Subject: bug#20619: Scrollbars
Date: Fri, 23 Dec 2016 21:30:17 +0100 [thread overview]
Message-ID: <932ffe0b-8e9e-5a47-1a3f-47df43f7be42@univ-fcomte.fr> (raw)
In-Reply-To: <555CD05C.4070303@stsci.edu>
So I have successfully compiled emacs 25.1.1 to make tests.
I applied the patch given in message #13, but it works partially, I will
discuss about it later.
Now, to advance emacs support for HIDPI I would like to fix the
scrollbar. Do all people here agree that the scrollbar has a width
twice as normal? The reason is that in src/gtkutil.c there is this code:
int
xg_get_default_scrollbar_width (void)
{
return scroll_bar_width_for_theme * xg_get_gdk_scale ();
}
where xg_get_gdk_scale returns GDK_SCALE variable, i.e. 2 in general.
If I replace with:
return scroll_bar_width_for_theme;
the scrollbar is shown correctly.
This change was made by
https://github.com/emacs-mirror/emacs/commit/c0055ff5b03c9121ab5bf752496b09416f0f0a7d.
I think there was an error there, or perhaps in the mean time (since
May 2015) GTK has changed in a way so that scrollbars are taken into
account.
Anyway, using "GTK_SCALE=2 emacs" shows correctly the scrollbar with my
proposition.
Note that GDK_DPI_SCALE is only for font, AFAIU from
https://developer.gnome.org/gtk3/stable/gtk-x11.html.
What do you think? Would you commit such a modification?
I would like to look into other issues as well.
