This class represents a dialog that shows a short message and a progress bar.
Optionally, it can display ABORT
and SKIP
buttons, and the elapsed, remaining and estimated time for the end of the progress.
This class provides a generic implementation of the progress dialog. If the platform has a native progress dialog available then it will be accessible using the ` wx.ProgressDialog ` class, otherwise it will essentially be the same as this class.
Note that you must be aware that wx.ProgressDialog internally calls wx.EventLoopBase.YieldFor
with wxEVT_CATEGORY_UI
and wxEVT_CATEGORY_USER_INPUT
and this may cause unwanted re-entrancies or the out-of-order processing of pending events (to help preventing the last problem if you’re using wx.ProgressDialog in a multi-threaded application you should be sure to use ThreadEvent for your inter-threads communications).
This class supports the following styles:
wx.PD_APP_MODAL
: Make the progress dialog modal. If this flag is not given, it is only “locally” modal - that is the input to the parent window is disabled, but not to the other ones.wx.PD_AUTO_HIDE
: Causes the progress dialog to disappear from screen as soon as the maximum value of the progress meter has been reached. If this style is not present, the dialog will become a modal dialog (see wx.Dialog.ShowModal
) once the maximum value has been reached and wait for the user to dismiss it.wx.PD_SMOOTH
: Causes smooth progress of the gauge control (uses a wx.Gauge with the GA_SMOOTH
style).wx.PD_CAN_ABORT
: This flag tells the dialog that it should have a “Cancel” button which the user may press. If this happens, the next call to Update
will return False
.wx.PD_CAN_SKIP
: This flag tells the dialog that it should have a “Skip” button which the user may press. If this happens, the next call to Update
will return True
in its skip parameter.wx.PD_ELAPSED_TIME
: This flag tells the dialog that it should show elapsed time (since creating the dialog).wx.PD_ESTIMATED_TIME
: This flag tells the dialog that it should show estimated time.wx.PD_REMAINING_TIME
: This flag tells the dialog that it should show remaining time.__init__ |
Constructor. |
GetMessage |
Returns the last message passed to the Update function; if you always passed “” to Update then the message set through the constructor is returned. |
GetRange |
Returns the maximum value of the progress meter, as passed to the constructor or NOT_FOUND if the dialog has no progress bar. |
GetValue |
Returns the last value passed to the Update function or NOT_FOUND if the dialog has no progress bar. |
Pulse |
Like Update but makes the gauge control run in indeterminate mode. |
Resume |
Can be used to continue with the dialog, after the user had clicked the “Abort” button. |
SetRange |
Changes the maximum value of the progress meter given in the constructor. |
Update |
Updates the dialog, setting the progress bar to the new value and updating the message if new one is specified. |
WasCancelled |
Returns True if the “Cancel” button was pressed. |
WasSkipped |
Returns True if the “Skip” button was pressed. |

GenericProgressDialog
(Dialog)¶Possible constructors:
GenericProgressDialog(title, message, maximum=100, parent=None,
style=PD_AUTO_HIDE|PD_APP_MODAL)
This class represents a dialog that shows a short message and a progress bar.
__init__
(self, title, message, maximum=100, parent=None, style=PD_AUTO_HIDE|PD_APP_MODAL)¶Constructor.
Creates the dialog, displays it and disables user input for other windows, or, if PD_APP_MODAL
flag is not given, for its parent window only.
Parameters: |
|
---|
GetMessage
(self)¶Returns the last message passed to the Update
function; if you always passed “” to Update
then the message set through the constructor is returned.
Return type: | string |
---|
New in version 2.9.0.
GetRange
(self)¶Returns the maximum value of the progress meter, as passed to the constructor or NOT_FOUND
if the dialog has no progress bar.
Return type: | int |
---|
New in version 2.9.0.
GetValue
(self)¶Returns the last value passed to the Update
function or NOT_FOUND
if the dialog has no progress bar.
Return type: | int |
---|
New in version 2.9.0.
Pulse
(self, newmsg="")¶Like Update
but makes the gauge control run in indeterminate mode.
In indeterminate mode the remaining and the estimated time labels (if present) are set to “Unknown” or to newmsg (if it’s non-empty). Each call to this function moves the progress bar a bit to indicate that some progress was done.
Parameters: | newmsg (string) – |
---|---|
Return type: | tuple |
Returns: | ( bool, skip ) |

Resume
(self)¶Can be used to continue with the dialog, after the user had clicked the “Abort” button.
SetRange
(self, maximum)¶Changes the maximum value of the progress meter given in the constructor.
This function can only be called (with a positive value) if the value passed in the constructor was positive.
Parameters: | maximum (int) – |
---|
New in version 2.9.1.
Update
(self, value, newmsg="")¶Updates the dialog, setting the progress bar to the new value and updating the message if new one is specified.
Returns True
unless the “Cancel” button has been pressed.
If False
is returned, the application can either immediately destroy the dialog or ask the user for the confirmation and if the abort is not confirmed the dialog may be resumed with Resume
function.
If value is the maximum value for the dialog, the behaviour of the function depends on whether PD_AUTO_HIDE
was used when the dialog was created. If it was, the dialog is hidden and the function returns immediately. If it was not, the dialog becomes a modal dialog and waits for the user to dismiss it, meaning that this function does not return until this happens.
Notice that you may want to call Fit
to change the dialog size to conform to the length of the new message if desired. The dialog does not do this automatically.
Parameters: |
|
---|---|
Return type: | tuple |
Returns: | ( bool, skip ) |
WasCancelled
(self)¶Returns True
if the “Cancel” button was pressed.
Normally a Cancel button press is indicated by Update
returning False
but sometimes it may be more convenient to check if the dialog was cancelled from elsewhere in the code and this function allows to do it.
It always returns False
if the Cancel button is not shown at all.
Return type: | bool |
---|
New in version 2.9.1.
WasSkipped
(self)¶Returns True
if the “Skip” button was pressed.
This is similar to WasCancelled
but returns True
if the “Skip” button was pressed, not the “Cancel” one.
Return type: | bool |
---|
New in version 2.9.1.
