Forms in OpenLP are made up of two classes. One class holds all the graphical elements, like buttons and lists, and the
|
|
other class holds all the functional code, like slots and loading and saving.
|
|
|
|
The first class, commonly known as the **Dialog** class, is typically named ``Ui_<name>Dialog``. It is a slightly
|
|
modified version of the class that the ``pyuic5`` command produces from Qt5's .ui file. Typical modifications will be
|
|
converting most strings from "" to '' and using OpenLP's ``translate()`` function for translating strings.
|
|
|
|
The second class, commonly known as the **Form** class, is typically named ``<name>Form``. This class is the one which
|
|
is instantiated and used. It uses dual inheritance to inherit from (usually) QtWidgets.QDialog and the Ui class
|
|
mentioned above, like so::
|
|
|
|
class AuthorsForm(QtWidgets.QDialog, Ui_AuthorsDialog):
|
|
|
|
def __init__(self, parent=None):
|
|
super(AuthorsForm, self).__init__(parent)
|
|
self.setupUi(self)
|
|
|
|
This allows OpenLP to use ``self.object`` for all the GUI elements while keeping them separate from the functionality,
|
|
so that it is easier to recreate the GUI from the .ui files later if necessary.
