I'm using a HtmlView for some html text I get through a json feed. However, I want to center it under an image and am having trouble figuring out how to style the elements inside the view. I know how to set the width of the element itself, but how do I style the content?
Use text-align with style attribute,
<HtmlView html="<div style='text-align: center'>this text should be in center of view</div>"></HtmlView>
Note: I was told that text-align: center may not work in Android < v7.0. In which case you will have to set the gravity on native view.
// Do this in loaded event of TextView
const nativeView = args.object.android;
if (nativeView) {
nativeView.setGravity(android.view.Gravity.CENTER_HORIZONTAL);
}
Here is a Playground sample.

My jqplot graphs have, sometimes, long texts as tick text.
I'd like to ask if is any way to short that text (using jqplot) and to add a tool tip with full text on the tick label?
I hope this will help someone looking for the same solution, Originally answered by me here.
The hover is not detecting because of the z-index of the canvas which lies on top of the whole chart. I did the following and now it's shorten the tootip by CSS ellipsis and show the tooltip with full name on hover.
Based on the Gyandeep's answer, the exact JS and CSS I used are,
Javascript:
$('div.jqplot-xaxis-tick').each(function (i, obj) {
$(this).prop('title', ($(this).text()));
$(this).css('z-index', 999); // this is important otherwise mouseover won't trigger.
});
CSS:
.jqplot-xaxis .jqplot-xaxis-tick {
position: absolute;
white-space: pre;
max-width: 92px; // Change it according to your need
overflow: hidden;
text-overflow: ellipsis;
}
The JavaScript part needs to be executed after every rendering of chart. It's better to put them right after plotting the chart and may in the AJAX success handler.
Can any one tell me how to place my html content on a canvas.And if we can do that, will the properties and events of those elements works or not, and also I have animations drawn on that canvas.
From this article on MDN:
You can't just draw HTML into a canvas. Instead, you need to use an
SVG image containing the content you want to render. To draw HTML
content, you'd use a element containing the HTML, then
draw that SVG image into your canvas.
It than suggest you follow these steps:
The only really tricky thing here—and that's probably an
overstatement—is creating the SVG for your image. All you need to do
is create a string containing the XML for the SVG and construct a Blob
with the following parts.
The MIME media type of the blob should be "image/svg+xml".
The element.
Inside that, the element.
The (well-formed) HTML itself, nested inside the .
By using a object URL as described above, we can inline our HTML
instead of having to load it from an external source. You can, of
course, use an external source if you prefer, as long as the origin is
the same as the originating document.
The following example is provided (you can see more information about this in this blog by Robert O'Callahan):
DEMO
const ctx = document.getElementById("canvas").getContext("2d");
const data = `
<svg xmlns='http://www.w3.org/2000/svg' width='200' height='200'>
<foreignObject width='100%' height='100%'>
<div xmlns='http://www.w3.org/1999/xhtml' style='font-size:40px'>
<em>I</em> like <span style='color:white; text-shadow:0 0 2px blue;'>CANVAS</span>
</div>
</foreignObject>
</svg>
`;
const img = new Image();
const svg = new Blob([data], {type: "image/svg+xml;charset=utf-8"});
const url = URL.createObjectURL(svg);
img.onload = function() {
ctx.drawImage(img, 0, 0);
URL.revokeObjectURL(url);
};
img.src = url;
<canvas id="canvas" style="border:2px solid black;" width="200" height="200"></canvas>
This example results in this HTML being rendered to canvas as this:
Will the properties and events of those elements works or not ?
No, everything drawn to a canvas is forgotten as passive pixels - they becomes simply an image.
You will need to provide custom logic that you provide yourselves in order to to handle any such things as clicks, objects, events etc. The logic need to define the areas, objects and anything else.
I'm using a sprite image to change the background on hover and click (the .keepImage class is for the click). It all works, but when the background picture changes it scrolls over to the correct position. Is there a way to do it without the scrolling motion?
JS:
<script>
$(document).ready(function(){
$("a.doing").click(function() {
$(this).siblings(".keepImage").removeClass("keepImage");
$(this).addClass("keepImage");
});
});
</script>
CSS:
a.doing {
width: 229px;
height: 202px;
margin-right: 8px;
background: url(http://localhost:8000/img/manifesto/spr_doing.png) 0 0;
}
a.doing:hover, a.doing.keepImage {
background: url(http://localhost:8000/img/manifesto/spr_doing.png) -229px 0;
}
I think, somewhere in your css you have the transition property specified. Usually when you have a transition property specified like this: "transition: all 500ms ease;", the background position will change with a scrolling effect. If you want to prevent this scrolling from happening, then you can either remove the transition property completely, or you can use transition only for the properties you want to animate like - border, color etc.. but not background. If you can somehow provide a link to your page, or give the html mark up and css, it will help. Thanks.
I have been trying to put an image with a hyperlink on it into a google apps script ui. I first thought of using createAnchor(), but that only allows text. Then I thought of using a button, but as far as I know you cannot open a new tab/window and redirect in a callback function.
I also tried createHTML(), but the element is not handled by it as yet.
I have seen people overlay transparent buttons over images, but still have same issue in callback.
My research has not found an answer to this. Does anyone have any solutions/examples?
Thanks
This worked for me on Chrome20 and IE9
// Container for box and results
var imageContainer = app.createFlexTable();
// Setup the button
var button = app.createButton("ImageButton");
button.setStyleAttribute("background", "url(dontshowimagehere.JPG) no-repeat");
button.setStyleAttribute("position", "absolute");
button.setStyleAttribute("color", "transparent");
button.setStyleAttribute('zIndex','1');
button.setStyleAttribute("border", "0px solid black");
imageContainer.setWidget(0, 0, button);
// image to click
var image = app.createImage("image.jpg").setId(imageId);
imageContainer.setWidget(1,0, image);
The image has a slight (3px) offset. If important, this looks to fix it http://www.w3schools.com/css/css_positioning.asp (use relative for the flex table and top etc for the image and button)
Did you try a transparent Anchor overlaying the image?
function doGet() {
var app = UiApp.createApplication().setTitle("Image Anchor");
var panel = app.createAbsolutePanel().setWidth('50%').setHeight('50%');
var image = app.createImage().setUrl("https://lh6.googleusercontent.com/-v0Q3gPQz03Q/T_y5gcVw7LI/AAAAAAAAAF8/ol9uup7Xm2g/s512/GooglePlus-512-Red.png").setStyleAttribute("width", "28px").setStyleAttribute("height", "28px");
var anchor = app.createAnchor("?", "https://plus.google.com/u/1/116085534841818923812/posts").setHeight("28px").setWidth("28px").setStyleAttribute("opacity", "0.1").setTarget("blank");
panel.add(image,100,50);
panel.add(anchor,100,50);
app.add(panel);
return app.close();
}
app.createAbsolutePanel()
.add(app.createImage('https://www.google.com/images/logos/google_logo_41.png'))
.add(app.createAnchor('','https://www.google.co.uk/intl/en/about/')
.setStyleAttributes({position:'absolute',top:'0px',left:'0px',width:'201px',height:'47px',opacity:'0'}))
This is a tested one. It works fine.
It doesn't work with positioning the image (as 'absolute').
It doesn't work with .setHorizontalAlignment(UiApp.HorizontalAlignment.CENTER)
I don't believe this is possible with the widgets available. I would suggest altering your UI's design to utilize an Anchor widget instead.
Use HTML Box if you are coding directly on your page. Click "Edit" to edit your page and go to "Insert>HTML Box" in your menu. It will accept javascript too! There are a few caveats - when using javascript, HTML Box will not accept links...too bad, but too many exploits there.
If you are coding in apps script, you could try to place the image on a panel and use absolute panel and position your link over your image. Another method could be to use the .setStyleAttribute for CSS styling and utilize the zIndex parameter to place a panel over top of your image....like so:
var panel = app.createSimplePanel();
// add your image to the simple panel or whatever panel you wish to choose in your GUI
var popPanel = app.createSimplePanel()
.setStyleAttribute('top','Y')
.setStyleAttribute('left','X')
.setStyleAttribute('zIndex','1')
.setStyleAttribute('position','fixed');
// add your anchor to the popPanel
app.add(panel).add(popPanel);
Not 100% sure if you can make this panel transparent, but you could try something like:
.setStyleAttribute('background',transparent')
or change the opacity via:
.setStyleAttribute('opacity','.5')
Hopes this gives you a few ideas!
I managed to do it with a single Anchor object and using CSS3.
It works on Chrome, I did not test it in other Browsers.
gui.createAnchor("", false, "$DESTINATION_URL$")
.setStyleAttributes({ "display":"block",
"width":"$IMAGE_WIDTH_IN_PIXEL$",
"height":"$IMAGE_HEIGHT_IN_PIXEL$",
"background":"url($URL_OF_THE_IMAGE$)",
"background-size":"100% 100%",
"background-repeat":"no-repeat" })
Of course you have to replace the $......$ with your data.

If you first create all your HTML in a string, you can then replace the content of a page with the HTML you want like this:
var myString = 'the html you want to add, for example you image link and button';
var page = SitesApp.getSite('example.com', 'mysite').getChildByName('targetpage');
var upage = page.setHtmlContent('<div>' + myString + '</div>');
I have a main view, then on that view I have, as children, two labels and an image. I want the labels to flow one after another from the top of the screen and I want the image at the bottom. I get the labels to flow properly by setting layout:'vertical' in the main window. But once that is done, I can't seem to force the image to the bottom. Here is a snippet of my code:
var self = Ti.UI.createView({
backgroundColor:'#fff',
layout:'vertical'
});
var l1 = Titanium.UI.createLabel({
text:quote,
color:'#000',
shadowColor:'#ddd',
shadowOffset:{x:2,y:2},
font:{fontFamily:'Marker Felt',fontSize:24},
top:20,
left:15,
right:15,
height:'auto'
});
self.add(l1);
var l2 = Titanium.UI.createLabel({
text:author,
color:'#000',
shadowColor:'#ddd',
shadowOffset:{x:2,y:2},
font:{fontSize:16},
top:10,
left:15,
right:15,
height:'auto',
textAlign:'right'
});
self.add(l2);
var imgView = Titanium.UI.createImageView({
image:myimage,
setBottom:10,
height:100
});
self.add(imgView);
I have tried setting the image layout and that doesn't work. If I change the 'self' window layout to 'absolute' then I can't seem to get the labels to flow cleanly after one another. The first label is of variable height so I need them to follow each other.
I am using Titanium 1.82.
Thanks. In advance.
You might need to add another view. The 'base' view would have what you are calling 'self' added at top:0 and height: 'auto'
Then add imgView to 'base' with bottom: 10 (not setBottom like you have).
Just set the bottom:0; position: fixed; i think this will help u to set the image bottom of the screen.. If it still not working means try with Html,Css and Javascript for design it will be very easy.
