PyQtGraph – Clearing Focus of Image View
In this article, we will see how we can clear the focus of the image view object in PyQTGaph. 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.). Widget 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 xmovable region defining the dark/light levels, editable gradient provides a color lookup table. When we click on the image view, focus is shifted on it, it get changed if we click on other widget.
We can create a image view with the help of command given below –
# creating a pyqtgraph image view object imv = pg.ImageView()
In order to do this we use clearFocus method with the image view object
Syntax : imv.clearFocus()
Argument : It takes no argument
Return : It returns None
Below is the implementation
