULT_OPTIONS.sideMenu.menuHolder);
// Create StateModifiers
this._menuHolder.position = this.cm({ align: [.5,.6], origin: [.5,.6], proportions: [.9,.8] });
this._menuHolder.fadeState = this.cm({ opacity: 0 });
this._menuHolder.sizeState = this.cm();
this._menuHolder.mC = new ModifierChain();
this._menuHolder.mC.addModifier(this._menuHolder.fadeState);
this._menuHolder.mC.addModifier(this._menuHolder.sizeState);
this._menuHolder.mC.addModifier(this._menuHolder.position);
/* Tried splitting it to just modifiers but getting the same thing
this._sidePanel._container.add(this._menuHolder.fadeState)
.add(this._menuHolder.sizeState)
.add(this._menuHolder.position)
.add(this._menuHolder);
*/
this._sidePanel._container.add(this._menuHolder.mC).add(this._menuHolder);
// this._menuHolder.fadeState.setOpacity(1,this.constructor.DEFAULT_OPTIONS.sideMenu.menuHolder.transition.in);
}
I have created a ModifierChain and added among other things an Opacity State of 0. When I add this and then add the modifier and 'View' to the container it displays the View even though the View has a StateModifier of '0' so should not be displayed.
The 'fadeState.setOpacity' command is meant to transition the fadeState to display the View but it is commented out, so the View should not be displayed.
I have this working in other areas so know the approach works. I am also (hopefully) not using the same variable names, so not using a StateModifier more than once. But still stuck as to why this is being displayed.
Any help or thoughts would be gratefully appreciated.
Thanks.
I need a select box with options and an on select / on change so i can populate a second select box.
My first instinct was to just create one using a surface with a click event and a renderController / scrollview to make my drop down appear. This works wonderfully except that if I leave and come back to the page the zindex of the scrollview breaks and it scrolls over the container size.
Its a bug I need to deal with but my other problem is that with the small Iphone screen size conventional drop downs just eat to much screen real-estate.
This stackoverflow famo.us: how to handle textbox.onchange events had some great hints on how to edit an InputSurface. I thought using that and looking at the code for a Surface I could do it but no luck.
Any Ideas on how to deal with the lack of a select surface?
You can access the value property from inside the callback function:
function SelectSurface(options) {
Surface.apply(this, arguments);
this.onchange = options.onchange;
this._superDeploy = Surface.prototype.deploy;
SelectSurface.prototype.elementType = 'select';
}
SelectSurface.prototype = Object.create(Surface.prototype);
SelectSurface.prototype.constructor = SelectSurface;
SelectSurface.prototype.deploy = function deploy(target) {
target.onchange = this.onchange;
this._superDeploy(target);
};
var regionSelector = new SelectSurface({
size:[140,40],
onchange: regionSelect(),
content: '<option disabled selected style="display:none;">REGION</option><option value="central">CENTRAL</option><option value="northern">NORTHERN</option><option value="pacific">PACIFIC</option><option value="southern">SOUTHERN</option><option value="western">WESTERN</option>',
});
var regionSelect = function(){
return function() {
alert(this.value);
}
};
Hello,
I wonder how do I change my mouse event
because I would like to X.Caption activates only when I right-clicked on it.
thank you very much
If I'm correct ( other contributors, don't be afraid to correct me ), you might have to edit the internals of XTK for your needs. XTK has the "controls" defined in X.event.js for it's event such as HoverEvent and PanEvent which are acquired from the Google Closure Library. You can look into the Google Closure Library more as I haven't completely reviewed it, but X.caption is mostly derived from Goog.ui.Tooltip which can be used with the events from Goog.ui.Popup, Goog.ui.PopupBase, and Goog.events. You can try to include Goog.events into your Javascript and define your own click event or something related to that and look through the Google Closure Library some more.
If what I just wrote in the small paragraph above is not completely correct or anything like that, there are of course basic Javascript DOM Events for clicking. I'm not quite sure how those would work with XTK because XTK uses WebGL for rendering. You can review the basic events at http://www.w3schools.com/jsref/dom_obj_event.asp. If you find any solution for yourself, you are more than welcome to contribute it to XTK.
I think there are too ways no ? Change the xtk source code and compile your own version or something like this :
window.onload = function() {
myrenderer.config.HOVERING_ENABLED = false; // disabling show caption on mousehover
var mouse_x, mouse_y;
myrenderer.interactor.onMouseMove = function(event) {
mouse_x = event.offsetX;
mouse_y = event.offsetY;
}
myrenderer.interactor.onMouseDown = function(left,middle, right) {
if (right) {
var picked_id = myrenderer.pick(mouse_x, mouse_y);
if (picked_id==-1) throw new Error("No object");
var picked_object = myrenderer.get(picked_id);
var mycontainer = myrenderer.container;
var caption = new X.caption(mycontainer,mycontainer.offsetLeft + mouse_x + 10, mycontainer.offsetTop + mouse_y + 10,myrenderer.interactor);
caption.setHtml(picked_object.caption);
// use settimeout or something else to destroy the caption
}
}
}
The following JSFiddle shows how to do that. To actually display a tooltip etc. you can use any JS Library like jQuery UI.
