Dialog Windows

An overview over dialog windows.

Dialogs can be modal, in which case the user is required to provide necessary information before work in the main window can continue, or modeless. Modeless dialogs do not prevent the user from interacting with any of the other windows in the application.

Qt provides a set of ready-made dialogs for file, font, color-selection and more.

PySide6.QtWidgets.QColorDialog	The QColorDialog class provides a dialog widget for specifying colors.
PySide6.QtWidgets.QFileDialog	The QFileDialog class provides a dialog that allows users to select files or directories.
PySide6.QtWidgets.QFontDialog	The QFontDialog class provides a dialog widget for selecting a font.
PySide6.QtWidgets.QInputDialog	The QInputDialog class provides a simple convenience dialog to get a single value from the user.
PySide6.QtWidgets.QMessageBox	The QMessageBox class provides a modal dialog for informing the user or for asking the user a question and receiving an answer.
PySide6.QtWidgets.QProgressDialog	The QProgressDialog class provides feedback on the progress of a slow operation.

Custom dialogs can be easily created by composing regular widgets into a QDialog . These classes are specifically designed for building custom dialogs:

PySide6.QtWidgets.QDialog	The QDialog class is the base class of dialog windows.
PySide6.QtWidgets.QDialogButtonBox	The QDialogButtonBox class is a widget that presents buttons in a layout that is appropriate to the current widget style.
