Viewer
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.
bottom
int
Returns the bottom coordinate of the viewer window.
desktop
string
Returns the ID of the virtual desktop this viewer is on.
foreground
bool
Returns True if the viewer is currently the foreground (active) window in the system.
imagesize
object:Rect
Returns a Rect object representing the size of the currently displayed image (native size, ignoring any scaling).
index
int
Returns the index of the currently viewed image within the viewer's list of files.
lastactive
bool
Returns True if the viewer is the most recently active viewer.
left
int
Returns the left coordinate of the viewer window.
parentlister
object:Lister
Returns a Lister object representing the Lister that launched the viewer (if there was one, and if it still exists) or, if viewer re-use is enabled, last sent files to the viewer.
There may be a parentlister object in situations where there is no longer a parenttab object. For example, if the tab was closed since the viewer opened, or if a request to open an image from something other than a folder tab was received by the viewer, then there will no longer be a parenttab but the parentlister property will persist.
This property is a snapshot of the situation when the Viewer scripting object was created; it won't change in reaction to script actions.
parentlisterlinked
bool
Returns True if the viewer is in Lister-Linked mode with the parent Lister. This means the viewer acts like a detached preview pane, displaying each file as it is selected in the Lister.
This property is a snapshot of the situation when the Viewer scripting object was created; it won't change in reaction to script actions.
parenttab
object:Tab
Returns a Tab object representing the tab that launched the viewer (if there was one, and if it still exists) or, if viewer re-use is enabled, last sent files to the viewer.
If you want the Lister rather than the Tab, the parentlister property (above) should be used, as it is more persistent. Additionally, do not assume parenttab is still the active tab in the Lister; query the Lister object if you need that.

right
int
Returns the right coordinate of the viewer window.
selection
object:Rect
Returns a Rect object representing the current selection area (if any) of the image. If there's no selection the rectangle will be empty.
title
string
Returns or sets the title bar string for the viewer window.
You can use several special "tokens" in the title string to insert various pieces of information:
%P
full path of the currently viewed image
%N
name of the current displayed image
%R
drive root of the current image
%E
displays * if the image's metadata has been modified and not saved
%I
current image's index (number) in the list of images
%O
total number of images in the list
%W
width of the current image
%H
height of the current image
%D
depth of the current image (bits per pixel)
%M
current image's dimensions
%S
file size on disk
%F
folder name
%T
original title (useful for simply adding a prefix or suffix to the title)
%%%%%%
insert a literal % character
top
int
Returns the top coordinate of the viewer window.

Method Name
Arguments
Return Type
Description
AddFile
<string:filepath> <int:index>
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.
IsOnCurrentDesktop
none
bool
Returns True if the viewer is on the current virtual desktop.
MoveToDesktop
<string:desktop>
bool
Moves the viewer window to the specified virtual desktop. Returns True if successful.
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 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.
