PyQtGraph - Clearing Focus of Image View

PyQtGraph - Clearing Focus of Image View

To clear the focus of a widget in PyQt or any Qt-based library, you can use the clearFocus() method provided by the QWidget class. In the context of pyqtgraph, if you are working with ImageView, you can call this method on the ImageView instance to remove the focus.

Here's an example showing how to clear the focus of an ImageView in pyqtgraph:

import sys import numpy as np import pyqtgraph as pg from PyQt5.QtWidgets import QApplication, QMainWindow, QPushButton, QVBoxLayout, QWidget class AppDemo(QMainWindow): def __init__(self): super().__init__() self.setWindowTitle('PyQtGraph ImageView Clear Focus') self.setGeometry(100, 100, 800, 600) container = QWidget() layout = QVBoxLayout() # Generate random data for demonstration data = np.random.rand(100, 100) # Create ImageView self.imageView = pg.ImageView() self.imageView.setImage(data) # Add button to clear focus of ImageView btn = QPushButton('Clear Focus of ImageView') btn.clicked.connect(self.clearImageViewFocus) layout.addWidget(self.imageView) layout.addWidget(btn) container.setLayout(layout) self.setCentralWidget(container) def clearImageViewFocus(self): self.imageView.clearFocus() app = QApplication(sys.argv) demo = AppDemo() demo.show() sys.exit(app.exec_())

In this example, an ImageView displays some random data. A QPushButton is added below the ImageView. When the button is clicked, the clearImageViewFocus method is called, which clears the focus from the ImageView.
