examples how to use SetStyle action

Hello David,

may be this is a bit boring for you and beside your main work ... but do you think it ist possible to create a small sample which shows some main examples how to use SetStyle? I try hard to work it out i.e. changing the position and size of a object with CCS in runtime (!) , also border attributes etc. I was susccesfull to move a textarea with marginTOP etc. but I´m to stupid to change the size of the textarea ...
many thanks for your work and help!

By the way: please check the If action, I think there are some bugs in the dropdown list of the second operators ...

Hello Walter,

Take a look at the bellow code, which change the top, left, width and height of a Textarea control.

As you can see we need to specify a measure, in this case "pixels". If you plain to establish lot of CSS properties maybe another possible approach is to use a Cascading Style Sheet file, a CSS file which you can include in the app files/styles, and which are included and linked by App Builder automatically. The SetStyle action expect a CSS property name, just like if you defined it in a CSS file, and the appropiate value, including a measure when needed.

Just take in count that every app control have an ID, which is the same that their name. Then, for example, to establish a CSS properties for a "Textarea1" control, we must use the ID "#Textarea1" in our CSS file. Maybe you can take a look at the Responsive apps tutorial included in the program help. Such tutorial indicates various ways to use CSS styles, and how we can get beneficts defining CSS "media queries" in our CSS styles.

About the "If" action's editor error, can you explain a little more? Just yesterday I fix an error which cause that the operator description are added to the action argument, but I don't know if you refer to this problem or another one.

Hello David,
thanks a lot. This was exaktly, what I did, but there must have been an error in my code ... I set up a new test.app and now it works. Thanks!
Concerning IF-operator: Seems the dropdown-list and the result in the field are not the same. Example: select "=! (not equal) in the dropdown list results a ">" in the field second operator. I tested them, they all are different exept the first ...
My OS is 8.1

I´m getting more and more happy with Appbuilder! When to register? Now? Want to support your work !

Hello again,

I can imagine that maybe you try to use the CSS properties as is shown into the control's object inspector. That is, for example, maybe you are trying to use the "SetStyle" action like:

The above action doesn't produce the expected results. In fact the designtime CSS properties have such kind of names because, for example, they cannot contains the "-" character.

In runtime, we need to specify a real and valid CSS property name like:

A good CSS properties reference can be found here at W3 Schools.
