Quick one for any developers using appcelerator out there. I have two labels (This may even bew wrong) which are populated from an RSS feed. One label houses the title and another the description. The content for these comes from an RSS list which all works fine. THe issue I'm having is that some titles are longer than others so I cant fix label heights or it just wont work.
So with that in mind I set the titles height to be auto. The only problem is I cant reference this height from my second label to use the top: property to space it correctly.
Has anyone got any good suggestions?, Am I using the wrong type of Titanium UI method?
My current code is as follows
try
{
var current = Titanium.UI.currentWindow;
var selectedItem = current.item;
var description = selectedItem.getElementsByTagName("description");
var story = description.item(0).text;
var label = Ti.UI.createLabel({
text:selectedItem.getElementsByTagName("title").item(0).text,
left:5,
top:0,
height:"auto",
font:{fontSize:40}
});
current.add(label);
var story = Ti.UI.createLabel({
text:story,
left:5,
top:label.height,
height:"auto"
});
label.add(story);
}
catch(E)
{
alert(E)
}
minimumFontSize
the minimum size of the font when the font is sized based on the contents. Enables font scaling to fit and forces the label content to be limited to a single line
On the containing window / view, set the layout property to 'vertical' - this means the views are stacked on top of one another so your top value doesn't have to know the height of the previous component.
// Windows
var window = Ti.UI.createWindow({
layout: 'vertical',
backgroundColor: '#FFF'
});
var label = Ti.UI.createLabel({
width: 200,
height: 'auto',
text: 'some long text'
});
var label2 = Ti.UI.createLabel({
width: 200,
height: 'auto',
text: 'more long text',
top: 10 // This just adds some padding between the two labels
});
window.add(label);
window.add(label2);
window.open();

I am using sap.m.Table to display some documents as a sap.m.Dialog.The UI looks as below:
Everything works as expected but when I scroll to the last Item (growing=true) the table rerenders and moves back to the top. Ideally that would happen only when I refresh a model. I am using bindAggregation to bind the odataModel to the UI. Please see a snippet below (Note:Partial snippet).
var dialog = new Dialog({
title: title,
buttons: [
new sap.m.Button({
text: "{i18n>close}",
press: function(oEvt) {
dialog.close();
}
})
]
});
var table = new sap.m.Table({
width: "100%",
inset: true,
growing: true,
growingThreshold: 100,
growingScrollToLoad: true
})
dialog.addContent(table);
if (!dialog.isOpen()) {
dialog.open();
}
var oDModel = new ODataModel(kmURL, {
json: true
});
oDModel.setDefaultBindingMode(sap.ui.model.BindingMode.OneWay);
table.setModel(oDModel);
var mParams = {
path: "/DocumentQuerySet",
template: template,
};
table.bindAggregation("items", mParams);
I think that bindAggregation internally refreshes the model which forces the table to rerender after every data call. How can I avoid the model to refresh/rerender the table so that it does not scroll to the top every time the user scrolls down to see more data.
Appreciate any help.
Thanks.
You could fix this problem by placing the Table control within a ScrollContainer. The ScrollContainer will handle the growing feature of the table, which causes the change in height of the control. This will retain the current position without moving back to the top.
....
var table = new sap.m.Table({
width: "100%",
inset: true,
growing: true,
growingThreshold: 100,
growingScrollToLoad: true
})
var oScroll = new sap.m.ScrollContainer({
width: "100%",
height: "500px",
vertical: true,
content: table
})
dialog.addContent(oScroll);
....
I'm having trouble setting the number of rows for a table to automagically fill the available estate of its encapsulating container.
According to the API, setting the visibleRowCountMode property to sap.ui.table.VisibleRowCountMode.Auto should render the table to
"[...] automatically fills the height of the surrounding container.
The visibleRowCount property is automatically changed accordingly. All
rows need the same height, otherwise the auto mode doesn't always work
as expected."
I have used the following code:
var oTable = new sap.ui.table.Table( {
rowHeight : 30,
height : "100%",
// The below property is seemingly ignored... What did I do wrong?
visibleRowCountMode : sap.ui.table.VisibleRowCountMode.Auto
});
...but as you can see in this jsbin example http://jsbin.com/vazuz/1/edit it just shows the default 10 rows, and certainly doesn't "change the visibleRowCount property accordingly" :-(
Anyone has a solution?
Thanks in advance!
=====================
EDIT: Thanks to #matz3's answer below, I was ultimately able to solve this issue.
Setting the surrounding container DIV to 100%, this seems to be ignored. Setting it to a fixed height, however, worked just fine. But what I really wanted, if a user resized the window, the number of available rows needs to be adjusted accordingly. Setting it to a fixed height is therefor not an option...
However, the trick was in some extra CSS: not only the DIV needed to be set to 100% height, also both BODY and HTML (!!) needed to have a height set to 100%:
html, body {
height: 100%
}
div#uiArea {
height: 100%
}
Now, the table spans the full height of the available viewport, and resizing the window adjusts the table rather nicely. See the final working solution here: http://jsbin.com/bosusuya/3/edit
Matz3, thanks for your help!
CSS hacks is a dirty way. In my application I use to bind visibleRowCount to Array.length
For example, if you have model with this data:
[{firstName: 'John', lastName: 'Smith',
{firstName: 'David', lastName: 'Ericsson'}]
You can bind to Array property length like this:
var oTable = new sap.ui.table.Table({
visibleRowCount : '{/length}'
})
[...] automatically fills the height of the surrounding container [...]
Your surrounding container is the view, so you have to set the height of it also to a value (e.g. 100%)
this.setHeight("100%");
And your view will be set into the uiArea-div, so this one also needs a height (e.g. 500px)
<div id="uiArea" style="height:500px"></div>
With these changes it now works as expected
I'm with the same issue. I "resolve" that in this manner. This is not perfect, but it's better than UI5 resizing...
_resizeTableRow: function () {
var oTable = this.getView().byId("referenceTabId");
var sTop = $('#' + oTable.getId()).offset().top;
var sHeight = $(document).height();
//if there a row, you can take the row Height
//var iRowHeight = $(oTable.getAggregation("rows")[0].getDomRef()).height();
var iRowHeight = 40;
var iRows = Math.trunc((sHeight - sTop ) / iRowHeight);
oTable.setVisibleRowCount(iRows);
},
Other option is to put the Table in sap.ui.layout.Splitter:
I'm manually porting an extension I wrote in Chrome over to Firefox. I'm attaching a panel to a widget, and setting the content of that panel as an HTML file. How can I make the panel shrink and grow with the content? There's a lot of unsightly scroll bars and grey background right now.
var data = require("self").data;
var text_entry = require("panel").Panel({
width: 320,
height: 181,
contentURL: data.url("text-entry.html"),
contentScriptFile: data.url("get-text.js")
});
require("widget").Widget({
label: "Text entry",
id: "text-entry",
contentURL: "http://www.mozilla.org/favicon.ico",
panel: text_entry
});
Not setting the height property of the panel makes it quite tall.
You might want to check out this example that resizes the panel based on the document loaded. If you want to resize based on changes to the content size, at least on initial load:

I am new to Titanium Studio. Need to set row height dynamically but, I unable to set dynamic height in each row. Below is my code:
textArray contains 10 text paragraphs. each paragraph have different height.
var myTable = Ti.UI.createTableView({height:360, width: 306, top: 58, backgroundColor: '#FFFFFF',borderColor: '#C8C8C8',borderWidth:2, zIndex: -1});
var myArray = [];
for(int i = 0; i < 10; i++)
{
var row = Ti.UI.createTableViewRow({contentHeight: 'auto', width: 320,top:0});
var my = Ti.UI.createView({ top:10,width:300,height:'auto' });
var myText = Ti.UI.createlLabel({text:textArray[i],width:50,height:'auto',left:10,top:5,borderRadius:4});
my.add(myText);
row.add(my);
myArray.push(row);
}
How can i set row height dynamically.
Can any one help?
As per understanding you need to show cell height as per text
Here are some good example

Example given on some blog
Hope this will solve you problem.
I got the solution:
specify your table rowHeight as auto.
var myTable = Ti.UI.createTableView({height:400,rowHeight: 'auto', width: 312, top: 10,left:4, backgroundColor: '#FFFFFF',borderColor: '#C8C8C8',borderWidth:2, zIndex: -1});
var myArray=[];
for(int i = 0; i < 10; i++)
{
//create row in table.
var row = Ti.UI.createTableViewRow({height: 'auto', width: 310,top:10, selectionStyle : Titanium.UI.iPhone.TableViewCellSelectionStyle.NONE});
//textArray contains 10 elements. i am using this in each loop..
var myText = Ti.UI.createlLabel({text:textArray[i],width:50,height:50,left:10,top:5,borderRadius:4});
//add like this what ever you want...
row.add(myText);
myArray.push(row);
}
//store in table
myTable.data = myArray;
//disply table.
win.add(myTable);
If height:'auto' property is not working then use Ti.UI.SIZE
I hope.. someone will use it.
Change the content height to what you want table height look
In my code I am doing this:
var taskLabel = Ti.UI.createLabel({color:'#777', top:3, textAlign:'center', height:'auto', text:task.title});
Ti.API.info('Next info is: taskLabel.height');
Ti.API.info(taskLabel.height);
But, the output from this is:
[INFO] [123,883] Next info is: taskLabel.height
And nothing more, it looks like it breaks silently, but I guess it shouldn't, based on the API.
I am trying to sum some heights of the elements, but I would prefer it behaved like html postion:relative. Anyway, I'd like to read the height in float, how can I achieve that?
You need to set a fixed width when you use an auto height. For example:
var taskLabel = Ti.UI.createLabel({color:'#777', top:3, textAlign:'center', height:'auto', width: 200, text:task.title});
you are not going to get the height until it is actually rendered and added to view or window.
You cant read the height property off like that, if you didn't manually define it.
It has to be added to a view, and then displayed (assuming it doesn't auto display) before Titanium will return anything about the height.
var window = Ti.UI.createWindow();
var taskLabel = Ti.UI.createLabel({color:'#777', top:3, textAlign:'center', height:'auto', text:task.title});
window.add(taskLabel);
window.open();
Ti.API.info('Next info is: taskLabel.height');
Ti.API.info(taskLabel.height);
That should work to show the height.
This should work.
var lbl_obj = Ti.UI.createLabel( { height: 'auto', text:'Test Label', top:10 } );
var height = lbl_obj.toImage().height;
Ti.API.info(height);
