TAGCLOUD

The TAGCLOUD control represents a collection of tags. A tag is a keyword assigned to an information resource (picture, video clip or others). In a tag cloud, the tags are mainly shown by their popularity.

The following topics are covered below:


Example

Tagcloud

As you can see, different tags can be added to a tag cloud. They differ by their popularity. The most popular tags are those with a bigger font size.

The XML layout definition is:

<itr>
   <tagcloud tagcloudprop="tagCloud"
          width="300" height="350"
          borderstyle="dotted" borderwidth="1px"
          bordercolor="#0000FF" backgroundcolor="#E6E6FA"
          textcolor="#0000FF">
   </tagcloud>
</itr>

The tag cloud can be customized by defining a background color.

Name of the adapter parameter that represents the control in the adapter.

Obligatory  
width

Width of the control.

There are three possibilities to define the width:

(A) You do not define a width at all. In this case the width of the control will either be a default width or - in case of container controls - it will follow the width that is occupied by its content.

(B) Pixel sizing: just input a number value (e.g. "100").

(C) Percentage sizing: input a percantage value (e.g. "50%"). Pay attention: percentage sizing will only bring up correct results if the parent element of the control properly defines a width this control can reference. If you specify this control to have a width of 50% then the parent element (e.g. an ITR-row) may itself define a width of "100%". If the parent element does not specify a width then the rendering result may not represent what you expect.

height

Height of the control.

There are three possibilities to define the height:

(A) You do not define a height at all. As consequence the control will be rendered with its default height. If the control is a container control (containing) other controls then the height of the control will follow the height of its content.

(B) Pixel sizing: just input a number value (e.g. "20").

(C) Percentage sizing: input a percantage value (e.g. "50%"). Pay attention: percentage sizing will only bring up correct results if the parent element of the control properly defines a height this control can reference. If you specify this control to have a height of 50% then the parent element (e.g. an ITR-row) may itself define a height of "100%". If the parent element does not specify a width then the rendering result may not represent what you expect.
