Screens and Graphics
Besides adding, moving or deleting Objects in the Symbol, you can also edit the Object Properties as you
normally would. You may want some properties to be the same in every instance of the Symbol, but other
properties need to be customized according to where and how the Symbol is used. In this example, you
probably want to customize the captions for the three check boxes, the tags with which the check boxes
are associated, and the caption for the pane itself.
2. Select the first Object in the Symbol and open its Object Properties. For example, the first check box:
Object Properties for the First Check Box
3. In any field where you would normally configure a tag, expression, or value, you can instead define a
Custom Property using the sytax…
#[Category.]Property:[Value]
…where:
• Category is an optional name for a collection of related properties, such as all captions or all Check
Box values. If you do not specify Category for a property, then it will be automatically listed under the
"Main" category.
• Property is a label to identify the specific property. Property is required for each property, and it
must always be followed by a colon (:).
• Value is an optional default value for the property.
Note: All Tag/Expression syntax rules apply to Value, including tag names, pointers, arrays,
strings, numerical and boolean values, and scripting functions.
In the following example, we want to be able to customize which tag will be set when the Check Box is
selected or cleared. So, in the Tag field, type #Option1.Tag: as shown.
Defining a Custom Property for the Tag Field
When you go to complete the properties on an instance of the Symbol, #Option1.Tag: will appear like
this:
