Are there more changes to be made for this open bug report?

I pushed the changeset to the stable branch here:

In the meantime I managed to get the gtk2 style to work via qt5c (breaking the style selection in the Octave properties on the way).
It looks like gtk2 uses the border property to style the buttons. The border seems to cover the background color completely.
The attached patch sets a manual border for the pushbutton objects. But the result doesn't look very good. And it also makes all other styles look worse...

My vote for pushing the changeset. Afterwards, we can concentrate on fixing the bug for gtk.

On my system (Ubuntu 18.04, GNOME 3.26), the styles "default" and "gtk2" behave identically, which also implies that the patch does not work for "default" for me. With your configuration, I would have expected that "gtk2" is already available for you and/or that the patch is not working for your "default" style.

Should we push the latest changeset because it fixes the regression on Windows? We could still push a follow-up patch for gtk2 when it is ready.
Or do you think you are close to having a solution for the "gtk2" style as well?

Do you know if it is possible to add gtk2 to the available styles on my Ubuntu 18.10 with GNOME 3.30.1?

@Markus: Unfortunately, this does not work for the style "gtk2" (but for any other style available on my system). I have also made some tests with

but without success.

The attached patch works for me with Qt styles "Fusion", "Windows" and "WindowsVista".

@Torsten: If I correctly understand the css, the change should remove any background image. Could you please try whether this works for you with "gtk2"? (I used Guillaume's test from comment #8.)

This is a regression in 5.0. Tagging appropriately.

To make it easier to follow, I am reposting the (incomplete) patch from bug #53174 which uses stylesheets for setting the button background color here.

Also a link to stackoverflow with an answer that might help for the issue with gtk2:

As a comparison point, I attach a screenshot of how the figure created with comment #8 is displayed with current Octave dev and Matlab R2018b on openSUSE 15.0.

One difference in behavior that I observe is that for checkbox and radiobutton uicontrols, their state is changed whenever one clicks anywhere within them with Matlab while one has to click on the text or the little square or circle with Octave.

Reopened since the issue is still present on other platforms and requires a more general approach like using style sheets instead of setPalette (see discussion and first patches in bug #53174).

I think that position of controls is purely a toolkit (Qt vs ??) difference that we probably don't have much control over.

I see the same for slider color, and it looks like it ignores colors set via the palette - any examples I have seen of sucessfullt changing the slider colors has been through stylesheets.

Thanks for looking into this. I also notice when resizing the window (with the mouse) that the black border sometimes becomes transparent...

I also wanted to add that the black borders can also be observed with uicontrol's slider:

it also makes me notice that the display of the slider differs fropm Matlab: In Matlab, you have < on the left and > on the right, while in Octave you have < on the left and <> on the right.

For the black box, I didn't see anything that could be set to remove it.

For the listbox, the frame can be changed to something like a Panel which does get rid of the line (Which looks like is a StyledPanel)

However the popupmenu and edit control both only have options to either display the frame or don't display it.

Without any frame, it doesn't match a standard control.

It might be able to be done using stylesheets.

The black borders on edit, listbox and popupmenu are reported in bug #44704 so maybe this bug report can be closed as "fixed" and conversation continued there. Thanks!

Hi, I'm very impressed about the activities initiated by my error report. Cause I'm using only OCTAVE as an end-user (no source) I cannot contribute in testing but it seems to me that a future release will solve this problem so I stay on happy.
Thanks to all !

Thanks again, John. All foreground and background colors seem to work fine, see attachment. I would actually be curious to see how it displays on your computer and whether you also have the black borders.

Pushed http://hg.savannah.gnu.org/hgweb/octave/rev/96411a33f570 for additional color changes

You're right, I observe the same thing for popupmenu.

Guillaume <gyom>
Tue 11 Oct 2016 04:18:28 PM UTC, comment #9:

for popup menu, it looks like its the selected (non popup) part of the control that doesnt respect the color changes - inserting more items and popping it does use the colors.

I'll see if there is a way to make it use the colors when not 'popped' as well.

John, thanks! I can confirm that the backgroundcolors are now fine for pushbutton and radiobutton.

I also reran the script from bug #48255 to compare Octave and Matlab for all uicontrols:

and I can see four issues:

  • backgroundcolor of popupmenu
  • text color (ie foregroundcolor) of checkbox, popupmenu and radiobutton
  • checkbox and radiobutton default value
  • edit, listbox and popupmenu have a strange looking black border.

Ok - I see that on fedora too - at a quick glance it looks like radiobutton (and checkbox) colors are not handled the same as pushbutton and togglebutton (when they should be)

I also observe the issue under Linux (Octave 4.3.0+ on openSUSE 13.2) with the radiobutton, but it's fine with the pushbutton.

(file #38693)

There is a lot of discusion on changing colors of pushbuttons on the Qt website when using Windows.

It appears that the standard setPalette option used in linux does not work depending on the application style.

Leaving two options to fix

1. embed the background color in the style for the button (which may not work, or may cause issues with other styles are also set)

2. set the application style to 'Windows' instead of WindowsXp or WindowsVista.

The attached patch does the second option.

Does the same thing in the octave 4.2rc2 under windows.

Works fine for me, in fedora.

See also bug #48255 and perhaps bug #44704.

Guillaume <gyom>
Sun 02 Oct 2016 12:27:10 PM UTC, original submission:

Specifying backgroundcolor for pushbutton or radiobutton is ignored and simply gray is used. For pushbutton it seems to be a small box around the button with the backgroundcolor but not the button itself. Simple program example and result from OCTAVE and MATLAB is found in the attachement.
