On GUI platforms, end users can iconify, or minimize, a modeless window so that it is represented on the screen by only a bitmap icon. Once iconified, the end user can redisplay the window by double-clicking the icon.
To create an iconifiable window, you must associate the window with an icon resource file that exists in your runtime operating system. To do so, set the following window properties:
To prevent end users from iconifying a window, set the Minimize Allowed property to No. (The Icon Filename and Minimized Title properties are ignored if the Minimize Allowed property is set to No.)
Note: On Microsoft Windows, the lookup path for icon files is defined by the UI_ICON environment variable located in the ORACLE.INI file, or in the Microsoft Windows 32-bit registry. When you enter the name of the icon file in the Icon Filename property, do not include the path or .ICO file extension.
