5.1. Creating Form Pages
With a form page you can manipulate one row at a time. You typically use a form page
when the row has many attributes and you want to show all of them.
Make the following changes to your group in the Application Definition to generate a
Form Page:
1. Set the Layout Style property to ‘form’.
There are a couple of group properties in the Form Layout category that influence this
layout style:
2. Determine the amount of horizontal space the form layout can consume on the
page as a percentage (Form Width). If you set this to 100%, the items will spread
out over the whole page. However, the items will not be aligned with each
other, but will be spread over the page to take the full space available.
If you want to force the items to be left aligned, set the value to an arbitrarily
small number. At runtime, the screen painter will see that the value is too small
and automatically increase the width just enough to display the items left
aligned. The default is 10 which will left align the items.
3. Determine the number of columns used to layout the fields in a form layout
style. The default is 2, which will leave a page with all items placed below each
other in one column.
Example of a form page:
Notice that the items are laid out in two columns as specified in the Columns property.
Attention: The display sequence of the items on the generated page is
determined by the order of the items in the group in the Application
Definition. The items are layed out from left to right, and then to the next line.
