Such names are matched against the optiondatabase, so your application can pick up theuser’s configuration preferences (such as colors) byclass name. For example, you might design a seriesof popups called “screamers,” and set them allup with class_="Screamer". Then you can put aline in your option database like this:*Screamer*background:and then, if you use the .option_readfile()method to read your option database, all widgetswith that class name will default to a red background.This option is named class_ because inPython class is a reserved word.cursorThe cursor that appears when the mouse is in thiswindow.heightWindow height in pixels.relief One of: FLAT (the default), SUNKEN, RAISED,GROOVE, or RIDGE.widthWindow width in pixels.These methods are available for top-level windows:.aspect ( n min , d min , n max , d max )Constrain the root window’s width:length ratio to the range [n min =d min ; n max =d max ]..deiconify()If iconified, expand..geometry ( newGeometry=None )Set the window geometry.
