TdxAlertWindowImageViewInfo.IsImageAssigned Property

Identifies whether the specified image container or list hosts an image.

Declaration

property IsImageAssigned: Boolean read;

Property Value

Type
Boolean

Remarks

The first overloaded function variant accepts an image container, image list, and the source image’s index within the latter as the AGlyph, AImageList, and AImageIndex parameters, respectively. This variant returns True if either the specified image container is valid and not empty or the image list has an image at the AImageIndex position. The function returns False if finds no image in either container.

The second overloaded function variant returns True only if the specified container exists and its Empty property is False. Otherwise, the function returns False.

The third overloaded function variant returns True only if the specified image list exists, and the AImageIndex value corresponds to an image stored in the list. Otherwise, the function returns False.

Note

The first overloaded IsImageAssigned function variant calls the second and third variants internally to evaluate all parameters.
