Chapter 15: Creating a Custom iTool Widget Interface 349

iTool Developer’s Guide Adding an iTool Window

• by interactively importing new data and creating new visualizations using the

iTool Data Import Wizard or Insert Visualization dialog.

These methods are standard to all iTools, and are discussed in the iTool User’s Guide.

The contents of the iTool window can also be manipulated programmatically from

“outside” the iTool framework in various ways:

• by applying an operation using the iTool object’s DoAction method.

• by changing a property value using the iTool object’s DoSetProperty method.

• by importing and visualizing new data, either by calling an iTool creation

routine with the VIEW_NUMBER keyword set to replace the existing

visualization, or by retrieving the iTool data item and using its SetData

method.

These programmatic methods for modifying the contents of an existing iTool are

discussed in Appendix A, “Controlling iTools from the IDL Command Line”.

Resizing iTool Windows

The CW_ITWINDOW compound widget defines a separate procedure,

CW_ITWINDOW_RESIZE, that accepts as arguments the new width and height of

the iTool window. This procedure handles all calculations necessary to properly

resize the window, taking into account the current zoom factors and the presence or

absence of scroll bars. See “CW_ITWINDOW” on page 416 for complete details.
