Gtk: How to remove padding around LinkButton

[borjafdezgauna]

Hi there!
I have been trying to remove the padding around LinkButton on Linux (using Gtk) and I haven't been able to do it.

This is what I get:

with this code:

var row = new StackLayout() { Orientation = Orientation.Horizontal, Spacing = 10 };
 row.Items.Add(new Label() { Text = "Label" });
 LinkButton button = new LinkButton() { Text = "Button" };
 row.Items.Add(button);

Actually, the label appeared in the middle of the colored block. I have moved it a bit up by doing this:

Eto.Style.Add<Control>(null, c =>
            {
                c.LoadComplete += (sender, e) =>
                {
                    if (c.Handler is Eto.GtkSharp.Forms.IGtkControl handler)
                    {
                        if (handler is Eto.GtkSharp.Forms.Controls.LinkButtonHandler linkButton)
                        {
                            linkButton.TextColor = XerkaCore.Framework.Styles.LinkColor;
                            linkButton.ContainerControl.Margin = 0;

                            if (linkButton.Control.Parent is Gtk.EventBox eventBox)
                            {
                                linkButton.Control.Yalign = 0;
                             }

I would like to remove the padding space around the LinkButton so that both the label and it are vertically aligned in a horizontal StackLayout.... any idea???

Thanks!!!

In case someone has this same problem, I managed to remove the padding around the buttons (not 100% perfect but enough for me) by adding a custom LinkButtonHandler:

I basically copied the exisiting handler in Eto and changed the constructor to apply Css styling on the button (I renamed it to GtkLinkButtonHandler because I had some issues with namespaces):

public GtkLinkButtonHandler()
{
  var provider = new Gtk.CssProvider();
  Gtk.StyleContext.AddProviderForScreen(Gdk.Screen.Default, provider, uint.MaxValue);          
  provider.LoadFromData("#linkButton {padding: 0;}");			
  Control = new Gtk.LinkButton(string.Empty);
  (Control as Gtk.LinkButton).Name = "linkButton";
  Control.Xalign = 0f;
  Control.Yalign = 0f;
  Control.TooltipText = null;
  box = new Gtk.EventBox();
  box.Child = Control;
}

And then, before running my app:

platform.Add(typeof(Eto.Forms.LinkButton), () => new GtkLinkButtonHandler());
