The Viewer object represents a standalone image viewer. A collection of Viewer objects is returned by the Viewers object, which is obtainable via the DOpus.viewers property. For functions launched from within a viewer (e.g. from its toolbar), the current Viewer object is provided by the ClickData.func.viewer property.

Arguments |
Return Type |
Description |
---|---|---|---|
AddFile |
<string:filepath> |
none |
Adds the specified file to the viewer's current list of files. You can either pass a string or a Path object to indicate the file to add to the list. By default the file will be added to the end of the list, unless you specify a 0-based index as the second argument. |
Command |
<string:command> or <Command:command> |
none |
Runs a command in the context of this viewer window. You can either pass a string or a Command object.
If the argument you pass is a string then it can only be a viewer command argument as documented for the Show VIEWERCMD command. For example, Command(“next”) would run the Show VIEWERCMD=next command in the context of this viewer.
If you pass a Command object then all commands (internal or external) can be used. |
RemoveFile |
<int:index> or <string:filepath> |
none |
Removes the specified file from the viewer's current list of files. You can either pass the 0-based index of the file to remove, or the filepath (either as a string or a Path object). |
SetTaskbarGroup |
<string:group> |
bool |
Used to change how the viewer window is grouped with other Opus windows on the taskbar. Specify a group name to move the window into an alternative group, or omit the group argument to reset back to the default group. If one or more windows are moved into the same group, they will be grouped together, separate from other the default group. This only works on Windows 7 and above, and only when taskbar grouping is enabled. Group names are limited to 103 characters and will be truncated if longer. Spaces and dots in group names are automatically converted to underscores. Returns true on success. |
