Description Edward 2022-10-29 04:22:03 CEST

Description of problem:

Installed gtk2-theme-engines to see if changing the theme in LXDE would resolve Bug 31002, to discover that none of the themes that installed will actually be applied when selected. The only themes that will work/can be changed are Adwaita, Adwaita-dark and HighContrast, which are the three that were initially installed with LXDE.

Version-Release number of selected component (if applicable):

2.20.2-13


Steps to Reproduce:
1. Install gtk2-theme-engines (which will install five other packages)
2. Go to LXDE menu (Mageia icon)/Tools/Customize Look and Feel
3. On Widget tab, select one of the themes listed on the left. Other than the three mentioned above, none of the others will be applied or displayed when selected.

Thank you for this report.
I wonder whether the fault is offering GTK2 anything; I thought it was banished henceforth in favour of GTK3.
 However I found 9 gtk2 packages on my Cauldron system (45 in repos):
adwaita-gtk2-theme-3.28-9.mga9
gtk2-clearlooks-engine-2.20.2-13.mga9
gtk2-hc-engine-2.20.2-13.mga9
gtk2-murrine-engine-0.98.2-12.mga9
lib64cheese-gtk25-41.1-2.mga9
lib64dbusmenu-gtk2_4-16.04.1-1.20170109.5.mga9
lib64gtk2-clearlooks-engine-2.20.2-13.mga9
lib64gtk2-hc-engine-2.20.2-13.mga9
lib64gtk2-murrine-engine-0.98.2-12.mga9
 against 17 (87 in repos) citing gtk3.

Assigning to NicolasS for LXDE.

The Vertex theme comes in both GTK2 and GTK3 varieties. I installed the GTK3 package first, which also pulled in a few others including vertex-theme-common. On Customize Look and Feel, it was not even listed, so I uninstalled it and the associated packages.

Then installed the GTK2 package, which also installed gtk2- and lib64gtk2-murrine-engine and vertex-theme-common. The GTK2 Vertex appeared on Customize Look and Feel, but when selected, the theme did not change from Adwaita.

Hi,

Despite the fact that lxappearance is now built with GTK3 (Cauldron), the application only lists GTK2 themes, but assumes those themes have a GTK3 counterpart, to be able to set the same theme for all applications that use GTK2 and GTK3.

Since LXDE (Cauldron) is built with GTK3, a theme that is only available in GTK2, will not have a visible impact.

Best regards,

Hi,

lxappearance-0.6.3-3.git20220517.3.mga9 will solve that issue by only listing themes that are installed in GTK2 and GTK3.

Best regards,

Nico.
