Making Multiple GUIs Work Together

(pt(1,2)>=0 && pt(1,2)<=cols);

Closing All Windows When Complete

When the Icon Editor opens, it opens the C olor Palette and Tool Palette,

saving their handles and other data in the

handles structure. The last thing

the Icon Editor

OpeningFcn does is to call uiwait to defer output until the

GUI is complete. When you n eed to close the windows, neither the Color

Palette nor Tool Palette close independently of the Icon Editor because there

is a complicated close sequence involved. Y ou can close all window s using

one of these methods:

• Click the OK button or the Cancel button in the Tool and Color Palette s

andthenclosetheIconEditorWindow.

• Close the Icon Editor window directly.
