xfce4-equake-plugin problem on epel7

[Jeroen van Aart]

(sent to xfce4-dev last January but there was no reply, I should add 
that when I expand the panel in vertical size it will show more of the 
text but never all of it)

On rhel7 with xfce4* including xfce4-equake-plugin installed from the 
epel7 repository I noticed that when I add the plugin to the panel it 
does not show the text fully. Basically it shows the small icon and 
about one and a half character. Normally it should show the full text 
displaying the most current earthquake event.

It looks like for some reason the plugin is not receiving a resize event 
and/or the panel does not allow it to resize.

This problem does not occur on any other distributions which have the 
plugin available such as fedora 25, ubuntu 16.04, debian testing, mint. 
All are based on the same source with minor or no changes.

The version of the panel on epel7 is:

xfce4-panel-4.12.0-4.el7.x86_64.rpm

The rpm packages of the olugin:

https://apps.fedoraproject.org/packages/xfce4-equake-plugin/overview/

I don't think filing a bug report is necessary (yet), because the 
problem is limited to epel7 only and may already have been fixed, since 
it works on fedora 25.

However does anyone know which potential bug would cause this and if 
there is a work around that doesn't require a patch of the source of the 
panel or waiting for a patched epel7 package to arrive? Perhaps all that 
is needed is a configuration change somewhere.

Below you can see an example of code I use to change the size. If I 
recall correctly I adapted this from an example as being the way one is 
supposed to notice and respond to size and orientation changes, but my 
memory is sketchy since it's been a while. As I said this works fine on 
any other xfce4 panel versions I have tried.


static void example_orientation_changed(XfcePanelPlugin *applet, 
GtkOrientation orientation, struct Example_Data *exampledata)
{
   orientation=xfce_panel_plugin_get_orientation(applet);
   xfce_hvbox_set_orientation(XFCE_HVBOX(exampledata->hbox), orientation);
}

static void example_size_changed(XfcePanelPlugin *applet, int size, 
struct Example_Data *exampledata)
{
   GtkOrientation orientation;
   orientation=xfce_panel_plugin_get_orientation(applet);

   if (orientation==GTK_ORIENTATION_HORIZONTAL)
     gtk_widget_set_size_request(GTK_WIDGET(applet), -1, size);
   else
     gtk_widget_set_size_request(GTK_WIDGET(applet), size, -1);
}

I create the following relevant signal callbacks:

g_signal_connect(G_OBJECT (applet), "size-changed", G_CALLBACK 
(example_size_changed), exampledata);
g_signal_connect(G_OBJECT (applet), "orientation-changed", G_CALLBACK 
(example_orientation_changed), exampledata);
