Generate multifunctional GUIs from classes

magic-class

In magicgui you can make simple GUIs from functions. However, we usually have to create GUIs that are composed of several buttons, and each button is connected with a class method. You may also want a menu bar on the top of the GUI, or sometimes magicgui widgets docked in it.

Decorate your classes with @magicclass and you can use the class both in GUI and from console. They are easy to maintain and minimize the time spent on debugging of GUI implementation.

Magic-class has built-in real-time macro recorder and website-like help widget creator. You can quickly make a reproducible and well-documented GUI without disturbing readability of Pythonic codes.

Magic-class is work in progress. Feel free to report issues, make suggestions and contribute!

Installation

• use pip

pip install magic-class

• from source

git clone https://github.com/hanjinliu/magic-class

Example

Let's make a simple GUI that can load 1-D data and plot it.

from magicclass import magicclass
from pathlib import Path

@magicclass
class PlotData:
    """Load 1D data and plot it."""

    def load(self, path: Path):
        """
        Load file.

        Parameters
        ----------
        path : Path
            File path
        """
        self.data = np.loadtxt(str(path))

    def plot(self):
        """
        Plot data.
        """
        plt.plot(self.data)
        plt.show()

Classes decorated with @magicclass are converted to magicgui's Container widgets. GUI starts with show method.

widget = PlotData(title="Title")
widget.show()

You can continue analysis in console.

widget.plot()

magic-class is also compatible with napari. You can add them to viewers as dock widgets.

import napari
viewer = napari.Viewer()
viewer.window.add_dock_widget(widget)

After you pushed "load" → "plot" you can make an executable Python script like below.

print(widget.macro)

ui = PlotData(title='Title')
ui.load(path=r'...')
ui.plot()

To make nicer GUI, you can also nest magic-class:

@magicclass
class PlotData:
    @magicclass
    class Menu: ...

add menus with @magicmenu decorator:

@magicclass
class PlotData:
    @magicmenu
    class File: ...
    @magicmenu
    class Edit: ...

add context menu with @magiccontext decorator:

@magicclass
class PlotData:
    @magiccontext
    class context: ...
        def Copy(self): ...
        def Paste(self): ...

directly integrate magicgui and its widgets:

@magicclass
class PlotData:
    line = LineEdit()
    @magicgui
    def load(self, path: Path): ...

... and so on.
