wx.ProgressDialog(GenericProgressDialog)¶Possible constructors:
ProgressDialog(title, message, maximum=100, parent=None,
style=PD_APP_MODAL|PD_AUTO_HIDE)
If supported by the platform this class will provide the platform’s native progress dialog, else it will simply be the GenericProgressDialog.
__init__(self, title, message, maximum=100, parent=None, style=PD_APP_MODAL|PD_AUTO_HIDE)¶title (string) –
message (string) –
maximum (int) –
parent (wx.Window) –
style (int) –
GetClassDefaultAttributes(variant=WINDOW_VARIANT_NORMAL)¶variant (WindowVariant) –
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.
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.
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.
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.
newmsg (string) –
tuple
( 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.
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 if newmsg is longer than the currently shown message, the dialog will be automatically made wider to account for it. However if the new message is shorter than the previous one, the dialog doesn’t shrink back to avoid constant resizes if the message is changed often. To do this and fit the dialog to its current contents you may call Fit explicitly. However the native MSW implementation of this class does make the dialog shorter if the new text has fewer lines of text than the old one, so it is recommended to keep the number of lines of text constant in order to avoid jarring dialog size changes. You may also want to make the initial message, specified when creating the dialog, wide enough to avoid having to resize the dialog later, e.g. by appending a long string of unbreakable spaces ( String (L’\u00a0’, 100)) to it.
value (int) – The new value of the progress meter. It should be less than or equal to the maximum value given to the constructor.
newmsg (string) – The new messages for the progress dialog text, if it is empty (which is the default) the message is not changed.
tuple
( 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 doing it.
It always returns False if the Cancel button is not shown at all.
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.
bool
New in version 2.9.1.
