Editing DataItem parts with the source assistant

Like most parts, DataItem parts can have one or more properties assigned to them. The source assistant helps you assign the correct properties and values for the DataItem by displaying only the valid properties for DataItem parts and by validating the values that you enter for the properties.

To modify DataItem properties, follow these steps:
  1. Open an EGL source file.
  2. Select the DataItem that you want to edit. The cursor must be on the DataItem.
  3. Open the source assistant by using one of these methods:
    • Press Ctrl + Shift + Z.
    • Right-click the DataItem and then click Source Assistant.
  4. In the EGL Source Assistant window, type the name of the DataItem in the Name field and select the type from the Type field.
  5. If the type of DataItem requires a length or a number of decimal places, specify these values in the Length and Decimals fields. These fields are not available if the DataItem does not require a length or number of decimal place values.
  6. Specify values for the properties of the DataItem. You can switch between different pages of properties by clicking the tabs below the Type field.
  7. When you are finished editing the values, click Validate.

    The source assistant validates the values you enter and lists any errors at the bottom of the window. Correct any errors that are listed in the window and click Validate again.

  8. When there are no more validation errors listed, click OK. The source assistant closes and updates the DataItem properties to match the properties that you specified.
  9. Save the EGL source file.
