Picture of what my problem is.
Going from Debian Jessie to Stretch there seems to be padding added to the datetime-plugin (clock + date shown in taskbar). I like my panel tiny, and the introduced padding pushes the date out of bounds.
I am not familiar with it, but I thought maybe I could get rid of the padding via an override in my gtkrc file? I already use that file to get my desktop icons closer together.
Some resources I have found:
https://wiki.gnome.org/Attic/GnomeAr...ials/GtkThemes
https://developer.gnome.org/gtk3/stable/ch02.html
https://www.gtk.org/tutorial1.2/gtk_tut-21.html
Most sources talk about applying a global theme; that is the opposite of what I want to do. I want to override the style of a single element of a single application. So I need to get a specific GTK path?
I would like to add something like this my gtkrc-2.0:
Code:
style "my-clock-is-broken" {
padding = 0
}
widget "Datetime.*" style "my-clock-is-broken"
So I would need the name of the "window" the datetime plugin runs in? When I run "xwininfo -root -children" it seems the datetime plugin runs in an anonymous window?
Code:
xwininfo: Window id: 0x1dc (the root window) (has no name)
Root window id: 0x1dc (the root window) (has no name)
Parent window id: 0x0 (none)

Here is some relevant source code of the datetime plugin:
Code:
/*
* create the gtk-part of the datetime plugin
*/
static void datetime_create_widget(t_datetime * datetime)
{
GtkOrientation orientation;
orientation = xfce_panel_plugin_get_orientation(datetime->plugin);
/* create button */
datetime->button = xfce_create_panel_toggle_button();
gtk_widget_show(datetime->button);
/* create a box which can be easily adapted to the panel orientation */
datetime->box = gtk_box_new(GTK_ORIENTATION_VERTICAL, 0);
gtk_widget_show(datetime->box);
gtk_container_add(GTK_CONTAINER(datetime->button), datetime->box);
/* create time and date lines */
datetime->time_label = gtk_label_new("");
datetime->date_label = gtk_label_new("");
gtk_label_set_justify(GTK_LABEL(datetime->time_label), GTK_JUSTIFY_CENTER);
gtk_label_set_justify(GTK_LABEL(datetime->date_label), GTK_JUSTIFY_CENTER);
/* add time and date lines to the box */
gtk_box_pack_start(GTK_BOX(datetime->box),
datetime->time_label, TRUE, FALSE, 0);
gtk_box_pack_start(GTK_BOX(datetime->box),
datetime->date_label, TRUE, FALSE, 0);
/* connect widget signals to functions */
g_signal_connect(datetime->button, "button-press-event",
G_CALLBACK(datetime_clicked), datetime);
/* set orientation according to the panel orientation */
datetime_set_mode(datetime->plugin, orientation, datetime);
}
But I guess my effort ends when there is no window name associated with the plugin? Anybody who wants to chime in is welcome. I guess I could compile an altered version of the plugin... after learning GTK and preparing a build environment for XFCE... I don't think I'm that desperate yet.
