QNodeEditor.themes

Module containing graphical themes for all node editor elements.

The package comes with two themes:

• DarkTheme: dark theme

• LightTheme: light theme

To set the theme for an entire node scene, use the theme property of a NodeView the scene is displayed in.

Both the NodeEditorDialog and NodeEditor have theme properties that can also be used to set the theme of a node editor.

Examples

To define your own theme, derive a class from Theme and set all the properties:

from PyQt5.QtGui import QColor

class MyTheme(Theme):

    # Editor properties
    editor_color_background = QColor('#ff0000')
    editor_color_grid = QColor('#00ff00')
    font_size = 10
    ...

See the Theme class for all properties that need to be set.

Once you created a theme, use the theme property of a NodeView to apply your theme:

# For a new scene
theme = MyTheme
scene = NodeScene()
view = NodeView(scene, MyTheme)

# For an existing scene
view.theme = MyTheme

# Inside of the node editor widget
editor = NodeEditor()
editor.theme = MyTheme

# Inside of the node editor dialog
dialog = NodeEditorDialog()
dialog.theme = MyTheme

Note that you do not need to create an instance of the theme class.
