DOpus

The DOpus object is one of the two global script objects provided by Opus, and is available to all scripts. It provides various helper methods, and collections that let you access things like Listers and toolbars.

Method Name

Arguments

Return Type

Description

ClearOutput

none

none

Clears the script output log.

Create

none

object:DOpusFactory 

Creates and returns a new DOpusFactory object, which can be used to create various lightweight helper objects like Blob, Map and Vector.

Delay

<int:time>

none

Delays for the specified number of milliseconds before returning.

Dlg

none

object:Dialog

Creates a new Dialog object, that lets you display dialogs and popup menus.

Note: Scripts should not usually use this when responding to events triggered by toolbars or folder tabs. The Dialog returned by DOpus.Dlg will not have its parent window configured. Most scripting events provide you an object which can either create a pre-configured Dialog or which includes a SourceTab property or similar which can do the same. In almost all situations you should use those instead.

DPI

none

object:DPI 

Creates the DPI helper object which assists when dealing with different system scaling settings (e.g. high-DPI monitors).

FSUtil

none

object:FSUtil 

Creates a new FSUtil object, that provides helper methods for accessing the file system.

GetClip

none

or <string:type>

string
or collection:Item 

Retrieves the current contents of the system clipboard, if it contains either text or files.

You can control the returned type by passing either "text" or "files" for the <type> argument - Opus will convert to the requested type if possible.

If <type> is not specified the contents will be returned in their native format.

GetClipFormat

none

string

Returns a string indicating the native format of the clipboard contents - "text", "files" or an empty string in any other case.

GetQualifiers

none

string

Returns a string indicating which qualifier keys are currently held down. If none are held down, the string will be "none". Otherwise, the string can contain any or all of the following, separated by commas: "shift", "ctrl", "alt", "lwin", "rwin".

Note that many events pass you a similar list of qualifiers. If you are passed a list of qualifiers, you should generally use that list rather than call DOpus.GetQualifiers.

For example, script commands are passed a Func object with a qualifiers property. That property will tell you which keys were held down when the command was triggered, and that may be different to the keys held down a few seconds later. When the user clicks a button to run a command, they normally expect the command to use the keys they held when they clicked, not the keys they are touching later while waiting for it to finish.

Similarly, events like OnBeforeFolderChange will often pass you an object like BeforeFolderChangeData containing a qualifiers property which indicates key state when the event was triggered. You should normally use that instead of calling DOpus.GetQualifiers.

If you do call DOpus.GetQualifiers, you would normally want to call it as soon as possible and then store the result, so there is less time for the user to let go of a key after triggering your script.

If you call DOpus.GetQualifiers more than once, you may get a different result each time, due to keys being pushed or released between calls. Call it once and store the result if you need to do multiple checks and need them to be consistent. This does not generally affect the qualifiers properties mentioned earlier, since they are usually stored snapshots of the key state.

LoadImage

<string:filename> or <object:Blob>
[<int:width>]
[<int:height>]

[<bool:alpha>]

object:Image 

Loads an image file from the specified external file. You can optionally specify the desired size to load the image at, and whether the alpha channel (if any) should be loaded or not.

 

You can also provide a Blob object containing the image data instead of a filename. 
 

The returned Image object can be given as the value of the Control.label property for a static control in a script dialog (when that control is in "image" mode). You can also assign as to the icon property of a Dialog object to specify a custom window icon for your script dialog.

LoadThumbnail

<string:filename>

[<int:timeout>]
[<int:width>]
[<int:height>]

[<string:flags>]

object:Image 
or

bool (False)

Extracts a thumbnail from the specified external file. You can optionally specify a timeout (in milliseconds) and the desired size to load the thumbnail at.

 

The optional flags value supports the following flags (supplied as a string):

 

i - prevents Opus from waiting for thumbnails that may take some time to generate, and instead returns a large icon if the thumbnail can't be generated immediately.

c - modifies the i flag to only apply to Cloud storage folders.
 

If loading fails (or the timeout expires before the thumbnail could be generated) this method returns False.
 

The returned Image object can be given as the value of the Control.label property for a static control in a script dialog (when that control is in "image" mode). You can also assign as to the icon property of a Dialog object to specify a custom window icon for your script dialog.

Output

<string:text>
[<bool:error>]
[<bool:timestamp>]

none

Prints the specified text string to the script output log (found in the Utility Panel,  the CLI in script mode, the Rename dialog and the Command Editor in script mode).

If the second argument is provided and set to True, the message will be displayed as an error. This means the text will be displayed in red and if no log windows are currently open, a warning icon will flash in the Lister status bar to alert the user of an error condition.

 

If the optional third argument is provided and set to True then the log message will have a timestamp prepended to it. Timestamps only appear in the utility panel, not in places like the Command Editor's output panel. Error messages always get timestamps so if the second argument is True then the third is ignored

ReloadScript

<string:file>

none

Causes Opus to reload and reinitialize the specified script. You must provide the full pathname of the script on disk (if a script add-in wants to reload itself you can pass the value of the Script.file property).

SetClip

<string:text>
or collection:Item
or none

none

Places the specified text, or Item collection (or Vector of Item objects) on the system clipboard. If called with no arguments the clipboard will be cleared.

Toolbars

<string:type>

object:Toolbars 

Returns a Toolbars object which lets you enumerate all defined toolbars (whether they are currently open or not).

 

You can restrict this object to only return in-use toolbars by specifying the optional type parameter - specify "listers" to only return toolbars currently turned on in a Lister, and "docks" to only return toolbars that are currently floating.

TypeOf

any

string

Returns a string indicating the type of an object or variable.
