Re: [platform-swt-dev] Color of the active button / toogle button

[Lars Vogel <lars.vogel@xxxxxxxxxxx>]

Hello Niraj, Leo and Arun,

thanks for the fast answer.

I think I did not use the correct term in my questions. I'm looking for a way to style "selected" buttons, e.g., the ToolItem widget which shows the active perspective or a ToolItem widget in a view bar is toogled. I tried to do hightlight that in the next screenshot.

I also finally found the bug for that: https://bugs.eclipse.org/bugs/show_bug.cgi?id=463358

I there a trick to make this styling already work, or do we have to wait for Bug 463358?

Best regards, Lars

Leo, if I'm not wrong, this works only with GTK3 and not with GTK2 and that would make it even more complicated to support an API that can be meaningfully implemented only on GTK3 and not any of the other supported platforms. The workaround approach suggested by you seems to be the best bet for now and should work on all platforms!

Thanks,
Arun

Hello,

<Leo's thought>
 In SWT there is api to set the background of the button, but there is no api to define the color of the actively selected/focused button.

 However, you could make use of a focus listener and make the actively selected button dark.

 I wrote a little proof of concept snippet:
 https://github.com/LeoUfimtsev/LeoSwtTests/blob/master/src/standaloneTests/LTEST_Button_dark_when_active.java

 To test it you can check out the repo and run the individual java file or copy the snippet and erase line 31. (Btw, Looks nicer with SWT_GTK3=1)

 Attached is a little video of the snippet in action.

 So one potential solution is to include a listener somewhere and when the dark theme is activated, make buttons darker.

<Side note>
  Gtk's CSS theming does support different colors depending on state of the control.
  (Active, selected, unfocused, mouse-over etc...) but this would introduce api change and may not be supported on all platforms.
</Side note>

Thank you
