Separate themes for separate objects
As you can see in the
Insertion of properties in theme
dialog
window, the settings for all charts are stored in a single
Chart
type. This can create difficulties when you want to apply
different settings to different charts. For example, showing a grid
for line charts, but hiding it for bar charts. In that case, it is easier
to create separate theme files for each of your chart objects.
A solo exercise
By now, you have probably spotted the pattern of creating and adding settings
to a theme file, so it is time for a little solo exercise. We still need to add the list
box properties based on the
Flight Type
list box to our theme. Make sure to pay
special attention to the
Show Caption
setting as we want to ensure that a caption is
displayed on our list boxes. Besides the list box, make sure to apply the
Caption &
Border
settings to the following objects as well:
• Statistics Box
• Multi Box
• Table Box
• Input box
• Current Selections Box
• Bookmark Object
If you are able to successfully complete this exercise, then you have all of the skills
necessary to create and modify your own themes.
You can test your new theme file by applying it to the
NoTheme.qvw
file that we used
earlier in this chapter.
Additional interactivity
Besides properly styling your QlikView documents, how your document responds
to user interaction is also critical to ensuring a pleasant user experience. Fortunately,
most of the interaction is already built into the list boxes, charts, and so on, but there
are a few options that can help you make your document even more polished.
We will first look how we can make QlikView respond to certain events by using
triggers and actions. We'll then see how we can create an advanced search expression
that lets us search for data in a flexible manner. We will see how we can use these
advanced search expressions to send out alerts when predefined conditions are
met. We will end this section by looking at how to conditionally calculate or show
an object.
