问题
https://www.tcl.tk/man/tcl8.6/TkCmd/tk_mac.htm#M20 talks about a "System configuration parameter", which is supposed to modify toplevel background on Mac.
How should I set this parameter in Tkinter?
I tried tk_root.option_add("::tk::mac::useThemedToplevel", 1) but it seems to have no effect.
回答1:
I believe that was for MacOS, last released in 1999. When using the 'aqua' theme on Mac OS X, the theme colors can't be changed.
If you need to have a changeable color, use the older widgets, 'frame', 'label', etc. (I have no idea if that's possible in tkinter).
回答2:
Did you try
configuring the toplevel with “-background systemWindowHeaderBackground”
according to the link info?.
I'm a tcl'er so i can't help with that using tkinter. If doesn't works, you could take a look to these other links:
MacWindowStyle : a MacOS X command to create toplevel windows with a variety of appearances
Tk differences on Mac OS X: include some bugs.
(Or can search for more info about Mac in the tcl/tk wiki.)
I hope this help you,
Saludos!
