Summary: When I was running //GTK3// application //pavucontrol//, I was getting warnings: ``` (pavucontrol:10863): Gtk-WARNING **: 10:09:55.669: Theme parsing error: gtk.css:127:35: The style property GtkButton:child-displacement-x is deprecated and shouldn't be used anymore. It will be removed in a future version (pavucontrol:10863): Gtk-WARNING **: 10:09:55.669: Theme parsing error: gtk.css:128:35: The style property GtkButton:child-displacement-y is deprecated and shouldn't be used anymore. It will be removed in a future version (pavucontrol:10863): Gtk-WARNING **: 10:09:55.669: Theme parsing error: gtk.css:129:34: The style property GtkCheckButton:indicator-size is deprecated and shouldn't be used anymore. It will be removed in a future version (pavucontrol:10863): Gtk-WARNING **: 10:09:55.669: Theme parsing error: gtk.css:130:36: The style property GtkCheckMenuItem:indicator-size is deprecated and shouldn't be used anymore. It will be removed in a future version (pavucontrol:10863): Gtk-WARNING **: 10:09:55.669: Theme parsing error: gtk.css:132:46: The style property GtkScrolledWindow:scrollbars-within-bevel is deprecated and shouldn't be used anymore. It will be removed in a future version (pavucontrol:10863): Gtk-WARNING **: 10:09:55.669: Theme parsing error: gtk.css:135:30: The style property GtkExpander:expander-size is deprecated and shouldn't be used anymore. It will be removed in a future version (pavucontrol:10863): Gtk-WARNING **: 10:09:55.669: Theme parsing error: gtk.css:142:29: The style property GtkStatusbar:shadow-type is deprecated and shouldn't be used anymore. It will be removed in a future version ``` This was annoying, so I decided to fix it. Firstly I thought it is a application problem, but then I discovered it is //breeze-gtk// issue. For example //GTK3// documentation states that: > GtkStatusbar:shadow-type has been deprecated since version 3.20 and should not be used in newly-written code. > > Use CSS properties to determine the appearance, the value of this style property is ignored. So if some styles are ignored, I can remove them and get rid of part of warnings: # I wrote python script for finding all deprecation messages in docs: {F6614333} # I ran script and saved results to file # I used it to find all ignored properties in CSS: ``` $ find-deprecated-styles.py > /tmp/gtk-deprecated.txt $ cd breeze-gtk/src/gtk320/ $ cat /tmp/gtk-deprecated.txt | sed -n 's/^ \* \([^ ]*\).*the value of this style property is ignored.*$/\1/p' | tr : - | while read style; do grep -Rn $style; done widgets/_base.scss:40: -GtkStatusbar-shadow-type: none; widgets/_base.scss:12: -GtkButton-child-displacement-x: 0; widgets/_base.scss:13: -GtkButton-child-displacement-y: 0; widgets/_base.scss:16: -GtkCheckMenuItem-indicator-size: 18; widgets/_base.scss:24: -GtkScrolledWindow-scrollbars-within-bevel: 0; ``` Then I just removed them. **Edit:** I checked and there was two more deprecated styles, which require a little work: ``` $ cat /tmp/gtk-deprecated.txt | sed -n 's/^ \* \([^ ]*\).*CSS.*$/\1/p' | tr : - | while read style; do gre p -Rn $style; done widgets/_base.scss:24: -GtkExpander-expander-size: 16; widgets/_base.scss:12: -GtkCheckButton-indicator-size: 18; ``` According to documentation ([[ https://developer.gnome.org/gtk3/stable/GtkCheckButton.html#GtkCheckButton--s-indicator-size | 1 ]], [[ https://developer.gnome.org/gtk3/stable/GtkExpander.html#GtkExpander--s-expander-size | 2 ]]) //min-width// and //min-height// should be used instead of them.
