Window styles

wxPD_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.
wxPD_AUTO_HIDE Causes the progress dialog to disappear from screen as soon as the maximum value of the progress meter has been reached.
wxPD_SMOOTH Causes smooth progress of the gauge control.
wxPD_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.
wxPD_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.
wxPD_ELAPSED_TIME This flag tells the dialog that it should show elapsed time (since creating the dialog).
wxPD_ESTIMATED_TIME This flag tells the dialog that it should show estimated time.
wxPD_REMAINING_TIME This flag tells the dialog that it should show remaining time.

wxProgressDialog::wxProgressDialog

wxProgressDialog(const wxString& title, const wxString& message, int maximum = 100, wxWindow * parent = NULL, int style = wxPD_AUTO_HIDE | wxPD_APP_MODAL)

Constructor. Creates the dialog, displays it and disables user input for other windows, or, if wxPD_APP_MODAL flag is not given, for its parent window only.

Parameters

title

      Dialog title to show in titlebar.

message

      Message displayed above the progress bar.

maximum

      Maximum value for the progress bar.

parent

      Parent window.

style

wxProgressDialog::~wxProgressDialog

~wxProgressDialog()

Destructor. Deletes the dialog and enables all top level windows.

wxProgressDialog::Resume

void Resume()

Can be used to continue with the dialog, after the user had chosen ABORT.

wxProgressDialog::Update

virtual bool Update(int value, const wxString& newmsg = "", bool *skip = NULL)

Updates the dialog, setting the progress bar to the new value and, if given changes the message above it. 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.

Parameters

value

      The new value of the progress meter. It should be less than or equal to the maximum value given to the constructor and the dialog is closed if it is equal to the maximum.
newmsg
      The new messages for the progress dialog text, if it is empty (which is the default) the message is not changed.
skip
      If "Skip" button was pressed since last Update call, this is set to true.

wxProgressDialog::Pulse

virtual bool Pulse(const wxString& newmsg = "", bool *skip = NULL)

Just like Update but makes the gauge control run in indeterminate mode (see wxGauge documentation), sets the remaining and the estimated time labels (if present) to Unknown and moves the progress bar a bit to indicate that some progress was done.
