gtk-mouse settings are not saved

[agaida]

gtk-cursor-theme-name="Adwaita"
gtk-cursor-theme-size=0

The themes will set via lxqt-config-appearance, but not saved and not provided via xsettings - bad :(
Second - will file a new bug for, the cursor-theme-size can't be set.

On the fly it works:

Steps to reproduce:

1. Open Chrome or Brave broweser
2. Open lxqt-config-appearance and set a theme - hurray, it works.
3. Close both.
4. Open Browser again and be sad.

@yan12125 Please save me ;) @agaida assigned it to me too but I don't know about these things — had no role in their implementation.

[agaida]

:) - ok, i removed the hook for @tsujan, a bit more information. I used xfce query tool and was surprised - we set only a few things and ignore the very most possible settings - not that clever and it looks horrible.

Background

I was playing a browser game and noticed the fugly default black cursor. Was about to cry and had a look into

Our .xsettingsd

# Created by lxqt-config-appearance (DO NOT EDIT!)
Net/IconThemeName "Papirus"
Net/ThemeName "Adwaita"
Gtk/FontName "Noto Sans 10"
Gtk/MenuImages 1
Gtk/ButtonImages 1

Solution for me

# Created by lxqt-config-appearance (DO NOT EDIT!)
Net/IconThemeName "Papirus"
Net/ThemeName "Adwaita"
Gtk/FontName "Noto Sans 10"
Gtk/MenuImages 1
Gtk/ButtonImages 1
Gtk/ToolbarStyle "GTK_TOOLBAR_BOTH_HORIZ"
Gtk/CursorThemeName "Chameleon-Pearl-Large"

just added the Theme Name -- works as expected and filed this bug 😄

@selairi - we should implement it fully :)

Ok. I will fix it. El sábado, 4 de mayo de 2019, Alf Gaida <notifications@github.com> escribió:

Cool, thanks - don't know if there are other things xfconf-query missed. will test with Gnome and read a bit more about. Even if we don't provide all the things™ right now we should be prepared to do so.

Well, I don't quite understand xsettings either :O

I remember lxqt-config-appearance creates a temporary file and feed it to xsettingsd, so settings are not persistent?

[agaida]

Only spotted it when playing an online game and couldn't find my cursor - added the needed thing to .xsettingsfoo and xsettingsd picked it up right. So it is just an implementation detail.

[tsujan]

so settings are not persistent?

I guess they aren't complete. @selairi is the expert in GTK settings.

[selairi]

Hello, I have just upload the changes in: https://github.com/selairi/lxqt-config
It is ready to merge in master branch.

@yan12125 lxqt-config-appearance doesn't use .xsettingsd file. It only runs xsettingsd to alert to GTK applications about changes, then xsettingsd is killed (in order to save RAM). It is not needed run xsettingsd in your LXQt session, because GTK tools read their styles from gtkrc files.

[agaida]

ok - more verbose - the fact that the mouse style is saved now if fine and a great improvement. When i talk about complete (or nearly complete implementation) i thought about something like that:

possible	we provide	should be implemented
/Gdk/WindowScalingFactor
/Gtk/ButtonImages	Gtk/ButtonImages 1	implemented
/Gtk/CanChangeAccels
/Gtk/ColorPalette
/Gtk/CursorThemeName	Gtk/CursorThemeName "Chameleon-Pearl-Large"	implemented
/Gtk/CursorThemeSize
/Gtk/DecorationLayout
/Gtk/FontName	Gtk/FontName "Noto Sans 10"	implemented
/Gtk/IconSizes
/Gtk/KeyThemeName
/Gtk/MenuBarAccel
/Gtk/MenuImages	Gtk/MenuImages 1	implemented
/Gtk/MonospaceFontName
/Gtk/ToolbarIconSize
/Gtk/ToolbarStyle	Gtk/ToolbarStyle "GTK_TOOLBAR_BOTH_HORIZ"	implemented
/Net/CursorBlink
/Net/CursorBlinkTime
/Net/DndDragThreshold
/Net/DoubleClickDistance
/Net/DoubleClickTime
/Net/EnableEventSounds
/Net/EnableInputFeedbackSounds
/Net/IconThemeName	Net/IconThemeName "Papirus"	implemented
/Net/SoundThemeName
/Net/ThemeName	Net/ThemeName "Adwaita"	implemented
/Xfce/LastCustomDPI		xfce - not needed
/Xft/Antialias
/Xft/DPI
/Xft/Hinting
/Xft/HintStyle
/Xft/RGBA

So i guess we have plenty room for improvement - and we should improve that, maybe a first step would be to select the things we neee, want to have or can ignore.

This table is based on xfconf-query, so i don't know if the list is complete.

[selairi]

@agaida This is a good point. There are lots of GTK properties that are not set by LXQt and we should set them by default or build new interfaces to select them.

Example, "Net/SoundThemeName" is the XDG sound theme to use for event sounds. This is not set by LXQt. Should we set it by default or write a tool to select sounds? In this case, I would like to set no sound by default, I love silence.

To my mind, we should agree on the default GTK values and we should not write more interfaces.

[selairi]

My suggestions for default values or to add to LXQt are:

possible	we provide	should be implemented
/Gdk/WindowScalingFactor	It depends on Openbox/Kwin settings	ignore it
/Gtk/ButtonImages	Gtk/ButtonImages 1	implemented
/Gtk/CanChangeAccels	This setting is ignored by GTK 3.10	ignore it
/Gtk/ColorPalette	This setting is ignored by GTK 3.10	ignore it
/Gtk/CursorThemeName	Gtk/CursorThemeName "Chameleon-Pearl-Large"	implemented
/Gtk/CursorThemeSize		Now, it seems work properly
/Gtk/DecorationLayout	This setting determines which buttons should be put in the titlebar of client-side decorated windows, and whether they should be placed at the left of right.	Set to "menu:minimize,maximize,close"
/Gtk/FontName	Gtk/FontName "Noto Sans 10"	implemented
/Gtk/IconSizes		should be implemented
/Gtk/KeyThemeName	Name of key theme to load.	LXQt doesn't set this. ignore it
/Gtk/MenuBarAccel	has been deprecated	ignore it
/Gtk/MenuImages	Gtk/MenuImages 1	implemented
/Gtk/MonospaceFontName		We should implement it and add it to fonts config
/Gtk/ToolbarIconSize
/Gtk/ToolbarStyle	Gtk/ToolbarStyle "GTK_TOOLBAR_BOTH_HORIZ"	implemented
/Net/CursorBlink	Whether the cursor should blink.	it should set to false
/Net/CursorBlinkTime
/Net/DndDragThreshold		we should set LXQt values
/Net/DoubleClickDistance		we should set LXQt values
/Net/DoubleClickTime		we should set LXQt values
/Net/EnableEventSounds		set to false
/Net/EnableInputFeedbackSounds
/Net/IconThemeName	Net/IconThemeName "Papirus"	implemented
/Net/SoundThemeName
/Net/ThemeName	Net/ThemeName "Adwaita"	implemented
/Xfce/LastCustomDPI		xfce - not needed
/Xft/Antialias		we should set LXQt values
/Xft/DPI		we should set LXQt values
/Xft/Hinting		we should set LXQt values
/Xft/HintStyle		we should set LXQt values
/Xft/RGBA		we should set LXQt values

Having some problems with this on a recent install (1 week ago, have no idea why previous install worked fine) the cursor size on chromium-based browsers (tested brave, chromium and vivaldi) is huge (probably double, at 48px), when changing the cursor size on lxqt-config-appearance it works until logoff, so i guess xsettingsd sets it, but it doesnt persist.

might be relevant: my monitor config is weird:

top one is a 42 inch tv and bottom is 27 inch monitor, both 1080p, and if i dont disable QT_AUTO_SCALE it breaks qbittorrent's ui, so it could have something to do with HiDPI and how GTK or chromium handles it.

my hacky fix is add desired cursor size in $HOME/.config/gtk-3.0/settings.ini like gtk-cursor-theme-size = 24 and run a script on autostart with inotifywait in a loop to ensure it gets set again when the file is changed, should this be set by lxqt-config?
