• to browse multiple error items, included into an exception;
• error kind, native error code, erroneous DB object, etc;
• original SQL command and parameter values leaded to an exception.

For that the dialog hooks TApllication.OnException event. To use the dialog, drop it on a form or a data module. All additional setups are optional. 

IADGUIxErrorDialog has Forms and FMX implementations. Use Provider property to select the desired implementation.

TADGUIxErrorDialog = class(TADGUIxComponent, IADGUIxErrorDialog);
