Dialog Item Scan
The Image Scan Progress dialog reports progress while DiskImageTool examines loaded disk images to populate a filter. It appears automatically when a scan is started and closes automatically when the scan completes.
The dialog is not opened directly. It is shown by commands that trigger an image scan, for example:
- Menu: Filters -> Scan Images (and the various sub-options in that menu).
Image scans traverse the workspace and inspect each loaded image to build or refresh a filter set. Depending on the filter, scanning can include reading the boot sector, walking the file system, computing checksums, or collecting other image-wide information.
The dialog shows a single progress line in the form:
Scanning... nn.n%
where Scanning is replaced by a label specific to the scan that was requested (for example, Scanning for modifications).
The window title is likewise set by the caller to describe the current scan.
Requests cancellation of the scan.
- Closing the dialog (for example, clicking the close icon) has the same effect as Cancel.
- Cancellation is cooperative: the scanner checks for the request at regular intervals and stops at the next safe opportunity.
- If the scan is cancelled, the related filter is left in whatever state it reached before cancellation.
- The dialog is modal; other interaction with the main window is blocked while the scan runs.
- If a scan encounters an error, the error is reported back to the caller after the dialog closes.
