Example 4: changing the size and location of controls

To modify properties conditionally at runtime:

1. Position the pointer on the control, band, or DataWindow
   object background whose properties you want to modify at
   runtime.

2. Select Properties from the pop-up menu, then select the page
   that contains the property you want to modify at runtime.

3. Click the button next to the property you want to
   change.

4. Scroll the list of functions in the Functions box until you
   see the IF function, and then select it:

   

5. Replace the b (boolean) with your condition (for example,
   salary>40000).

   You can select columns and functions and use the buttons to
   add the symbols shown on them.

6. Replace the t (true) with the value to use for the property if
   the condition is true.

   Values to use for properties are usually numbers. They are
   different for each property. For more information about property
   values that can be set on the Expressions page, see Supplying property values.

   Set Font.Weight property to 700 for bold

   Font properties such as Italic, Strikethrough, and Underline
   take a boolean value, but to specify a value for bold, you use the
   Font.Weight property, which takes a range of values. For values
   and an example, see Font.Weight.

   For complete information about what the valid values are for
   all properties of controls in the DataWindow object, see the
   discussion of DataWindow object properties in DataWindow Object Properties in DataWindow Reference.

7. Replace the f (false) with the value to use for the property
   if the condition is false.

8. Click OK.

   For examples, see Example 1: creating
   a gray bar effect, Example 2:
   rotating controls, Example 3:
   highlighting rows of data, and Example 4: changing the size and location of
   controls.
