Everything else, such as the header and the lines are regular Scribus objects. There are also some simple text frames — those with M and F , Cost euro , Nr attending , and Totals euro are simply labels for the adjacent form elements. Below we see the form as it appears in Adobe Reader. Except for the buttons, the light blue shows the areas where some input can be entered in the form.
The word Name is a default entry that also indicates the type of input, so you would delete that and enter your name to fill out this form. In other words, all the form elements are nonfunctional in Scribus. So every time you have taken a step in the design process and you want to check if it works, you will have to take the following steps:. For our example we will make an imaginary enrollment form for a particular type of training for teachers of English as a foreign language EFL , who want to qualify in a certain methodology.
The next step will be to add the PDF form elements — seven text fields, two check boxes, one combo box and two buttons. Each has its own method:. If no programming is connected to an event, then nothing will happen when the event occurs. If a program is connected to an event, then it will be executed every time the event takes place! In our form we will add a button that will print the form when the user clicks the button.
We will use the mouse down event the mouse button is clicked when the mouse pointer is positioned over the button to program the fragment that will execute this task. This programming method is called event-driven programming. Buttons can be enhanced with a little image on them. We call this an icon.
Alternatively you might just add a short text to the button face. Adding text to a button in Scribus is comparable to adding text to a text field. An icon for a button is also quite doable. The next task that awaits us is to set up all fields through the dialog box Field Properties. In practice generic names are cumbersome, because they are also used to present the results of a form when it is send by e-mail.
Programmers often use a different type of naming, the so called Hungarian Notation. The type of object is mentioned in the name we call a field an object or control. In this case English is the predominant language and names would look like this:. You know now that you can set up the fields by double clicking them in order to make choices in the dialog box Field properties. The next table gives you all necessary information:.
When defining the field NrAt you will see that we use a validation. This means that as long as the number 0 zero , the form is considered to be not completed correctly. Thus we force the user to fill in a number equals to or larger than 1. By doing so the price of the training selected in the combo box will be processed in the text field Cost. Check out the other possible links in the Annotation field.
This completes the setup of the fields. As I have explained before we use JavaScript to automate certain events. There is no need for you to have any specific programming experience to be able to understand the code snippets that we use here.
How to interpret this? The snippet is located in the Mouse up event of the check box M. So if some clicks here as a result a tick mark will be placed in the box. This means however that the standard tick mark in checkbox F must be removed.
DrawRectangle method:. It is very important to note that not all the PDF viewer apps support these actions. The way to configure a RadioButton instance as a member of a group is by using the same name.
For example, the following code:. These controls behave similar to what you expect in any Xojo project. You can populate them with a series of default options and set one of them as the selected option displayed by default. The main difference is that a PDFComboBox lets the user type text that is not available among the assigned options. So the getField function is a member of the Document Object.
The this , is a keyword in scripting that refers to the current object. In nearly all scenarios where this code is used the this keyword will be a reference to the Document Object where the field exists.
There are times when a different Document Object prefix is used but they are rare, mostly in automation scripts. The other important bit in this code is the function input, which is the field name.
In this code "FieldName" is a placeholder. In your code "FieldName" will need to be replaced with the name of the field on your form that needs to be acquired.
Names are important for data handling because the field name is used as the data name when data is exported from a form. That data may need to be integrated into a data system, or loaded into a different form. Whatever the use, good names make the data easier to identify and map. Events are a core component of form scripting. These video tutorials explain the details how event scripts are entered and used. The Acrobat user interface has changed since these videos were developed.
This UI change only affects the tool buttons and menu items at the top level. All the dialogs and concepts shown are the same. This is where anything that needs to be setup for the form is done, such as defining functions and variables used by other scripts. For example, it's quite common to define data used on the form, or create a calculation function that will work for several different fields, such as line totals on an order form.
Document Scripts Calculations Operations such as totaling cost, calculating percentages, and other types of mathematical calculations are necessary for many kinds of forms, but form calculation scripts can do much more than this.
There is a wide variety of types and uses of calculations in PDF scripting. Data can be moved out of the form and into a different format spreadsheet, database or into some other data system.
The reverse is also true, sometimes data needs to be loaded into a PDF form from some other data source. Acrobat and the scripting model provides several different options for importing and exporting data.
Form Data Handling Field Manipulation It can be quite useful to manipulate the properties of fields on a form in order to enhance user interaction. Acrobat provides a set of built-in data formats. A custom format script is used if the desired format is not available on this list, or if the format script is needed for other purposes.
Format scripts are useful for a variety of tasks because they are triggered right after new data is entered into a field. Of course, formatting is most strongly associated with text fields, since they are the only field type that can actually use display formatting. However, it's possible to use a format script on any field. There are many variation on this process that depend on how the form is to be used.
And the events used for validation have many alternate uses. Validation Scripts Common Elements in Scripting There are many devices and concepts that are not specific to a particular type of scripting, such as dates, colors, file paths, page coordinates, and many more.
It is often desirable for an unfilled form or form section to be empty. Unfortunately, if there are calculations, an unfilled form can have several fields full of zeros. This article will teach you 4 different ways to blank out zero values One of the most common PDF error messages encountered by new form designers, is "The value entered does not match the format of the field.
