Progress

The Progress object lets you display and control a standard Directory Opus progress indicator dialog. This object can be obtained from the Command.progress property. The basic steps for using a Progress object are:

Initialize the fundamental properties.
Call the Init method to create the dialog (this creates it but does not show it to the user).
When ready, call the Show method to make the dialog visible.
Call the appropriate methods to initialize the state of the progress bars (by setting the total number of files, total byte size, etc).
As your operation progresses, advance the progress bars using methods like StepFiles and StepBytes.
If appropriate, poll the state of the Abort and other control buttons using GetAbortState.
Call the Hide method and destroy the object when your operation is finished.

Property Name	Return Type	Description
abort	bool	Before calling Init, set to True if the Abort button should be available, or False to disable it.
bytes	bool	Before calling Init, set to True if the dialog should show progress in bytes rather than whole files.
delay	bool	Before calling Init, set to True if the dialog should delay before appearing after the Show method is called. The delay is configured by the user in Preferences.
full	bool	Before calling Init, set to True to enable a "full size" progress indicator with two separate progress bars (one for files and one for bytes).
owned	bool	Before calling Init, set to True if the dialog should be owned by its parent window (the parent is given later, when the dialog is created via the Init method).
pause	bool	Before calling Init, set to True if the Pause button should be available.
skip	bool	Before calling Init, set to True if the Skip button should be available. (This just makes it so the Skip button can be enabled. You must still call EnableSkip later to actually enable it; usually once per file.)

Method Name	Arguments	Return Type	Description
AddFiles	<int:count> <FileSize:bytes>	none	Adds the specified number of files to the operation total. The bytes argument is optional - in a "full size" progress indicator this lets you add to the total byte size of the operation.
ClearAbortState	none	none	Clears the state of the three "control" buttons (Abort / Pause / Skip) so they no longer register as being clicked when GetAbortState is called. If you only want to clear the Skip state, you should normally do that as part of a call to EnableSkip instead. That way you avoid accidentally clearing one of the other states if they become set between you calling GetAbortState and ClearAbortState. In fact, there are very few situations where you should call ClearAbortState.
EnableSkip	<bool:enable> <bool:delay> <bool:clear>	none	Enables the progress dialog's Skip button. For EnableSkip to work, you must have set the skip property to True before the progress dialog was created by the Init method. enable: If True, the Skip button should be enabled; otherwise, it should be disabled. delay (optional, True by default): If True, there will be a short delay before the Skip button is enabled, with it temporarily disabled during the delay; otherwise, the change is instant. See below for why a delay is usually a good idea. clear (optional, True by default): If True, any record of the user pushing the Skip will be cleared, such that GetAbortState no longer returns "s". You usually want this if the progress dialog just moved to a new item. If you support the Skip button, you should normally call EnableSkip once per file, just after you call SetName and similar methods. When used that way, you'll usually want delay and clear to both be True, otherwise clicks of the Skip button intended for one file could affect the file(s) that come after it. For example, if a file takes a long time but then finishes just as the user gets tired of waiting and clicks Skip, the delay and cleared state ensure the unwanted click is harmless.
FinishFile	none	none	Finish the current file. If the byte size of the current file has been set the total progress will be advanced by any remaining bytes.
GetAbortState	<bool:autoPause> <string:wanted> <bool:simple>	string	Polls the state of the three "control" buttons. This returns a string that indicates which, if any, of the three buttons have been clicked by the user. The button states are represented by the following letters in the returned string: a - Abort p - Pause s - Skip If none of the states apply, an empty string is returned. autoPause (optional, False by default): If True, pausing is handled for you automatically. Calls to GetAbortState(True) block while paused and don't return until unpaused; the "p" state is never returned. (Note that clicking Skip or Abort will implicitly unpause the operation.) wanted (optional): If you only want to check one or two of the states, pass a string with their letters. For example, GetAbortState(True,"ap") will test for the Abort and Pause states, but not the Skip one. All states will be checked if the argument is an empty string or not given at all. simple (optional, True by default): If True, the result string will have at most one letter, indicating the most important state. If False, it is possible for multiple states to be indicated at once. For example if Skip and then Pause are clicked, in that order, without the script clearing the Skip state, then GetAbortState(False,"",False) would return "ps" while GetAbortState(False) would return just "p". To clear the state of the three buttons, call the ClearAbortState method. To clear just the Skip button's state, use the EnableSkip method.
Hide	none	none	Hides the progress indicator dialog. The dialog object itself remains valid, and can be redisplayed with the Show method if desired.
HideFileByteCounts	<bool:show>	none	Hides or shows the "XX bytes / YY bytes" string in the progress dialog. You can use this to hide the string if the progress does not indicate a number of bytes (e.g. when it indicates a percentage). Pass True for the show argument to show the string and False to hide it.
Init	<Tab:parent> or <Lister:parent> <string:title>	none	Initializes the dialog. This method causes the actual dialog to be created, although it will not be displayed until the Show method is called. The fundamental properties shown above must be set before this method is called - once the dialog has been created they can not be altered. The parent parameter can be either a Tab or a Lister - this controls which window the dialog is centered over, and if the owned property is set to True which window it is owned by (always appears on top of). If no parent is provided the dialog will not be associated with any particular window. The title parameter specifies the window title of the dialog.
InitFileSize	none	none	Resets the byte count for the current file to zero.
Restart	none	none	Resets the total completed file and byte counts to zero.
SetBytesProgress	<FileSize:bytes>	none	Sets the total completed byte count.
SetFileSize	<FileSize:bytes>	none	Sets the size of the current file.
SetFiles	<int:count>	none	Sets the total number of files.
SetFilesProgress	<int:count>	none	Sets the total completed file count.
SetFromTo	<string:header> <string:from> <string:to>	none	Sets the text at the top of the dialog that indicates the source and destination of an operation. The header argument refers to the string that normally says From: - this allows you to change it in case that term is not applicable to your action. The from argument is the source path, and the to argument (if there is one) is the destination path. Note that if you specify a destination path this always has a To: header appended to it. If you omit the to argument entirely (not just passing an empty string), the destination line will become blank, including the To: header. Use that if you want the second line to be used sometimes but not always. If you never want anything on the second line, use the SetStatus method instead as it will not add space for the extra line.
SetName	<string:name>	none	Sets the name of the current file.
SetPercentProgress	<int:percent>	none	Sets the current progress as a percentage (from 0 to 100).
SetStatus	<string:status>	none	Sets the text displayed in the status line at the top of the dialog. This sets a single-line status message, while SetFromTo can be used to indicate source and destination paths on two lines.
SetTitle	<string:title>	none	Sets the title of the dialog.
SetType	<string:type>	none	Sets the type of the current item - either file or dir.
Show	none	none	Displays the progress indicator dialog. Call this once you have created the dialog using the Init method.
SkipFile	<bool:complete>	none	Skips over the current file. Set the complete argument to True to have the file counted as "complete", or False to count it as "skipped".
StepBytes	<FileSize:bytes>	none	Step the byte progress indicator the specified number of bytes.
StepFiles	<int:count>	none	Step the file progress indicator the specified number of files.
