question about a text object

Anonymous — Thu, 13 Aug 2015 08:43:14 GMT

Hi,

There's a text object in my model which has image as a background.

I have got 10 different images which can be used as a background. And I'd like to assign a certain image based on a certain condition.

For instance:

If Var=1, then use image1 as a background,

If Var=2, then use image2 as a background,

If Var=3, then use image3 as a background,

...

For some reason I don't want to create 10 different text objects and show/hide them based on a certain condition. I'd like to have a single text object with the possibility to assign different backgrounds.

Is it possible?

Thank you in advance,

Larisa

May be try something like this if its an external image we are talking about:

Pick(Var1, Image1, Image2, Image3, ... and so on)

I don't think the background can be manipulated like that.

If you create a text box and place it behind the first (ie in a lower layer) and make the background of the first transparent, then you can use the lower box with a Representation of Image to display the 'background' image dynamically.

Hi Jonathan,

But how can I make the lower box to display the background image dynamically?

As far as I see in the properties of a text-box there's a possibility to select only one image.

I think you can't

because when you can use an expression in Qlik there is something like (...)

and for background image I don't see a way to add an expression

Maybe you can use a chart (for background image) and a text object (for text) overlapping the 2 objects.

For managing images in a chart there is an example President.qvw, usually in

C:\Program Files\QlikView\Examples\Documents

Hope someone can find a better solution.

Hi,

Try like this.

To get images dynamically on a text object.

1. Create a variable with if condition (like if(Country='INDIA','path\Indiaflag.jpg','path\usaflag.jpg') )

2. Create a text object and give expression as =$(Vyourvariable)

and change the representation to image in general tab.

3. Create a list box and switch between values/countries, then you can see dynamic images.

Pavan.

Hi,

PFA. This might solve your problem.

Note: Please check variable and variable triggers in document properties, under trigger tab.

Thanks,

Hi Pavan,

That's a nice idea.

How can I load, say, 50 different images as a separate field on the backfront and assign certain titles for them?

I suppose, if I load them inside the model, I would not need to set a path like: 'path\Indiaflag.jpg'

Thank you in advance,

Larisa
