In this article, we will see how we can get the children of the image view object in PyQTGaph. The PyQtGraph is a graphics and user interface library for Python that provides functionality commonly required in designing and science applications. Its primary goals are to provide fast, interactive graphics for displaying data (plots, video, etc.), widgets used for display and analysis of image data, implements many features like displaying 2D and 3D image data. For 3D data, a z-axis slider is displayed allowing the user to select which frame is displayed. Displays histogram of image data with a movable region defining the dark/light levels, editable gradient provides a color lookup table. Image view is a group of widgets like it contains a view object, push-button and scroll bars, etc.
We can create an image view object with the help of command given below
# creating a pyqtgraph image view object imv = pg.ImageView()
In order to get children of Image View object, we use children() method with the image view object.
Syntax : imv.children()
Argument : It takes no argument
Return : It returns list
Below is the program to get children of an Image view using PyQTGaph module:
