This section talks in general about objects. Both 2-D and 3-D layouts are discussed in detail in Creating scenes.
Each object has a unique set of properties you can modify. You can specify a value for an object property and thus change its appearance. For example, you can change several Font properties for a Text object.
In general, there are three ways to modify a property:
When you map an object property, you create a direct link from the value of the property to the value of a variable, such as a parameter or a column from a query result. In most cases, when you create a layout, the Layout wizard helps you to map data points to columns returned by your query.
For more information, see Mapping object properties to column or parameter values.
QMF Visionary provides built-in functions you can use in expressions, such as the logical If() function; Max(), Min(), and other mathematical functions; geometric functions; and functions that count data points in a set or numbers of child cells in a hierarchy. For a full list of functions you can use to write property expressions, see the Function Reference in the QMF Visionary Studio online help.
Writing property expressions is described in Writing property expressions.
QMF Visionary supplies default values and, in many cases, a list box of valid values for a property. For example, a color picker is displayed when you select the Color property. To see a list of optional values for a property, in the Object Inspector, click in the entry cell adjacent to the property name.
