Description

UIcore is a base class that manages core resources that all UI objects need. It cannot be instantiated separately.

Subobjects

&visible

Boolean. A flag that indicates whether the widget is visible on the screen. 1=visible; 0=not visible. The default is 1 (visible).This value is normally controlled by the widget's or widget parent's instance and update functions. For example, the UIoption widget that creates menus would set its child widget's visibility to 1 when a user selects a menu item. In a UIdialog, OK would change visibility to 0, removing the dialog, while Apply would leave it set at 1.This value is read/write.

&active

UIwindow class attributes

pixmap

Pixmap resources.

color

Foreground and background color attributes. Inherited from UIcolor.

fontAttributes

Font family attributes. Inherited from UIfontAttributes.

fontList (on Unix systems only)

String. A font list string specified in the XFLD format (X Logical Font Description) that describes a font to be used for the text strings associated with this object. The specified font must match one of those specified in the fonts.v file (see Adding fonts to AVS/Express  in the Using AVS/Express manual).
