Get width of a label in Titanium mobile app

How can I get the width of a label after set its contents? No initial width set to it.

I have two labels within a table row like followings:

label 1 (label 2)

Here the width of label 1 is not set initially. with the change of contents label 1's width has changes and sometimes it causes overlapping with label 2.

Now my main aim is to set the label 2 left dynamically that it does not ovelapp with label 1. I want to do it like following:

1. first calculate the width of label 1
2. then set the left of label 2 = width of label 1 + 10

if there is any other way please help.

HERE SOME CODE

var win = Titanium.UI.createWindow({
    title: 'Cleos',
    backgroundImage: 'tablebg.png',
    navBarHidden: true,
});
var tableview = Titanium.UI.createTableView({
    backgroundColor: 'transparent',
    separatorStyle: Ti.UI.iPhone.TableViewSeparatorStyle.NONE,
    style: Titanium.UI.iPhone.TableViewStyle.PLAIN
});
win.add(tableview);
var modelData = new Array;
for (i = 0; i <= daga.length - 1; i++) { // `data` as json, comes from a source
    var row = Titanium.UI.createTableViewRow({
        height: 120.0,
        backgroundColor: 'transparent',
        selectedBackgroundColor: '#380710',
        hasDetail: true
    });
    var imageThumb = Tit开发者_运维知识库anium.UI.createImageView({
        image: '...',
        width: 100.0,
        height: 100.0,
        left: 4.0,
        top: 10.0
    });
    row.add(imageThumb);
    var name = Titanium.UI.createLabel({
        text: '...',
        font: {
            fontSize: 16,
            fontWeight: 'bold'
        },
        textAlign: 'left',
        color: '#fff',
        height: 30.0,
        top: 5.0,
        left: 110.0
    });
    row.add(modelname);
    var NumberOfImages = Titanium.UI.createLabel({
        text: '(' + 12 + ')',
        font: {
            fontSize: 16
        },
        width: 'auto',
        color: '#bfbebe',
        textAlign: 'left',
        height: 30.0,
        top: 5.0,
        left: '' // I want to set this `left  = width of label name`
    });
    row.add(NumberOfImages);
    modelData.push(row);
    tableview.setData(modelData);
}
win.open();

var width = label.toImage().width;

This will get the real width or height (in pixels) of the image AND it takes into account the font properties (size, family, weight).

---

var labelWidth = label.width;

but be careful with 'auto' values since they often return 0. the value should be requested after adding the label to the view.

[update] if NumberOfImages.left = name.width+name.left; doesn't work i would try to calculate the width like

var pixelPerChar = 8;
var pseudoWidth = name.text.length/pixelPerChar;
NumberOfImages.left = pseudoWidth + name.left;

---

Set both width AND height to auto, then it should return a proper value.

---

Titanium labels with auto sizes tend to be annoying (or were when I last worked with Titanium); a solution that often works is to place them inside of a TiView with auto width or height and then read the relevant property from the view.

Set the width of name to 'auto' when you create it.

After you add name to row, you can get the width by name.size.width

---

Setting width to 'auto' seems to clip to 320 (the label won't stay one line if its bigger than the screen width). Is there a way to have a label bigger than the screen with an automatic width go past the screen edg

I have also this type of problem in Starting. You, solve this problem easily, u set the height with %age (percentage). It means, when u define label.height = 10% label.left = 5% etc then, it calculate the screen current height and set by default with percentage.

In This use we have also a profit. when we change the orientation than it take place easily, with percentage.

Thanks
