The existing requirements need to remove the translucency and change the background color or picture.
There is a maximized parameter in Ext.window.Window, which can be initialized to display the form in the maximum state, then set the header to false, and set the corresponding CSS property in bodyStyle. If you need to add an image, you can use background-image in the css of bodyStyle
