impossible to change button's background colour in Linux Mint 17

wxPython Users
1

Hi everyone,

I have a problem with changing the background color of buttons in Linux Mint 17 cinnamon. When I run the script the button stay grey but the panel gets the right colour (see jpg file). I test using python 2.7 / wxpython 3.0 and python 2.7 / wxpython 2.8. the script is working fine with Linux Mint 16 cinnamon. I also test to “compile” the script using pyInstaller under linux Mint 16 and run it under Mint 17 and still working fine under 16 and no change of color under Mint 17.
I post my issue on linux mint forum and get no reply. I tested with several different themes and it’s always the same.

Does someone have an idea on how to fix this problem or give a hint on what I should look into

Thanks in Advance

Regards

Stephan

Instead of using wx.Button, try wx.lib.agw.gradientbutton.GradientButton.
wx.Button uses the native button widget, whereas GradientButton is
painted by portable Python code.

There’s some info that says to use a panel to ensure cross-platform looks the same… do either of the frames look different in this modified file?

Hi Nathan,

Thanks for your suggestion but the buttons are still in grey and for information the 2 frames are identical.

Hi Anders,

With the GradientButton, I’m able to change the background colour (like in the attached file) !!
I’ll check if I could still do all the customization I’ve done with wx.Button.
One difference is with wx.Button the text is in black and in GradientButton it’s white.

thanks for having taking time for the advice.

Any way I’m still wondering with wx.button no more worked.

Regards

If you want something closer to native appearance, you should try wx.lib.buttons.GenButton (and its friends). I’m sure it will do what you ask and will look less out of place than GradientButton.

I would think the reason is that under that version of Linux Mint, the
native button is not allowed to be anything other than the default grey.
Using wxButton means using the native widget, so whatever the OS says is
the final word on what the widgets can look like. In fact, one might argue
that you should not make a button green in that version of Linux Mint,
because you are breaking the native look and feel (some people feel one
ought not to do that).

Hi Andrea,

thanks for the tip. I can change also the background color of a GenButton button and it has effectively a closer look and feel .

Hi,

You post make sense: may be what was allowed in mint 16 (do not follow the theme) are no more allowed in mint 17. I will update this way my post on the Mint forum and see if it ring a bell to someone in the Mint community.

Hi,

I dig this idea of a more authoritative theme and inside the theme, I remove the button.rc file and my button get the background colour I wanted !! (I also lost other aspects like relief) but now I know the cause.

I wonder if this is a GTK+ issue on Mint 17 Cinnamon.

You might want to try the generic button in wx.lib.buttons, that one works for me on LM 17 Cinnamon.

Hi Werner,

Yes, it’s the one I finally use and it fit all my needs.
