PyQtGraph - Setting Name of Image View

PyQtGraph - Setting Name of Image View

In pyqtgraph, an ImageView provides a widget for displaying and analyzing 2D image data, with functionalities such as histogram adjustments, color mapping, and ROI overlays.

If you want to set a "name" for an ImageView, there isn't a direct method named something like setName(). However, you can do one of the following:

  1. Set the Window Title: If your ImageView is a standalone window or a top-level widget, you can set its window title using the setWindowTitle() method.
  2. Label it with a Label: If you're embedding the ImageView within another layout or widget, you can accompany it with a QLabel to label or "name" it.

Here's an example demonstrating both methods:

import sys import numpy as np import pyqtgraph as pg from PyQt5.QtWidgets import QApplication, QWidget, QVBoxLayout, QLabel app = QApplication(sys.argv) win = QWidget() win.setWindowTitle("ImageView Naming Example") layout = QVBoxLayout() win.setLayout(layout) # Create a random image for demonstration img = np.random.normal(size=(100, 100)) # Method 1: Set the window title for the ImageView imageView1 = pg.ImageView() imageView1.setImage(img) imageView1.setWindowTitle('ImageView 1') layout.addWidget(QLabel("Method 1: Named via setWindowTitle")) layout.addWidget(imageView1) # Method 2: Label the ImageView using QLabel imageView2 = pg.ImageView() imageView2.setImage(img) layout.addWidget(QLabel("Method 2: Named with QLabel - ImageView 2")) layout.addWidget(imageView2) win.show() if __name__ == '__main__': sys.exit(app.exec_())

In this example, we've demonstrated two methods to "name" or label an ImageView. The first method sets the window title if the ImageView is standalone or top-level. The second method uses a QLabel to label or name the ImageView when it's embedded within another widget or layout.
