  • opts# (renderdoc.ReplayOptions) – The options controlling how the capture should be replayed.

  • origFilename# (str) – The original filename, if the capture was copied remotely for replay.

  • temporary# (bool) – True if this is a temporary capture which should prompt the user for either save or delete on close.

  • local# (bool) – True if captureFile refers to a file on the local machine.

MarkMessagesRead()

Mark all messages as read, resets UnreadMessageCount() to 0.

OpenRGPProfile(filename)

Sets the path to the RGP profile to use with GetRGPInterop(), launches RGP and opens an interop connection. This function will block (with a progress dialog) until either an error is encountered or else the connection is successfully established.

This could be newly created, or extracted from an embedded section in the RDC.

Returns

The current replay manager.

Return type

ReplayManager

ResourceNameCacheID()

Returns an index that can be used to cache the results of resource naming.

In some cases (e.g. formatting in widgets) there might be high frequency fetches to names without an easy way to force a refresh on a rename. Instead, the index here can be cached and compared each time to see if any names have changed.

The index starts at 1, so initialising an internal cache to 0 will cause the first check to be considered out of date

Returns

An incrementing index that can be used as a quick check if any names have changed.

Return type

int

SaveCaptureTo(captureFile)

Saves the current capture file to a given path.

If the capture was temporary, this save action means it is no longer temporary and will be treated like any other capture.

Any modifications to the capture (see GetCaptureModifications()) will be applied at the same time.

Parameters

captureFile# (str) – The path to save the capture file to.

Returns

True if the save operation was successful.

Return type

bool

Parameters

  • key# (str) – The name of the notes field to set.

  • contents# (str) – The new contents to assign to that field.

SetResourceCustomName(id, name)

Set a custom name for a resource.

This allows an override to the name returned by GetResourceName(), most useful when there are no pre-existing debug names specified in the capture.

To remove a custom name that has been set previously, specify the empty string as the name. Then the custom name will be removed, and instead GetResourceName() will fall back to returning any name fetched from the capture.

Parameters

  • id# (renderdoc.ResourceId) – The ID of the resource to name.

  • name# (str) – The name to provide, or an empty string to remove any previous custom name.

Replay Manager

class qrenderdoc.ReplayManager

A manager for accessing the underlying replay information that isn’t already abstracted in UI side structures. This manager controls and serialises access to the underlying ReplayController, as well as handling remote server connections.

This manager is retrieved by calling CaptureContext.Replay().

InvokeCallback(controller)

Not a member function - the signature for any InvokeCallback callbacks.

Parameters

controller (renderdoc.ReplayController) – The controller to access. Must not be cached or used after the callback returns.

DirectoryBrowseCallback(path, entries)

Not a member function - the signature for any DirectoryBrowseCallback callbacks.

Parameters

  • path (str) – The path that was queried for.

  • entries (List[renderdoc.PathEntry]) – The entries underneath the path, as relevant.

AsyncInvoke(tag, method)
AsyncInvoke(method) → None

Make a tagged non-blocking invoke call onto the replay thread.

This tagged function is for cases when we might send a request - e.g. to pick a vertex or pixel - and want to pre-empt it with a new request before the first has returned. Either because some other work is taking a while or because we’re sending requests faster than they can be processed.

The manager processes only the request on the top of the queue, so when a new tagged invoke comes in, we remove any other requests in the queue before it that have the same tag.

Parameters

  • tag# (str) – The tag to identify this callback.

  • method# (InvokeCallback) – The function to callback on the replay thread. Callback function signature must match InvokeCallback().

BlockInvoke(m)

Make a blocking invoke call onto the replay thread.

Parameters

method# (InvokeCallback) – The function to callback on the replay thread. Callback function signature must match InvokeCallback().

CancelReplayLoop()

Cancels the active replay loop. See ReplayLoop().

ConnectToRemoteServer(host)

Connect to a remote server.

Parameters

host# (RemoteHost) – The host to connect to.

Returns

Whether or not the connection was successful.

Return type

renderdoc.ResultDetails

CopyCaptureFromRemote(remotepath, localpath, window)

Copy a capture from the remote host to the local machine.

Parameters

  • remotepath# (str) – The path on the remote server to copy from.

  • localpath# (str) – The path on the local machine to copy to.

  • window# (QWidget) – A handle to the window to use when showing a progress bar.

CopyCaptureToRemote(localpath, window)

Copy a capture from the local machine to the remote host.

Parameters

  • localpath# (str) – The path on the local machine to copy from.

  • window# (QWidget) – A handle to the window to use when showing a progress bar.

Returns

The path on the local machine where the file was saved, or empty if something went wrong.

Return type

str

CurrentRemote()

Retrieves the host that the manager is currently connected to.

Returns

The host connected to, or an invalid RemoteHost if no connection is active.

Return type

RemoteHost

DeleteCapture(capturefile, local)

Delete a capture file, whether local or remote.

Parameters

  • capturefile# (str) – The path to the file.

  • local# (bool) – True if the file is on the local machine.

DisconnectFromRemoteServer()

Disconnect from the server the manager is currently connected to.

ExecuteAndInject(exe, workingDir, cmdLine, env, capturefile, opts)

Launch an application and inject into it to allow capturing.

This happens either locally, or on the remote server, depending on whether a connection is active.

Parameters

  • exe# (str) – The path to the executable to run.

  • workingDir# (str) – The working directory to use when running the application. If blank, the directory containing the executable is used.

  • cmdLine# (str) – The command line to use when running the executable, it will be processed in a platform specific way to generate arguments.

  • env# (List[renderdoc.EnvironmentModification]) – Any environment changes that should be made when running the program.

  • capturefile# (str) – The location to save any captures, if running locally.

  • opts# (renderdoc.CaptureOptions) – The capture options to use when injecting into the program.

Returns

The ExecuteResult indicating both the status of the operation (success or failure) and any reason for failure, or else the ident where the new application is listening for target control if everything succeeded.

Return type

renderdoc.ExecuteResult

GetCaptureAccess()

Retrieves the capture access handle for the currently open file.

Returns

The file handle active, or None if no capture is open.

Return type

renderdoc.CaptureAccess

GetCaptureFile()

Retrieves the capture file handle for the currently open file, if it is available.

If the capture is not open locally this will not be available, and only GetCaptureAccess() will be usable.

Returns

The file handle active, or None if no capture is open or the capture is only available remotely.

Return type

renderdoc.CaptureFile

GetCurrentProcessingTime()

Return the amount of time that the currently active command on the replay thread has been executing for.

This can be used to identify if a command is long-running to display a progress bar or notification.

Returns

The time in seconds that the current command has been executing for, or 0.0 if no command is executing.

Return type

float

GetHomeFolder(synchronous, callback)

Query the remote host for its home directory.

If a capture is open, the callback will happen on the replay thread, otherwise it will happen in a blocking fashion on the current thread.

Parameters

  • synchronous# (bool) – If a capture is open, then True will use BlockInvoke() to call the callback. Otherwise if False then AsyncInvoke() will be used.

  • callback# (DirectoryBrowseCallback) – The function to callback on the replay thread. Callback function signature must match DirectoryBrowseCallback().

GetRemoteSupport()

Retrieve a list of drivers that the current remote server supports.

Returns

The list of supported replay drivers.

Return type

List[str]

ListFolder(path, synchronous, callback)

Query the remote host for the contents of a path.

If a capture is open, the callback will happen on the replay thread, otherwise it will happen in a blocking fashion on the current thread.

Parameters

  • path# (str) – The path to query the contents of.

  • synchronous# (bool) – If a capture is open, then True will use BlockInvoke() to call the callback. Otherwise if False then AsyncInvoke() will be used.

  • callback# (DirectoryBrowseCallback) – The function to callback on the replay thread. Callback function signature must match DirectoryBrowseCallback().

PingRemote()

Ping the remote server to ensure the connection is still alive.

ShutdownServer()

Shutdown the server the manager is currently connected to.

RGP Interop Control

class qrenderdoc.RGPInterop

Controlling interface for interop with RGP tool.

HasRGPEvent(eventId)

Return true if the given eventId has and equivalent in RGP.

Parameters

eventId# (int) – The eventId to query for.

Returns

True if there is an equivalent. This only confirms the equivalent exists, not that it will be selectable in all cases.

Return type

bool

SelectRGPEvent(eventId)

Select the given eventId equivalent in RGP.

Parameters

eventId# (int) – The eventId to query for.

Returns

True if the selection request succeeded. This only confirms the request was sent, not that the event was selected in RGP.

Return type

bool

CaptureViewer Interface

class qrenderdoc.CaptureViewer

An interface implemented by any object wanting to be notified of capture events.

OnCaptureClosed()

Called whenever a capture is closed.

OnCaptureLoaded()

Called whenever a capture is opened.

OnEventChanged(eventId)

Called whenever the effective current event changes.

Parameters

eventId# (int) – The new eventId.

OnSelectedEventChanged(eventId)

Called whenever the current selected event changes. This is distinct from the actual effective current event, since for example selecting a marker region will change the current event to be the last event inside that region, to be consistent with selecting an item reflecting the current state after that item.

The selected event shows the eventId that was actually selected, which will usually but not always be the same as the current effective eventId.

The distinction for this callback is not normally desired, instead use OnEventChanged() to be notified whenever the current event changes. The API inspector uses this to display API events up to a marker region.

Parameters

eventId# (int) – The new eventId.

Utilities

class qrenderdoc.DockReference(value)

Specifies the relationship between the existing dock window and the new one when adding a new dock window or moving an existing dock window.

NoArea

The existing dock window is not used, the new window is hidden.

AddTo

The new dock window is placed in a tab set with the existing dock window.

LeftOf

The new dock window is placed to the left of the existing dock window, at a specified proportion.

RightOf

The new dock window is placed to the right of the existing dock window, at a specified proportion.

TopOf

class qrenderdoc.CaptureModifications(value)

Details any changes that have been made to a capture in the UI which can be saved to disk but currently aren’t. Note that detection is conservative - e.g. if a change is made, then cancelled out by reversing the change, this will still count as ‘modified’ even if the end result is the same data. In that sense it’s analogous to adding and then deleting some characters in a text editor, since there is no actual undo system.

This is a bitmask, so several values can be present at once.

NoModifications

Fixed value of 0 indicating no modifications have been made.

Renames

One or more resources have been given a custom name which hasn’t been saved.

Bookmarks

Event bookmarks have been added or removed.

Notes
