When we launch the example, it will display a frame window with text field. The click of the ellipsis button (…) will open the file open dialog. From the displayed dialog, we can browse through the folders of the PC and pick a specific file on the folder structure. Our example will display the selected file in the text field. This happens only when the user clicks the Open button. When the user clicks the Cancel button, it will not show the picked file in the text field.
