ProgressDialog#

class pyqtgraph.ProgressDialog(labelText, minimum=0, maximum=100, cancelText='Cancel', parent=None, wait=250, busyCursor=False, disable=False, nested=False)[source]#

Extends QProgressDialog:

  • Adds context management so the dialog may be used in with statements

  • Allows nesting multiple progress dialogs

Example:

with ProgressDialog("Processing..", minVal, maxVal) as dlg:
    # do stuff
    dlg.setValue(i)   ## could also use dlg += 1
    if dlg.wasCanceled():
        raise Exception("Processing canceled by user")
__init__(labelText, minimum=0, maximum=100, cancelText='Cancel', parent=None, wait=250, busyCursor=False, disable=False, nested=False)[source]#
