I was just wondering if we have a specific library or framework built on the closure-library , which is specifically designed for touch devices(Android or Ipad). I already have my web-app using the closure-library, now want to maintain consistency for the mobile touch devices or tablets.
There are many other frameworks or plugins for other libraries like:
http://www.sencha.com/products/touch/ -- (Ext.js)
http://jqtouch.com/ -- (jquery)
Do we have something similar for the closure-library.
Can somebody please help me on this.
As far as I know the plain TOUCH events are already defined
/**
* Constants for event names.
* #enum {string}
*/
goog.events.EventType = {
...
// WebKit touch events.
TOUCHSTART: 'touchstart',
TOUCHMOVE: 'touchmove',
TOUCHEND: 'touchend',
TOUCHCANCEL: 'touchcancel',
}
But there is no gesture-recognizer.
If you use the gestures Webkit(Safari) fires, you will have to create your own externs file.
https://developer.apple.com/library/iad/documentation/UserExperience/Reference/GestureEventClassReference/index.html#//apple_ref/javascript/cl/GestureEvent
If you download the touch library from jQueryMobile's site. Just build jQueryMobile only with their touch library. Import that into your project. Then have a map like I did...
var hasTouch = 'ontouchstart' in window;
var humanEvents = {
DOWN: (hasTouch) ? goog.events.EventType.TOUCHSTART : goog.events.EventType.MOUSEDOWN,
OVER: (hasTouch) ? goog.events.EventType.TOUCHSTART : goog.events.EventType.MOUSEOVER,
MOVE: (hasTouch) ? goog.events.EventType.TOUCHMOVE : goog.events.EventType.MOUSEMOVE,
UP: (hasTouch) ? goog.events.EventType.TOUCHEND : goog.events.EventType.MOUSEUP,
OUT: (hasTouch) ? goog.events.EventType.TOUCHEND : goog.events.EventType.MOUSEOUT,
CLICK: (hasTouch) ? "tap" : goog.events.EventType.CLICK
};

I've seen various answers to this question for older versions but not sure how to translate to MAUI. The question being, is there a way that you can minimize the soft keyboard on a device from the Text Completed event of an Entry control?
I finally figured out how to do this. This solution is for Android only right now. It doesn't use a custom handler since I could not get the window token from PlatformView. Instead the code looks like this:
#if ANDROID
var imm = (Android.Views.InputMethods.InputMethodManager)MauiApplication.Current.GetSystemService(Android.Content.Context.InputMethodService);
if (imm != null)
{
//this stuff came from here: https://www.syncfusion.com/kb/12559/how-to-hide-the-keyboard-when-scrolling-in-xamarin-forms-listview-sflistview
var activity = Microsoft.Maui.ApplicationModel.Platform.CurrentActivity;
Android.OS.IBinder wToken = activity.CurrentFocus?.WindowToken;
imm.HideSoftInputFromWindow(wToken, 0);
}
#endif
So credit to the syncfusion folks that published their version, and this code above is modified from that to work in MAUI.
The code belongs in a custom handler. Based on Customize a control with a mapper.
In that Maui handler, handler.PlatformView is the Android control. Xamarin.Android properties/methods would be on that.
Something like:
using Microsoft.Maui.Platform;
namespace CustomizeHandlersDemo;
public partial class CustomizeEntryPage : ContentPage
{
public CustomizeEntryPage()
{
InitializeComponent();
ModifyEntry();
}
void ModifyEntry()
{
Microsoft.Maui.Handlers.EntryHandler.Mapper.AppendToMapping(
"MyCustomization", (handler, view) =>
{
#if ANDROID
handler.PlatformView....
#elif IOS
#elif WINDOWS
#endif
});
}
}
NOTE: That example modifies ALL Entries.
If you want to modify only SOME Entries, you instead define a subclass (e.g. public class MyEntry : Entry {}), and do this:
Microsoft.Maui.Handlers.EntryHandler.Mapper.AppendToMapping(
"MyEntryCustomizationOrWhatever", (handler, view) =>
{
if (view is MyEntry)
{
#if ANDROID
handler.PlatformView....
#elif IOS
#elif WINDOWS
#endif
}
});
For your specific situation, the line you were having trouble adapting to Maui contains btnSignIn.WindowToken.
Replace that with handler.PlatformView.WindowToken.
I want to set a minimum and a maximum zoom level in my map.
My first idea was to listen to 'zoomstart' events, but the org.gwtopenmaps.openlayers.client.Map class doesn't implement any listener with such event type. Then I tried to listen to 'zoomend' events. My idea was to check the zoomlevel after the zoom event and if it is higher/lower than a threshold value than i zoom to that threshold value. Example code:
#Override
public void onMapZoom(MapZoomEvent eventObject) {
if (eventObject.getSource().getZoom() > 18) {
eventObject.getSource().zoomTo(18);
}
}
But i found, the zoomTo event doesn't fire in this case. Has anybody got a solution to this problem?
Great idea Imreking.
I have added this to the GWT-Openlayers library.
So if you download the latest version from github now you can do :
map.setMinMaxZoomLevel(6, 8);
And you no longer need some javascript method in your own code.
I actually also added a showcase but having difficulties uploading it to our website.
Uploading the new showcase has now succeeded.
See http://demo.gwt-openlayers.org/gwt_ol_showcase/GwtOpenLayersShowcase.html?example=Min%20max%20zoom%20example to see an example of newly added Map.setMinMaxZoomLevel(minZoom, maxZoom).
I don't think this is possible in OpenLayers (normal and GWT).
According to me two solutions are available.
Option 1
This is ugly for the user. As he sees the map getting zoomed, and just after this going back to the previous zoomlevel.
The Timer is needed to give OL the chance to animate the zoom.
map.addMapZoomListener(new MapZoomListener()
{
#Override
public void onMapZoom(final MapZoomEvent eventObject)
{
Timer t = new Timer()
{
#Override
public void run()
{
if (eventObject.getSource().getZoom() > 15)
{
map.zoomTo(15);
}
else if (eventObject.getSource().getZoom() < 10)
{
map.zoomTo(10);
}
}
};
t.schedule(500);
}
});
Option 2
Don't use the zoom default zoom control but create your own zoom buttons (using normal GWT), and putting these on top of the map. If you want you can style these buttons in the same way as the normal buttons. The trick 'create in normal GWT, and make it look like OL' is a trick I use a lot (for example to create a much more advanced layer switcher).
Note : I am one of the developers of GWT-OpenLayers, if you want I can add an example to our showcase displaying how to do 'Option 2'.
Knarf, thank you for your reply. I tried the 'Option 1' and it worked, but i found another solution which is maybe more acceptable for the users.
My solution is:
map.isValidZoomLevel = function(zoomLevel) {
return ((zoomLevel != null) &&
(zoomLevel >= minZoomLevel) &&
(zoomLevel <= maxZoomLevel) &&
(zoomLevel < this.getNumZoomLevels()));
}
I overrode the isValidZoomLevel method. The minZoomLevel and maxZoomLevel variables were set when the application started. I don't like calling javascript from GWT code, but here i didn't have any other opportunity.
Can anyone help me find out if/how you can get image data off of the 'camera roll' in an Android device, using (Appcelorator) Titanium ? I have found a 3rd party module for IOS that does this but I am desperate to find one for Android. Otherwise I'll have to scrap the Titanium and go true native.
What I need is a function that returns an array of data about the images on the device. Although I would love to get 'geolocation' data ( if it exists ), all I really need is a 'create date', and a path to the image, or the actual TiBlob.
Seems simple but i get no responses on the Appcelerator forums, which worries me. There must be at least an Android 'module' that achieves this?
Ti.Media.openPhotoGallery({
allowEditing : true,
success : function(event) {
var image = require('/modules/parts/squarecropper').crop(event.media);
setImage(image);
Ti.Media.hideCamera();
},
cancel : function() {
},
saveToPhotoGallery : false,
mediaTypes : [Ti.Media.MEDIA_TYPE_PHOTO],
});
The above method would do your job. Now then either access it directly or get into a file system and encode and decode the data.
var f = Titanium.Filesystem.getFile(currIamge);
var temp = f.read();
var encodeData = Ti.Utils.base64encode(temp);
alert("encodeData = "+encodeData);
I'm making a mobile-app using Phonegap and HTML. Now I'm using the google maps/places autocomplete feature. The problem is: if I run it in my browser on my computer everything works fine and I choose a suggestion to use out of the autocomplete list - if I deploy it on my mobile I still get suggestions but I'm not able to tap one. It seems the "suggestion-overlay" is just ignored and I can tap on the page. Is there a possibility to put focus on the list of suggestions or something that way ?
Hope someone can help me. Thanks in advance.
There is indeed a conflict with FastClick and PAC. I found that I needed to add the needsclick class to both the pac-item and all its children.
$(document).on({
'DOMNodeInserted': function() {
$('.pac-item, .pac-item span', this).addClass('needsclick');
}
}, '.pac-container');
There is currently a pull request on github, but this hasn't been merged yet.
However, you can simply use this patched version of fastclick.
The patch adds the excludeNode option which let's you exclude DOM nodes handled by fastclick via regex. This is how I used it to make google autocomplete work with fastclick:
FastClick.attach(document.body, {
excludeNode: '^pac-'
});
This reply may be too late. But might be helpful for others.
I had the same issue and after debugging for hours, I found out this issue was because of adding "FastClick" library. After removing this, it worked as usual.
So for having fastClick and google suggestions, I have added this code in geo autocomplete
jQuery.fn.addGeoComplete = function(e){
var input = this;
$(input).attr("autocomplete" , "off");
var id = input.attr("id");
$(input).on("keypress", function(e){
var input = this;
var defaultBounds = new google.maps.LatLngBounds(
new google.maps.LatLng(37.2555, -121.9245),
new google.maps.LatLng(37.2555, -121.9245));
var options = {
bounds: defaultBounds,
mapkey: "xxx"
};
//Fix for fastclick issue
var g_autocomplete = $("body > .pac-container").filter(":visible");
g_autocomplete.bind('DOMNodeInserted DOMNodeRemoved', function(event) {
$(".pac-item", this).addClass("needsclick");
});
//End of fix
autocomplete = new google.maps.places.Autocomplete(document.getElementById(id), options);
google.maps.event.addListener(autocomplete, 'place_changed', function() {
//Handle place selection
});
});
}
if you are using Framework 7, it has a custom implementation of FastClicks. Instead of the needsclick class, F7 has no-fastclick. The function below is how it is implemented in F7:
function targetNeedsFastClick(el) {
var $el = $(el);
if (el.nodeName.toLowerCase() === 'input' && el.type === 'file') return false;
if ($el.hasClass('no-fastclick') || $el.parents('.no-fastclick').length > 0) return false;
return true;
}
So as suggested in other comments, you will only have to add the .no-fastclick class to .pac-item and in all its children
I was having the same problem,
I realized what the problem was that probably the focusout event of pac-container happens before the tap event of the pac-item (only in phonegap built-in browser).
The only way I could solve this, is to add padding-bottom to the input when it is focused and change the top attribute of the pac-container, so that the pac-container resides within the borders of the input.
Therefore when user clicks on item in list the focusout event is not fired.
It's dirty, but it works
worked perfectly for me :
$(document).on({
'DOMNodeInserted': function() {
$('.pac-item, .pac-item span', this).addClass('needsclick');
}
}, '.pac-container');

I'm trying figure out how to make something like this work:
qx.Class.define("effects.Application",
{
extend : qx.application.Standalone,
members :
{
main : function()
{
// Call super class
this.base(arguments);
// Enable logging in debug variant
if (qx.core.Environment.get("qx.debug"))
{
// support native logging capabilities, e.g. Firebug for Firefox
qx.log.appender.Native;
// support additional cross-browser console. Press F7 to toggle visibility
qx.log.appender.Console;
}
var button = new qx.ui.form.Button("First Button");
var fadeToggle = new qx.fx.effect.core.Fade(button.getContainerElement().getDomElement());
fadeToggle.set({
from : 1.0,
to : 0.0
});
var doc = this.getRoot();
doc.add(button);
button.addListener("execute", function() {
fadeToggle.start();
},this);
}
}
});
This is the entire Application.js
Just trying to do an effect on something without luck.. It's like qooxdoo is ignoring the effects
The problem is the DOM element. As you execute
button.getContainerElement().getDomElement()
it has not yet appeared in the DOM tree. So the return value of the function is null. Qooxdoo has a rendering queue, so the manifestation of what you do in the program is mostly delayed a bit. Use the 'appear' event to work around this:
var button = new qx.ui.form.Button("First Button").set({
enabled: false
});
var doc = this.getRoot();
button.addListener('appear',function(){
var fadeToggle = new qx.fx.effect.core.Fade(
button.getContainerElement().getDomElement()
).set({
from : 1.0,
to : 0.0
});
button.addListener('execute',function(){
fadeToggle.start();
});
button.setEnabled(true);
});
The bit with disabling and enabling the button is just to show off ... it will be so fast that no one will notice.
There are also several *.flush() methods in the framework where you can force the rendering to happen immediately, so calling them (the right ones :-)) might also be an option ... but since JS should be written asynchronously whenever possible, the above is probably the right thing todo.
You also might want to look at
the corresponding manual page
the code of the animation demos, e.g. this (although I concede they mostly hoook the animation to user actions)
